Description

The present invention relates to shampoo compositions.

The purpose of shampoos is to cleanse the hair and scalp, but many today's consumers have better lather, smoother finger passage and easier rinsing than those with good cleansing power that can damage the hair. There is a tendency to prefer shampoos that have an excellent feel. Furthermore, not only when shampooing, but also in all processes, such as the good feel of "after towel drying" after removing the moisture from the hair with a towel after washing the hair, and the good smoothness after drying the hair. Consumers want the product to feel good to the touch. In particular, consumers who do not use a dryer tend to demand good finger passage after towel drying and lightness of hair after towel drying because the wet hair condition lasts for a long time after towel drying. It is in. On the other hand, as a feeling that the hair has been sufficiently washed, it is preferable that the hair is soft and voluminous and that the state lasts for a long time.

Various studies have been conducted to meet the above requirements, and for example, the use of an anionic surfactant and a specific cationized polymer has been proposed as a shampoo having a smooth feel during rinsing (see, for example, Patent Document 1). ). However, the above proposal has a problem that the feel from after towel drying to drying is not satisfactory.

In addition, as a technique for imparting a voluminous feel to hair after shampooing, a shampoo containing a cationic polymer such as a quaternary cellulose derivative, a water-soluble collagen derivative, and a polysiloxane, and a shampoo containing an acylated peptide are proposed. (See, for example, Patent Documents 2 and 3). However, these proposals have a problem that the goodness of finger passage after towel drying is insufficient and the storage stability at high temperature cannot be ensured.

Therefore, although it is strongly desired to develop a shampoo composition which is excellent in finger passage after towel drying and lightness of hair after towel drying and has good storage stability at high temperature, such a shampoo The composition was not present.

⊚: Of the 20 people, 16 or more were judged to be “good”.
◯: Of the 20 persons, 11 or more and 15 or less were judged to be “good”.
Δ: Of the 20 persons, 6 or more and 10 or less were judged to be “good”.
X: Of the 20 persons, 5 or less were judged to be “good”.

-Storage stability at high temperature-
A 50 mL transparent glass bottle (trade name: screw vial, manufactured by Tech Jam) was filled with about 40 mL of each shampoo composition, and the liquid separation after storage at 50 ° C. for 1 month was evaluated according to the following criteria. ..

<< Evaluation Criteria >>
⊚: Stable without liquid separation ○: Very slight liquid separation is observed Δ: Liquid separation is observed ×: Remarkable liquid separation is observed

Each component used in Examples and Comparative Examples is as shown in Table 10 below.

The shampoo composition of the present invention is excellent in finger passage after towel drying, lightness of hair after towel drying, and good storage stability at high temperature. Therefore, for example, shampoo for skin cleansing, damage care. It can be suitably used for shampoos for hair, mild shampoos, rinse-in shampoos, shampoos for removing dandruff, and the like.
