Abstract
Use of a polyamino polymer to inhibit the light-induced peroxidation of lipids, particularly inhibition of the photo-peroxidation of lipids induced by nanopigments. The invention also relates to the use of a polyamino polymer to inhibit the light-induced peroxidation of proteins. This property of polyamino polymers finds applications in particular in the cosmetics, pharmaceutical, veterinary and agrifood fields.
