Conditioning Shampoo Composition

The present invention relates to a conditioning shampoo composition, and more specifically, to maintain the foaming function and cleaning power, which is the basic function of the shampoo, but excellent foam retention power, the feeling of air bubbles and soft, wet and dry hair, such as combing, softness and conditioning effects In particular, the present invention relates to a conditioning shampoo composition having an excellent conditioning effect on damaged hair.

Since the shampoo for removing hair contamination is mainly composed of anionic surfactants, it is easy to lose hair flexibility and gloss as it removes not only the contamination of the hair but also the oil protecting the surface of the hair. In order to compensate for this, researches have been conducted on the shampoo composition which gives both the cleaning effect and the conditioning effect to the hair, and the shampoo composition which gives the hair cleaning and conditioning effect to the hair is commercialized with only one use of the shampoo.

The conditioning effect of hair is provided primarily through the use of cationic surfactants, hydrocarbon oils, silicones and the like. Korean Patent No. 10-0743829 mentions that cationic surfactants with glyceryl groups can be introduced to solve complexes with anionic surfactants while promoting coacervate formation to provide excellent conditioning, but hair with severe chemical damage Insufficient conditioning effect.

U.S. Pat.Nos. 5,853,707, 6,706,258, 5,246,694 and the like mention that silicone emulsions can be applied with cationic polymers to form coacervates to provide good conditioning. Specifically, these documents suggest cationic cellulose polymers and specific silicone emulsions, specific cationic guar polymers and silicone emulsions, and cationic polymers and silicone emulsions and ester-based emulsions to maximize these effects. These are also severely damaged hair lacks the conditioning effect, there is a problem that the deterioration of foaming occurs.

U.S. Patent No. 5,932,202 discloses the use of cationic cellulose polymers and conditioning agents such as silicones in combination with ethoxylated alkyl sulfate surfactants to improve the conditioning of shampoos, thereby reducing the foaming forces caused by increasing the amount of conditioning agents. It is said that it can provide improved conditioning while reducing unsatisfactory side effects, but it is lacking in severely damaged hair.

In addition, recently published Korean Patent Publication No. 2010-0024136 states that when using guar hydroxypropyltrimonium chloride and polyquaternium-10 together with a specific anionic surfactant, excellent feeling and conditioning can be obtained. However, the combination of the above alone also lacks the conditioning effect in severely damaged hair.

In order to solve these problems, the present inventors have studied various combinations of conditioning raw materials, and while using a cationic cellulose polymer and a cationic guar polymer together, additionally using a low molecular weight dimethicone emulsion, the conditioning performance is maximized. Discovered to complete the present invention.

According to one embodiment of the invention, the surfactant portion may be included in 6 to 50 parts by weight based on 100 parts by weight of the total composition. If it is included in less than 6 parts by weight, the cleaning power is reduced and the amount of foaming is reduced, and if it is included in more than 50 parts by weight may cause hair to tangled and stiff, which may cause hair damage.

The conditioning shampoo composition of the present invention uses a cationic cellulose polymer and a cationic guar polymer together to obtain a conditioning effect.

When shampooing wet hair is generally negatively charged, the use of positively charged cationic polymers allows the hair to be adsorbed by different charges to protect the hair. The cationic polymer not only exerts a conditioning effect by adsorbing the hair itself, but also induces hair adsorption of silicon to improve the conditioning of the hair, and this effect is further enhanced when two cationic polymers are used together.

In particular, when the weight ratio of the cationic cellulose polymer and the guar polymer is in the range of 5: 1 to 1: 5, the softening of the conditioning effect and the feeling of use is maximized, and the effect is halved when out of this range.

The cationic cellulose polymer is a conditioning agent, generally called polyquaternium. The cationic cellulose polymer is a reaction product of an epoxide substituted with trimethylammonium and a quaternary ammonium salt polymerized with hydroxyethyl cellulose, thereby improving the hair adsorption of silicon. To provide. Cationic cellulose polymers include a variety of polyquaternium series but the cationic cellulose polymers suitable for the present invention are polyquaternium-10.

As polyquaternium-10, products of Amerchol's Polymer LR, JR, JP, KG series are generally used, but not limited thereto.

Guar hydroxypropyltrimonium chloride or hydroxypropyl guar hydroxypropyltrimonium chloride may be used as the cationic guar polymer.

According to one embodiment of the present invention, the cationic cellulose polymer and the cationic guar polymer may be included in an amount of 0.01 to 2 parts by weight, preferably 0.1 to 2 parts by weight, based on 100 parts by weight of the total composition. If the amount is less than 0.01 parts by weight, the improvement in conditioning is insignificant, and when added in an amount of 2 parts by weight or more, build-up may occur.

In addition, the shampoo composition of the present invention includes a specific range of silicone.

The silicone is used to enhance the conditioning effect, and in the present invention, a relatively low viscosity silicone was selected and used. This is because the use of two cationic polymers can lead to build up or impaired feeling due to excessive conditioning when high viscosity silicones are used.

In the present invention, a silicon having a stock solution viscosity of 50,000 to 1,000,000 cst at 25 ° C is used. Conditioning effect is insignificant when silicon below the above range is used, and when the silicon exceeding the above range is used, buildup may occur due to excessive conditioning or rather, the usability may be degraded.

According to an embodiment of the present invention, the silicone may be included in an amount of 0.1 to 5 parts by weight based on 100 parts by weight of the total composition. When included in less than 0.1 part by weight can not exert sufficient conditioning effect, when exceeding 5 parts by weight may be a problem in the formation of the formulation, the amount of foaming may be reduced, build-up may occur due to excessive conditioning.

The shampoo composition of the present invention may further comprise a single or a mixture thereof selected from the group consisting of fatty alcohols and cationic surfactants in order to enhance the conditioning effect.

The composition of the present invention may further include ingredients commonly used in the manufacture of hair cosmetics, such as moisturizers, wetting substances, fragrances, preservatives, vitamins, proteins and the like. Specifically, Preservative such as paraoxybenzoic acid ester; Humectants, such as carboxy vinyl polymers; Hair repair agents such as hydrolyzed wheat protein; And viscosity modifiers such as sodium chloride, ammonium chloride and the like can be used within the ordinary knowledge of those skilled in the art.
