摘要:
Provided are personal care compositions comprising (A) voided latex particles comprising (i) at least one core polymer comprising polymerized units derived from monoethylenically unsaturated monomers containing at least one carboxylic acid group, and non-ionic ethylenically unsaturated monomers, and (ii) at least one shell polymer comprising polymerized units derived from non-ionic ethylenically unsaturated monomers, and polyethylenically unsaturated monomers, and (B) pigment grade inorganic metal oxide particles, wherein the voided latex particles contain a void and have a particle size of from 400 nm to 800 nm. Also provided are methods for lightening skin tone comprising topically administering such compositions to the skin, and methods for improving visible light scattering of a composition including a pigment grade inorganic metal oxide particle comprising adding to such composition a voided latex particle.
