Embodiment 1 to 9

[0040] Examples 1 to 9: Samples with different degrees of neutralization (soap:fatty acid molar ratio)

[0041] Various compositions were prepared by mixing the ingredients shown in Table 1 at a temperature range of 70 to 80°C that ensured that all of the potassium hydroxide was consumed in neutralizing a portion of the fatty acids used in the soap.

[0042] The stability of the composition (vanilla) was tested using the following procedure:

[0043] Stability as used herein refers to the ability of the composition to maintain its appearance and macrostructure without phase separation when stored under the following conditions.

[0044] Samples were stored at 4°C, 25°C, 37°C, and 45°C for three months, or at 50°C for one month. For stability measurements, samples were examined at the end of weeks 1, 2, 4, 8 and 12. At the end of the 12th week the samples were observed for appearance and left at 25°C for 24 hours before being re-observed. The results are reported in Table 1...

Abstract

The invention relates to a personal care composition that provides the excellent sensorial of a vanishing cream while ensuring sun protection and good makeup property though incorporation of pigments. The above objects are achieved by selective use of a specific range of mole ratio of soap: fatty acid in the vanishing cream base.

Description

technical field [0001] The present invention relates to personal care compositions. The present invention relates more particularly to personal care compositions which provide a superior feel of a vanishing cream from the high amount of pigments incorporated therein while ensuring sun protection and good cosmetic effectiveness. Background technique [0002] Creams are a very common form of cosmetic vehicle used to deliver actives for personal care benefits. A variety of different types of creams are available, and each type of cream provides different sensory properties. Consumers living in hot, humid climates, or those with oily skin desire personal care products that have unique tactile properties during use. In particular, such products should provide high skin friction and a matte finish when applied to the skin to overcome oily skin feel and greasy skin appearance. The greater the increase in skin friction, the less oily the product will be perceived by the user. Mo...
