Problems solved by technology

If the solid oil is reduced to make the oil gel structure weak in order to improve usability at low temperatures, problems such as a decrease in hardness will occur in the temperature cycle test, and storage stability will become insufficient. Therefore, if only by changing the solid The strength of the oil-gel structure is adjusted by the amount of oil, which makes it difficult to balance usability and storage stability

preparation example Construction

[0054] Preparation of the cosmetic base material includes a method of mixing the above-mentioned (A) component, (B) component, (C) component, (D) component, and other components added as needed while heating.

[0055] The mixing method is not particularly limited, and for example, a disperser, a homomixer, etc. can be used. Heating temperature can be set to more than the melting point of (A) component and (B) component.

[0056] The curing of the cosmetic base can be performed, for example, by a method of cooling the filled cosmetic base to room temperature.

[0057] As the specified container, a bottle, a tube, a can, a sachet container, etc. are mentioned.

Description

technical field [0001] The present invention relates to an oily solid cleansing cosmetic. Background technique [0002] In recent years, a large number of make-up cosmetics excellent in long-lasting properties have been developed. Therefore, oil-based cleansing cosmetics with good compatibility with makeup cosmetics (makeup compatibility) (メイクなじみ) are very suitable for makeup removal. Oil-based cleansing cosmetics are generally provided in liquid or solid form. [0003] Liquid oil-based cleansing cosmetics use liquid oil as the main ingredient, and are known to have excellent compatibility with make-up cosmetics and strong cleansing effects. However, since liquid oil-based cosmetics have low viscosity, they tend to drip during use, and rubbing action during use is easily transmitted directly to the skin, causing a strong burden or irritation on the skin. [0004] On the other hand, solid oil-based cleansing cosmetics contain solid oils such as waxes in addition to liquid ...
