Abstract:
Porous silica complex powder is provided to have an excellent performance in moisturizing and water retention, by adsorbing or collecting pentaerythritol derivatives and higher alcohol or polyol on porous silica. Complex powder is prepared by adsorbing or collecting pentaerythritol derivatives and higher alcohol or polyol containing 16-22 carbons on porous silica. The higher alcohol is 2-octyl dodecanol. The polyol is selected from a group consisting of dipropylene glycol, a sorbitols solution, glycerol, molasses, polyethylene glycol, glucose, propylene glycol, and 1,3-butylene glycol. The pentaerythritol derivatives and the higher alcohol or the polyol are mixed at a weight ratio of 1:0.1-0.6. Further, a particle size of the complex powder is 0.2-50mum, and a pore of the complex powder is 1-50nm.
Abstract:
A composite powder, and a cosmetic composition containing the composite powder are provided to improve water content, moisturizing effect and moisturizing power keeping effect. A composite powder comprises porous silica; and a mixture of a pentaerythritol derivative and water which is adsorbed to and trapped in the porous silica. Preferably the mixture comprises further a C16-C22 alcohol; and/or glycerin. Preferably the pentaerythritol derivative is represented by the formula 1, wherein R is independently identical or different one another and is H, or a C1-C24 saturated or unsaturated and linear or branched alkyl group containing or not containing a hydroxyl group; m is identical or different one another and is an integer of 0-10; and n is identical or different one another and is an integer of 1-10.
Abstract:
Mesoporous silica complex with L-menthol and a method for manufacturing thereof are provided to reduce skin irritation of L-menthol without loss of its useful effects by encapsulating it with the mesoporous silica, so that sebum absorption, skin cooling, promotion of blood circulation and induction of skin alleviation are accomplished. The mesoporous silica encapsulating L-menthol is provided, wherein the mesoporous silica complex has particle size of 1-50 mum, pore size of 7-10 cm and specific surface area of 500-700 m^2/g. The method for manufacturing the mesoporous silica with L-menthol comprises the steps of: preparing mesoporous silica; and mixing the mesoporous silica with L-menthol, wherein the mixing ratio of mesoporous silica and L-menthol is 100:3~60. A cosmetic composition comprises the mesoporous silica with L-menthol.
