Description

Detergent composition, shampoo soap containing the same and preparation method thereof

Technical Field

The invention relates to a washing composition, a shampoo soap containing the washing composition and a preparation method of the shampoo soap, in particular to a non-soap multifunctional washing composition, a shampoo soap containing the washing composition and a preparation method of the shampoo soap, and belongs to the field of daily chemical products.

Background

As a washing product in daily life, a washing composition (soap) mainly contains sodium higher fatty acid, and has been developed for more than two thousand years and is initially defined as: the detergent is prepared by taking oil and fatty acid as raw materials and performing saponification or neutralization reaction with potassium hydroxide or sodium hydroxide, and the raw materials are derived from vegetable oil or animal oil, are nontoxic, harmless, free of side effects on human bodies, easy to biodegrade and environmentally friendly, and are considered to be green and natural washing products. However, in the processing process, the pH value of the soap is usually about 10 due to the addition of excessive alkali, and compared with the weak acidic state of the skin surface of a human body, the soap is more irritant, the pH value of the skin surface layer is easily changed after long-term use, a sebum membrane is damaged, the skin is easily dried and loses elasticity, and skin allergy is easily caused for sensitive skin. In addition, the soap has poor low-temperature water solubility and poor washing effect in hard water, which greatly limits the application space of the fatty acid sodium soap.

Moreover, the performance of the soap cannot be greatly improved in structural adjustment alone, the production process and the cost are easily improved, and some mild surfactants must be compounded to prepare the composite soap, so that the pH value of the soap is reduced and the mildness of the soap is improved; on the other hand, the surfactant can be used as a lime soap dispersing agent to improve the washing performance of the soap in hard water, so that the functional application field of the soap is expanded. On the premise of ensuring the washing effect, different kinds of functional auxiliary raw materials can be added, the requirements of different people on the product effect are specifically met, and the multifunctional soap is called as a multifunctional soap, such as a beauty soap, a medicated soap, a slimming soap, an antibacterial and anti-inflammatory soap and the like.

At present, the formula of the shampoo soap block mainly comprises three main types: one is obtained by saponification of vegetable oil with caustic alkali. For example, cited document 1 discloses a method for preparing a pure natural plant shampoo soap, which is obtained by saponifying olive oil, camellia oil, coconut oil and palm oil in an alkaline environment, and although the product is natural and environment-friendly, the pH value of the product is high, soap scale deposition is easily generated in the hair washing process, and the forming process is a cold soap cutting and pressing process, so that the time is long and the yield is low.

The second type of shampoo soap formula is mainly a composite soap, for example, a conditioning solid shampoo soap is disclosed in cited document 2, wherein the proportion of natural soap base is 70-85%; 5-25% of synthetic washing surfactant, wherein 4-8% of cocoyl monoethanolamine, and the raw material is proved to have irritation to skin and eyes; the conditioner comprises 0.25-3.5% of conditioning agent components, wherein the polydimethylsiloxane accounts for 0.1-1%, and the silicone oil is insoluble in water, is not easy to completely remove in the flushing process, is attached to hair, enables the hair to be sticky, is easy to block pores, and affects the root health of the hair.

The third type of shampoo soap formula is surfactant-based, non-soap system. For example, cited reference 3 discloses a shampoo soap and a preparation method thereof, wherein a plurality of essential oils and conditioners are added into a shampoo soap base which is mainly composed of sodium lauryl sulfate and edible gum, and the shampoo soap is pressed by a pneumatic press to obtain a translucent solid shampoo soap. Further, as in the cited document 4, a mild surfactant, sodium cocoyl isethionate SCI-75, is used as a main component, and five-cereal flour, fruit powder and amino acid raw materials are mixed and extruded to prepare the shampoo soap solid. However, although the foaming power of the single anionic surfactant system is strong, the foam is large and not fine, which is not beneficial to washing, and the combing property of the wet hair and the dry hair is poor.

Therefore, it is an urgent need to solve the technical problem of developing a detergent composition which is mild, non-irritating, high in degreasing power, excellent in foaming performance in hard water, and excellent in water-flushing easiness during use.

Further, the second aspect of the invention also provides a preparation method of the shampoo soap, which comprises the steps of mixing the components of the washing composition and then forming.

In some embodiments, during the mixing process, it is necessary to use mechanical stirring to mix the components uniformly. Specifically, when the mixing time is 5 to 30min, preferably 10 to 15min, the alkyl sulfate surfactant particles can be uniformly maintained.

The mechanical agitation is not particularly limited in the present invention, and may be any mechanical agitation means commonly used in the art, for example, kneader agitation, etc.

In some specific embodiments, the present invention is not particularly limited to the forming method, and may be some forming methods commonly used in the art. Preferably, the molding method of the present invention may be tablet molding.

In the present invention, the pressure for molding is not particularly limited, and may be set as needed. Preferably, in the present invention, the pressure for tablet forming is 20 to 70psi, preferably 30 to 70psi, for example: 35psi, 40psi, 50psi, 60psi, etc. In the tabletting process, the product can be kept compact and has no gap inside, no cracking phenomenon exists in the practical use, the durability and the breakage are low, the whole process is carried out at room temperature, no humidity requirement exists, no polymer adhesive is required to be additionally added, the process is simple, the operation is easy, and the industrial production is convenient.

In addition, the apparatus for tabletting and the weight of the shampoo soap after molding are not particularly limited in the present invention, and the weight of the shampoo soap can be controlled as required by treating with a common tabletting machine. Specifically, the uniformly mixed materials are added into a feed hopper of a tablet press, the materials are conveyed to a tablet pressing groove through a conveying belt, the weight of the product is accurately controlled through a built-in quality sensor, and the gram weight of the soap is 50-100 g, preferably 70-90 g (the error is controlled within 2 g).

The compactness of the soap body is as follows: 4-5 min: the soap body is compact and not loose and is not easy to break;

3-4 min: the soap body is loose and easy to break.

Watch 10

As can be seen from table 10, as the cold air drying time is prolonged, the dryness of the surface of the soap body becomes higher and higher, and the compactness of the soap body is excellent. In addition, as can be seen from table 10, the long cold air drying time reduces the moisture content in the soap body, which deteriorates the internal adhesion force, which is disadvantageous for adhesion and causes a slight decrease in the compactness of the soap body.

It can be seen from the examples and comparative examples of the invention and from the performance tests that:

when the SLS needle-like multi-effect active agent is mainly surface active and the content is more than 80 percent, the product has strong degreasing power, easy flushing and excellent anti-itching performance, but the pH value of the system is higher, the irritation is very large, the irritation of the system can not be reduced to an ideal value by compounding 2 percent of lauramidopropyl betaine, and the wet hair combing performance and the dry combing performance are poor;

when the SLS needle-shaped multi-effect active agent is below 80 percent, the SCI-85 of the cocoyl isethionate is above 10 percent, the compounded lauramidopropyl betaine has lower irritation than the compounded sodium lauryl amphoacetate, and when the lauramidopropyl betaine is above 1 percent and below 5 percent, particularly above 1.5 percent and below 3 percent, the flushability and anti-itching performance of the product system are superior to the compounded effect of the sodium lauryl amphoacetate, but the two performances are the same on wet hair combing performance and dry hair combing performance;

when the SLS needle-shaped multi-effect active agent is below 80 percent, fatty acid methyl ester sodium sulfonate MES replaces coconut oil-based hydroxyethyl sodium sulfonate SCI-85, the appearance of a product is influenced by the granularity of ground powder, the foaming power is reduced to a certain extent and the pH is higher than that of the coconut oil-based hydroxyethyl sodium sulfonate SCI-85 due to poor water solubility and low foaming surface activity of the fatty acid methyl ester sodium sulfonate MES, the degreasing power performance, the flushing easiness and the anti-itching performance are poor in the hair washing process, and the fatty acid methyl ester sodium sulfonate MES is easy to remain in hair roots to influence the scalp health;

when the content of the SLS needle-shaped multi-effect active agent is more than 40 percent and less than 80 percent, the content of the sodium cocoyl isethionate SCI-85 is more than 10 percent and less than 50 percent, and the content of the lauramidopropyl betaine is more than 1 percent and less than 5 percent, the foaming force and the foam stability of the system are optimal in 30s, and the foam is fine and difficult to break. When the lauramide propyl betaine content is less than 1%, the system has large foam and is easy to break; when the content of the lauramidopropyl betaine is more than 5 percent, the improvement of the foaming performance is not obvious, the foaming performance is influenced by the low-foaming surfactant with higher content, and the cost is correspondingly increased;

when the content of the SLS needle-shaped multi-effect active agent is more than 40 percent and less than 80 percent, and the content of the lauramidopropyl betaine is more than 1 percent and less than 5 percent, if the content of the sodium cocoyl isethionate SCI-85 is more than 50 percent, the foaming performance of the system is reduced, the irritation is reduced, but the degreasing power of the product is reduced and the anti-scalp itching performance is not outstanding;

the polyhydric alcohol moisturizing component is added into a product system, the combing performance of dry hair and wet hair of the system is improved, but the effect is not obvious, when the conditioner polyquaternium and the deep sea two-section camelina sativa seed oil are added, the combing performance is obviously improved, and the comprehensive effect of the product is better.
