Problems solved by technology

[0007] The transparent cosmetics described in Patent Document 6 contain ultraviolet absorbers, but in general, the cosmetics applied to the skin are exposed to such substances as sweat secreted from the skin and sea water. Moisture from the external environment comes from various types of moisture inside and outside the coating film, so even if the resin and coating agent used to impart water resistance are highly blended, it is difficult to completely prevent the outflow of UV absorbers, UV scattering agents, etc., and the UV protection effect cannot be avoided reduce

Embodiment

[0104] Next, the present invention will be described in more detail by giving examples. The present invention is not limited in any way by the following examples. Unless otherwise specified, the compounding quantity is mass %.

[0105] In addition, the Example and the comparative example are the example manufactured by the conventional method with the prescription shown in Tables 1-3. Specifically, when an oil thickener is included, it is added to the oil, heated to 80-130°C to dissolve it, and the remaining ingredients (ultraviolet absorber, powder, etc.) are added and dispersed with a homomixer After degassing until it became uniform, it was made to harden at room temperature, and each sample was obtained.

Abstract

An aim of the invention is to provide a transparent composition which has a ultraviolet light protecting effect while maintaining a high transparency and, when contacted with moisture such as water orsweat, the ultraviolet light protecting effect of which is improved compared with the effect immediately after application. A solution to the problem is a transparent composition comprising (a) a ultraviolet light absorber, (b) an oily component having a refractive index of 1.5-1.7, (c) an oily component having a refractive index of from 1.3 to 1.5 exclusive, and (d) a powder having a refractiveindex of 1.45-1.55, wherein the refractive index of an oily component mixture, said mixture comprising the oily component (b) having a refractive index of 1.5-1.7 and the oily component (C) having a refractive index of from 1.3 to 1.5 exclusive, is 1.44-1.56.

Description

technical field [0001] The present invention relates to a transparent composition which is transparent and has a high ultraviolet protection effect, and a transparent cosmetic containing the same as a base. Background technique [0002] Oil-based transparent cosmetics mainly have the advantages of beautiful appearance and finished product appearance with a sense of transparency when applied, so various transparent bases have been studied. [0003] For example, Patent Document 1 discloses a cosmetic using a transparent base having a refractive index of 1.45 to 1.54 consisting of 12-hydroxystearic acid and an oil component. In addition, Patent Document 2 discloses a transparent solid cosmetic composed of 12-hydroxystearic acid, heavy liquid paraffin, and a liquid oily component, and Patent Document 3 discloses a product containing 12-hydroxystearic acid with a hydroxyl value of 120 or less. Transparent liquid oil-based ingredients and transparent solid cosmetics of methylphen...
