Abstract
The invention provides a cosmetic lipcare and/or lip makeup composition comprising at least one cosmetically acceptable organic liquid medium and a dispersion of a grafted ethylenic polymer, the said polymer being such that, when dispersed in sufficient amount in the composition, the composition is able to form a deposit having a transfer of less than or equal to 35%.
