Description

  The present invention relates to an emulsified hair styling agent containing a specific water-soluble polymer, a hair setting agent, a high-polymerization silicone, and a low-polymerization silicone. More specifically, the present invention relates to an excellent feeling of use (stickiness during use). The present invention relates to an emulsified hair styling composition that is excellent in stability over time and has a smoothness in use, a smoothness in use, a suppleness in finish, flexibility, smoothness, setting power, and durability of setting power.

Conventionally, hair setting agents such as resins and polymers have been used for hair styling products in order to maintain hair styling. For example, various polymers such as anionic, amphoteric, cationic, and nonionic are used, and these can be used individually or depending on the characteristics of the product, such as the strength and flexibility of the membrane and the speed of drying. Although used in combination, the hair setting agent by itself, when finished, sometimes forms a film on the hair surface and becomes too hard and may be stiff. Then, examination which uses a silicone derivative together for a touch improvement (for example, refer patent documents 1-2) has been made.
Silicone, as a basic property, can give an excellent feeling of use such as smoothness and smoothness, but each has its own characteristics depending on the degree of polymerization of silicone. It has been used for hair cosmetics and the like for split coats because it provides an excellent feeling of use such as sheath and smoothness, and also provides an excellent coat feeling. In addition to the smoothness, the low-polymerized silicone has features such as giving a supple, moist feeling, and so on. For example, Patent Documents 3 to 5) have been made.

On the other hand, emulsifiers for emulsifying oils containing an oil agent contain an emulsifier for emulsifying the oil agent. Sustainability, stickiness, and wrinkle may impair the feeling of use. Therefore, the formulation of a water-soluble polymer having emulsifying power instead of a surfactant has been studied (for example, see Patent Document 4).

  However, when a water-soluble polymer having emulsifying power such as an alkyl-modified carboxyvinyl polymer blended in JP-A-9-76641 is used, if the blending amount is increased in order to obtain excellent emulsification stability, The sticky feeling peculiar to the molecule may be felt, the smoothness and smooth feel obtained from the high-polymerized silicone and low-polymerized silicone may be impaired, and the combined use with the hair setting agent may cause the feeling of use to be impaired. It was. In addition, when the blending amount is suppressed, the temporal stability at high temperatures may not be sufficient. In addition, in order to improve the stability over time, the use effect may be impaired when the emulsifier is used in combination, for example, the setting effect is not sufficient or the smoothness by silicone cannot be obtained.
