Abstract

PURPOSE:To provide a hair cosmetic such as set lotion, hair spray, etc. containing a specific organic silicone resin and a volatile hydrocarbon oil, giving excellent gloss and smooth feeling to the hair, and having high set-keeping property. CONSTITUTION:The objective hair cosmetic contains (A) 0.1-50wt% organic silicone resin of formula (R is 1-6C hydrocarbon group or phenyl; n is 1.0-1.8) and (B) 0.1-99wt% volatile hydrocarbon oil having a boiling point of 60-260 deg.C. When the amount of the component B is high, the cosmetic has the form of a solution, and turns gradually to a solid state by increasing the amount of the component A. An emulsified composition can be produced by compounding the composition further with an aqueous component and a proper surfactant to an extent to keep the water-repellency. It may be compounded further with liquid paraffin, squalane, higher alcohol, medicinal drug component, perfumery, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a hair cosmetic that imparts excellent gloss and smooth feel to hair, and has good set-holding power.

[Prior Art] Conventionally, setting lotions, hair sprays, and the like have been used to set and maintain hair.

These hair cosmetics contain polymer compounds for hair fixation. Examples include polyvinylpyrrolidone polymer compounds, acidic polyvinyl ether polymer compounds, acidic polyvinyl acetate polymer compounds, acidic acrylic polymer compounds, and amphoteric acrylic polymer compounds.

On the other hand, for the purpose of giving shine and smoothness to the hair, oils such as silicone oil, higher alcohol, liquid paraffin, and ester oil, as well as cationic surfactants, cationic polymer compounds, and nonionic surfactants are blended. .

However, the above-mentioned oils added for the purpose of giving shine and smoothness to the hair act as a hindering factor to the hair's set retention power, so it is possible to create a product that has high hair retention power and is excellent for hair. Until now, hair cosmetics that give shine and smoothness have not been available.

[Problems to be Solved by the Invention] In view of the above circumstances, the present inventors sought to obtain a hair cosmetic that has excellent hair retention ability and is also satisfactory in terms of gloss and smoothness. As a result of extensive research, we discovered that the above objectives could be achieved by using a volatile hydrocarbon oil in addition to a specific organic silicone resin.
Based on this knowledge, we have completed the present invention.

Means for Solving Problems c] That is, the present invention provides 0.1 to 50% by weight of an organic silicone resin shown in (A) below and 0.1 to 50% by weight of a volatile hydrocarbon oil shown in (B) below. This hair cosmetic is characterized by containing 99% by weight.

(A) An organic silicone resin comprising units of the average formula RnSiO(" (R represents a hydrocarbon group having 1 to 6 carbon atoms or a phenyl group, and n represents a value from 1.0 to 1.8).

(B) A volatile hydrocarbon oil having a boiling point in the range of 60 to 260°C at room temperature.

The organic silicone resin represented by (A) used in the present invention includes R35iO unit, R25io unit, R5103
consisting of an appropriate combination of units and SiO units,
The proportions are selected to satisfy the average formula Rn5i04, where n represents a value from 1.0 to 1.8, and preferably have an average molecular weight of about 1500 to 1oooo.

The above organic silicone resin is soluble in benzene and can be produced by various methods. -For example, general formula R3Si
X, R25iX2, R51X3 and SiX+
(X is a hydrolyzable group, such as chlorine, bromine, fluorine,
A compound represented by alkoxy (e.g., methoxy, ethoxy, etc. group, acyloxy group) is added to a suitable solvent such as toluene, benzene, xylene, etc. depending on the desired resin composition, and then this solvent is mixed with a suitable solvent. Add in sufficient amount of water to obtain the desired hydrolysis and co-condensation in an acidic solvent. removing the aqueous phase from the resulting two-phase system and neutralizing the remaining resinous material with a sufficient amount of sodium bicarbonate or other alkaline substance;
By distilling off the solvent, the desired organic silicone resin can be obtained.

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

Further, the volatile hydrocarbon oil used in the present invention is a hydrocarbon oil having a boiling point in the range of 60 to 260°C at room temperature,
For example, Isopar (registered trademark) A, C1 D, E, G, H1 K, Isopar M (Exxon), Shellzol (registered trademark) 71, (Shell), Tsurtrol. (Registered trading company + 100, 130, 220 (
Philips Co., Ltd.).

All of these are volatile and can act as a solvent for the organic silicone resin.

The blending amount is 0.1 to 99% by weight based on the total amount of hair cosmetics.

Hair cosmetics containing the above-mentioned essential ingredients take on the form of a solution to a solid depending on the amount of the ingredients. That is,
When the amount of volatile hydrocarbon oil is large, it takes the form of a solution, and as the amount of organic silicone resin increases, it becomes solid.

Naturally, in addition to the above essential ingredients, by blending aqueous components and appropriate surfactants and making full use of emulsification technology, water-in-oil or oil-in-water emulsion compositions can be created without sacrificing water repellency. It is also possible to turn it into an object.

In addition to the above-mentioned essential components, the hair cosmetic of the present invention includes:
Depending on the purpose, liquid paraffin, squalane, lanolin derivatives, higher alcohols, various ester oils, silicone oils, polyalkylene glycol polyethers and carboxylic acid oligoesters thereof, within a quantitative and qualitative range that does not impair the effects of the present invention. Compounds, oils such as terpene hydrocarbon oils, cationic surfactants, cationic polymer compounds, nonionic surfactants, drugs, and fragrances may be blended. Even if appropriate amounts of these other ingredients are blended, the hair cosmetic composition of the present invention is unlikely to impede the hair set retention ability.

Hereinafter, the present invention will be explained in more detail with reference to Examples. The present invention is not limited by these. All compounding amounts are weight %.
