  • Patent number: 10525433
    Abstract: A process for preparing nanocapsules having a core-shell structure, comprising: (a) preparing an oil-in-water emulsion by emulsification of an oily phase that comprises a core material, in an aqueous phase, under high shear forces, wherein one or both of the oily phase, and the aqueous phase comprises a sol-gel precursor; (b) subjecting the emulsion obtained in (a) to a high pressure homogenization to obtain a nano-emulsion; and (c) applying conditions for hydrolyzing and polycondensing the sol-gel precursor to obtain nanocapsules having a metal oxide shell encapsulating the core material, said nanocapsules have a particle size distribution of: d10=10-80 nm, d50=30-200 nm, and d90=70-500 nm, in diameter. The invention also relate to nanocapsules having the above particle size distribution and to composition comprising the nanocapsules.

  • Publication number: 20190015369
    Abstract: The present disclosure relates to methods of treatment of acne in a patient in need thereof, comprising the concomitant once daily topical administration of from about 20 w/w to about 10% w/w of solid particulate benzoyl peroxide (BPO) and from about 0.01% w/w to about 0.1% w/w of solid particulate all trans retinoic acid (ATRA) for a period of up to 3 months, wherein the side-effects of the two actives are medically acceptable and wherein the therapeutic effect of BPO and ATRA is superior to the effect of each active administered alone. The concomitant administration may be carried out by once daily administration to a patient in need thereof of a single composition or of a first composition comprising BPO and a second composition comprising ATRA from a dual chamber dispenser or from two separate dispensers, mixed before applying on the skin of a patient in need thereof for up to 2 weeks, up to 1 month, preferably up to 2 months and more preferably up to 3 months.

  • Patent number: 8449918
    Abstract: A therapeutic, cosmetic or cosmeceutic composition for topical application, capable of stabilizing an active ingredient and delivering the active ingredient, comprising a plurality of microcapsules having a core-shell structure. The microcapsules have a diameter of approximately 0.1 to 100 micron. The core of each microcapsule includes at least one active ingredient, and is encapsulated within a microcapsular shell. The shell is comprised of at least one inorganic polymer obtained by a sol-gel process, and the shell protects the active ingredient before topical application and is designed to release the active ingredient from the microcapsules following application. The composition is useful in encapsulating active ingredients, such as benzoyl peroxide, that are unstable in other formulation, or are irritating to the skin.
