Abstract

PURPOSE:To provide the titled removing agent having sufficient removing performance and free from irritation to the eye and the skin therearound, by compounding a mono or diester having specific C-number, a low-boiling isoparaffin hydrocarbon, an alkylimidazolinium betaine, and water. CONSTITUTION:The titled removing agent contains (A) 10-40wt% (preferably 15-30wt%) of mono or diester having 23-28 (preferably 24-26) carbon atoms (e.g. decyl myristate), (B) 0.5-5wt% (preferably 1-3wt%) of a low-boiling isoparaffin hydrocarbon (e.g. ''Iso-Par''), (C) 0.2-2wt% (preferably 0.4-1.5wt%) of the compound of formula I or formula II (R is 11-17C alkyl), and (D) 30- 95wt% of water. The removing agent is a double-layer liquid or an emulsion, and can remove the durable eye makeup cosmetic easily without irritating the eye mucosa and the skin.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the removal of eye makeup cosmetics such as eyeliner and mascara, and the present invention relates to the removal of eye make-up cosmetics such as eyeliner and mascara. The aim is to provide products that do not cause irritation.

In recent years, emphasis has been placed on the ability of eye makeup cosmetics such as mascara and eyeliner to be resistant to fading due to moisture such as sweat and seawater, and moisture such as sebum.

In order to obtain this function, products such as a non-aqueous type whose main ingredients are a low boiling point isopatefin hydrocarbon and an oil agent, and a skin-forming type whose main ingredients are a synthetic resin emulsicon and water have been put into practical use.

However, as a result of emphasis being placed on the ability to prevent makeup from fading, recent eye makeup cosmetics have had the disadvantage that they are difficult to remove. Therefore, there is an urgent need to develop a removal group for removing such cosmetics. However, the removal group, which has sufficient removal ability, is highly irritating to the eye mucous membranes, skin, etc.
On the other hand, the problem with conventional removal groups is that those that focus on hypoallergenicity have poor removal ability.

As a result of intensive research in view of such problems, the present inventors have succeeded in obtaining an extremely excellent eye makeup removal group that has sufficient removal ability and is not irritating to the eye mucous membranes, skin, etc. And, the present invention was completed.

That is, the present invention comprises 10 to 40% by weight of one or more monoesters or diesters with a carbon Wk of 23 to 2 days, 5 to 5% by weight of a low boiling point isoparaffinic hydrocarbon LL, and % of the general formula 0 (in the formula , R is an alkyl group with carbon Wk 11 to 17), and 112 to 2% by weight of one or more alkylimidazolinium betaines, and 30 to 85% by weight of water.
This eye makeup removal group is characterized by essentially containing the following.

Hereinafter, the configuration of the present invention will be explained in detail. The monoester or diester used in the present invention has 23 to 2 carbon atoms.
The number must be 8, preferably 24-26. If the number of carbon atoms is 22 or less, it is irritating to the eye mucous membranes and skin, and if the number of carbon atoms is 29 or more, the removal ability is poor. These monoesters or diesters include decyl myristate, 2-octyldodecyl 2-ethylhexanoate,
Examples include didecyl adipate, propylene glycol capricate, and cetyl 2-ethyl phosphate. The blending amount of these is 10 to 40% by weight, preferably 15 to 60% by weight. If it is less than 10% by weight, a sufficient removal effect will not be achieved, and if it is more than 40% by weight, it is not pleasant to the touch. The low boiling point isoparaffinic hydrocarbons used in the present invention are commercially available under trade names such as Isopar and Scherzl. Isopar is humble
Oil and Refining Isopuffin made by Kanno Kuni. Shellzuru is an isoparaffin manufactured by Shell Chemical Co., Ltd.The low boiling point isoparaffin preferably has a boiling point of 240°C or less, and its blending amount is [15 to 55 to 5% by weight, preferably 1 to 5% by weight].
It is 3% by weight.

If the blending amount is less than (L5 weight), it will not contribute to the removal effect,
If it exceeds 5% by weight, it is unfavorable in terms of odor. Furthermore, the alkylimidazolinium betaine used in the present invention is represented by the general formula 0% (wherein R is an alkyl group having 11 to 17 carbon atoms), and a 50% aqueous solution of this is: Miranol C2M Conch (Miranol 02
It is commercially available from Mitenol under the names of Miranol G'M ConC, and Miranol G'M ConC. The above-mentioned alkylimidazolinium betaine is a type of so-called amphoteric surfactant, but it does not have irritation to eye mucous membranes or skin,
It also has an excellent cleaning effect on the mouth. The amount of this compound is 1.2 to 2% by weight, preferably 0.4 to 1.5% by weight.
It is. If it is less than 12% by weight, the cleaning action will be insufficient, and if it is more than 2% by weight, it will feel sticky during and after use, so it should be soaked in water. Further, water used in the present invention is blended in a range of 30 to 85% by weight.

The eye makeup removal group according to the present invention has the above-mentioned structure, and has a two-layered liquid-like or emulsion-like appearance. Note that, if necessary, oils, active agents, polymer compounds, fragrances, pigments, preservatives, isotonic agents such as salt, etc. other than the essential constituents of the present invention may be added as appropriate.

Next, the present invention will be explained in detail based on examples. In order to demonstrate the effects of the present invention, a conventional eye makeup removal group was used as a comparative example, and the removal effect and eyelid irritation were compared.
