Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic composition, and more particularly to a hair cosmetic composition having excellent hair set-holding power while providing excellent gloss and smooth feel.

[0002]

2. Description of the Related Art Conventionally, in various hair cosmetic compositions such as shampoos and conditioners, silicone oils, ester oils and hydrocarbons have been used for the purpose of imparting various feelings such as smoothness, softness and moisturizing feeling to hair. Oils such as oil, and cationic surfactants are used in combination. In particular, since silicone oil has a low surface tension and easily spreads evenly on hair, good gloss and luster are obtained, and the variety of feel to be imparted is excellent.
Widely used.

However, in the conventional hair cosmetic composition containing silicone oil, a large amount of silicone oil must be blended in order to impart sufficient smoothness, which results in loss of the waist of the hair, There was a problem that the set holding power was reduced.

Therefore, development of a hair cosmetic composition having a high set-holding power while giving sufficient smoothness is under way. For example, a specific hard silicone polymer is volatilized such as octamethyltetrasiloxane. A composition prepared by dissolving in a volatile substance (US Pat. No. 4902499),
A composition using a non-rigid crosslinked silicone polymer (Japanese Patent No. 3043816) has been proposed. However, all of these were still insufficient in smoothness.

Further, a cosmetic composition using a silica core-silicone shell body (Japanese Patent Laid-Open No. 10-114622, etc.) has been proposed, but the silica core-silicone shell body can control the degree of polymerization of organosiloxane during emulsion polymerization. Since it is difficult, stable performance is difficult to obtain.
Moreover, the smoothness was not sufficiently satisfactory.

On the other hand, inorganic powders such as silica and mica,
Hair cosmetics using organic powder such as acrylic resin and silicone resin (JP-A-57-140708, JP-A-4-124121)
Japanese Patent Laid-Open No. 6-80559, etc.) have been proposed.
However, although these give a silky feel, they are insufficient in smoothness and moisturizing feeling.

[0007]

As described above, the development of a hair cosmetic composition having a high set-holding power while giving a sufficient smoothness has been advanced, but the smoothness is insufficient. However, there are problems such as lack of stability in performance, and there is still no satisfactory product.

The present invention has been made in view of the above circumstances, and provides a cosmetic composition for hair that has a high set holding power while giving a smooth feel, and has no variation in performance. The purpose is to provide.

[0009]

Means for Solving the Problems As a result of intensive studies for achieving the above-mentioned object, the present inventors have found that by blending a silicone emulsion in which a mixture of silica sol and polyorganosiloxane is emulsified The present invention has been completed by finding that a hair cosmetic composition having a good set-holding power while giving a smooth feel and having no variation in performance can be obtained.

That is, according to the present invention, (A) silica sol and (B) the following average composition formula [I] R ¹ _a SiO 2 _{(4-a) / 2} ... [I] (wherein R ¹ is the same or different) A monovalent hydrocarbon group or a substituted hydrocarbon group, a represents a number in the range of 1.8 to 2.2), and contains a mixture of polyorganosiloxanes, and the content of SiO ₂ in the component (A) is And a silicone emulsion in which the weight ratio of the component (B) is 1:99 to 50:50, and a hair cosmetic composition.

Examples of the liquid that is a dispersion medium include water, alcohol, ethylene glycol, and the like, and water is preferable because an emulsion that can be easily mixed with hair cosmetics can be obtained. That is, as the silica sol of the component (A), an aqueous silica sol which is a dispersion in water is preferable. The aqueous silica sol is classified into acidic ones and alkaline ones according to the characteristic classification, and it is appropriately selected and used depending on the emulsification conditions at the time of emulsion preparation.

In order to obtain the effects of the present invention, the weight ratio of the SiO ₂ content in the silica sol as the component (A) and the polyorganosiloxane as the component (B) must be 1:99 to 50:50. If the proportion of SiO ₂ in the component (A) is less than the above range, sufficient smoothness and set holding power cannot be obtained. On the other hand, if it exceeds 50% by weight, the set holding power is high but smoothness is high. Is insufficient. The weight ratio of the SiO ₂ component in the component (A) to the component (B) is preferably 5:95 to 40:60, more preferably 10:90 to 30:70.

Further, the content of the silica sol of the component (A) and the polyorganosiloxane of the component (B) in the hair cosmetic composition is appropriately determined depending on the use, but in order to sufficiently obtain the effects of the present invention. For example, when the hair cosmetic composition is a shampoo composition, the range is preferably 0.1 to 10% by weight, and the hair conditioner composition is preferably 0.1 to 20% by weight. More preferably, for shampoo compositions, 0.

The silica sol as the component (A) and the polyorganosiloxane as the component (B) are mixed in advance and the mixture is emulsified and dispersed in an aqueous medium using an emulsifier, that is, a mixture of the silica sol and the polyorganosiloxane. Is added to the hair cosmetic composition in the form of the emulsion (silica sol-silicone mixture emulsion). The emulsion particle size is usually in the range of 0.1 to 500 μm, but depending on the application, if the particle size is too large, the stability in the hair cosmetic composition may decrease, so the desired hair cosmetic composition.

It is desirable to add 5 to 40% by weight. When the content of this component is less than 5% by weight, detergency and foaming at the time of cleaning become insufficient, and when it exceeds 40% by weight, the viscosity of the obtained composition becomes high and usability deteriorates.

Hair gel, hair oil, hair dye, ski oil, baled oil, set lotion, tic, hair tonic, hair liquid, hair spray, pomade, and the like. In addition, examples of the form include solid, gluous, liquid, and paste forms.

The hair cosmetic composition of the present invention can have high set holding power while imparting excellent smoothness to the hair. Moreover, the emulsion of the mixture of silica sol and polyorganosiloxane has a silica core
Since there is no problem that the degree of polymerization is difficult to control as in the case of a silicone shell emulsion, there is no variation in performance.

It is possible to improve various tactile sensations that are required, such as feeling, dryness, strain, and volume.

The present invention can obtain the following effects particularly when applied to a shampoo composition. That is, shampoo is usually used in combination with a rinse or conditioner, but by using the shampoo composition of the present invention, and then using the rinse or conditioner, the respective effects are synergistically synergized. The smoothness of hair can be greatly improved.
