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 combability and smooth feel to the hair and protects the hair from heat and brushing.

[0002]

2. Description of the Related Art Conventionally, various hair cosmetics such as hair treatments and hair rinses have been used in order to give the hair gloss and elasticity or to care for damaged hair. For example, in order to give the hair gloss and smoothness, hair cosmetics containing an oil component such as silicone oil, higher alcohol, liquid paraffin, or ester oil are used. Further, in order to give the hair flexibility and antistatic effect, hair cosmetics containing a cationic surfactant or a cationic polymer compound are used. Further, in order to protect the hair from heat of a drier, there is a hair cosmetic containing a water-soluble polymer compound.

However, hair cosmetics containing oils have the drawback of giving a feeling of foreign matter when applied to the hair, such as stickiness, and also have adhesiveness themselves.
The physical resistance to combing and brushing also increases. In addition, a hair cosmetic containing a cationic surfactant or a cationic polymer compound is electrically adsorbed only to a negatively charged portion of the hair surface, and the adsorption power is insufficient, and the uniformity is also improved. It is inferior and the comb road is not good.
Further, hair cosmetics containing a water-soluble polymer have drawbacks in that the hair after treatment has a large stickiness and adhesiveness, and the treated hair has a sensation of foreign matter and poor combability.
In order to overcome these drawbacks, hair care products using silicone gum have been proposed in recent years (Japanese Patent Laid-Open Publication No. 63-63119).
-313714 and JP-A-1-168609),
It has drawbacks such as poor elongation during application and lack of a moist finish.

The present invention provides (i) formula [I]:

Embedded image [Wherein R ¹ and R ² are methyl groups or hydroxyl groups; n ¹ is an integer of 4,000 to 9,000], and 0.01 to 10% by weight of dimethyl silicone gum, and (ii) average A hair cosmetic composition comprising 0.1 to 20% by weight of polyethylene glycol having a molecular weight of 10,000 or more. The hair cosmetic composition further comprises the formula [II]:

Embedded image [In the formula, l is 0 or 1, and m is an integer such that l + m = 1;
n ² means an integer of 1,000 to 2,000] or the formula [III]:

[Chemical 6] [In the formula, n ³ and n ⁴ mean an integer of 500 to 4,000] and may include a cationic polymer.

Methyl is preferable as R ¹ and R ² in the dimethyl silicone gum of the formula [I] used in the hair treatment composition of the present invention, and n ¹ is 5,500 to 9,0.
00 is preferable. Typical examples of such silicone gum include, for example, Toshiba Silicone TSE-200, T
SE-200A and the like may be used, and they may be used alone or in combination of two or more kinds, and are 0.01 to 10 based on the total amount of the hair treatment agent.
%, Preferably 0.5 to 2.0% by weight. If the blending amount is less than the above range, the comb-passing property and smooth feel to the hair are not sufficiently imparted. On the other hand, if it exceeds this range, the feeling of use is deteriorated due to the viscosity of the dimethyl silicone gum itself.

The polyethylene glycol (ii) has an average molecular weight of 10,000 or more, preferably 10,
000 to 100,000, and 0.1 to 20% by weight, preferably 1.0 to 1% by weight based on the total amount of the hair treatment agent.
Add 0.0 wt%. If the blending amount is less than this, the elongation at the time of application is poor and the finished product lacks a moist feel. On the other hand, if it exceeds this range, the performance of the dimethyl silicone gum is impaired and the comb-passing becomes poor. Also,
When the average molecular weight is less than 10,000, the elongation during coating is poor and the finished product lacks a moist feel. In the present invention, in order to further improve the moist feeling and suppleness of the finish, it is preferable to further incorporate at least one of the cationic polymers represented by the formulas [II] and [III]. N ² in the cationic polymer represented by the formulas [II] and [III] is 1,250 to 1,75
0 and n ³ are preferably 1,500 to 2,500, n ⁴ is preferably 1,500 to 2,500, l is 0 and m is preferably 1. Typical examples of such a cationic polymer include, for example, Marcoat 100 (US Merck, Inc.) and Marcoat 550 (US Merck, Inc.).
More than one kind may be used in combination, and the total amount of the hair treatment agent is 0.
01-5.0% by weight, preferably 0.05-2.0% by weight
Mix. If the blending amount is less than this, the finished product will lack moistness and flexibility. On the other hand, if it exceeds this range, a sticky feeling is given.

The hair cosmetic composition of the present invention can be produced by mixing and emulsifying desired components by a conventional method,
It can be in the form of emulsion, blowing agent, hair rinse, hair treatment, hair mousse and the like. In addition, if necessary, the hair cosmetic composition of the present invention may further contain cyclic silicone, triglyceride, ester oil, oil components such as waxes, colorants, fragrances, phosphoric acid, citric acid, etc. within a range that does not impair the performance. A pH adjusting agent, a pyrrolidonecarboxylic acid salt, a humectant such as lactic acid, water, a solvent such as ethanol, an antistatic agent such as a cationic activator, and an ultraviolet absorber can be added.

EXAMPLES Next, the present invention will be described in more detail with reference to Examples and Comparative Examples. In addition, the compounding amount in the examples and comparative examples means% by weight. Examples 1 to 4 and Comparative Examples 1 to 5 The components shown in Table 1 were mixed and stirred by a conventional method to obtain a milky hair rinse. The following items were evaluated using these. The results are shown in Table 1.

(Evaluation Method) The test samples were evaluated by the following methods. Elongation at the time of application: Sensory evaluation by actual use by 5 professional panelists (female in their 20s) ○: Elongation at application is good. X: Poor elongation during application. Feeling at the time of finishing: Sensory evaluation by the actual use of 5 professional panelists (female in their 20s) ◎: Good moisturizing at the time of finishing, giving a supple feel. ○: Good moist feeling when finished. X: Poor feeling when finished. Comb resistance after drying: 2 g of dried hair treated with each test treatment agent was attached to a rheometer (manufactured by Fudo Kogyo Co., Ltd.), and the maximum force applied to the rheometer when passing through the comb was measured. The value was calculated based on the following formula. Comb resistance (%) = (after treatment / before treatment) x 100 Number of cuts: Number of cuts after 7,200 combings (about 2g)
Hair bundle, 119 untreated hairs) Overall evaluation: Good: Good spread during application, good combability and feel when finished. X: Elongation during application is poor, combability is poor, or feel during finishing is poor.
