The present invention relates to the use of at least one caprolactam derivative of formula (I) below: in which: n=0 or 1; m=0 or 1; p=0 to 13; R
1
is a linear or branched alkyl radical comprising a number t of carbon atoms of from 1 to 20; subject to the following conditions: (i) when p=0, m=0, (ii) when p=1 and n=1, m=1, (iii) when p=1 and n=0, m=0 and R

20
alkyl radical; with the proviso that the sum of p+t is between 3 and 20, in a composition comprising, in a cosmetically acceptable medium, at least one liquid fatty phase and at least one lipophilic active agent, and containing no dibenzoylmethane-type UV screening agent, as a solvent for said active agent in said liquid fatty phase and/or as an agent improving the solubility of said active agent in the solid fatty phase. The present invention also relates to a composition comprising, in a cosmetically acceptable medium, at least one liquid fatty phase, characterized in that it comprises at least one caprolactam derivative of formula (I) as defined above and in that it does not contain a dibenzoylmethane-type UV screening agent.
本发明涉及使用以下式(I)的至少一种己内酰胺衍生物:其中:n=0或1;m=0或1;p=0到13;R1是包含1到20个碳原子的线性或支链烷基,满足以下条件:(i)当p=0,m=0时,(ii)当p=1且n=1,m=1时,(iii)当p=1且n=0,m=0且R1表示C2-C20烷基;但p+t的总和在3到20之间,在包含至少一种液态脂肪相和至少一种亲脂性活性剂的化妆品可接受介质中,作为所述活性剂在所述液态脂肪相中的溶剂和/或作为改善所述活性剂在固态脂肪相中的溶解度的剂量。本发明还涉及一种化妆品可接受介质中含有至少一种液态脂肪相的组成物,其特征在于它包含上述定义的至少一种式(I)的己内酰胺衍生物,且不含二苯甲酮型紫外线筛选剂。
