Description

Conditioning shampoo composition

More particularly, the present invention relates to a conditioning shampoo composition which is stable in transparency and excellent in washing power and foaming power, which is a function of the shampoo, has excellent conditioning effect, and is less irritating to the skin or scalp .

Shampoo, a hair cleanser, cleanses hair by removing contaminants and sebum from the hair and scalp, but shampooing removes moisture and sebum from the sebum and hair to weaken the softness of the hair and dry it, making hair tangled and difficult to handle. In addition, rarely, the stimulation by the surfactant or the conditioning agent contained in the shampoo may cause keratin, dandruff and inflammation.

Sulfate-based surfactants, which are frequently used as human body cleansers, are a common industry opinion that recent changes in environmental pollution and lifestyle have caused a lot of sensitive scalp to cause irritation to such consumers.

Beta man, one of the amphoteric surfactants, has been widely used since 1970 to improve the amount of foam and adjust the physical properties of shampoo, bath foam, liquid soap and so on since it has low possibility of stimulation. However, the term "Clinics in Dermatology" (1996; 14: 67-76, 1997; 15: 485-491), Journal of American Academy of Dermatology (vol.27, number 6, part 1, (1986), and the American Journal of Contact Dermatitis (vol. 12, issue 4, December, 2001, p. 232-224) Similar symptoms have been reported after cocamidopropyl betaine. In addition, the Journal of the American Academy of Dermatology (vol. 60, number 1, January, 2009) reports the case of 1% allergic reaction by cocamidopropyl betaine.

In order to supplement the conditioning effect of the shampoo, a general opaque shampoo includes a hair conditioning agent to increase the flexibility of the hair. However, in the case of the transparent shampoo, when the conventional hair conditioning agents are used, the formulation becomes opaque and the conditioning components to be added are limited. In addition, the hair conditioning agent may remain on the scalp and cause irritation.

U.S. Patent No. 5,514,369 suggests a mild shampoo composition using an alkyl polyclicoside as a main surfactant. However, when alkylpolycoxide is used as the main ingredient, the amount of bubbles is insufficient and the conditioning effect is unsatisfactory. There is a shortage of weakened scalp. US patent application US2002 / 0173435 proposes a mild shampoo composition comprising a cocamidopolypropylene derivative, but it still lacks mild shampoo because it considers an increase in foaming power through cocamide betaine.

It is an object of the present invention to provide a conditioning shampoo composition which is excellent in cleaning power and foaming power, which is an inherent function of shampoo while maintaining transparency stably, has excellent conditioning effect, and is less irritating to the skin or scalp .

The cationic cellulosic polymer may be included in an amount of 0.05 to 0.5 parts by weight based on the total composition. If it is contained in an amount of less than 0.05 part by weight, it may be difficult to achieve the purpose of imparting a conditioning effect to the hair, and if it exceeds 0.5 part by weight, build up may occur in the long term use.

The cationic cellulose polymer may be any of those known in the art without limitation. Polyquaternium-10 is preferably used.

The cationic cellulose polymer may have a nitrogen content of 0.5 to 1.1% by mass based on the total mass of the cationic cellulose polymer. By using a polymer having a lower nitrogen content than the conventional cationic cerulose polymer, it is possible to reduce the amount of the conditioning component adsorbed on the hair, thereby reducing the build-up phenomenon occurring during long-term use and reducing the adsorption of the nitrogen component, .

The cationic cellulose polymer may be one having an aqueous solution of 1% aqueous solution of the polymer having a viscosity of 1000 to 2500 cPs. When a cationic polymer having a viscosity in the above range is used, the conditioning effect is increased at the time of rinsing.

< Experimental Example  1> Consumer Feeling  evaluation

In order to evaluate the feeling and conditioning effect of the transparent conditioning shampoo prepared in Examples 1 to 5 and Comparative Examples 1 to 5 and Comparative Example 8, 330 women aged 40 years were selected and tested for the evaluation items shown in Table 3 below for 1 month. The lowest score was 1 point and the highest score was 5 points. The test results are shown in Table 3 below.

According to the above Table 3, the conditioning shampoo composition of the Example was rich in bubbles and had a good feeling of bubbles when used, and was excellent in terms of conditioning in shampooing because hair was not entangled. In addition, it did not become itchy, and dandruff and rash decreased, and it was hypothetical. On the other hand, the shampoo composition of Comparative Example 1 had a low content of surfactant as a whole and decreased the amount of bubbles and detergency. The composition of Comparative Example 2 increased the detergency due to an increase in anionic surfactant content. However, . The composition of Comparative Example 5, which contained polyquaternium-10 in an excess amount, was not evaluated as a whole and was evaluated as being negative in terms of softness. Thus, the excessive content of the conditioning agent negatively affects the feeling of use as well as the mildness Could know. In addition, the composition of Comparative Example 8 using a low viscosity of the cationic cellulose had a worse conditioning effect than that of the Example in rinsing. Overall, the compositions of the comparative examples were rated worse than the shampoo compositions of the examples in feeling.

< Experimental Example  2> Evaluation of irritation

MTT assays were performed to evaluate the irritation of the shampoos prepared in Examples 1 to 4 and Comparative Examples 6 and 7. The MTT assay is a cell growth test that tests the growth rate of a diluted shampoo and evaluates its toxicity. Based on the cell growth rate of 50% (IC ₅₀ value), a product with a higher concentration may have a lower irritation degree. The test results are shown in Table 4 below.

According to the above Table 4, the shampoo composition of the comparative example as compared with the shampoo composition of the examples showed an IC ₅₀ concentration, and the composition of the examples is hypoallergenic.

< Experimental Example  3> Evaluation of transparency

The turbidity of the transparent shampoo prepared in Examples 1 to 9 was measured to evaluate transparency. The turbidimeter is Hach 2100N Laboratory Turbidimeter and can be considered transparent if the turbidity is below 100 NTU. The turbidity measurement results are reported in Table 5 below.

According to Table 5, all of the shampoo compositions of the present invention were found to be transparent, and transparency was stably maintained to give a beautiful appearance.

As described above, the conditioning shampoo composition of the present invention is excellent in the cleaning power and bubble power, which are functions inherent in shampoo, and provides softness in rinsing and flexibility in hair, A hypoallergenic conditioning shampoo with less irritation to the skin and scalp.
