    • The disclosed invention relates to a cosmetic composition containing at least one branched oligo-α-olefin, characterized in that the side chains at one branch point at least are ethyl, propyl or longer branched alkyl chains, the branched oligo-α-olefin being obtainable by oligomerization of a) at least one branched α-olefin containing 5 to 18 carbon atoms, b) at least one linear α-olefin containing 4 to 10 carbon atoms, c) a mixture of a branched α-olefin containing 4 to 18 carbon atoms and a linear α-olefin containing 3 to 18 carbon atoms or d) a mixture of various branched α-olefins containing 4 to 18 carbon atoms and linear α-olefins containing 3 to 18 carbon atoms in the presence of a catalyst selected from the group consisting of organic acids, cationic ion exchangers, silica gels, layer silicates, inorganic acids or Lewis-acid-based catalysts. The specific oligo-α-olefins are distinguished by particularly high spreading power, by an improved sensory impression of the final cosmetic formulation and by particularly good stability in antiperspirant/deodorant formulations.
    • 所公开的发明涉及含有至少一种支链低聚-α-烯烃的化妆品组合物,其特征在于,一个分支点的侧链至少为乙基,丙基或更长支链的烷基链,所述支链低聚-α-烯烃可获得 a)至少一种含有5至18个碳原子的支链α-烯烃的低聚,b)至少一种含有4-10个碳原子的直链α-烯烃,c)含有4-18个碳原子的支链α-烯烃的混合物 原子和含有3至18个碳原子的直链α-烯烃或d)含有4至18个碳原子的各种支链α-烯烃和含有3至18个碳原子的直链α-烯烃的混合物在催化剂存在下,选自 由有机酸,阳离子交换剂,二氧化硅凝胶,层状硅酸盐,无机酸或路易斯酸类催化剂组成的组。 具体的低聚-α-烯烃通过特别高的铺展力,通过改进的最终化妆品制剂的感官印象以及在止汗/除臭剂制剂中特别好的稳定性来区分。
