Description

Cationic Polymer Surfactant and Composition Comprising the Same {Cationic Polymer Surfactant and Composition Comprising the Same}

The present invention relates to a cationic polymer surfactant imparting a cationic group to the starch and starch decomposition products and a composition comprising the same, more specifically improved hair adhesion due to cationicity, conditioning effect by alkyl groups, starch-based polymer It relates to a hair cosmetic composition exhibiting hypoallergenic properties.

Modern people's hair is contaminated by exposure to ultraviolet rays, contact with the surrounding environment such as dust, sebum secreted from the hair follicles, and frequent perms, hair dry, dyeing, combing and the like. Damaged hair, when wet or dry, is hard to handle and difficult to handle, such as hard, stiff, and poorly combed. Therefore, consumers' demands and preferences for conditioning products that improve the appearance and feel of hair and make them easier to handle are increasing day by day.

Conditioning shampoo is a product that has a cleaning effect that removes contamination from hair and scalp, and conditioning effect that makes damaged hair easy to handle, shiny and smooth. Thus, conditioning shampoo compositions have been used for the purpose of improving the texture and visual benefits of hair, such as softness, flexibility, shine, anti-static, combability, etc., with proper cleaning effect.

Hair shampoo cleanses hair by removing contaminants and sebum from hair and scalp. However, there is a disadvantage that hair becomes tangled and difficult to handle through the shampooing process. This is because shampoo removes sebum and hair moisturizing ingredients, so that the softness of the hair is weakened and dried. In order to compensate for this, a method for increasing the flexibility of hair by incorporating a hair conditioning agent into shampoo has been studied, but it is unsatisfactory for various reasons.

Conditioning effects on hair are provided primarily through the use of cationic surfactants and hair conditioning agents such as polymers, silicone conditioning agents, hydrocarbon oils and fatty alcohols.

Cationic surfactants and polymers, hydrocarbon oils and fatty alcohols are known to provide softness to hair and prevent static electricity, but have the disadvantage of inhibiting bubbles by forming complexes with anionic surfactants used for cleaning. In order to improve this, Korean Patent Laid-Open Publication 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. However, there is still a shortage in hair with severe chemical damage.

Non-volatile silicone oils and polymer silicone gums commonly used in hair conditioning agents provide gloss and flexibility to the hair and provide softness to the hair after drying, while lacking moisturizing properties and poor compatibility with other ingredients. Due to its properties, its utilization is limited, and when it is used repeatedly for a long time, it accumulates on the hair, which decreases softness and accelerates recontamination by dust and sebum (Personal Care, 2005.11., P.41 ~ 43). In addition, the silicone oil acts as an antifoaming agent such as oil in the shampoo composition to significantly lower the cleaning ability of the anionic surfactant (US Pat. Nos. 2,826,551, 3,964,500, 4,364,837). To improve this, US Pat. No. 4,741,855 states that while using anionic surfactants, while maintaining excellent washing performance, it can provide the hair with the benefits of excellent conditioning, but is still lacking in hair with severe chemical damage.

In order to solve the problem of silicones, Japanese Patent Publications H6-17097 and H7-11287 mention that polyhydric ions, anionic surfactants, amino acid surfactants and anionic surfactants can provide conditioning benefits. However, the increase in the conditioning effect by a simple combination of surfactants is also insufficient in hair with severe chemical damage. U.S. Patent No. 6,284,230 mentions certain anionic surfactants that can enhance the conditioning effect by forming coacervates through polyvalent metal ions and amino acid surfactants. There is a drawback to accumulation in the hair when used.

In addition, US Pat. No. 6,627,184 refers to a technique that further improves hair conditioning after wet and drying by applying a polyalphaolefin conditioning oil and a cationic polymer. .

Despite these efforts to select an appropriate combination of detergency and conditioning effect, it is desirable to provide a more improved hair conditioning shampoo composition. For example, it is desirable to improve the overall conditioning effect while maintaining the cleaning effect, which is the basic performance of the shampoo formulation, and the rich sponge. Increasing the amount of conditioning agent simply causes side effects such as greasy hair feeling, accumulation in hair during repeated use, and deteriorates the function of cleaning surfactant to remove hair contamination.

Therefore, there is a further need for a shampoo composition which can contain a conditioning agent, while at the same time maintaining the detergency without reducing bubbles in the shampoo, thereby achieving a further improved conditioning effect.

As a result of various studies in this background, it was found that the addition of cationic substituted starch and sugar derivatives to the conditioning shampoo composition has an excellent conditioning effect and bubble stabilization effect. Cationic polymer of the present invention is excellent in the adhesion and conditioning effect of the hair by replacing a long cationic alkyl group with starch and oligosaccharides. Through this, it is possible to propose a conditioning shampoo composition having excellent air conditioning and cleaning ability and excellent conditioning effect.

Evaluation item Example 3 Example 6 Example 12 Comparative Example 1 Comparative Example 2 Comparative Example 4 Glossiness in dry condition 3.9 4.2 4.6 3.1 3.3 3.4

According to Table 11, the shampoo of Example 3, the rinse of Example 6 and the essence of Example 12 containing a cationic polymer surfactant showed excellent glossiness compared to the comparative example.

As described above, the hair conditioning composition comprising the cationic polymer surfactant of the present invention is excellent in the effect of imparting gloss and softness to hair and sustaining conditioning, and thus can be used to impart conditioning effects to various hair cosmetic compositions. It does not show any buildup phenomenon even after long use.
