Description

Leave on Hair Conditioning Composition < RTI ID = 0.0 >

The present invention relates to a leave-on hair conditioning composition which is applied directly to the hair without washing, and relates to a hair conditioning composition comprising polyacrylate-13 and a dialkyl carbonate.

Modern people's hair is contaminated by exposure to ultraviolet rays, contact with the surrounding environment such as dust, sebum secreted from hair follicles, and frequent perms, hair dry, dyeing, combing, and the like. Damaged hair, when wet or dry, is hard to handle and difficult to handle, such as hard, stiff, and poorly combed. Therefore, consumers' demands and preferences for conditioning products that improve the appearance and feel of hair and make them easier to handle are increasing day by day. Also, the preference for time-saving and easy-to-use products is even higher.

In general, materials such as surfactants and polymers, silicone conditioning agents, hydrocarbon oils and fatty alcohols have been used as hair conditioning materials.

The prior art contains a gradual zero polyacrylate-13 with conditioning effect, which is a technique for dyeing hair, but it is limited to dyeing and there is no mention of general hair conditioning.

In addition, there is a product that is directly applied to the hair without washing, but it is an oil base type hair conditioner product which uses high viscosity dimethicone gum and low viscosity dimethicone or cyclodimecone among hair cosmetics. Because it is oily base type, But its absorption after use is slow, and there is a stickiness inherent in the oil, which leads to the inconvenience of washing hands.

And a hair conditioning product containing a dialkyl carbonate. However, it has a combing effect and an increase in glossiness, while it is a non-aqueous system which does not contain water and is different from the formulation of the present invention.

Among the hair cosmetics applied directly to the hair without washing, the aqueous hair cosmetics of the water-based emulsion type have a disadvantage in that the smoothness and softness of the hair after use are deteriorated with time have. In addition, there is a problem in that it is difficult to realize a sufficient sense of well-being, softness and luster in severely damaged hair.

In order to solve the above problems, the present invention provides a rib-on hair conditioning composition which is excellent in long-lasting conditioning effect and conditioning effect, has good spreadability upon application to hair, is easy to use because it does not need to be washed, And the like.

In order to achieve the above object, the present invention provides a rib-on hair conditioning composition comprising polyacrylate-13 and dialkyl carbonate represented by formula (1).

 [Chemical Formula 1]

(Wherein R ₁ and R ₂ each represent a C 1 to C 22 A straight or branched, saturated or unsaturated alkyl group or an alkenyl group).

The hair conditioning composition of the present invention has excellent conditioning effect that imparts softness, smoothness, shine and the like to damaged hair, and the conditioning effect lasts for a longer time than the conventional composition. Also, it does not need to be washed, it is directly applied to hair, it absorbs quickly after use, and it is easy to use and carry because there is no sticky or oil on the hand. In addition, when applied to hair, it is excellent in spreadability due to a suitable viscosity and has an excellent effect of not flowing down from hair.

Hereinafter, the present invention will be described in more detail with reference to examples. These examples are only for illustrating the present invention, and the scope of the present invention is not limited thereto. That is, without departing from the spirit and scope of the present invention.

The present invention provides a rib-on hair conditioning composition comprising polyacrylate-13 and a dialkyl carbonate represented by formula (1).

[Chemical Formula 1]

(Wherein R ₁ and R ₂ each represent a C 1 to C 22 A straight or branched, saturated or unsaturated alkyl group or an alkylene group.)

The rib-on hair conditioning composition is characterized in that the polyacrylate-13 comprises 0.01 to 5 wt% of the total weight, and the dialkyl carbonate comprises 0.01 to 10.0 wt% of the total weight.

The dialkyl carbonate improves the dullness of the hair, softens the hair and adds luster to the hair to smooth the appearance of the hair and improve the continuity of the conditioning effect.

The dialkyl carbonate includes any one selected from the group consisting of dimethyl carbonate, diethyl carbonate, diethylhexyl carbonate, and dicaprylyl carbonate, but is not limited thereto.

The polyacrylate-13 is a copolymer formed by polymerizing an acrylic acid, acrylamide, sodium acrylate, and sodium acryloyldimethyltaurate. The polyacrylate-13 is widely used for moisturizing because of its ability to function as an increasing agent. It has excellent emulsifying ability to oil with smooth feeling and can be applied in a wide pH range. In addition, since it is highly water resistant in an underwater emulsion form, it is used as a film agent.

According to an embodiment of the present invention, the thickener polyacrylate-13 may be included in an amount of 0.01 to 5 parts by weight, preferably 0.05 to 3 parts by weight, based on 100 parts by weight of the total composition. If it is added in an amount less than the above range, the viscosity will be lowered and hair spreadability and formulation stability will deteriorate. If it is added in an amount exceeding the above range, the spreadability will decrease and tackiness will increase.

The dialkyl carbonate may be used in an amount of 0.1 to 10 parts by weight, preferably about 0.5 to 5 parts by weight, based on 100 parts by weight of the total composition. When the amount is less than the above range, hair-dressing and conditioning effects are insignificant. If it is added in excess of the above-mentioned range, build-up will occur and deterioration will occur.

Wherein the rib-on hair conditioning composition is a non-washed, leave-on hair conditioning composition.

The compositions of the present invention may contain ingredients well known in the art to maintain basic properties and quality, such as nonionic surfactants, moisturizers, fatty substances, wetting substances, fragrances, preservatives, vitamins, And components conventionally used in production may be included. Specifically, hair repair agents such as keratin and hydrolyzed wheat protein can be used.

In addition, the rib-on hair conditioning composition of the present invention is in the form of an O / W emulsion of conventional hair cosmetics such as hair rinse, hair cream, hair ampoule, hair treatment, etc., . ≪ / RTI >

As shown in Table 3 above, Examples 1 to 6 do not flow down upon application to the hair because they have a high viscosity, which is convenient to use. However, in Comparative Example 1, since the viscosity is very low, it is very inconvenient to use because it flows down on the hair, and in Comparative Example 2, the viscosity is too high, have.

< Experimental Example  2> 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 the above Examples and Comparative Examples were used once a day for 2 weeks and evaluated according to the following evaluation criteria. The results are shown in Table 4, and the results of the comparative examples are shown in Table 5 below.

According to the above Table 4, Example 1 containing 1.0 wt% of polyacrylate-13 had a formulation viscosity comparable to Comparative Example 1 which did not contain polyacrylate-13 and Comparative Example 2 which contained 6.0% of polyacrylate-13 It is suitable, and it is very easy to use by applying to hair. In the case of Comparative Example 1 and Comparative Example 2, the viscosity of the formulation and the degree of smoothness on the hair were evaluated to be extremely low.

As can be seen from the above results, it can be seen that a composition containing polyacrylate-13 gives an appropriate viscosity and affects the hairiness of hair of the composition. And when the polyacrylate-13 is contained in an excessive amount, it has an adverse effect on the viscosity and spreadability.

In addition, Example 1 was evaluated in all items superior to Comparative Examples 3 and 4. It was found that the softening of the hair was reduced and the conditioning effect was reduced as compared with Example 1 containing dicaprylyl carbonate of Comparative Example 3 without dicaprylyl carbonate, Compared with Example 1 containing 2.0% by weight of dicaprylyl carbonate and Example 5 containing 5.0% by weight of dicaprylyl carbonate, Comparative Example 4 showed that the hair was sticky and the conditioning was reduced due to the persistence of softness .

< Experimental Example  3> Combing  evaluation

To evaluate the conditioning efficacy of the products manufactured according to Examples 1 to 6 and Comparative Examples 1 to 4, the wet and dry hair were combed using an Instron Model 4465 Test System Evaluation experiments were conducted.

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.

After 1 g of the hair bundle was applied to the bundles of hair with the compositions according to Examples 1 to 6 and Comparative Examples 1 to 4, the hair bundles were subjected to a massage for 1 minute, and the combing feeling was evaluated by the above-mentioned method. 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 percentages of change in the average load value after the untreated / treated compositions of the above Examples and Comparative Examples were compared and evaluated. The results are shown in Table 6.

Item Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Average Load Reduction Rate -56 -45 -40 -46 -50 -50 -19 -10 -28 -22

(unit: %)

A larger negative (-) value means that the combing feeling is better. Thus, the test results show that Example 1, which contains 1.0 wt% of polyacrylate-13, contains Comparative Example 3, which does not contain polyacrylate- It can be seen that the conditioning effect is dominant over the composition of Comparative Example 4 containing 6.0 wt% of the rate-13.

In addition, the load value of Example 1 was much lower than the load value of Comparative Example 3 in which dicaprylyl carbonate, which is a dialkyl carbonate referred to in the present invention, was excluded and Comparative Example 4 in which dicaprylyl carbonate was excessively contained It can be seen that the use of a suitable amount of dialkyl carbonate, dicaprylyl carbonate, influences combing.

As described above, the rib-on hair conditioning composition of the present invention is excellent in long-lasting conditioning effect and conditioning effect, and does not flow down to a proper viscosity, uniformly spreads on hair, does not become tacky and is directly applied to hair without washing with water It saves time and is easy to use.
