Definitions
- the invention relates to a laundry detergent composition with additional property of softening and a laundry detergent obtained with this composition.
- the problems may occur during the dissolution of the power detergents or the granule soaps in the water and the residues may remain on the textile product during the washing.
- the residues may remain on the textile product during the washing.
- the detergents intended for the baby clothes are used, the optical brightener residues may remain on the textile, as some detergents comprise the optical brighteners enabling the textile to look brighter.
- the residues remaining on the textile may lead to irritation and allergy in the skin in the long term.
- Using the baby laundry detergents alone is not sufficient to achieve the desired softness in the textile. It is necessary to use additional products with the softening property in order to achieve the desired softness.
- the baby laundry detergents Due to their necessity to be more natural than the adult laundry detergents, the baby laundry detergents have a different structure. They contain the raw materials that are milder and of natural origin. Some parents prefer the granule soaps that are free of synthetic surfactants, since such products are even more natural. The disadvantages of the granule soaps compared to the detergents are that they are difficult to rinse from the clothes and that they leave residues on the clothes as a result of their granular form. The raw material residues remaining on the clothes worn throughout the day may contact the skin and cause sensitivity, irritation and allergy in the skin.
- the softeners may further cause the textiles to turn gray in the course of time. Because the softeners are not of vegetable origin or because they leave residues on the textile, some parents avoid using the softeners and they opt for textiles with smaller extent of softness than the expectations.
- An object of the invention is to develop a laundry detergent composition with softening property. Another object of the invention is to develop a laundry detergent with softening property.
- Another object of the invention is to develop a laundry detergent, which is suitable for use in washing the baby products also.
- Another object of the invention is to develop a laundry detergent, which leaves no residue on the washed textile product.
- Another object of the invention is to develop a detergent, which is free of allergens and is possible to be used also by the persons with sensitive skin.
- Another object of the invention is to develop a laundry detergent, which is of vegetable origin and is hypoallergenic.
- Another object of the invention is to develop a laundry detergent, which does not include dyestuffs and optical whiteners.
- the invention relates to a laundry detergent composition with additional property of softening and a laundry detergent obtained with this composition.
- a laundry detergent composition and a laundry detergent possible to be used for washing the baby textile products have been developed within the scope of the invention.
- the textiles will be enabled to be softer without leaving any residue on the textiles.
- the baby laundry detergent is enabled to be suitable also for the sensitive skins, by using the allergen-free essences in said product. Since the product is preferably in liquid form, it is readily soluble in water. It is of vegetable origin and is hypoallergenic.
- the baby laundry detergent developed with the invention does not include dyestuffs and optical whiteners in its composition.
- the textile product is conferred the softness and flexibility owing to the active ingredients of vegetable origin and at least one type of protein added to the product according to the invention.
- the baby textiles will be enabled to be soft, have a pleasant smell and preserve their shape following the wash performed by the use of a single product. Owing to the developed product, the problem of textiles that gray in the course of time encountered in the state of the art will also be precluded.
- the laundry detergent composition according to the invention comprises in its most basic form at least one type of oil and/or fatty acid, at least one type of alkaline agent, at least one type of chelating agent and at least one type of nonionic surfactant of natural origin.
- the soaps are the sodium or potassium salts of the oils or fatty acids.
- the temperature should be increased. It was observed that the soap could solidify when the suitable conditions and concentration are not provided.
- the use of fatty acid is preferred instead of oil in order to obtain the soap in a faster, more efficient and more sustainable manner.
- the cleaning action of the soap stems from the ability of the hydrophobic part present in the structure of the soap to surround the particles of oil/dirt.
- the cleaning action of the soap is enhanced with the fatty alcohol ethoxylates with different carbon chain lengths, fatty alcohol ethoxylate propoxylates with different carbon chain lengths, alkyl polyglycosides and emulsifying nonionic surfactants used within the scope of the invention.
- the nonionic surfactants having a carbon chain distribution in the range of C10-C18 and including 3-12 ethylene oxide groups are used.
- the combined used of hydrophilic and hydrophobic nonionic surfactants may affect the performance in the liquid laundry detergents. Accordingly, the combined use of the nonionic surfactants with different ethylene oxide values is also possible to encounter.
- the hydrophilic- lipophilic balance (HLB) value of the nonionic surfactants is in the range of 3-25, said value is generally in the range of 6-15 for the raw materials used, and the surfactants having a HLB value preferably in the range of 10-15 are used in the laundry detergents.
- HLB hydrophilic- lipophilic balance
- anionic surfactants and the amphoteric surfactants may be used together.
- the use of anionic surfactants is preferred mainly for their stain removal property.
- their high foam amounts bring about the requirement to use the foam control agents simultaneously.
- all the textile surfaces are negatively charged, except for some natural and synthetic fabrics.
- the solubilizer group of the anionic surfactants used in the detergents is negatively charged and, when present alone in the formulation, they are unable to completely dissolve the stains during the wash. Due to the foaming problem, they cause and their irritant properties, the anionic surfactants were not used within the scope of the invention.
- composition according to the invention comprises at least one nonionic surfactant or a mixture of several nonionic surfactants preferably selected from fatty alcohol ethoxylates having a carbon chain distribution in the range of C10-C18 and including 3-12 ethylene oxide groups, alkyl polyglycosides and oleyl glucamide as the nonionic surfactant.
- Polycarboxylates, copolymers, aminocarboxylates, aminopolycarboxylates and citrates may be used as the dispersing agent and chelating agent in the product developed within the scope of the invention.
- the chelating agents are used to reduce the hardness originating from the utility water and to enable the dispersion of the stain in the wash solution.
- the chelating agents such as HEDP and PBTC are used in the state of the art.
- both raw materials contain phosphorus in their structure. Since the release of phosphorus along with the wash waters into the environment harms the environment, the alternative agents were studied for being added to the composition within the scope of the invention.
- the softeners are used for the purpose of softening the textiles.
- the softeners are added to the wash water in the rinsing step of the laundry process and, by remaining on the textile, they enable the textile to soften and to have a pleasant smell.
- Esterquats having a cationic structure are generally used in the softeners.
- the softeners that contain a cationic surfactant may lead the textile to gray in the course of time.
- a surfactant which is of natural origin and has the softening property, was employed. As a result, there was no need to use additional products, which damage the textile or cause adverse effects on the skin, in order to confer the ability of softening to the product.
- the laundry detergent composition according to the invention comprises at least one type of oil and/or fatty acid for use in the saponification reaction.
- the use of at least one type of oil or a mixture of several oils selected from but not limited to coconut oil, shea butter, cocoa butter, castor oil, laurel oil, olive oil, black cumin oil, palm oil and turpentine oil is preferred. It is observed that the saponification reaction can occur at elevated temperatures in case oil is used. It is further noticed that the soap could solidify in case suitable conditions and concentrations may not be provided.
- the product is required to be in a liquid and homogeneous form. Consequently, the fatty acids of the mentioned alternatives of oil were also used in the preferred embodiment of the invention.
- a preferred embodiment of the invention comprises the coconut fatty acid as the fatty acid and/or olive oil as the oil.
- At least one type of alkaline agent is used within the scope of the invention.
- the soap is a sodium and/or potassium salt
- the alkaline agents possible to be used for the realization of the saponification reaction include, but are not limited to, at least one alkaline agent or a mixture of alkaline agents selected from sodium hydroxide and potassium hydroxide.

Description
LAUNDRY DETERGENT COMPOSITION WITH SOFTENING PROPERTY AND LAUNDRY DETERGENT COMPRISING SAID COMPOSITION
Subject of the Invention
The invention relates to a laundry detergent composition with additional property of softening and a laundry detergent obtained with this composition.
State of the Art
There are different properties sought by the consumers when buying a detergent. A wash performance at the expected level, the nature-friendly feature of a product and the pleasant smell of a product may be mentioned among these properties. When these properties are considered with regard to a baby laundry detergent, the parents attach as much importance to a detergent's being free of dangerous chemicals as the level of stain removal performance expected from the detergent. Some parents additionally desire to have a pleasant smell in the clothes. In addition to all these expectations, considering the sensitivity of the skin of the babies, it is important to ensure that no detergent residue remains on the textile product contacting the skin of the babies and further ensure that the clothes are soft.
The problems may occur during the dissolution of the power detergents or the granule soaps in the water and the residues may remain on the textile product during the washing. In order to eliminate the residues, it is necessary to carry our extra rinsing. In case the detergents intended for the baby clothes are used, the optical brightener residues may remain on the textile, as some detergents comprise the optical brighteners enabling the textile to look brighter. Considering the sensitive and permeable structure of the baby skin, the residues remaining on the textile may lead to irritation and allergy in the skin in the long term.
Using the baby laundry detergents alone is not sufficient to achieve the desired softness in the textile. It is necessary to use additional products with the softening property in order to achieve the desired softness.
Due to their necessity to be more natural than the adult laundry detergents, the baby laundry detergents have a different structure. They contain the raw materials that are milder and of natural origin. Some parents prefer the granule soaps that are free of synthetic surfactants, since such products are even more natural. The disadvantages of the granule soaps compared to the detergents are that they are difficult to rinse from the clothes and that they leave residues on the clothes as a result of their granular form. The raw material residues remaining on the clothes worn throughout the day may contact the skin and cause sensitivity, irritation and allergy in the skin.
It is required to use a separate softener in addition to the detergent or soap in order to achieve softness and pleasant smell in the textile. Accordingly, it is a must to use more than one product in order to satisfy all the needs. The softeners may further cause the textiles to turn gray in the course of time. Because the softeners are not of vegetable origin or because they leave residues on the textile, some parents avoid using the softeners and they opt for textiles with smaller extent of softness than the expectations.
Consequently, conferring the textile-softening property to the detergents while at the same time obtaining a product that would not leave residues on the textile is a problem of the state of the art that needs to be solved. In order to provide a solution for the above- mentioned problem, a laundry detergent, which has the softening property and which is possible to be used for washing the baby products also, has been developed within the scope of the invention.

Another object of the invention is to develop a laundry detergent, which does not include dyestuffs and optical whiteners.
Detailed Description of the Invention
The invention relates to a laundry detergent composition with additional property of softening and a laundry detergent obtained with this composition.
A laundry detergent composition and a laundry detergent possible to be used for washing the baby textile products have been developed within the scope of the invention. Owing to the product developed within the scope of the invention, the textiles will be enabled to be softer without leaving any residue on the textiles. The baby laundry detergent is enabled to be suitable also for the sensitive skins, by using the allergen-free essences in said product. Since the product is preferably in liquid form, it is readily soluble in water. It is of vegetable origin and is hypoallergenic. The baby laundry detergent developed with the invention does not include dyestuffs and optical whiteners in its composition. The textile product is conferred the softness and flexibility owing to the active ingredients of vegetable origin and at least one type of protein added to the product according to the invention. In
this way, the baby textiles will be enabled to be soft, have a pleasant smell and preserve their shape following the wash performed by the use of a single product. Owing to the developed product, the problem of textiles that gray in the course of time encountered in the state of the art will also be precluded.
The laundry detergent composition according to the invention comprises in its most basic form at least one type of oil and/or fatty acid, at least one type of alkaline agent, at least one type of chelating agent and at least one type of nonionic surfactant of natural origin.
The soaps are the sodium or potassium salts of the oils or fatty acids. In order for the saponification reaction to occur, the temperature should be increased. It was observed that the soap could solidify when the suitable conditions and concentration are not provided. In the present invention, the use of fatty acid is preferred instead of oil in order to obtain the soap in a faster, more efficient and more sustainable manner.
The cleaning action of the soap stems from the ability of the hydrophobic part present in the structure of the soap to surround the particles of oil/dirt. The cleaning action of the soap is enhanced with the fatty alcohol ethoxylates with different carbon chain lengths, fatty alcohol ethoxylate propoxylates with different carbon chain lengths, alkyl polyglycosides and emulsifying nonionic surfactants used within the scope of the invention.
When the use of the fatty alcohol ethoxylates is preferred as the nonionic surfactant in the detergent composition, the nonionic surfactants having a carbon chain distribution in the range of C10-C18 and including 3-12 ethylene oxide groups are used. The combined used of hydrophilic and hydrophobic nonionic surfactants may affect the performance in the liquid laundry detergents. Accordingly, the combined use of the nonionic surfactants with different ethylene oxide values is also possible to encounter. Moreover, the hydrophilic- lipophilic balance (HLB) value of the nonionic surfactants is in the range of 3-25, said value is generally in the range of 6-15 for the raw materials used, and the surfactants having a HLB value preferably in the range of 10-15 are used in the laundry detergents. Moreover, when the alkyl polyglycosides were used as the nonionic surfactant, these raw materials
were observed to positively contribute to the low temperature resistance and product stability.
The anionic surfactants and the amphoteric surfactants may be used together. The use of anionic surfactants is preferred mainly for their stain removal property. However, their high foam amounts bring about the requirement to use the foam control agents simultaneously. On the other hand, all the textile surfaces are negatively charged, except for some natural and synthetic fabrics. The solubilizer group of the anionic surfactants used in the detergents is negatively charged and, when present alone in the formulation, they are unable to completely dissolve the stains during the wash. Due to the foaming problem, they cause and their irritant properties, the anionic surfactants were not used within the scope of the invention.
The composition according to the invention comprises at least one nonionic surfactant or a mixture of several nonionic surfactants preferably selected from fatty alcohol ethoxylates having a carbon chain distribution in the range of C10-C18 and including 3-12 ethylene oxide groups, alkyl polyglycosides and oleyl glucamide as the nonionic surfactant.
Polycarboxylates, copolymers, aminocarboxylates, aminopolycarboxylates and citrates may be used as the dispersing agent and chelating agent in the product developed within the scope of the invention. The chelating agents are used to reduce the hardness originating from the utility water and to enable the dispersion of the stain in the wash solution. Forthis purpose, the chelating agents such as HEDP and PBTC are used in the state of the art. However, both raw materials contain phosphorus in their structure. Since the release of phosphorus along with the wash waters into the environment harms the environment, the alternative agents were studied for being added to the composition within the scope of the invention.
According to the state of the art, the softeners are used for the purpose of softening the textiles. The softeners are added to the wash water in the rinsing step of the laundry process and, by remaining on the textile, they enable the textile to soften and to have a pleasant smell. Esterquats having a cationic structure are generally used in the softeners.
The softeners that contain a cationic surfactant may lead the textile to gray in the course of time. In the study conducted within the scope of the invention, a surfactant, which is of natural origin and has the softening property, was employed. As a result, there was no need to use additional products, which damage the textile or cause adverse effects on the skin, in order to confer the ability of softening to the product.
The laundry detergent composition according to the invention comprises at least one type of oil and/or fatty acid for use in the saponification reaction. In the developed product, the use of at least one type of oil or a mixture of several oils selected from but not limited to coconut oil, shea butter, cocoa butter, castor oil, laurel oil, olive oil, black cumin oil, palm oil and turpentine oil is preferred. It is observed that the saponification reaction can occur at elevated temperatures in case oil is used. It is further noticed that the soap could solidify in case suitable conditions and concentrations may not be provided. According to the object of the invention, the product is required to be in a liquid and homogeneous form. Consequently, the fatty acids of the mentioned alternatives of oil were also used in the preferred embodiment of the invention.
A preferred embodiment of the invention comprises the coconut fatty acid as the fatty acid and/or olive oil as the oil.
In addition to the oil and/or the fatty acid, at least one type of alkaline agent is used within the scope of the invention.
