Description

  The present invention relates to a gel cleansing cosmetic.

  Cleansing cosmetics are high cleansing bases mainly containing oily ingredients and surfactants, and lotions, oils, creams, emulsions, etc. are marketed. ing.

  However, conventional oil-type and cream-type cleansing cosmetics are highly blended with oily ingredients, so they have a markedly superior effect on makeup removal, while the oil-specific use feeling increases. There's a problem. There is also a problem that the skin after cleansing becomes too dry due to excessive degreasing.

  On the other hand, lotion type and emulsion type cleansing cosmetics are highly formulated with water, so the skin after cleansing will not dry, but in order to fully demonstrate the makeup removal effect, Surfactant must be highly blended and may cause undesired irritation to the skin and ocular mucosa during use. Moreover, since it is a liquid medicine type | mold, there also exists a problem of dripping from skin at the time of application | coating and being inferior to a usability | use_condition.

  In order to solve such problems, gel-type cleansing cosmetics have been studied as a form in which makeup can be removed with a light feeling of use without dripping at the time of application. Specifically, a gel cleansing cosmetic containing a gelling agent, a polyoxyethylene fatty acid glyceryl and a polyhydric alcohol (see, for example, Patent Document 1); a specific ester oil or hydrocarbon oil A gel-type cleansing material containing a polyoxyethylene hydrogenated castor oil-type nonionic surfactant, glycerin, and a specific polymer (see, for example, Patent Document 2); a specific alkyl glucoside, and a liquid oil Gel cleansing cosmetic containing water, a nonionic surfactant and a gelling agent (see, for example, Patent Document 3); a polyglycerol fatty acid ester of a specific HLB, glycerol, and silicone oil , Oil-containing gel cleansing composition (see, for example, Patent Document 4); trimethoxysilylated powder and liquid oil component , A hydrophilic gelling agent, cosmetic for cleansing containing a polyoxyethylene fatty acid glyceryl (e.g., Patent Document 5 references) have been proposed.

  However, based on these attempts, a gel-type cleansing cosmetic can be obtained, but in a system using a gelling agent that has been studied in various ways, an oily component in an amount that sufficiently exhibits the cleansing function. If a surfactant is added, there is a problem that gelation cannot be achieved. Moreover, even if it can be gelled, a sufficient thickening effect cannot be obtained, so that there is a problem that the preparation stability and the feeling of use are inferior. On the other hand, even in gelation using the association properties of surfactants, in order to sufficiently thicken the surfactant, it is necessary to add a high amount of surfactant, which only has an adverse effect on makeup familiarity and lowers the cleansing function. In addition, there is a problem that the feeling of use becomes heavy and the washing is inferior.

  As described above, the conventional gel preparation-type cleansing cosmetics have the disadvantage that, from the viewpoint of formulation, it is impossible to add an oily component or a surfactant in an amount sufficient to exert the cleansing function. The cleansing effect cannot be fully exhibited.

<Evaluation criteria for ease of rinsing (washing off)>
◎: More than 16 out of 20 people feel that there is no slimy feeling and easy to rinse ○: 11 to 15 out of 20 people feel that there is no slimy feeling and easy to rinse Δ: 6 to 10 out of 20 people get wet No sensation and easy to rinse ×: 5 out of 20 respondents said that there was no sliminess and easy to rinse

<Evaluation criteria for makeup stain removal effect>
◎: 16 or more out of 20 respondents with no makeup residue and excellent removal effect ○: 11 to 15 out of 20 respondents with no makeup residual and excellent removal effect Δ: 6 to 10 out of 20 Responded that there was no makeup residue and excellent removal effect ×: 5 or less of 20 people answered that there was no makeup residue and excellent removal effect

  From the results of Tables 1 and 2, the cleansing cosmetics of each example can be sufficiently thickened and gelled as compared to those of each comparative example, and also suppressed liquid separation. Thus, it can be seen that it has an excellent effect on the stability of the formulation that maintains the gel-like form. In addition, it can be seen that there is no dripping at the time of application, it extends smoothly, is familiar with makeup, can be easily washed off, and exhibits an excellent cleansing function.

  On the other hand, in Comparative Example 1 and Comparative Example 3 that do not satisfy the configuration of the present invention, it is understood that a sufficient thickening effect cannot be obtained and a gel-like form is not obtained. Moreover, in Comparative Example 2 and Comparative Examples 4 to 5 that do not satisfy the configuration of the present invention, although a gel-like form can be obtained, liquid separation is recognized and the gel-like form cannot be maintained, resulting in poor formulation stability. Or it turns out that it is inferior to a usability | use_condition and the cleansing function is not fully exhibited. In addition, in Comparative Examples 6 to 7 in which the component (D) or the component (E), which is an essential component of the present invention, is replaced with another component having a thickening effect, a sufficient thickening effect cannot be obtained. It turns out that it does not become a shape form.

  Hereinafter, formulation examples of the gel cleansing cosmetic according to the present invention will be shown. In addition, content is mass%. POE is an abbreviation for polyoxyethylene, and the numerical value in parentheses represents the number of added moles of ethylene oxide.
