Description

[0001] Hair Conditioning Composition [

The present invention relates to high functionality hair conditioning compositions. More particularly, the present invention relates to a silicone-based hair conditioning composition comprising water, an organic nonionic surfactant, a silicone surfactant, a polydimethylsiloxane gum and an antiseptic, and a method of making the same.

Modern human hair is damaged by excessive combing, dryness, frequent washing, exposure to ultraviolet rays, and external stimulation or chemical infiltration. Accordingly, there is an increasing demand for a conditioning agent having excellent glossiness and combability in order to prevent hair damage and to restore damaged hair.

2. Description of the Related Art [0002] In recent years, a product having two functions has been attracting attention in order to eliminate the inconvenience of separately using the shampoo and rinse and to save time. Emulsion compositions containing silicone have attracted particular attention as a possible means.

Silicone is a high molecular weight, low viscosity change with temperature change, excellent permeability to oxygen and carbon dioxide, and does not interfere with skin respiration. It gives continuous gloss and gloss when used on hair, It can be said that it is an optimum material as a raw material of

Silicone-containing hair conditioning emulsion compositions range from low viscosity to high viscosity, but compositions with high viscosity are excellent in terms of persistence and combing.

U.S. Pat. No. 4,726,945 discloses conditioning compositions comprising cationic surfactants, amidoamines, alkanols, cyclomethicone, and the like. However, the above-mentioned invention is a composition which does not use polymeric silicon, which is insufficient in the effect of imparting flexibility to hair.

Korean Patent Publication No. 2001-0036921 discloses a conditioning composition for hair containing a liquid crystal microemulsion base and an organosilicon polymer. Patent Application Publication No. 2003-0039304 discloses a technique for conditioning hair using a specific amino silicone, These techniques lack the effect of imparting the gloss and softness of the hair.

The present inventors have found that a hair conditioning composition comprising water, an organic nonionic surfactant, a silicone surfactant, a polydimethylsiloxane gum, and a preservative is superior in flexibility, gloss, Attention has been paid to the fact that not only the conditioning effect such as antistatic property but also the damaged hair recovery and hair protection performance are excellent.

A fundamental object of the present invention is to provide a hair conditioning composition comprising water, an organic nonionic surfactant, a silicone surfactant, a polydimethylsiloxane gum and a preservative.

Still another object of the present invention is to provide a method for preparing a silicone composition comprising: (i) mixing an organic nonionic surfactant, a silicone surfactant and a polydimethylsiloxane gum; And (ii) adding and stirring the mixture of step (i) with water and an antiseptic agent.

The basic object of the present invention described above can be achieved by providing a hair conditioning composition comprising water, an organic nonionic surfactant, a silicone surfactant, a polydimethylsiloxane gum and a preservative. The hair conditioning composition of the present invention is an emulsion.

The water contained in the hair conditioning composition of the present invention is preferably deionized water. The water may be suitably adjusted to the solids content required in the hair conditioning composition and is preferably 15 wt% to 30 wt% based on the total weight of the composition. If the content of water is out of the above range, the stability, viscosity, etc. required for the hair conditioning composition can not be achieved.

The organic nonionic surfactants included in the hair conditioning composition of the present invention include polyoxyethylene alkyl ethers, polyoxyethylene allyl alkyl ethers, polyoxyalkylene alkylphenol ethers, polyoxyalkylene aryl esters, polyoxyalkylene sorbic acid alkyl Ester, sodium lauryl ether sulfate or stearyltrimethyl ammonium chloride, but is not limited thereto.

The organic nonionic surfactant is preferably contained in an amount of 5 wt% to 13 wt% based on the total weight of the hair conditioning composition of the present invention. If the content is less than 5 wt%, it may not be formed well. If the content is more than 13 wt%, the conditioning effect (glossiness, coating property, etc.) of the resulting emulsion may be deteriorated.

The silicone surfactant included in the hair conditioning composition of the present invention serves as an emulsifier for the composition.

The silicone surfactant is preferably dimethicone copolyol. For example, Bis-PEG / PPG-25/25 dimethicone or Bis-PEG / PPG-30/20 dimethicone may be used as the silicone surfactant.

The silicone surfactant is preferably contained in an amount of 3 wt% to 10 wt% based on the total weight of the hair conditioning composition of the present invention. If the content of the silicone surfactant is less than 3 wt%, it may not be formed well. If the content of the surfactant is more than 20 wt%, the conditioning effect (gloss, coating property, etc.) of the resulting emulsion may be deteriorated.

Formula _{(CH 3) 3 SiO (Si} (CH 3) 2 O) n Si (CH 3) polydimethylsiloxane of ₃ will have its viscosity changes according to the polymerization degree (n). As the degree of polymerization of the polydimethylsiloxane increases, the viscosity increases.

When the viscosity of polydimethylsiloxane is 5 cSt or less, it is volatile. The viscosity of the polydimethylsiloxane is in the range of 5 cSt to 1,000,000 cSt and is referred to herein as a silicone fluid or a silicone oil. When the viscosity of the polydimethylsiloxane is 1,000,000 cSt or more, it is referred to as silicon gum.

The polydimethylsiloxane gum in the present invention refers to a polydimethylsiloxane having a viscosity of 1,000,000 cSt or more and no cross-linking.

A preferred amount of polydimethylsiloxane gum comprised in the hair conditioning composition of the present invention is 50 wt% to 60 wt%, based on the total weight of the composition. If the content of the polydimethylsiloxane gum is less than 50 wt%, the viscosity of the composition may be lowered, thereby decreasing the stability of the composition and reducing the hair conditioning effect. When the content of the polydimethylsiloxane gum exceeds 60 wt%, the stability is lowered and the polydimethylsiloxane gum is not well dispersed in the composition.

The weight average molecular weight of the polydimethylsiloxane contained in the hair conditioning composition of the present invention is preferably from about 60,000 to 500,000, more preferably from 100,000 to 500,000.

Due to the high viscosity of the polydimethylsiloxane gum, the application of polydimethylsiloxane gum to hair conditioning products provides excellent combing and residual properties and forms a film on the hair to form smooth, glazed hairs.

The preservative contained in the hair conditioning composition of the present invention enhances the storage stability of the product by inhibiting the microbial growth that can occur during the production process of the hair conditioning product and the long-term storage.

Preservatives known to those skilled in the art which are conventionally used in the production of silicone emulsions can be used as the preservatives. For example, Neolone 950 (ROHM AND HAAS), which is a cosmetic preservative whose main component is 2-methyl-4-isothiazolin-3-one (MIT), can be used.

A preferred amount of polydimethylsiloxane gum comprised in the hair conditioning composition of the present invention is 50 wt% to 60 wt%, based on the total weight of the composition.

Still another object of the present invention described above is to provide a method for producing a silicone composition, which comprises (i) mixing an organic nonionic surfactant, a silicone surfactant and a polydimethylsiloxane gum; And (ii) adding and stirring the mixture of step (i) with water and an antiseptic agent.

When water is added in step (ii), water may be added in two portions. At this time, 4 wt% to 8 wt% of water is firstly introduced first, and 12 wt% to 16 wt% of water is firstly introduced. The reason why the water is added in two portions in this way is to control the size of the emulsion to be produced.

The size of the emulsion produced when the water is added in two portions to the water is smaller than the size of the emulsion produced when the water is added at once.

The composition produced by the hair conditioning composition manufacturing method of the present invention comprises 15 wt% to 20 wt% of water, 5 wt% to 13 wt% of an organic nonionic surfactant, 3 wt% to 10 wt% of a silicone surfactant, , 50 wt% to 60 wt% of polydimethylsiloxane gum, and 0.001 wt% to 10 wt% of preservative.

The organic nonionic surfactant used in the method of preparing the hair conditioning composition of the present invention is selected from the group consisting of polyoxyethylene alkyl ether, polyoxyethylene allyl alkyl ether, polyoxyalkylene alkyl phenol ether, polyoxyalkylene aryl ester, polyoxyalkylene sor A diacyl alkyl ester, sodium lauryl ether sulfate or stearyltrimethyl ammonium chloride.

The silicone surfactant used in the method of making a hair conditioning composition of the present invention may be a dimethicone polyol.

The molecular weight of the polydimethylsiloxane gum used in the hair conditioning composition preparation method of the present invention is preferably 60,000 to 500,000.

The preservative used in the hair conditioning composition preparation method of the present invention is preferably a preservative containing 2-methyl-4-isothiazolin-3-one as a main component.

The hair conditioning composition of the present invention is excellent in conditioning effects such as flexibility, gloss, coatability, and antistatic property to hair, and is excellent in damaged hair recovery and hair protection performance.
