Description

Oil-based solid cosmetics

[0001] The present invention relates to an oily solid cosmetic preparation.

[0002] Oil-based cosmetics are easy to use and portable, and are therefore widely used in makeup cosmetics such as lipstick, lip gloss, foundation, eye shadow, etc. Their components consist of oily ingredients such as liquid oil, semi-solid oil, and solid oil, powders such as coloring pigments and extender pigments, oily gelling agents, etc., and their properties include liquid, paste, and solid forms, but solid oil-based solid cosmetics are required to have an excellent feel when used, such as being able to spread smoothly on the skin when applied.

[0003] In liquid or paste-like oil-based cosmetics, organically modified clay minerals are used as oil-based gelling agents because of their excellent powder dispersion stability and gel softness (e.g., Patent Documents 1 and 2).In contrast, in oil-based solid cosmetics, organically modified clay minerals have not been used much because they may inhibit the crystallization of solid oils and impair the feel during use.

[0004] In recent years, makeup cosmetics have been required to have a soft focus effect that naturally brightens and reduces the visibility of pores and fine wrinkles so that they do not appear different from the rest of the body. Spherical powders such as nylon are used as ingredients that have this soft focus effect, but when spherical powders are blended into oil-based solid cosmetics, they can sometimes cause a dry feeling after application or reduce the feel when applied.

The HLB value of the nonionic surfactant is not particularly limited, but is preferably in the range of 1 to 8, whether used alone or in combination.The HLB (Hydophile-Lipophile Balance) in the present invention is an index showing the balance between hydrophilicity and lipophilicity, and is calculated by the following formula (1) proposed by Oda and Teramura et al. HLB = (Σ inorganic value / Σ organic) × 10 ... (Formula 1) Here, Σ inorganic value / Σ organic is called IOB (Inorganic-Organic Balance), and can be calculated by integrating the "inorganic value" and "organic value" of atoms and functional groups constituting an organic compound such as a surfactant, based on the "inorganic value" and "organic value" set for each atom and functional group (see "Organic Conceptual Diagram - Fundamentals and Applications" by Yoshio Koda, pp. 11-17, Sankyo Publishing, 1984).

[0081] The results shown in Tables 1 and 2 indicate that the oil-based solid cosmetics of Examples 1 to 39 were superior to the oil-based solid cosmetics of Comparative Examples 1 to 10 in terms of the "soft focus effect," "secondary adhesion-free effect," "non-drying feeling," "smooth feel in use," and "ease of edging." On the other hand, the results for the comparative examples in Table 3 were as follows. Comparative Examples 1 and 2, which incorporated a wax with a melting point of 70°C or lower instead of component (E) the wax with a melting point of 70 to 110°C, were difficult to mold into a stick shape, and although they were excellent in the "soft focus effect" and "non-drying feeling," they lacked the "secondary adhesion-free effect," "smooth feel in use," and "ease of edging," and therefore were unsatisfactory. Comparative Example 3, which did not contain component (A) the silicone film-forming agent, failed to provide satisfactory results in the "soft focus effect," "secondary adhesion-free effect," and "non-drying feeling." Comparative Example 4, which did not contain component (B) an organically modified clay mineral, and Comparative Example 5, which replaced it with kaolin, a clay mineral that was not organically modified, failed to provide satisfactory results in terms of "non-dryness" and "smooth feel when used." Comparative Example 6, which did not contain component (C) a non-plastic spherical powder having an average particle size of 0.5 to 50 μm, failed to provide satisfactory results in terms of "soft focus effect," "secondary adhesion-free effect," and "smooth feel when used." On the other hand, Comparative Example 7, which replaced component (C) a non-plastic spherical powder having an average particle size of 0.5 to 50 μm with synthetic phlogopite having an average particle size of 5 to 8.5 μm, failed to provide satisfactory results in terms of "soft focus effect," "smooth feel when used," and "ease of edging." Comparative Example 8, which replaced component (C) a non-plastic spherical powder having an average particle size of 0.5 to 50 μm with dimethicone / vinyl dimethicone crosspolymer, failed to provide satisfactory results in terms of "soft focus effect," "secondary adhesion-free effect," "smooth feel when used," and "ease of edging." In Comparative Example 9, in which non-spherical crystalline cellulose with an average particle size of 20 μm was blended instead of component (C), a spherical powder of a non-plastic material with an average particle size of 0.5 to 50 μm, satisfactory results were not obtained in terms of the "soft focus effect," "smooth feel in use," and "ease of edging."In Comparative Example 10, which does not contain component (D), a semi-solid oil at 25°C, satisfactory results were not obtained in terms of "absence of dryness," "smooth feel when used," and "ease of edging."

The solvent was then distilled off by heating under reduced pressure. Methyl trimethicone was added to adjust the concentration to 30%, and the mixture was then filtered to obtain a methyl trimethicone solution of a crosslinked organosilicon resin.
