The conditioning composition for self-heating hair of the present invention is excellent not only in improving hair conditioning, but also in ease of use as well as in softness after drying in damaged hair.

Hereinafter, the present invention will be described in more detail.

The present invention provides a conditioning composition for self-heating hair comprising polyethylene glycol, wherein the composition further comprises trihydroxystearin, a surfactant, and silicone.

(1) Polyethylene glycol

The polyethylene glycol is used in the conditioning composition for the self-heating hair by mixing the first polyethylene glycol and the second polyethylene glycol having different molecular weights from each other, and can provide a superior thermal feeling when used alone.

The polyethylene glycol is represented by the following formula (1).

[Chemical Formula 1]

(In the above formula (1), n is 4 to 800.)

More specifically, the first polyethylene glycol is at least one selected from the group consisting of polyethylene glycols having a weight average molecular weight of 600 or less and n of 4 to 12 in the formula (1). The first polyethylene glycol may be included in an amount of 40 to 90% by weight based on the conditioning composition for hair.

The second polyethylene glycol is at least one selected from the group consisting of polyethylene glycol having a weight average molecular weight of more than 600 and n of 13 to 800 in the following formula (1). The second polyethylene glycol may be contained in an amount of 0.1 to 20% by weight, preferably 1 to 10% by weight, based on the hair conditioning composition.

If the content of the first polyethylene glycol and the second polyethylene glycol is out of the above range, the effect of increasing or decreasing the exothermic effect of the composition is insufficient and it is difficult to obtain the conditioning improvement effect on the hair and the feeling of use may be lowered.

 (2) Trihydroxystearin

The trihydroxystearin is represented by the following formula (2).

(2)

The trihydroxystearin is used as a hair and skin conditioning material or as a thickening agent, and more specifically, it can improve the conditioning feeling when applying hair while controlling the viscosity of the conditioning composition for hair and improving stability.

The trihydroxystearin may be included in an amount of 0.01 to 5% by weight based on the conditioning composition for hair. If the content of trihydroxystearin is less than 0.01% by weight, it is difficult to obtain the effect of viscosity control. If the content of trihydroxystearin is more than 5% by weight, the feeling of stickiness may be strong and the feeling of use may be deteriorated.

 (3) Surfactants

The surfactant is used as a hair conditioning agent and antistatic agent. Preferably, the surfactant is a quaternary ammonium salt such as tricetylammonium salt, behenyltrimethylammonium chloride, cetyltrimethylammonium chloride and the like, and stearamidopropyldimethylamine, And at least one cationic surfactant selected from tertiary amines such as dipropylmorpholine lactate and the like. The cationic surfactant may be included in an amount of 0.1 to 10% by weight based on the conditioning composition for hair. If the content of the cationic surfactant is less than 0.1% by weight, it is difficult to obtain an antistatic effect. If the content is more than 10% by weight, the feeling of use may be deteriorated or the stability of the product may become poor.

Further, when a tertiary amine compound is used as the cationic surfactant, a neutralized acid may be further added to neutralize the tertiary amine compound. The neutralized acid is at least one selected from glutamic acid, aspartic acid, citric acid, and acetic acid.

(4) Advanced alcohol

The higher alcohol is at least one selected from higher alcohols having 12 to 22 carbon atoms. The higher alcohol may be included in an amount of 0.1 to 25% by weight based on the conditioning composition for hair. If the content of the higher alcohol is out of the above range, the formulation becomes so stiff that it can not be discharged well in the container, or the feeling of use and deterioration may be deteriorated.

(5) Silicon

The silicon is at least one selected from dimethicone, dimethicone, cyclopentasiloxane, cyclohexasiloxane, phenyl trimethicone, silicone copolyol, amodimethicone, and silicon quaternium. The content of silicon may be from 0.01 to 25% by weight based on the conditioning composition for self-heating hair.

The composition of the present invention may further contain additives well known in the art to maintain basic physical properties and quality, and may include, for example, nonionic surfactants, humectants, fatty substances, wetting substances, fragrances, preservatives, vitamins, And the like, which are conventionally used in the production of hair cosmetics. The additive may be included in an amount of 0.001 to 5% by weight, preferably 0.001 to 1% by weight, based on the conditioning composition for hair to further enhance the exothermic effect.

Hereinafter, the present invention will be described in detail with reference to examples and comparative examples. The scope of the present invention is not limited by the following examples and comparative examples.

< Experimental Example  1> ease of use and Feeling  evaluation

100 women of 20 to 40 years old were selected and the products containing the hair conditioning compositions of Examples and Comparative Examples were used once every two days for two weeks and then evaluated according to the following evaluation criteria. Respectively.

-Evaluation standard

1: very bad, 2: bad, 3: normal, 4: good, 5: very good

Item Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Ease of use 4.2 4.0 3.2 3.1 3.5 3.4 Massage feeling when applying 4.3 3.9 3.4 2.8 3.2 3.5 Thermal feeling when using 4.1 3.8 1.5 3.8 3.7 2.5 Softness when rinsing 4.2 3.8 2.8 2.7 2.7 2.8 Softness after drying 4.0 3.7 2.7 3.4 3.5 3.4 Gloss after drying 4.2 3.7 2.5 3.0 3.0 3.0

As shown in Table 2, in Examples 1 and 2, the thermal sensation and the feeling of massage upon application were superior to those of Comparative Example 1. Particularly, in Example 3 in which the content of polyethylene glycol-220 was exceeded, And the softness after drying showed the lowest value. In addition, it can be seen that Examples 4 and 5 have excellent thermal sensation but have difficulties in providing ease of use and softness to hair.

< Experimental Example  2> Calorimetric evaluation

To evaluate the calorific value of the products of Examples and Comparative Examples, the temperature was measured after mixing with water at 50:50 as in the case of using a conditioner for hair in general. The temperatures of Examples and Comparative Examples were measured and the results are shown in Table 3 below.

Item Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Pre-mixing temperature (캜) 25 25 25 25 25 25 Temperature after mixing (℃) 45 42 28 43 39 33 Rising temperature (℃) 20 17 3 18 14 8

As shown in Table 3, the temperature rise widths of Examples 1 to 2, 4 and 5 were larger than those of Comparative Example 1, and the larger temperature increase width was attributed to an appropriate mixing of polyethylene glycol having a molecular weight exceeding 600 To increase the heating value.

< Experimental Example  3> Combing  evaluation

To evaluate the conditioning efficacy of the products of Examples and Comparative Examples, a combing sensation evaluation experiment was conducted on dried hair using an Instron Model 4465 Test System (Universal Test Machine).

First, a hair tress was made with the virgin hair of an Asian woman purchased from De-Meo Brothers, USA. Then, the hair was washed with an aqueous solution of 10% SLS (Sodium Laureth Sulfate), rinsed with sufficient water, After drying, it was allowed to stand in a constant temperature and humidity room for 2 hours. The bundle of hair was hung on the load cell ring of Instron, and the comb was fixed using a jig, and then the load value was measured when the Instron was operated.

1 g of the same shampoo was applied to the tested hair bundle and rinsed for 30 seconds. Thereafter, 1 g of the composition of Example 1 and Comparative Examples 1 and 2 was applied to the bundle of hair, followed by rinsing for 30 seconds, and then the combing feeling was evaluated Respectively. Three or more hair bundles were prepared for each composition, and the average of the load values was calculated by testing the items at least three times, and then the average load value after the untreated composition of the composition was measured. And the dominance of combing was evaluated.

The condition of the hair bundle was 10 g and the length was 20 cm. The condition of the comb was a comb of a cylinder type matte stainless steel material with a comb having a diameter of 1 mm and a gap of 1 mm between the combs . The Crosshead speed of the Instron was 500.00 mm / min., The load cell was 10.0 kg / Limit Type, and the displacement distance was 200.00 mm.

The percentage change in the average load value after the untreated / treated compositions of the compositions of the above Examples and Comparative Examples was evaluated in terms of percentage (%), and the results are shown in Table 4.

Item
(unit: %) Example 1 Example 3 Comparative Example 1 Average Load Reduction Rate -56 -30 -33

The larger the negative value, the better the combing feeling. Therefore, the test results of Table 4 show that the conditioning effect is superior to that of the composition of Comparative Example 1 in Example 1. In addition, Example 3 showed a lower load value as compared to Example 1 as a composition exceeding the content of polyethylene glycol-220.

As described above, the conditioning composition for self-heating hair according to the present invention is not only excellent in feeling of heat but also easy to use, and can provide softness and gloss after drying.
