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 which imparts excellent luster and smooth feel to hair and has good set-holding power.

[0002]

2. Description of the Related Art Conventionally, a set lotion and a hair spray have been used for the purpose of setting and maintaining hair.

A polymer compound for fixing hair is blended in these hair cosmetics. Examples thereof include polyvinylpyrrolidone-based polymer compounds, acidic polyvinyl ether-based polymer compounds, acidic polyvinyl acetate-based polymer compounds, acidic acrylic-based polymer compounds, and amphoteric acrylic-based polymer compounds.

On the other hand, for the purpose of imparting luster and smoothness to hair, oil components such as silicone oil, higher alcohols, liquid paraffin and ester oil, and cationic surfactants,
Cationic polymer compounds, nonionic surfactants, etc. are blended.

However, oils and the like added for the purpose of imparting luster and smoothness to the above-mentioned hair act as an inhibiting factor for the set holding power of the hair, so that the hair has a high set holding power while being applied to the hair. Until now, no hair cosmetics have been obtained that can give excellent gloss and smoothness.

[0006] Therefore, the present applicant, while having an excellent set retention, and made various studies to obtain a hair cosmetic composition also satisfactory in terms of gloss and smoothness results, R ₃ SiO
It has been found that the above object can be achieved by using a volatile hydrocarbon oil in addition to an organic silicone resin (MQ resin) consisting of _1/2 unit (M unit) and SiO ₂ unit (Q unit), and has already applied for a patent. (Japanese Patent Laid-Open No. 61-158914).

The weight average molecular weight of the MQ resin referred to here was from 1500 to 10,000. However, it was difficult to say that this MQ resin has a sufficient film-forming property because it is cracked as the silicone oil evaporates. In fact, when applied to hair, it had a sticky feeling and poor combability, and was not sufficient as a hair material. Further, this MQ resin does not have a sufficient film-forming property on the hair over time, and the film is easily broken by physical force, that is, combing or the like, and as a result, white crystals are deposited on the hair, resulting in appearance. It was something like a "dandruff".

Even if the resin is synthesized by changing the composition ratio of the M unit and the Q unit, the weight average molecular weight is at most 10,000.
It is the following. Therefore, the MQ resin is dry, and there is a limit to obtaining a physically strong film having a transparent feeling.

[0009]

DISCLOSURE OF THE INVENTION The present invention provides a hair makeup that imparts rich luster and smoothness to the hair, does not easily break the film due to combing, and has excellent setting power for the hair. The purpose is to provide fees.

[0010]

The present invention is characterized in that it is a hair cosmetic containing 0.1 to 50% by weight of an organic silicone resin represented by the following (A) and a solvent. (A) The ratio of R ₃ SiO _1/2 units (M units), R ₂ Si 0 units (D units) and SiO ₂ units (Q units) is 0.7.
/0.2 to 1.0 / 1.0, and an organic silicone resin having a MDQ weight average molecular weight of 10,000 to 30,000. (However, R represents a hydrocarbon having 1 to 6 carbon atoms or a phenyl group.) Note that R may be the same or different.

The solvent comprises one or more of volatile silicone oil and volatile hydrocarbon oil.

[0012]

In view of the above circumstances, the present inventors have made earnest studies and found that the above-mentioned properties of the MQ resin are mainly due to the small weight average molecular weight.

Then, by adding D units to the MQ resin consisting of M units and Q units and heating and condensing, MDQ resins having a weight average molecular weight of 2500 to 30000 could be obtained. Among them, MDQ resins having a viscosity of 10,000 or less cannot be used as a hair cosmetic composition because they are not cracked but have a sticky feeling.
It was found that the MDQ resin of No. 0 had the property of completely solving the above-mentioned drawbacks, and that it became a good film, and the present invention was completed based on this finding.

The organic silicone resin represented by the above (A) used in the present invention can be produced by various methods. As an example, an MQ resin composed of M and Q units may be added to D resin in a suitable solvent such as toluene, benzene, xylene, etc.
An MDQ resin is obtained through addition of a unit, heat condensation in the presence of an acidic catalyst, neutralization, filtration and desolvation. Alternatively, the M unit, the D unit and the Q unit are dissolved in a solvent and hydrolyzed in the presence of an acidic catalyst. Weight average molecular weight is GPC
It was determined by (gel permeation chromatogram).

The amount of the organic silicone resin used in the present invention is 0.1 to 50% by weight based on the total amount of the hair cosmetic composition.

The volatile hydrocarbon oil used in the present invention is, for example, Isopar (registered trademark) A, C, D,
Same E, same G, same H, same K, same L, same M (Exxon),
Examples thereof include Shelsol (registered trademark) 71, (Shell), Saltrol (registered trademark) 100, 130, 220 (Philipp). The volatile silicone oil is, for example, execol D which is a cyclic siloxane.
-4, D-5, chain siloxanes KF96 and KF5
You can raise 6. All of these are volatile, and one or more of them can be used. The content is preferably 0.1 to 99% by weight based on the total amount of the hair cosmetic composition.

Hair cosmetics containing the above-mentioned essential components are in the form of a solution or a solid depending on the blending amount thereof. That is, when the amount of the solvent is large, it takes the form of a solution and becomes solid as the amount of the organic silicone resin increases.

As a matter of course, in addition to the above-mentioned essential components, a water-in-oil type or an oil-in-water type is blended by blending an aqueous component and a suitable surfactant and making full use of the emulsification technique. It is also possible to use the emulsified composition of.

In addition to the above essential constituents, the hair cosmetic composition of the present invention contains, in addition to the above essential constituents, liquid paraffin, squalane, a lanolin derivative, and a high-grade compound within a quantitative and qualitative range that does not impair the effects of the present invention. Alcohols, various ester oils, silicone oils, polyalkylene glycol polyethers and their carboxylic acid oligoester compounds, oils such as terpene hydrocarbon oils, cationic surfactants,
You may mix | blend a cationic high molecular compound, a nonionic surfactant, a chemical | medical agent, and a fragrance | flavor. Even if these other components are blended in appropriate amounts, the hair cosmetic composition of the present invention is less likely to impair the hair holding power.
