This invention relates to the use of microgranules comprising destructurized starch in a complexed form as abrasive and/or structuring agents in cosmetic, dermatological, detergent and cleansing formulations.

Bridged polysilsesquioxane based sunscreens prepared as nanoparticles via oil/water microemulsion polymerization, sol-gel polymerizations, or a modified Stober process. Minimized leaching and decreased levels of photo-degradation were achieved with covalent incorporation, with bridged incorporation necessary to ensure isolation of the sunscreen and any photo-products from skin. SPF values of were found to be comparable to existing commercial sunscreens. Furthermore the bridged polysilsesquioxane based sunscreens can be classified as broad-spectrum, and rate from moderate to superior in terms of UVA protective ability.

An oil-gel-form external preparation for skin contains a compound represented by the following General Formula (1), an isomer thereof, and/or a pharmaceutically acceptable salt thereof. A partially cross-linked methyl polysiloxane; allows easy penetration of the compound from the preparation into the skin while enhancing the percutaneous absorbability and improving the intradermal retentivity. ##STR00001##
In the formula, R.sub.1 represents a C.sub.1-C.sub.4 linear or branched alkyl group substituted by a carboxyl group(s), or a C.sub.1-C.sub.4 linear or branched alkyl group substituted by a carboxylic acid ester group(s) having a C.sub.1-C.sub.4 alkyl chain, and R.sub.2 and R.sub.3 each independently represent a C.sub.1-C.sub.4 linear or branched alkyl group.

The invention relates to a process for preparing PCL-comprising microparticles, to microparticles obtainable by said process, to gel hence obtained and to several uses of the gel such as for the preparation of a medicament for treating a skin abnormality or disfigurement, and/or for controlling bladder function and/or controlling gastric reflux and/or for treating erectile dysfunction and/or for treating vocal cords. The gel may also be used for cosmetic applications.

The invention relates to a solid cosmetic composition comprising anhydrous spheroids dispersed in a solid aqueous continuous phase. The invention is also directed toward a process for preparing a solid cosmetic composition according to the invention, and also a process for making up and/or caring for bodily and/or facial skin using a solid cosmetic composition according to the invention. The invention is also directed toward a stick or a solid gel cast in a dish or a pot, and more particularly a lipstick, a foundation, and an antisun stick, comprising a cosmetic composition according to the invention.

A topical composition comprising a Polymer, a high molecular weight hyaluronic acid (HWM HA) and/or its salt, a low molecular weight hyaluronic acid (LWM HA) and/or its salt, and a polyamino acid and/or its salt; and water and a method for identifying a test polymer that forms a micro-mesh structure when combined with such ingredients.

Silica particles having a d50 median particle size of at least 6 μm, a ratio of (d90−d10)/d50 from 1.1 to 2.4, a RDA at 20 wt. % loading from 40 to 200, and a sphericity factor (S80) of at least 0.9, are disclosed, as well as methods for making these silica particles, and dentifrice compositions containing the silica particles.

A composite particle includes a core particle having a pore and fine fibers inseparably bonded to a surface of the core particle. The fine fibers are at least either cellulose nanofibers or chitin nanofibers.

Disclosed are a cosmetic composition having increased skin contact and makeup persistence and a method of manufacturing the same. The method includes: forming a powder continuous phase by rapidly mixing a powder and a film-forming agent; and obtaining a cosmetic composition in which a surface of the powder is compounded with the film-forming agent by heating the powder continuous phase for a predetermined time. In an embodiment, the cosmetic composition is manufactured by the method. In an embodiment, the cosmetic composition includes 5 wt % to 30 wt % of a powder, 0.1 wt % to 10 wt % of a film-forming agent, 10 wt % to 30 wt % of a silicone oil, and 0.1 wt % to 10 wt % of a spherical powder.

It relates to a composition for conditioning keratin materials, comprising (A) a spheric particles of lipophilically modified silica; (B) a medium/solvent, selected from water and alcohol, and (C) at least one conditioning active agent.
