摘要:
To provide a low-viscosity water-in-oil emulsion sunscreen cosmetic composition which is extremely excellent in UV protective enhancing effect (as the protective boosting effect of the UV absorption capability thereof) over a broad UV radiation region and has superior feeling in use (smooth feeling, dry feeling, and non-sticky feeling, etc.). A water-in-oil emulsion sunscreen cosmetic composition comprising (a) from 0.01 to 10% by mass of a water-soluble polymer and (b) from 0.01 to 30% by mass of a UV absorbent, and having a viscosity of at most 10,000 mPa·s (as measured with a B-type viscometer at 30° C.), wherein the aqueous phase accounts for at most 45% by mass.
摘要:
The present invention provides a cosmetic that contains glycerin modified on both ends with silicone represented by the following general formula (a). In this formula, R1 denotes a straight chain or branched alkyl group having 1-12 carbon atoms or phenyl group, R2 denotes an alkylene group having 2-11 carbon atoms, m is 10-120, and n is 1-11.The object of the present invention is to provide a cosmetic that contains glycerin modified on both ends with silicone and is superior in terms of the sensation during use and the powder dispersion stability.
摘要:
The present invention provides a dispersion of microparticulate titanium oxide that can generate a natural finish feeling, which includes a feeling of transparency, and has good long-term stability and an excellent UV protective effect in both UVA and UVB regions. The present invention is a dispersion of microparticulate titanium oxide characterized in that the microparticulate titanium oxide with the average major axis of 30 to 100 nm and the average minor axis of 8 to 50 nm is dispersed, by maintaining the average size of dispersed particles to be 80 to 110 nm, in a hydrophobic dispersion medium. In the dispersion of microparticulate titanium oxide, the content of silicone oil relative to the total hydrophobic dispersion medium is preferably 10 to 100 weight %. Furthermore, it is preferable that the dispersion of microparticulate titanium oxide contains a biterminally-siliconized polyglycerin as a dispersant. The dispersion of microparticulate titanium oxide can be preferably contained in a cosmetic.
摘要:
A cholesterol ester clathrate comprising a cholesterol ester included within a hydroxyalkylated cyclodextrin; a hydrous composition comprising a hydroxyalkylated cyclodextrin, a cholesterol ester and water; a hydrous composition comprising a hydroxyalkylated cyclodextrin, a cholesterol ester, a hydrous stabilizer, and water; a hydrous composition comprising a hydroxyalkylated cyclodextrin, a cholesterol ester, a clay mineral, and water; a cosmetic containing a hydrous composition; and processes for making the cholesterol ester clathrate and various hydrous compositions. The cholesterol ester clathrate exhibits an emulsifying effect and the hydrous compositions are excellent in water-holding capacity, hydration properties, and separation stability at a high temperature.
