Description

Shampoo composition {SHAMPOO COMPOSITION}

The present invention can prevent "entanglement at the time of shaving" of hair damaged by coloring, perming, repetition of excessive drying of the dryer, and eliminating "burnt after drying", and at the same time, To a shampoo composition which can be reduced.

In recent years, there are increasing numbers of women who are subjected to chemical treatments such as coloring and perms. Therefore, the hair is damaged, and in particular, in wet hair, the hair tends to be entangled with each other, the broken hair, And it is worried about " bustiness of hair after drying ". In addition, skin irritation is damaged by external stimuli such as drying, ultraviolet ray, and coloring, and it feels "itching of saliva".

As a means for solving such incompatibility, a shampoo composition containing a rinsing component, such as a cationic surfactant or a high-quality alcohol, can adsorb a liquid crystal (liquid crystal) structure on the hair when rinsing the hair to exhibit smoothness, Various techniques have been proposed to suppress the occurrence of buzzing and give a smooth texture.

As such a shampoo composition, for example, a liquid crystal dispersing detergent composition comprising a cationic surfactant, a higher alcohol and a polyglycerin fatty acid ester (see Patent Document 1), a detergent composition such as an amphoteric surfactant, (See Patent Document 2), a silicone compound, a water-soluble liquid crystal structure, and a cleaning surfactant containing an amphoteric surfactant (see Patent Document 3) and the like have been proposed have.

However, in the above prior art documents, antiseptics (parabens, benzoic acid or its salts and the like) are mixed in order to obtain long-term storage stability of the preparation. Therefore, stimulation is too strong for people with weak skin or dry skin , Skin troubles such as contact dermatitis and allergies are known (see Non-Patent Document 1). In addition, the effect of preventing " entanglement at the time of shaving " of hair damaged by coloring, perming, and excessive drying of the hair dryer is solved, and the effect of reducing the " However, it is in the current state that further improvement and development are demanded.

The shampoo compositions of Examples 1 to 24 and Comparative Examples 1 to 8 were prepared according to a routine method according to the composition (unit: mass%) shown in Table 1. More specifically, water-soluble components containing components (C), (D) and (E) as required were mixed and dissolved in a water bath at 80 ° C to prepare an aqueous phase. To this aqueous phase, the oil phase containing the component (A) and the component (B) was added and mixed uniformly. Thereafter, the silicone emulsion was added and cooled to room temperature while stirring again. In addition, the pH was adjusted using citric acid as a pH adjusting agent.

Each of the obtained shampoo compositions was diluted 10-fold with purified water and the pH was measured at 25 캜 using a pH meter (HM-30G, manufactured by Dongdaikake Co., Ltd.). The results are shown in Table 1.

<Sensory Evaluation>

Sensory evaluation was carried out as described below with respect to &quot; no entanglement of hair in wet hair &quot;, &quot; no burring of hair after drying &quot;, and &quot; no itching in skin. The results are shown in Table 1.

[Sensory evaluation method]

Coloring, and perms within 3 months, and when the hair is entangled at the time of the hair breaker, and after drying with the hair dryer, it feels the hairlessness of the hair, and the 30 people in their 30s and 40s who feel the itching of the skin , And each shampoo composition was used for 7 days and evaluated according to the following criteria.

[Evaluation standard]

◎: 27 people out of 30 who answered "good"

◎ to ○: Among the 30 respondents who answered that they were good, 24 to 26

○: Among the 30 respondents, 15 to 23

△: 5 to 14 out of 30 respondents

×: Less than 5 persons who answered well

In addition, in the above evaluation criteria, "goodness" means that "no entanglement of hair in wet hair", "no hairiness in hair after drying" and "no irritation to skin" it means.

&Lt; Evaluation method of long-term storage stability >

About 40 ml of each shampoo composition was filled in a 50 ml glass vial and preserved at 40 占 폚 for 6 months. The appearance of each shampoo composition was visually judged according to the following criteria. The results are shown in Table 1.

[Evaluation standard]

&Amp; cir &amp;: No change in appearance and separation is not recognized

○: The appearance is uneven in some hues, but separation is not recognized

?: Partially, separation is recognized

X: Separation is recognized

&Lt; Evaluation of flushing force of shampoo composition >

Escherichia coli NBRC3972 and Staphylococcus aureus NBRC13276 were used as the bacterium. All of these were obtained from the Agency for Product Assessment Technology (NITE), an independent administrative agency.

The fungi were Paecilomyces variotii (environmentally derived).

These microorganisms were each cultured in the most appropriate medium (medium), and a microbial suspension was prepared so as to be about 10 ⁸ to 10 ⁹ cells / ml.

To 20 g of the test sample, 0.2 ml of the above-mentioned suspension of the above-mentioned bacteria was added and sufficiently mixed to prepare a specimen for evaluation. The bacteria were stored in a dark place at 20 캜 and the fungus at 25 캜, respectively.

Next, 1 g of the sample solution for evaluation was aseptically collected 1 day, 4 days, 7 days, 14 days, and 28 days after the preservation. Then, 1 g of the lecithin polysorbate 80-added soybean casein And 9 ml of the digest liquid medium, respectively. 1 ml and 0.1 ml of the resulting solution were taken in a chalet, the bacteria were added to a soybean, casein and digest agar medium supplemented with lecithin polysorbate 80, and a fungus was added to a mixture of lignin and lactose in a glucose · peptone agar medium supplemented with lecithin polysorbate 80 (Mixing). Bacteria were cultured at 30 占 폚 for 4 days and fungi were cultured at 25 占 폚 for 7 days, and the number of live bacteria in the samples was measured.

The judgment was made by the following criteria based on the number of days until the added bacteria or fungus became below the detection limit (10 pieces / g or less). The results are shown in Table 1.

[Evaluation standard]

◎: Within 7 days, it was below the detection limit (10 pieces / g or less), and the bacteria killed were observed

?: Within 8 to 14 days, the detection limit was lowered (10 pieces / g or less), and the bacteria killed were observed

DELTA: exceeding the detection limit (10 pieces / g or less) exceeds 14 days

X: No death of the added bacteria was recognized
