Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel cosmetic composition, and more particularly to a cosmetic composition which spreads well during use, is easy to spread evenly throughout, and gives a smooth feeling of use.

[0002]

2. Description of the Related Art Creamy cosmetics such as night cream, hair treatments, conditioners, etc.
Most of them are highly viscous in terms of their commercial value, but when used, they do not spread well and do not spread evenly to the skin and hair, so they are usually water-soluble polymer compounds and highly polymerized addition of ethylene oxide Nonionic surfactants. Agents are used.

However, when these are compounded, the elongation is improved, but the composition as a whole becomes soft, and inevitably the product quality is poor. Also,
For low viscosity cosmetics such as emulsions and hair rinses,
When it was dripped into the hand, it could run off from the palm, and it was difficult to spread it all over the body.

[0004]

Under the circumstances described above, the present invention provides a cosmetic composition which has good elongation during use, is easy to spread throughout, and has a smooth feeling of use. It was made for the purpose.

[0005]

Means for Solving the Problems As a result of intensive studies to develop a cosmetic material having the above-mentioned preferable properties, the present inventors have found that a specific monoester and diester which are liquid at a temperature of 20 ° C. are contained in a predetermined ratio. It has been found that the object can be achieved by a cosmetic containing a mixture of a predetermined amount of the mixture, and the present invention has been completed based on this finding.

That is, the present invention provides (A) a general formula R ¹ COOR ² (I) (wherein R ¹ is a linear or branched alkyl group, alkenyl group, hydroxy group having 1 to 25 carbon atoms). An alkyl group or a hydroxyalkenyl group, R ² represents a linear or branched alkyl group having 1 to 23 carbon atoms, an alkenyl group,
A liquid monoester represented by a hydroxyalkyl group or a hydroxyalkenyl group) at a temperature of 20 ° C., and (B) a general formula R ³ OOC- (CH ₂ ) _n —COOR ⁴ (II) (wherein R ³ and R ⁴ is a linear or branched alkyl group having 1 to 19 carbon atoms, an alkenyl group, a hydroxyalkyl group or a hydroxyalkenyl group,
They may be the same or different and n is 0.
Or an integer of 1 to 6), a mixture of liquid diesters at a temperature of 20 ° C. in a weight ratio of 2: 8 to 8: 2, and a mixture of 0.05 to 10 based on the total weight of the cosmetic.
The present invention relates to cosmetics formulated by weight percent.

In the cosmetic of the present invention, a monoester represented by the general formula R ¹ COOR ² (I) (R ¹ and R ² have the same meanings as described above) and a general formula R ³ OOC- (CH ₂ ) It is necessary to blend a mixture with a diester represented by _n- COOR ⁴ (II) (R ³ , R ⁴ and n have the same meanings as described above) as an essential component, and the monoester and diester are mixed at a temperature of It must be liquid at 20 ° C. Furthermore, the effects of the present invention are not exhibited even when the monoester and diester are used alone or when either one is extremely large. That is, when the amount of monoester is extremely large, the obtained composition tends to be hard in both the high-viscosity type and the low-viscosity type and hard to extend. Further, when the amount of diester is large, the high-viscosity composition tends to be soft, which is not preferable in terms of commercial value, and for the low-viscosity composition, although dripping from the hand is improved, it is spread throughout the whole. It tends to be difficult.

From these points of view, the mechanism of action of the present invention is that the diester exerts the function of exhibiting disintegration in the high-viscosity type composition and the tackiness in the low-viscosity type composition, while the monoester is effective. It is thought that it gives the function of exerting the stretchability as a whole. It is considered that the combined use of these makes it easier to stretch and spread easily as a whole, so that smoothness is synergistically exhibited. Therefore, in the present invention, the monoester represented by the general formula (I) and the diester represented by the general formula (II), which are liquid at a temperature of 20 ° C., must be used in combination. A ratio of the monoester represented by the general formula (I) and the diester represented by the general formula (II) in a weight ratio of 2: 8 to 8: 2, preferably 4: 6 to 8: 2. It is necessary to mix in.

The blending amount of the mixture of the monoester and diester in the cosmetic of the present invention is selected in the range of 0.05 to 10% by weight, preferably 0.1 to 7.0% by weight based on the total weight of the cosmetic. Be done. If the amount is less than 0.05% by weight, the effect of the present invention is not sufficiently exhibited, and if the amount is more than 10% by weight, stickiness is caused and the effect tends to be lost.
