Description

  The present invention relates to a cosmetic composition for removing makeup having improved efficacy. In particular, the present invention relates to compositions that remove make-up under wet or wet conditions.

  An important part of the cosmetics market is the product used to remove makeup. Removal of eyeshadow, mascara, blusher, lipstick and face powder pigments is a daily challenge for many women. This task has been addressed by formulations containing substances that act by the action of a solvent or an emulsifying action. However, such detergents must be kept away from water so that they function effectively and do not cause layer separation. It would be convenient if a human could use an effective make-up remover during showering or bathing, i.e. wet hands. Unexpectedly, a mixture of non-sugar polyhydric alcohol fatty acid triesters and sugar alcohol fatty acid tetraesters in a certain ratio was mixed with oil, for example under wet conditions like wet hands Thus, it has been found that makeup can be effectively removed without the problem of reduced phase separation and makeup removal effectiveness.

  US Patent Publication No. 2005/0180942 of Shimizu et al., Published August 18, 2005, contains a nonionic surfactant selected from a variety of glycerol fatty acid esters in an oil base. A cleansing composition having an IOB value of is described. This formulation is reported to be resistant to layer separation.

  Tomokuni US Patent Publication No. 2004/0136943, published July 15, 2004, includes (A) an oil component, (B) a hydrophilic nonionic surfactant, (C) a lipophilic amphiphile. A cleansing composition comprising an active substance, (D) a water-soluble solvent and (E) water is described. This composition is reported to have an isotropic liquid phase exhibiting an in-phase structure. This composition is described as exhibiting excellent detergency to remove both oil stains and water soluble stains and high rinsability.

  Unexpectedly, a substantially non-aqueous composition containing non-sugar polyhydric alcohol fatty acid triesters and sugar alcohol fatty acid tetraesters in a certain ratio is effective in wet or wet conditions. It has been found that it is very effective in removing the cap and exhibits excellent use characteristics to the user of the composition.

IOB Value As used herein, the term “IOB (inorganic / organic balance)” value means an index indicating a hydrophilic-hydrophobic balance. In the present invention, IOB value = [inorganic value (inorganic value). )] / [Organic value]. By the way, the inorganic value and the organic value are determined based on Organic Conceptual Diagram (Fujita, Makoto: “Prediction of Organic Compounds and Organic Conceptual Diagram” Chemistry, 11 (10), 19-19).

  In the present invention, it is important to control the IOB value of the mixture of the PEG fatty acid ester components. This mixed IOB value is preferably in the range of 0.6 to 1.15, more preferably in the range of 0.57 to 1.0. When the mixed IOB value is less than 0.6, the property of being rinsed away by water is reduced and mucus is exhibited. Therefore, mixed IOB values less than 0.6 are not preferred. If the mixed IOB value exceeds 1.15, phase separation or turbidity is observed, resulting in a decrease in appearance and makeup removal efficiency, so a mixed IOB value higher than 1.15 is not preferred.

Appropriate mixed IOB values can be determined by adjusting the ratio of PEG fatty acid ester components or other surfactants so that the entire system is not turbid at about 30 ° C. Using the following formula (wherein a, b, c mean individual PEG fatty acid ester components or other surfactants a, b, c), the specific IOB values of the individual components and By calculating based on the ratio at the selected mixing ratio as described above, the mixed IOB value can be obtained. Note that this equation can be extended to more complex surfactant mixtures by extending in a similar manner.
Mixed IOB value = (IOB value of a × weight% a + IOB value of b × weight% of b + IOB value of c × weight% of c) / (weight% of a + weight% of b + weight% of c)
