Abstract (en)

[origin: WO2006005630A1] The present application relates to a photo­protective composition comprising, in a physiologically acceptable medium: a) at least one aqueous phase, b) at least hydrophilic inorganic nanopigments based on metal oxides, in an amount ranging from 1 to 25% by weight, with respect to the total weight of the composition, c) at least one polyalkylene glycol with a molecular mass of less than 8000 g/mol. Another subject-matter of the present invention is the use of at least one polyalkylene glycol with a molecular mass of less than 8000 g/mol in a photoprotective composition comprising at least one aqueous phase and at least hydrophilic metal oxide nanoparticles for the purpose of reducing the whitening and/or of improving the stability of the said composition (dispersibility of the nanoparticles in the aqueous phase).
