Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil-in-alcohol type hair setting composition, and more particularly to a hair setting agent which imparts excellent gloss to a hair, imparts a smooth feel, and has good holding power. And an oil-in-alcohol type hair setting composition capable of adhering and repairing split ends of hair.

[0002]

BACKGROUND OF THE INVENTION Conventionally, silicone oils, high-molecular-weight dimethylpolysiloxanes, high-molecular-weight methylphenylpolysiloxanes, esters have been used in hair cosmetics for the purpose of imparting gloss and smoothness to hair. Oils such as oils and hydrocarbon oils are used after being solubilized, emulsified and dissolved. In particular, silicone oils have a low surface tension, are excellent in the familiarity of hair, and have good luster, and are widely used in recent years. However, there is a limit to oil content, and if used in large quantities or used for a long time by consumers,
There was a disadvantage that the hair became greasy. Also, cationic surfactants are often used for the purpose of imparting smoothness, but they do not give satisfactory gloss, and there is a drawback that if they are blended in a large amount, safety is not preferable.

[0003] In general, hair is remarkably damaged and deteriorated by frequent and repeated hair washing, brushing, heat treatment with a dryer, hair coloring, and beauty treatment with a bleaching agent. Cut hair,
It is well known to cause an increase in hair loss and the like and a decrease in strength.

On the other hand, hair setting agents which have been widely used in the past are obtained by dissolving a film-forming polymer compound in water, a lower alcohol, or a mixed solvent thereof.
The polymer compound blended here has the effect of fixing the hairs together and holding the set, but the ones that have been used conventionally have stickiness in the process of applying to the hair and drying it. It wasn't smooth. In order to solve such disadvantages, attempts have been made to improve the feel in use by adding oils and fats for cosmetics, surfactants, and the like to the polymer compound. However, a hair setting agent having both sufficiently satisfactory set holding power and use feeling has not yet been obtained.

[0005] Recently, a hair treatment agent containing an amphoteric polymer compound and a cationic polymer (Japanese Patent Publication No. 2-4444).
No. 6, Japanese Patent Publication No. 3-14805) and a hair treating agent comprising an amphoteric polymer compound and an anionic polymer (Japanese Patent Publication No. 3-21524). However, these treatment agents are not satisfactory in terms of non-stickiness and smoothness from application to drying, and also have a feeling of roughened finished hair, which is not satisfactory.

More recently, for the purpose of coating the split ends of hair, hair cosmetics using a combination of a polysiloxane-oxyalkylene copolymer and a silicone derivative have been developed. Has been reported to be good and excellent in adhesion of split ends (Japanese Patent Application Laid-Open No. 6-157247). However, even this method was still incomplete in terms of set holding power and hair smoothness.

Therefore, the fixing power between the hairs is sufficient,
It is desired to develop a hair setting agent composition which has a resilient and non-sticky coating film, has excellent style holding power, and is non-sticky, smooth and easy to give in the process from application to drying. I was

[0008]

Under these circumstances, the present inventors have conducted intensive studies and as a result, have found that a specific amphoteric polymer has been added to an oil-in-alcohol emulsion obtained by using a specific polyether-modified silicone as the sole emulsifier. It has been found that a hair setting agent composition having both excellent set holding power and good feel can be obtained when used in combination, and the present invention has been completed.

That is, the present invention provides (a) an oil component;
(C) water, (d) one or more polyether-modified silicones represented by the following general formula (1) as an emulsifier, and (e) betaine represented by the following general formula (2) The molecular weight of the dialkylaminoalkyl acrylate copolymer is from 50,000 to 500,000.
An oil-in-alcohol type hair setting composition comprising one or two or more amphoteric polymers of No. 00.

The groups, y and z are positive integers, and represent a number such that the ratio of y: z is in the range of y: z = 2: 8 to 8: 2. )

Next, the configuration of the present invention will be described. The oil-in-alcohol-type hair setting composition according to the present invention is an oil-lower alcohol-water system in which a lower alcohol is present in excess with respect to water, and comprises one or more polyether-modified silicones represented by the general formula (1) or An oil-in-alcohol hair setting composition comprising a stable oil-in-alcohol emulsion containing two or more types and an amphoteric polymer represented by the general formula (2).

That is, the oil-in-alcohol type hair setting composition of the present invention does not use a hydrophilic nonionic surfactant, but rather uses a polyether-modified silicone which gels when contacted with water, which is completely different from conventional emulsification. It is a completely new oil-in-alcohol type hair setting composition which emulsifies an oil in a high alcohol concentration as a sole emulsifier and further contains an amphoteric polymer.

The oil used in the present invention includes liquid paraffin, squalane, lanolin derivatives, higher alcohols, various ester oils, avocado oil, palm oil, tallow, jojoba oil, silicone oil, polyalkylene glycol polyether and its carboxylic acid. Oligoester compounds,
And terpene hydrocarbon oils. Oil content is 0.5 to 70.0% by weight, especially 1.0 to 50.0% by weight
Is preferred. If the amount is less than 0.5% by weight, the effect of the present invention, particularly the smoothness, cannot be realized, and if it exceeds 70.0% by weight, stickiness occurs.

The type of the lower alcohol used in the present invention is not particularly limited, but methanol or ethanol is preferable, and ethanol is particularly preferable in view of safety. In addition, i-propanol, n-propanol,
Since t-butanol, s-butanol and the like are too strong in hydrophobicity to be emulsified, it is desirable to use them in combination with ethanol. The amount of the lower alcohol is preferably at least 3 times (weight ratio) the amount of water in the composition.
If the amount of the lower alcohol is less than three times, the entire system is gelled by the polyether-modified silicone, and the viscosity increases to make it difficult to emulsify. Further, in view of the difficulty in emulsifying an oil-in-alcohol type at a high alcohol concentration in the prior art, the compounding amount of the lower alcohol is 30.0% by weight or more, more preferably 40.0% by weight or more in the composition. In particular, the importance of the present invention is understood.

The polyether-modified silicone used in the present invention is an organopolysiloxane having a polyoxyalkylene group represented by the general formula (1).

Specific examples of the acyl group of R ′ include a formyl group, an acetyl group, a propionyl group, a butyryl group, an acryloyl group, a benzoyl group, and a toluoyl group. Specifically, a methyl group, an ethyl group, an i-propyl group, an n-propyl group,
A t-butyl group and an n-butyl group are exemplified.

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 setting composition has a sticky feeling. Will have.

The content of the polyoxyalkylene group is not particularly limited.
It is desirable to have more than% by weight. This is because when the content of the polyoxyalkylene group is 20% by weight or less, the thickening 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 exceeds 1000 and n exceeds 40, the obtained hair setting composition has a sticky feeling. Because it becomes.

The molecular weight of the polyether-modified silicone used in the present invention is not particularly limited, and its viscosity at 25 ° C. is not particularly limited. However, a hair setting agent composition which forms a particularly stable emulsion and has a dry feeling. In order to obtain a product, the polyether-modified silicone used in the present invention has a viscosity in the range of 1,000 to 100,000 cps as a 50% by weight solution of octamethyltetrasiloxane or isoparaffin. Preferably, there is. The molecular weight is 20,000 or more, preferably 30,000 or more, from the viewpoint of stability and usability.
A range of 80,000 is preferred.

The amount of the polyether-modified silicone used in the present invention is not particularly limited, but is preferably 1.0% by weight or more, more preferably 3.0% by weight or more. Further, preferably 30.0% by weight or less,
It is more preferably at most 20.0% by weight. In the hair setting composition of the present invention, 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 setting composition This is because the object has a sticky feeling. Such a polyether-modified silicone is known as a gelling agent, and is described, for example, in JP-A-5-311076.

In the present invention, the blending ratio (weight ratio) of the polyether-modified silicone and the lower alcohol is: polyether-modified silicone: lower alcohol = 1: 9 to 5: 5
It is preferred that If the polyether-modified silicone is less than 1/9 of the lower alcohol, the polyether-modified silicone will not function as an emulsifier. If the lower alcohol is less than the same amount as the polyether-modified silicone, the thickening effect of the polyether-modified silicone will be remarkable and stable. Emulsification becomes difficult.

The amphoteric polymer used in the present invention comprises:
A betaine-containing dialkylaminoalkyl acrylate copolymer represented by the general formula (2), having a molecular weight of 50,0
Those having a number of 00 to 500,000 can be used alone or in combination of two or more.

Here, y and z are positive integers, respectively, and the ratio of y: z is in the range of y: z = 2: 8 to 8: 2. When the ratio of z to y exceeds y: z = 2: 8, there is a problem in solubility in alcohol and water, and the hair washing property deteriorates. Furthermore, there is a problem in affinity with hair, and flaking becomes easy. on the other hand,
When the ratio of z to y is smaller than y: z = 8: 2, the film forming power is inferior, and there is a problem in setting force. Furthermore, the hygroscopicity increases and stickiness occurs.

Among these, particularly preferred amphoteric polymers are those represented by the following component (A).
