The invention is a cosmetic or dermatological formulation, comprising:
(a) at least one oxidation- and/or UV-sensitive active ingredient;
(b) at least one dialkyl naphthalate which is characterized by the structural formula
1
in which R
1
and R
2
, independently of one another, are chosen from the group of branched and unbranched alkyl groups having 6 to 24 carbon atoms; and
(c) at least one lipid with a polarity of at most 30 mN/m.
The present invention also includes method of using the cosmetic or dermatological formulations.
Cosmetic and/or dermatological oil-in-water (O/W) emulsion with a viscosity of 10 to 1500 mPaS, containing a) one or more emulsifiers selected from the group of glyceryl stearate citrate, polyglycerol methyl glucose distearate, triceteareth-4-phosphate, b) a homopolymer or copolymer of the acrylic acid and/or its derivatives as polymeric stabilizer, wherein the total concentration of the sum of emulsifier a) and polymeric stabilizer b) is between 0.01% and 1.5% by weight based on the total weight of the emulsion, and wherein the emulsion is free from fatty alcohols with a chain length of 12 to 20 carbon atoms.
粘度为 10 至 1500 mPaS 的化妆品和/或皮肤剂水包油(O/W)乳液,含有 a) 一种或多种选自柠檬酸硬脂酸甘油酯、聚甘油甲基葡萄糖二硬脂酸酯、三硬脂酸甘油酯-4-磷酸酯组的乳化剂,b) 丙烯酸和/或其衍生物的均聚物或共聚物作为聚合物稳定剂,其中乳化剂 a) 和聚合物稳定剂 b) 的总和浓度为乳液总重量的 0.其中乳化剂 a)和聚合物稳定剂 b)之和的总浓度为乳液总重量的 0.01%至 1.5%(以重量计),其中乳液不含链长为 12 至 20 个碳原子的脂肪醇。
