Description

[Detailed description of the invention] [Industrial application field] The present invention is a foundation and an eyeliner.

The present invention relates to make-up removers such as mascara, and more particularly to useful make-up removers prepared by dispersing a specific amount of a specific low-boiling point solvent in an aqueous phase containing a polyacrylic thickener.

That is, an object of the present invention is to provide a product that does not irritate the skin or eyes during use, has an excellent effect on removing cosmetics, and is easy to use.

[Prior Art] Conventionally, there are various types of makeup removers, such as lotion type, emulsion type, and oil type. These are called cleansing agents and removers, and they are usually used exclusively for each type of makeup cosmetic.

Generally, lotion-type removal agents contain a surfactant that has a cleansing effect, and use mild nonionic surfactants and amphoteric surfactants that do not cause damage to the skin. On the other hand, oil-type products have a cleaning effect because their main component is a solvent that has a solvent effect, and emulsion-type products mainly have a cleaning effect by dissolving and dispersing them due to the solvent action of oil and water. .

However, recent makeup cosmetics have been developed that have good adhesion to the skin and are resistant to fading due to moisture, sebum, etc., so-called long-lasting makeup products. Therefore, in order to improve the removal effect, it is necessary to increase the amount of alcohol and surfactant, or to mix and use surfactants with relatively little irritation to the skin and high cleaning action, or solvents with strong dissolving power. Various measures have been taken and various considerations have been made.

[Problem that the invention seeks to solve]

As mentioned above, as a result of emphasis being placed on the property that makeup does not easily come off, it is difficult to remove no-carb cosmetics easily, and in light of this, there has been a demand for the development of products with excellent removal effects. . However, the disadvantage of conventional removal agents is that if you try to increase the removal effect, they tend to cause more irritation to the skin and eyes, while if you aim for low irritation, the removal ability will be inferior. Yes, it was an issue.

Therefore, efforts have been made to obtain a makeup remover that does not irritate the skin or eyes and has sufficient removal ability. 57-
7290? , 57-72908 is publicly known, and the applicant of this patent application has further disclosed that specific monoesters, diesters,
An application has already been filed for an invention that uses a low boiling point isoparaffinic hydrocarbon in combination with a specific flukylimidazolinium betaine (Japanese Patent Laid-Open No. 58-206515).

However, although improvements have been made in terms of safety and removal effectiveness, conventional removal agents, especially oil-type and two-layer types consisting of oil and water, all require a large amount of oil, and therefore After use, the product had a feeling of oily film and stickiness, which was undesirable in terms of feeling of use, and there was also a problem in terms of irritation to the skin and eyes, so it was not completely satisfactory.

[Means for Solving the Problems] In view of the above circumstances, the present inventors continued intensive research and found that a polyacrylic thickener was used as a dispersant or stabilizer, and a specific amount was added to the aqueous phase. We have discovered that by stably dispersing a low boiling point solvent, we can obtain an excellent makeup remover that has a sufficient removal effect, does not irritate the skin or eyes, and is easy to use. The present invention was completed.

That is, 1 the present invention is a method of dispersing 2 to 20% by weight of one or more low-boiling point solvents selected from low-boiling isoparaffin hydrocarbons and low-boiling silicone oils in an aqueous phase using a polyacrylic thickener. It relates to a makeup remover characterized by:

The configuration of the present invention will be explained below.

The low boiling point solvent used in the present invention may be any solvent as long as it is acceptable for cosmetics, and is particularly preferably selected from low boiling point isoparaffinic hydrocarbons and low boiling point silicone oils. Low boiling point isoparaffinic hydrocarbons are Isopar,
It is generally known under the trade name Scherzl. This low boiling point isoparaffin preferably has a boiling point of 200 to 300.
It is preferable for the present invention to use a substance with a boiling point of 300°C or higher. It is not suitable for low-boiling point silicone oils as they tend to become undesirable, and low boiling point silicone oils are not suitable for chain or cyclic silicone oils, e.g. Examples include linear dimethylpolysiloxane with a low degree of polymerization, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, etc., and have a boiling point of approximately 250°C.
The following are preferred.

These are useful for the present invention because they do not irritate the eyes or skin, have a light feel without stickiness, and dry quickly because they are volatile.

In the present invention, the above-mentioned low-boiling point isoparaffinic hydrocarbons and low-boiling point silicone oils are appropriately used alone or in combination of two or more types, but the blending amount of these low-boiling point solvents is 2 to 20% by weight in order to obtain the effect. %, preferably 5-15% by weight
is appropriate. Within this range, the removal effect is sufficiently exhibited, and it is also suitable in terms of skin safety, usability, and stability.

The polyacrylic thickener used in the present invention is not particularly limited, and any water-soluble alkali thickening polymer can be used, such as ordinary acrylic acid, methacrylic acid, etc. Polymers, copolymers of acrylic acid, and partially crosslinked acrylic polymers can also be suitably used. Examples include salts, carboxyvinyl polymers, and the like.

These amounts are those normally used in cosmetics, and are not particularly limited, and are determined based on the relationship with other ingredients and the purpose of adjusting texture and viscosity, but in the case of acrylic polymer emulsions. , 1.5 to 10% by weight, and in the case of acrylic polymers, it is about 0.1 to 2% by weight. That is, within this range, the amount is sufficient for the purpose of maintaining uniform dispersion of the low boiling point solvent.

Incidentally, the alkaline agent for neutralizing and thickening the above-mentioned polyacrylic thickener is not particularly limited.
Anything acceptable for cosmetics can be used.For example, inorganic alkaline agents such as sodium hydroxide and potassium hydroxide, basic amino acids such as L-arginine, amines such as triethanolamine, ammonia, etc. can be mentioned. The amount of alkaline agent added varies depending on the type and is not particularly limited, and may be determined depending on the type of polyacrylic thickener, amount used, etc., but generally 0.0
It is in the range of 3 to 2.5% by weight. The alkaline agent may be added by dissolving it in water in advance or by directly mixing it with the polymer.

Furthermore, when implementing the present invention, emollients,
In order to impart a moisturizing effect or to increase the removal effect, liquid oils, ester oils, hydrocarbon oils, ethanol, propylene glycol, etc. are used.
Water-soluble substances such as 3-butylene gellicol and glycerin can be optionally added within a range that does not impair the effects of the present invention. However, it is important to limit the amount of the oil to about 5% by weight or less, as it may cause an oily film feeling or cause clouding and discomfort if it comes into contact with the eyes.

The makeup remover according to the present invention has the above-described structure, and the product form can be a lotion type or a gel type.

If necessary, other components such as polymeric substances, surfactants, humectants, fragrances, preservatives, pigments, antioxidants, beauty ingredients, etc. may be added in small amounts.
