Description

Makeup Removal Cosmetic Composition {MAKE-UP REMOVER COSMETIC COMPOSITIONS}

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

Products used to remove makeup are an important part of the cosmetics market. Removing pigments in eyeshadows, mascara, blushes, lipsticks and face powders is a daily problem for many women. This problem has been solved through formulations that may include materials that are manipulated by solvent or emulsification. However, such cleansers often have the disadvantage that they must be separated from the water in order to function effectively and the phases do not separate. It would be convenient for people to use an effective makeup remover during a shower or bath, ie using wet hands. Surprisingly, formulations comprising blends of certain proportions of non-saccharide polyhydric alcohol fatty acid triester (s) and saccharide alcohol fatty acid tetraester (s) blended with oil have no problem of phase separation and reduced makeup removal efficiency, It has been found that the makeup is effectively removed, for example, under wet conditions using wet hands.

US Patent Publication No. 2005/0180942 (Shimizu et al.), Published August 18, 2005, describes a cleansing composition containing nonionic surfactants selected from various glycerol fatty acid esters in an oil base and having specific IOB values. The formulation has been reported to be resistant to phase separation.

US Patent Publication No. 2004/0136943 (Tomokuni), published July 15, 2004, discloses (A) an oil component, (B) a hydrophilic nonionic surfactant, (C) a lipophilic amphiphile, (D) a water soluble solvent, and (E) A cleansing composition comprising water is described. Reportedly, the composition has an isotropic liquid phase exhibiting a bicontinuous structure. The composition is said to exhibit excellent detergency for removal of both oil stains and water soluble stains, and has a high detergency.

Surprisingly, substantially non-aqueous compositions containing certain proportions of non-saccharide polyhydric alcohol fatty acid triester (s) and saccharide alcohol fatty acid tetraester (s) exhibit excellent in-use properties for the user of the composition. It has been found that it is very effective in removing makeup under wet or humid conditions.

IOB value:

As used herein, the term "IOB (inorganic / organic balance)" means an index representing the hydrophilic-hydrophobic balance, and in the present invention, IOB = [inorganic value] / [organic value]. Incidentally, inorganic and organic values can be determined based on Organic Conceptional Diagram (FUJITA, Makoto: "Prediction of Organic Compounds and Organic Conceptional Diagram", Kagaku no Ryoiki (Fields of Chemistry), 11 (10), 719-725 (1957)].

In the present invention, it is important to regulate the IOB of the mixture of PEG fatty acid ester components. The mixed IOB may preferably be in the range of 0.6 to 1.15, more preferably in the range of 0.75 to 1.0. If the mixed IOB is less than 0.6, the water detergency is weakened indicating stickiness. Therefore, a mixed IOB of less than 0.6 is undesirable. If the mixed IOB exceeds 1.15, phase separation or turbidity may appear, resulting in poor appearance and makeup removal efficiency, and therefore, a mixed IOB greater than 1.15 is undesirable.

Appropriate mixed IOBs can be determined by adjusting the proportion of PEG fatty acid ester component or other surfactant such that the entire system is not cloudy at about 30 ° C. Formulas based on the proportions of specific IOBs and individual components in the selected mixing ratios are thus used using the following formulas where a, b, c represent individual PEG fatty acid ester components or other surfactants a, b and c. (Formula below can be used for more complex surfactant blends through expansion in a similar manner):

Mixed IOB = {wt% of IOB (a) x a + wt% of IOB (b) x b + wt% of IOB (c) xc} / {wt% of a + wt% of b + wt% of c}

To evaluate makeup removal efficacy in a series of blends of (s), they were prepared according to Tables 1 and 2, respectively, using the following procedure. The methodology of the make-up removal (MUR) test involves the following procedure. Bio Skin Plate (e.g., BEAULAX, Co. Ltd., Tokyo, Japan) samples were cut into three pieces of 4 cm pieces. The base color for each piece was measured twice using Minolta spectrophotometer CM-2002. A 0.0080 g amount of lipstick was applied to each piece of bio skin plate sample in a 3 cm diameter circle. After 5 minutes, the color of the lipstick was measured with a spectrophotometer and then washed with water. Next, 0.2 ml of test sample solution was applied to the lipstick circle. The sample piece was then rubbed 10 times counterclockwise and then rubbed 10 times counterclockwise using a finger. Rinse for 30 seconds using tap water at about 37 ° C. The color of the lipstick stain was then measured again after 5 rinses. The measurement was then converted to color change percentage. The average of three replicates was used. Test formulations and results are shown in the table below.

Based on the results shown in Tables 1 and 2, it is clear that the samples of the invention are very potent when compared to the corresponding comparative samples.

Test procedure of the examples described in the table:

Samples were prepared by mixing 10 g of the formulations of Tables 1 and 2 with 3 g of water, where the test conditions simulated makeup removal conditions using wet hands. The MUR test is described in the previous section.

Preparation procedure of the embodiment described in the table:

The formulations of Tables 1 and 2 were prepared as follows:

The components were blended together to form the oil phase shown as phase A in the table. Once the oil phase was well blended, the surfactant phase indicated as phase B in the table was added to the bulk. After good mixing, water and methylgluset-10, finally indicated as phase C, were added to the bulk blend with continuous mixing until the bulk blend was homogeneous and clear.

The above description and examples illustrate selected embodiments of the invention. In light of this, modifications and variations will be suggested to those skilled in the art, all of which are within the scope and spirit of the invention.
