Anatase titanium dioxide particles with a size of at most 100 nm wherein the particles are at least partially covered with a layer of at least one metal oxide, hydroxide or hydroxide oxide and the particles exhibit a BET specific surface of at least 70 m /g and a relative density of the order of 2.2. A process for preparing the anatase dioxide particles is also disclosed.

A novel silicone gum and the use of a silicone gum such as diphenyldimethicone dissolved in a silicone oil for making a cosmetic of pharmaceutical compositions, particularly dermatological compositions, containing a fatty phase. Anb exemplary silicone oil is phenyltrimethicone. Also contemplated is the preparation of a cosmetic or pharmaceutical composition for skin care, in particular for the face or the body or for hair care.

USE OF A DIPHENYLDIMETHICONE DISSOLVED IN A NON-VOLATILE SILICONE SUCH AS PHENYLTRIME-THICONE FOR MAKING A COSMETIC OR PHARMACEUTICAL, IN PARTICULAR DERMATOLOGICAL, COMPOSITION COMPRISING A FATTY PHASE

The invention concerns a cosmetic composition comprising a specific functionalized organopolysiloxane which is linear or cyclic. Said functionalized organopolysiloxane is used as emollient and/or carrier and/or anti-transfer agent in cosmetic compositions.

Cosmetic composition comprising a functionalized polyorganosiloxane

The invention concerns a method for preparing high purity polyorganosiloxanes with arylalkyl function(s) by: hydrosilylation of a hydrogenopolyorganosiloxane, reagent (SiH), and an aromatic monovinyl compound, reagent (Vi), with simultaneous introduction of reagent (SiH) and reagent (Vi), in a reaction medium containing an inert solvent and a hydrosilylation catalyst; then elimination of the solvent, the possible residual reagents (SiH) and (Vi), and/or hydrogenation, the hydrogenation process being optionally followed by an elimination process (or another elimination process) of the products other than polyorganosiloxanes with arylalkyl function(s). The resulting silicones with arylalkyl function(s) can be used as emollients and/or carriers in cosmetic compositions, or as solubilizing agents and emollients in perfume compositions.

Method for preparing silicones with arylalkyl function(s) by hydrosilylation

The invention concerns a perfume composition comprising a perfume base and a lipophilic solubilizing agent based on at least an organopolysiloxane having according to Hansen solubility parameter the following characteristics: &dgr; London interactions ranging from (8) to (21) (J/cm ) , &dgr; of Keesom interactions greater than 0 and capable of reaching 25 (J/cm ) , &dgr; of hydrogen binding ranging from (0) to (23) (J/cm ) . Said organotrisiloxanes with polar or polarizsable function of formula (I) are used as solubilizing agents and emollients in perfume composition.

Perfume composition using organopolysiloxanes

The invention concerns buccodental formulation characterized in that it comprises at least a thickening agent comprising cellulose nanofibrils, said cellulose nanofibrils being substantially amorphous, having a crystallinity index not more than 50%. The invention also concerns said cellulose nanofibrils as thickening agent and/or flavour enhancer in buccodental formulations.

Buccodental formulation comprising essentially amorphous cellulose nanofibrils

Storage-stable, pseudoplastic free-flowing cosmetic compositions/formulations, for example shampoos, shower and exfoliating gels and hair lotions, comprise a stable and homogeneous suspension, in water, of water-insoluble particulates, and which further comprise at least one anionic surfactant, at least one nonionic or amphoteric cosurfactant and at least one electrolyte, these surfactants being present in such amounts as to impart pseudoplasticity thereto with a yield point of at least 0.2 Pa and constituting spherulites suspended within a lamellar phase.
