Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an oil-in-alcohol type emulsified hair cosmetic. More specifically, for hair
The present invention relates to an oil-in-alcohol-type emulsified hair cosmetic which can give excellent luster and impart a smooth feel, and can adhere and repair split ends of hair.

[0002]

2. Description of the Related Art Conventionally, hair cosmetics contain oils such as silicone oil, high molecular weight dimethylpolysiloxane, high molecular weight methylphenylpolysiloxane, ester oil and hydrocarbon oil for the purpose of giving the hair smoothness. , Solubilization,
It is used after emulsification and dissolution.

In particular, silicone oil has a low surface tension,
Because it is excellent in hair familiarity and good gloss is obtained,
It is frequently used in recent years.

[0004]

However, there is a limit to the oil content, and when used in large quantities or when used for a long period of time,
There was a problem that hair became greasy.

[0005] Cationic surfactants are also frequently used for the purpose of imparting smoothness to hair. However, they do not give satisfactory satisfactory smoothness.
There was a problem that this was not good in terms of safety.

[0006] In general, hair is remarkably damaged by frequent repetition of hair washing, brushing, heat with a dryer, hair coloring, and a bleaching treatment, and as a result, the hair becomes dry and lumps or split ends. , Cut hair,
It is well known that it causes an increase in hair loss and the like and a decrease in strength.

On the other hand, conventionally, dimethyl silicone gum, polyvinylpyrrolidone-based polymer, acrylic acid-based polymer, polysaccharide, polypeptide and the like have been blended in hair cosmetics for the purpose of coating the split ends of hair.

[0008] Recently, it has been reported that hair cosmetics using a combination of a polysiloxane-oxyalkylene copolymer and a silicone derivative impart a good feel to hair and have excellent adhesion of split ends. (JP-A-6-157247).

[0009] However, these methods are good in imparting an excellent feel to hair,
It was still incomplete with respect to the adhesive effect of the split ends and the gloss of the hair.

When another polymer compound is blended, it has an adhesive effect on the split ends, but once it is peeled off, the effect cannot be reproduced, but also it becomes squeaky, sticky, sticky, etc. There are many problems on the touch surface, and there are also problems in appearance such as flaking.

[0011] Therefore, there has been a demand for a hair cosmetic which can solve these problems, efficiently bond the split ends, and give the hair a gloss and a good feel to the hair.

The present inventor has conducted intensive studies in view of the above viewpoints. As a result, the oil-in-alcohol emulsion obtained by using a specific polyether-modified silicone as the sole emulsifier has the amino acid of a peptide containing an amino group in the amino acid side chain. The incorporation of a silylated peptide in which a functional group containing only one silicon atom in the group is covalently bonded can solve the above-mentioned problem, and it has been found that hair cosmetics can be obtained with high emulsion stability, thereby completing the present invention.

[0013] The present invention provides a hair cosmetic composition which has an excellent function of repairing split ends, smoothes the hair, imparts a good feel, prevents split ends, and gives the hair a good gloss. The purpose is to:

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail.

The hair cosmetic composition of the present invention is an oil-lower alcohol-water system in which a lower alcohol is present in excess with respect to water, and one or more polyether-modified silicones represented by the general formula (1). This is an alcohol-in-alcohol type emulsified hair cosmetic using the above.

This oil-in-alcohol type emulsified hair cosmetic is
Completely different from conventional emulsification, it uses no hydrophilic nonionic surfactant, but rather uses polyether-modified silicone, which gels when contacted with water, as the only emulsifier, emulsifying oil in high alcohol concentration. Silylated peptide in which a functional group containing only one silicon atom is covalently bonded to the amino group of the amino group-containing amino group-containing peptide represented by the general formula (2) or (3) in an alcohol-in-oil type emulsion. This is an oil-in-alcohol type emulsified hair cosmetic containing

The polyether-modified silicone (d) used in the present invention is an organopolysiloxane having a polyoxyalkylene group represented by the general formula (1) and disclosed in JP-A-5-311076. is there.
In the present invention, commercially available products can be used.

Specific examples of the acyl group of R 'in the polyoxyalkylene group include a formyl group, an acetyl group, a propionyl group, a butyryl group, an acryloyl group, a benzoyl group and a toluoyl group. Specific examples of the alkyl group of (1) to (4) include a methyl group, an ethyl group, and an i-
Examples thereof include a propyl group, an n-propyl group, a t-butyl group, and an n-butyl group.

In the polyoxyalkylene group,
When a or b is less than 5, the polyether-modified silicone does not show a sufficient surfactant effect, and when a or b exceeds 50, the obtained hair cosmetic has a sticky feeling. Become like

Although the content of the polyoxyalkylene group in the polyether-modified silicone is not particularly limited, it is desirable that the content of the polyoxyalkylene group exceeds 20% by weight. This is because when the content of the polyoxyalkylene group is 20% by weight or less, the emulsifying effect of the polyether-modified silicone is significantly reduced.

M is an integer of 50 to 1000;
n is an integer of 0 to 40. This is because when m is less than 50, the emulsion stability is poor, and when m is 1000
If n exceeds 40, the resulting hair cosmetic will have a sticky feeling.

Although the molecular weight of the polyether-modified silicone is not particularly limited, it is 20,000 from the viewpoints of stability and usability.
More preferably, more preferably, 30,000-80
A range of 000 is preferred.

In addition, 25% of polyether-modified silicone
The viscosity at 0 ° C. is not particularly limited. However, in order to form a particularly stable emulsion and give the hair cosmetics a smooth feeling, the viscosity in a 50% by weight solution of octamethyltetrasiloxane or isoparaffin is 1%.
It is preferable that the thickness be in the range of 000 to 100,000 mPa · s.

The amount of the polyether-modified silicone used in the present invention is not particularly limited, but is preferably 1.0 to 30.0% by weight, more preferably 3.0% by weight, based on the total amount of the hair cosmetic. ２20.0% by weight. If the amount of the polyether-modified silicone is less than 1.0% by weight, stable emulsification is difficult, and if it exceeds 30.0% by weight, the hair cosmetic has a sticky feeling.

The type of the lower alcohol (b) used in the present invention is not limited, but is preferably methanol or ethanol. In view of safety, ethanol is particularly preferable. In addition, i-propanol, n-propanol, t-butanol, s-butanol, etc. are too hydrophobic and are difficult to emulsify.

The amount of the lower alcohol is preferably 3 times or more (weight ratio) and 30 times or less (weight ratio) with respect to the amount of water in the hair cosmetic. If the amount of the lower alcohol is less than three times, the polyether-modified silicone acts as an alcohol-in-oil type emulsifier, causing phase inversion. When the amount exceeds 30 times, the stability of the emulsified particles may be deteriorated.

The amount of the lower alcohol is usually 30.0 to 95.0% by weight based on the total amount of the hair cosmetic. In the prior art, in view of the difficulty in emulsification of the oil-in-alcohol type at a high alcohol concentration, the blending amount of the lower alcohol is 30.
The importance of the present invention is particularly understood when it is 0% by weight or more, more preferably 50.0% by weight or more.

(D) a polyether-modified silicone,
(B) The mixing ratio (weight ratio) of the lower alcohol is (d):
(B) = 1: 9 to 5: 5 is preferred. (D)
If / (b) is less than 1/9, the function of the polyether-modified silicone as an emulsifier is not exhibited, and (d) / (b)
If the ratio exceeds 5/5, the polyether silicone acts as an alcohol-in-oil type emulsifier, causing phase inversion.

The amount of (c) water used in the present invention is preferably 0.5 to 20.0% by weight, more preferably 1.0 to 15.0% by weight, based on the total amount of the hair cosmetic. .

Next, the (e) silylated peptide used in the present invention will be described in detail.

[Silylated peptide] The silylated peptide used in the present invention is a peptide containing an amino group in the amino acid side chain represented by the above general formula (2) or (3), which has only one silicon atom at the amino group. Functional groups are covalently bonded.

The silylated peptide represented by the general formula (2) is, for example, a silyl compound represented by the following general formula (4) and a peptide represented by the following general formula (5). It can be obtained by a condensation reaction.

Embedded image General formula (4) [Wherein, R ⁶ , R ⁷ , and R ⁸ represent an alkyl group having 1 to 3 carbon atoms, an alkoxy group having 1 to 3 carbon atoms, a hydroxyl group, or a halogen atom, and these R ⁶ , R ⁷ , and R ⁸ are All may be the same or different. a is an integer of 1 or 3, and X represents a halogen atom such as Cl, Br, F, and I. ]

Embedded image General formula (5) [Wherein, R ⁴ represents a residue excluding the amino group of a basic amino acid having an amino group at the terminal of the side chain, R ⁵ represents a side chain of an amino acid other than R ⁴ , m is 0 to 200, n Is 0 to 200,
m + n is 1 to 200. ]

The silylated peptide represented by the general formula (3) is, for example, a silyl compound represented by the following general formula (6) and a peptide represented by the above general formula (5). It can be obtained by a condensation reaction.

Embedded image General formula (6) [Wherein, R ⁶ , R ⁷ and R ⁸ are an alkyl group having 1 to 3 carbon atoms,
It represents an alkoxy group, a hydroxyl group or a halogen atom having 1 to 3 carbon atoms, and all of R ⁶ , R ⁷ and R ⁸ may be the same or different. a represents an integer of 1 or 3. ]

[Characteristics of Silylated Peptide] The silylated peptide represented by the general formula (2) and the silylated peptide represented by the general formula (3) are, as is clear from their chemical structural formulas, respectively. A silyl functional group containing a silicon atom based on the silyl compound represented by the formula (4) or the silyl compound represented by the general formula (6) and a peptide moiety based on the peptides represented by the general formula (5) When formulated into hair cosmetics, it has excellent extensibility, friction reduction, gloss and gloss imparting effects, water repellency imparting effects, etc., possessed by the silyl functional group portion, as well as absorption into the hairs possessed by the peptide portion. Wearing action, accompanying volume up of hair, giving firmness,
The protective action and the moisturizing action by the film formation can be simultaneously exhibited.

Further, since the peptides have good sorption property to damaged hair, the above-mentioned silylated peptide can be attached to damaged hair which is difficult to sorb with high molecular weight silicone via a peptide portion.
Since the silyl functional group can be sorbed, it is possible to improve the feel of damaged hair and contribute to the recovery of strength.

Therefore, when the hair cosmetic is prepared by blending the silylated peptide, the silylated peptide imparts luster and moisture to the hair, smoothes the hair, and improves the combability of the hair. It is possible to prevent the occurrence of split ends and cut hairs and to recover the strength of damaged hairs.

The silylated peptide represented by the general formula (2) or the silylated peptide represented by the general formula (3) has a low molecular weight silyl functional group bonded to the peptide portion, Since the hair is sorbed by a normal peptide sorption mechanism, the silylated peptide can be reversibly desorbed from the hair by washing with a detergent containing no peptide.

In the silylated peptide represented by the general formula (2) or the silylated peptide represented by the general formula (3),
R ¹ , R ² , and R ³ are specified as described above because the silylated peptide represented by the general formula (2) or the silylated peptide represented by the general formula (3) has a water solubility. This is for maintaining good storage stability in water-soluble hair cosmetics.

Also, a is specified as 1 or 3 because when a is 2, the state of the silyl compound represented by the general formula (4) or the silyl compound represented by the general formula (6) This is because when the storage stability is poor and a is larger than 3, the proportion of the silyl functional group portion in the whole molecule becomes small, and the properties possessed by the silyl functional group cannot be sufficiently exhibited.

[Peptide moiety in silylated peptide]
In the silylated peptide represented by the general formula (2) or the silylated peptide represented by the general formula (3), R ⁴ is a residue excluding a terminal amino group of a basic amino acid having an amino group at a terminal of a side chain. However, examples of the basic amino acid having an amino group at the terminal of the side chain as described above include lysine, arginine, and hydroxy phosphorus. Further, R ⁵ represents a side chain of an amino acid other than R ^4, but as such acids, e.g., glutamic acid, aspartic acid, alanine, serine, threonine, valine, methionine, leucine, isoleucine, tyrosine, phenylalanine, proline , Hydroxyproline and the like.

５０50 for the following reason.

That is, when m is larger than the above range, the number of silyl functional groups bonded to the amino group in the side chain increases, and the sorption effect of the peptide on the original hair decreases. When the ratio of the silyl functional group portion to the peptide is small, the characteristics of the silyl functional group portion cannot be sufficiently exhibited, and when m + n is larger than the above range, the sorption property and permeability to hair as a peptide are low. In addition to reducing the molecular weight of the peptide, the peptide tends to aggregate during storage and storage stability is reduced.

The above-mentioned m, n and m + n are theoretically integers. However, when the peptide portion is a hydrolyzed peptide as described later, the hydrolyzed peptide is obtained as a mixture of those having different molecular weights. Therefore, the measured value is an average value.

The peptides represented by the general formula (5) include amino acids, peptides, esters of amino acids or peptides, and the like. As amino acids, alanine, glycine, valine, leucine, isoleucine, proline, phenylalanine, tyrosine, serine, threonine, methionine, arginine, histidine, lysine, asparagine, aspartic acid, glutamine, glutamic acid, cystine, cysteine, cysteic acid, tryptophan, Hydroxyproline, hydroxylysine, O-phosphoserine, citrulline and the like.
