JP6680550B2 - Non-emulsifying hair styling composition - Google Patents

Description

  The present invention relates to a non-emulsifying hair styling composition.

  The non-emulsifying hair styling composition is required to have various effects such as hair styling property, combability, hair styling durability, and composition stability. Therefore, various attempts have been made to obtain a hair styling composition having the above-mentioned effects by blending specific components (for example, Patent Documents 1 and 2). However, a non-emulsifying type hair styling composition that has comprehensively good hair styling properties, combability, hair styling durability, composition stability, etc. has not been obtained, and it is very difficult to obtain the composition. Has become a problem.

  Further, in general, when a non-emulsifying hairdressing composition is applied to hair, it is necessary to dry the hair to which the above composition is adhered in order to obtain a hairdressing effect because the water wets the composition. For this reason, there is a problem in simplicity because it takes a long time to dry, the hair styling ability decreases if it is not completely dried, and it is necessary to stylist hair while heating with a dryer. Further, when a dryer is used, there is a problem in that the damage to hair progresses due to heat.

  Patent Document 3 discloses a hairdressing composition containing a specific inorganic powder, volatile oil, or the like. The hair styling agent has effects such as suppressing stickiness of the hair, but the hair styling agent disclosed in Patent Document 3 is an emulsifying type and has different performance from the non-emulsifying type hair styling composition, and therefore is not separately prepared. There is a demand for investigation of emulsion type hair styling compositions.

  Hereinafter, the non-emulsifying hair styling composition of the present invention will be described. Hereinafter, the non-emulsifying hair styling composition of the present invention is also simply referred to as "composition".

[Non-emulsifying hair styling composition]
The composition of the present invention contains a thickener (A) and diatomaceous earth (B) described below. The composition preferably further contains an acrylic or vinyl nonionic resin (C) (hereinafter also referred to as “nonionic resin (C)”), and a hetero atom other than an oxygen atom is intramolecularly contained. It is also preferable to include a polyhydric alcohol (D) not included in the above (hereinafter also referred to as “polyhydric alcohol (D)”). The composition preferably contains a nonionic resin (C) and a polyhydric alcohol (D). Moreover, you may contain another component (E) as needed.
The composition of the present invention is a non-emulsifying type. For this reason, compared with a general emulsion type hair styling composition, there are advantages that the composition has good elongation and no stickiness due to oil content.

<Thickener (A)>
The thickener (A) is at least one selected from anionic thickeners and nonionic thickeners. By including the thickener (A), when the composition is applied to the hair, wetting of the hair can be reduced, and the hair can be easily prepared.

  All the hair styling compositions produced in Examples 1 to 26 were evaluated as good in all the evaluation items (1) to (14). Therefore, the composition of the present invention has less wetting of the hair, simple hair styling, and can give firmness, elasticity and volume to the hair, immediate effect of hair styling, combability, hair styling persistence and composition. It can be seen that the stability of is good. In addition, it satisfies the properties required for a hair styling composition, such as uniform application properties, no stickiness or stickiness of hair after application, no flaking, and lasting power of hair styling.

  Among them, the compositions using an anionic thickener as the thickener (A) (for example, Example 3 and Example 10) are compositions using a nonionic thickener as the thickener (A). Compared to the product (Example 11), there are many items that have been evaluated more excellently, and it is particularly preferable from the viewpoint that the hair is given firmness and elasticity and that the hair can be adjusted without stickiness.

  Moreover, compared with the compositions (Examples 1 to 17) containing the thickener (A) and diatomaceous earth (B), the compositions (Examples 18 to 21) further containing the nonionic resin (C), There are many items that have been evaluated more excellently, and it is particularly preferable in terms of immediate effect on hair styling. In addition, in addition to the thickener (A) and diatomaceous earth (B), a composition (Example 22) further containing a polyhydric alcohol (D) has many items that have been evaluated more excellently, and in particular, for the hair. It is preferable from the viewpoint of reducing stiffness. And the composition (Examples 23-26) containing a thickener (A), a diatomaceous earth (B), a nonionic resin (C), and a polyhydric alcohol (D) was the item which was evaluated more excellently. It can be seen that there are more, and it is excellent overall.

  In Comparative Example 1, the content of the thickener (A) was small, in Comparative Example 3, the content of the diatomaceous earth (B) was small, and in Comparative Example 5, the cationic polymer polyquaternium-37 was used as the thickener. In Comparative Examples 6 and 7, silica and kaolin were used instead of diatomaceous earth (B), respectively. These compositions resulted in wet hair. Therefore, a dryer is required, and the hair is not easily prepared and damage is caused.

The composition produced in Comparative Example 2 contained a large amount of the thickener (A), so that the composition could not be applied uniformly, resulting in poor hairdressing convenience.
Since the composition produced in Comparative Example 4 contained a large amount of diatomaceous earth (B), the composition was stiff.

In Comparative Example 6, silica was used instead of diatomaceous earth (B), and in Comparative Example 7, a composition in which kaolin was used instead of diatomaceous earth (B) was used. Silica and kaolin are often used in hair styling compositions as a powder having a hair styling effect, but silica cannot be stably incorporated into this thickener, and kaolin cannot provide a volume effect. Also, both resulted in wet hair.
