Claims38
A solid water-dispersible powder composition of matter comprising at least one sugar, at least one polysaccharide, at least one surfactant and at least one cosmetic lipophilic active ingredient which comprises at least one cosmetic oil or is dissolved in at least one cosmetic oil,
- wherein the composition comprises a plurality of micrometric particles each comprising a plurality of lipophilic nanospheres with an average size in the range of about 50 nm to about 900 nm, the at least one cosmetic lipophilic substance is contained in the micrometric particles and is distributed inside and/or outside the lipophilic nanospheres at predetermined proportions,
- wherein the composition has an encapsulation capacity of the at least one cosmetic lipophilic active ingredient of 70-98% (w/w) relative to the weight of the oil component, and
- wherein the size of the lipophilic nanospheres is substantially maintained upon dispersion of the powder composition in water,
- thereby providing an improved topical and/or dermal delivery of the at least one cosmetic lipophilic active ingredient.
