Description

Color Cosmetic Removal Compositions

The present invention relates to a color make-up removal composition with improved cleaning effects and sensory properties.

Color cosmetics commonly referred to as "makeups" include mascara, eye shadows, eyeliners, blushes, lipsticks and various foundation bases. Conventional makeups are made of vegetable and inorganic waxes, paraffins, lanolin derivatives and mixtures thereof. These vehicles suspend and bind various colorants.

Makeup compositions are typically highly tacky and water resistant. Cold cream has conventionally been used to remove makeup. Cold cream is an old product from a century ago. The first products were primarily animal and vegetable waxes and oils, typically beeswax and olive oil. Water was later added to the molten beeswax and olive oil. As a result, water evaporated on the skin, causing a "cooling" effect during use. These early products were unstable and perishable. Sometimes, almond oil was used instead of heavy olive oil. Borax was incorporated as a stabilizer. In recent years, there has been a modification of using inorganic oil instead of almond oil and adding rose water and rose oil for the purpose of fragrance.

The problem with using cold creams is that they are difficult to clean with water. After treatment with cold cream, it is necessary to use a cleanser to remove oily residue. Consumers also want to be able to easily wash off the cream on their hands after applying cold cream.

To solve this problem, rinsable cold creams have been developed. They were prepared by replacing the main waxes with inorganic and vegetable oils and increasing the concentration of emulsifiers used. US Pat. No. 5,011,681 (Ciotti et al.) And US Pat. No. 5,160,739 (Kanga) describe exemplary washable cold cream compositions. These patents teach the use of polyalphaolefins and surfactants in emulsion form. However, washable products are still in the development stage, and there is a need for improvements in the cleaning effect and post-cleaning skin feel (called sensory properties).

It is therefore an object of the present invention to provide a color makeup removal composition having improved cleansing properties and good rinsing properties.

Another object of the present invention is to provide a color tonal makeup removing composition having improved skin feeling after washing.

These and other objects of the present invention will be readily apparent from the following summary and detailed description of the invention.

The present invention

(i) 1-50% hydrocarbons,

(ii) 1 to 90% of water,

(iii) 0.0001 to 5% thickener,

(iv) 0.1 to 5% silica

(v) 0.1 to 30% of alkoxylated glyceryl C ₁₂ -C ₂₂ fatty acid esters

It includes, to provide a color makeup removal composition.

Recently, it has been found that alkoxylated glyceryl C ₁₂ -C ₂₂ fatty acid esters are very effective in removing color makeup from the skin. Creams containing these esters are easy to spread on the face and very suitable for massage. Products containing these esters are quickly mixed with the make-up to improve their removal. Moreover, the skin feeling after washing was less slippery and fresh.

Another finding of the present invention is the use of thickeners, in particular polyacrylates, for example carbomers together with silica powder. This combination not only enhances viscosity, but also enhances sensory properties for the skin. This combination rinses quickly and leaves a fresh feeling on the skin.

Based on the results in Table 3, it is demonstrated that various alkoxylated fatty acid esters are effective at delivering good sensory properties (eg good post-wash feeling, good dispersity and freshness). In particular, POE (3) glyceryl triisostearate and POE (5) hydrogenated castor oil triisostearate were effective.
