Definitions
- This application relates to laundry compositions.
- This application relates to the use of oxidized humic acid, its salts its derivatives and mixtures thereof in laundry compositions.
- This application relates to the laundry compositions ,whereas oxidized humic ,its salts its derivatives and mixtures thereof is added to the laundry composition in situ after synthesis or after separation of oxidized humic acid from reaction mixture.
- This application relates to the synthesis of oxidized humic acid which is compatible for the use in laundry compositions.
- oxidized humic acid oxidized humic acid , its salts, its derivatives and mixtures thereof.
- Detergents are surfactants with cleaning properties in dilute solutions.
- Detergents are ions or molecules that contain both polar and nonpolar components. The polar end allows the detergent to dissolve in the water, whereas the nonpolar end solubilizes hydrophobic materials which are main target of the cleaning process.
- Surfactant is the most important part of any cleaning composition. In general they are chemicals that, when dissolved in water or another solvent they orient themselves at the boundary between the liquid and a solid. Long nonpolar chain part of the surfactant molecule is attracted to oil, grease and dirt which are hydrophobic nature and another part of the molecule is attracted to water. Surfactant surround dirt until it is dislodged from the boundary.
- chelating agents used in cleaning compositions are phosphates, ethylene diamine tetra acetic acid (EDTA),its alkaline metal salts, citrate salts and zeolit.
- phosphates are about to be banned due to environmental concerns.
- Zeolit and citrate are not strong enough complexating agent and are used in excess amounts.
- EDTA have been developed as phosphate substitue. However its high price and limitation due to health concerns raise question of their replacement. Builders are often a good alternatives to said complexation agents.
- Builders are added to a cleaning composition to enhance efficiency of surfactants. They have a number of functions including softening, buffering, emulsifying and removing multivalent cations from water. Builders provide a desirable level of alkalinity which aids in cleaning. Builders help emulsify oily or greasy soil by breaking them up to tiny globules and keep them from settling back on the cleaned surface.
- Humic acid is a principal component of humic substances, which are the major organic constituents of soil, peat and coal. It is produced by biodegradation of dead organic matter. It is not a single acid; rather, it is a complex mixture of many different acids containing carboxyl and phenolate groups, so that the mixture behaves dibasic or tribasic functionally.
- a typical humic substance is a mixture of many molecules having aromatic, phenolic, carboxylic substituents linked together.
- humic acid having a variety of components including phenol, quinone, catechol and sugar moieties:
- Oxidized humic acid which is the subject matter of the present invention has differencies as some bonds are disrupted and some functionalities are oxidized. Oxidized humic acid has generally smaller molecular weight and increased number of hydroxy and carboxyl groups.
- Oxidized humid acid compounds are used in the technic as fertilizer, regeneration of polluted grounds, animal breeding and water regeneration mainly.
- the present invention relates to a new use of oxidized humic acid.
- the present inventor has discovered that by adding oxidized humic acid compounds to the laundry compositions foaming and cleaning capacity has increased.
- oxidized humic acid is not used in laundry compositions. There exist no commercially available laundry composition product containing oxidized humic acid on the market.
- oxidized humic acid Due to the complex mixture character of humic acid and consequently complex mixture character of oxidized humic acid in the text the synonym "oxidized humic acid” will be standing for "oxidized humic acid , its salts, its derivatives and mixtures thereof". Further the same synonym will be standing for compounds of oxidized humic acid and its salts and mixtures which is derivatized afterwards and derivatized humic acid which is oxidized afterwards and its salts and mixtures thereof.
- oxidized humic acid may be in form of its salts. Due to the presence of carboxylic acids in the structure salts may be cationic character of any type.
- humic acid The presence of carboxylate and phenolate groups give humic acid the ability to form complexes with ions such as Mg2+, Ca2+, Fe2+, Fe3+. This capability is enhanced by oxidation of humic acid.
- oxidized humic acid In the past no complex binding capability of oxidized humic acid is measured.
- the present inventor additionally measured metal ion binding capacity and found that oxidized humic acid is an excellent builder with high earth alkaline metal cation capturing capability.
- oxidized humic acids is by far superior to classic builder such as polyphosphate and even superior to the new generation builders which are of acrylic acid copolymer nature.
- Oxidized humic acid with 1350mg Ca ion binding capacity per gram has stronger complexation capability than any other commercially available builder currently as shown herewith below.
- Calcium ion binding capacity in mg with respect to per gram builder used in aqueous solutions is measured titrimetrically.
- the ideal builder should have strong earth alkaline metal cation capturing capacity, should be of organic origin and ecologically acceptable.
- the present inventor unexpectedly found that humic acid in oxidized form is an excellent builder with high earth alkaline metal cation capturing capability. Furthermore oxidized humic acid has not such ecologically nature originated drawbacks since it is of organic origin and decompose naturally in the natural environment.
- Oxidized humic acid serve due to its complex organic structure as emulsifying agent, as a base for buffering purposes and furthermore as complexation agent. All these properties summed establish oxidized humic acid as a good builder.
- compositions disclosed in the present invention have improved foaming thus cleaning properties due to high builder capabilities of oxidized humic acid used.
- Builders in detergent industry are compounds capable of capturing earth alkaline metal cations which are specific for the hardness of water. Surfactants which are the main component of cleaners cannot reveal their full cleaning capabilities in presence of those cations. Oxidized humic acid is more prone to capture Mg2+ and Ca2+ cations than commercially already used builders. It is a good working, organic, with less ecological concern builder compound thus superior to already existing builders.
- Humic acid is originated from wood decomposition products. It is a renewable source and existing in large scale. Considering additionally its organic nature humic acid is an ideal compound as builder from economical and environmental aspect both.
- carboxylate and phenolate groups give humic acid the ability to form complexes with ions such as Mg2+, Ca2+, Fe2+, Fe3+.
- oxidized humic acid is superior to the humic acid as builder.
- the present inventor assume that additional oxidized phenol and carboxylate groups formed during oxidation procedure enhance the complexation capability. Measurements of the present inventor reveal that humic acid in oxidized form has higher earth alkaline metal cation complexation capability hence is a better builder. In comparative washing tests achieved results support this fact as well. With oxidized humic acid replaced cleaning compositions are at least as good as classic builder containing laundry compositions regarding cleaning capabilities. We assume that oxidized humic acid has relatively more phenolate, carboxylate groups which are participating by complexation process.
- Humic acid is a deep black colored substance due to high content of pigments which makes it non desirable to use in cleaning compositions. This fact may be the reason for not using humic acid and staying away from its derivatives in field of cleaning compositions. Applying excess amount of oxidizing agent by synthesis of oxidized humic acid convert much of the pigments to noncolored substances. Oxidized humic acid obtained as such is light colored enough to be able to used for cleaning purposes. This color issue is an additional reason beside having higher complexation capacity for giving preference to oxidized humic acid and not to humic acid in the present invention.
- Builders are compounds having the capability to capture the multivalent metal cations from water and remove them from the cleaning or washing medium. In the absence of these cations ,surfactants, which are the main active washing agents, are not captured from these cations and can reveal their complete washing strength.
- Builders have multiple anionic functional groups which are capable to bind by complexation earth alkaline metal cations.
- First commercially used builders were polyphosphates which are stil in use. They were able to capture multivalent metal cations and remove it from the medium by precipitating, since phosphate salts of these metal cations are less soluble in water. But due to environmental concerns related to overfertilizing water with phosphate and consuming of oxygen by water plants, which affect the life in water, polyphosphate builder are needed to be replaced with alternative builders. Existing alternatives are of polyacrylate nature which are again suspect of being hazardous due to their synthetic nature. Especially unreacted monomer residues remaining in polymers are main concern .
- a laundry composition comprising oxidized humic acid, its salts and derivatives and their mixtures.
- Oxidized humic acid used in laundry compositions in the present invention are stable in nature. They maintain their builder properties in ambient conditions for a long time and at considerable harsh conditions for reasonable time period in comparison to the existing commercially available cleaning products. Oxidized humic acid containing laundry compositions have same performance, durability, foaming capacity, cleaning capacity and stability compared to the equivalents in the marketed products. The oxidized humic acid containing compositions of the present invention are equal or superior to the commercially available laundry composition products.
- oxidized humic acid amounts by weight are by far less than the existing commercially available composition products due to superior builder capacity. This makes its use more economical and with less environmental concern. Due to its stable nature oxidized humic acid can be used in liquid laundry compositions of the present invention as well and last without degradation or negative effects for adequate time period.
- oxidized humic acid is used in compositions for cleaning fabrics, clothes, carpets, woven or nonwoven type of textile any art.

- Oxidized humic acid FTIR spectrums reveal in comparison to humic acid increased number of aliphatic hydrogen, phenolic groups and carbonyl moieties at respective wavelengths. This is indicating the cleavage and oxidation of bonds of humic acid and increase in carboxylic acid groups content.
- oxidized humic acid is typically used in the form of aqueous solutions. As such it can be added to the liquid compositions directly from synthesis mixture without any treatment. As such oxidized humic acid containing reaction mixtures can be added directly to solid compositions for granulating purposes to obtain solid compositions.
- said oxidized humic acid is used in solid form such as powder or granule.

- Such compositions has no drawbacks with potential hydrogen peroxide residues. It is assumed that during the oxidation reaction all hydrogen peroxide is consumed and converted to percarboxylic acid residues of the oxidized humic acid compounds. Remaining hydrogen peroxide is decomposed. As such this way of introduction of oxidized humic acid is convenient, feasable and economically advantageous.
- Both in application in liquid form laundry compositions and solid form laundry compositions Application to the liquid composition is very convenient due to being same physical state. Application to the solid composition is advantageously as being granulation solvent as well.
