Problems solved by technology

In addition, in the method of stabilizing the hardness of the gel by using other oil gelling agents such as wax and inulin fatty acid ester, there is also a problem in that bottle fillers, tube fillers, etc. are assumed, and cosmetics are mixed and destroyed. In the case of a gel state, the volatile oil cannot be maintained and oil separation occurs; it is difficult to obtain smooth spreading, and the use feeling is impaired

[0076] Preparation of the cosmetic base includes a method of mixing the above-mentioned (A) component, (B) component, (C) component, and optionally (D) component, powder component, and other components.

[0077] The mixing can be performed, for example, by mixing the oily components ((A) component, (B) component, (C) component, if necessary (D) component, and other oil agents) while heating. a step of mixing; and a step of mixing powder ingredients and other ingredients into the resulting mixture.

[0078] Mixing can be performed using, for example, a three-roll mill, a disperser, a homomixer, and the like.

[0079] The gelation of the cosmetic base can be performed by, for example, a method of cooling the filled cosmetic base to room temperature.

[0080] Examples of the predetermined container include stretchable containers, bottles, tubes, cans, bag containers, and the like.

Abstract

The present invention provides an oily gel-like cosmetic capable of achieving both an easy-to-apply feeling and good makeup retention and storage stability at a high level. The oil-based gel cosmeticcontains (A) a dextrin fatty acid ester having a degree of acylation of 2.0 or larger, (B) a crosslinked silicone elastomer having an alkyl group with 8 to 30 carbon atoms, and (C) a volatile oil.

Description

technical field [0001] The present invention relates to oily gel cosmetics. Background technique [0002] Oil-based cosmetics containing oils, oil gelling agents, and coloring materials are used in various cosmetics such as lipsticks, eyeliners, and concealers. Oil gelling agents are formulated to maintain the gel state of oil-based cosmetics and thicken oils, and known examples include waxes, dextrin fatty acid esters, sucrose fatty acid esters, and inulin fatty acid esters; 12-hydroxyhard fatty acid esters; Metal soaps such as aluminum fatty acid, organically modified clay minerals such as organic bentonite (Bentone), partially cross-linked organopolysiloxane, etc. If the compatibility between the oil gelling agent and the oil agent is poor, separation of the oil agent will occur, and the hardness of the cosmetic product will increase or decrease. Therefore, the oil gelling agent is usually selected according to the oil agent to be blended. [0003] Cosmetics containing ...
