The invention includes a diester exhibiting improved hydrolytic stability that is an esterification product of a 1-methylheptyl alcohol and a dicarboxylic acid. In some embodiments, the diester is bis(1-methyl heptyl) butanedioate, bis(1-methyl heptyl) nonanedioate and/or bis(1-methyl heptyl) decanedioate. The diester may be natural and/or not sourced from palm. Also contemplated within the scope of the invention are diesters exhibiting improved hydrolytic stability represented by Formula (I):
wherein R1 is chosen from a linear alkyl group containing four to ten carbon atoms. Also included are personal care compositions comprising any of these diesters and methods of preparing a personal care composition using the inventive diesters, and/or methods of altering the tactile impression and/or skinfeel provided to a user by a personal care composition by combining any of the diesters of the invention and at least one personal care component to form a personal care composition; and topically applying the personal care composition to the hair, skin, and/or nails of a user.
本发明包括一种具有更好水解稳定性的二酯,它是 1-甲基庚基醇和二羧酸的酯化产物。在某些实施方案中,二酯是双(1-甲基庚基)丁二酸酯、双(1-甲基庚基)壬二酸酯和/或双(1-甲基庚基)癸二酸酯。二酯可以是天然的和/或并非来自棕榈。在本发明的范围内,还可考虑式 (I) 所代表的具有更好水解稳定性的二酯:
其中 R1 选自含有四至十个碳原子的线性烷基。此外,还包括包含上述任何一种二酯的个人护理组合物,以及使用本发明二酯制备个人护理组合物的方法,和/或通过将本发明的任何一种二酯与至少一种个人护理成分结合形成个人护理组合物,改变个人护理组合物提供给使用者的触觉印象和/或肤感;以及将个人护理组合物局部涂抹到使用者的头发、皮肤和/或指甲上的方法。
