Embodiment 1 and comparative example 1-4

[0211] Cosmetic compositions for eyelashes (mascara) according to Example 1 and Comparative Examples 1-4 having the following text shown in Table 1 were prepared. The numbers in Table 1 are based on weight percent relative to the total weight of the composition.

[0212] For each of Example 1 and Comparative Examples 1-4, the powder components shown in Table 1 were mixed for about 10 minutes. Then non-powder ingredients (oil, surfactant, etc.) shown in Table 1 were added to the mixture, and mixed together for about 15 minutes to obtain the cosmetic composition for eyelashes.

Abstract

The present invention relates to a cosmetic composition for eyelashes such as a mascara, comprising: - at least one anionic surfactant including 2-amino-2-methyl-1,3-propanediol in combination with a C16-C24 fatty acid; and - at least one film-forming polymer present in the form of particles dispersed in an aqueous phase, wherein the weight ratio of the amount of 2-amino-2-methyl-1,3-propanediol in combination with the C16-C24 fatty acid / the amount of the film forming polymer is 0.01 to 0.3, preferably 0.05 to 0.2, and more preferably 0.1 to 0.15.

Description

technical field [0001] The present invention relates to a cosmetic composition for eyelashes, such as mascara. The present invention also relates to a cosmetic method for making up eyelashes by using the cosmetic composition. Background of the invention [0002] Many mascaras have been developed for improved cosmetic properties. For example WO2008 / 062530 discloses a cosmetic composition for eyelashes in the form of an O / W emulsion comprising soaps such as triethanolamine (TEA)-stearate and 2-amino-2-methyl-1-propanol (AMP )-stearate. However, a cosmetic composition in the form of an O / W emulsion in the above amount has poor cosmetic properties. For example, the soap acts as a plasticizer in the aforementioned cosmetic composition, which hinders the lifting of eyelashes. Furthermore, the TEA and AMP bases in the O / W emulsions cause smudges around the eyes of consumers if they try to wash off the cosmetic composition with just warm water. Therefore, there remains a need ...
