Description

Conditioning Shampoo Composition

The present invention relates to a conditioning shampoo composition. More specifically, it solves the problem of hair lifting or sinking when used alone or in combination with an existing hair dressing agent, and solves the problem of drying hair after drying caused by the use of dimethicone / vinyl dimethicone crosspolymer. It is related with the conditioning shampoo composition which improved the hair-setting effect, such as and smoothness.

Shampoos have used various forms of silicone or derivatives thereof to impart conditioning efficacy. Silicones may be classified into low viscosity silicones (silicon oils) and high viscosity silicones (silicone gums) according to the degree of polymerization of water-soluble and water-insoluble silicones, volatile and nonvolatile silicones, or molecules.

Water-soluble silicones are limited to use due to various disadvantages such as discoloration and odor when applied to hair products such as shampoos.Fragrance Journal, 1997, No.10, p.99-102 Although most used, it is difficult to secure product stability when applied to products.

In order to compensate for these disadvantages, silicone (Dow Corning) made of an emulsion, such as Korean Patent No. 194-25101, may be used, and the polymer may be stabilized in a product by using a polymer material as a stabilizer, such as US Patent No. 4,788,006. It was.

In addition, water-insoluble silicone reduces the friction and reduces static electricity.However, due to the silicone's unique water repellency, the use of silicone-containing shampoo has the disadvantage of severely causing the hair to fly out due to static electricity. In addition, there is a problem that build-up occurs as a large amount is used to give a softness.

It is common to use silicones and other hair-styling agents together to eliminate the drawbacks such as fly-away and build-up.

Thus, much research has been done on the mixing of silicone and other hair dressing agents, including cationic polymers (WO 9210162, WO 9210163), quaternary ammonium or amines with three long chain alkyl groups (UP 4704271; P & G), long chain acyl Derivatives or amine oxides (EP 0312234), conditioning agents containing quaternized nitrogens with two long-chain alkyl groups (UP 5034218), cationic silicones and aminoaliphatic heteropolysaccharides (GB 2164558) I may use it.

In addition, when silicone, cationic polymer and oil phase hair dressing agent are used together (WO 9308787), when the diallyldialkylammonium salt polymer is selected and used among silicone and cationic polymer, and oil phase hair dressing agent is used together (Japanese Patent Laid-Open) 7-53340).

However, the mixed use of silicone and the hair dressing agent is a problem that the disadvantages such as fly-away phenomenon and build-up are somewhat resolved, but softness slightly falls and the hair sinks heavily.

In this regard, U. S. Patent No. 5871761 describes various applications of skin and hair cosmetics of dimethicone / vinyl dimethicone crosspolymer in water base.

Dimethicone / Vinyl Dimethicone Crosspolymer is also called Dimethyl Polysiloxane Elastomer Powder, Elastomer Powder, Crosslinked Elastomer Silicone, etc., and it is a white powder with vinyl (Vinyl) cross-linked to Dimethicone Polymer. It is used by dispersing in aqueous surfactant solution. It has excellent absorption power against oil and sebum, excellent softness in dry state, no stickiness or oily feeling and gives a light smooth texture.

However, the use of dimethicone / vinyl dimethicone crosspolymer according to the patent alone or mixed with dimethicone has a problem in that the softness is good during the drying process after using the product, but the hair feels dry and crumbly after being completely dried.

Therefore, the present inventors can supplement the disadvantages of the use of silicone alone and increase the conditioning effect according to the mixed use of the existing hair dressing agent and the silicone, and study the invention that improves the disadvantages of the dimethicone / vinyl dimethicone crosspolymer. It was completed.

In order to solve the above problems, the present invention provides a conditioning shampoo composition containing a dimethicone / vinyl dimethicone crosspolymer, a dialkyl dimethyl ammonium salt, and a high viscosity dimethicone at the same time to improve the hair-setting effect such as softness and smoothness It aims to do it.

The above and other objects of the present invention can be achieved by the present invention described below.

The present invention to achieve the above object,

A shampoo composition containing a dimethicone / vinyl dimethicone crosspolymer,

It provides a conditioning shampoo composition comprising a dialkylmethylammonium salt and a high viscosity dimethicone.

At this time, when the dimethicone / vinyl dimethicone crosspolymer is used at 0.01% by weight or less, the hairdressing effect on the hair is insufficient, and when used at 20% by weight or more, the effect is increased, but the amount of adsorption on the hair and the scalp is too high. Rather, side effects such as itching are concerned.

Dialkyl dimethylammonium salt is represented by the following general formula,

_{[(R) 2 -N (CH} 3) 2] + X -

Wherein R is a straight or branched chain alkyl group having 8 to 22 carbon atoms and an alkenyl group or a hydroxyalkyl group having 8 to 22 carbon atoms, and X represents a halogen atom or an alkyl sulfate group having 1 to 2 carbon atoms.

Typical examples of the compound of the general formula include dicetyldimethylammonium chloride, distearyldimethylammonium chloride and the like, and 0.01 to 10% by weight, preferably 0.1 to 5% by weight is used.

High viscosity dimethicone is used in the viscosity of 10000cs to 50 millioncs (gum) 0.01 to 10% by weight, preferably 0.1 to 5% by weight.

High viscosity dimethicone was used to fall within the range of 0.01 to 10% by weight, but when used below 0.01% by weight, the hairdressing effect is insufficient, and when it is used by more than 10% by weight, the amount of adsorption on the hair and the scalp is too high. do.

In addition, 1 to 50% by weight of anionic and zwitterionic surfactants are used, and other hair conditioning agents, colorants, flavors, thickeners, preservatives, pH adjusters, water and the like are used.

On the other hand, the surfactant used in the present invention may be used alone or in combination of anionic surfactant and zwitterionic surfactant, and 5 to 30% by weight, preferably 10 to 25% by weight, respectively, as the selected surfactant.

As the anionic surfactant used in the present invention, sodium lauryl sulfate, lauryl ammonium sulfate, lauryl magnesium sulfate, lauryl triethanolamine, sodium polyoxyethylene lauryl sulfate, polyoxyethylene lauryl sulfate, ammonium and the like are used.
