Field of the invention The invention concerns a cosmetic composition for removing makeup that is advantageously dispensed by a non-aerosol pump frothing dispenser as a durable foam. 2. History of the technique An important segment of the cosmetics market are products that are used to remove makeup. The removal of eye shadow pigments, mascara, blush, lipstick and face powder is a daily problem for many women. The problem has been addressed through formulations which may include materials that operate by solvent action or by emulsification, for example, O / W emulsion cream, gel, oil or sheet type product formats are available. Recently, makeup remover compositions using a pump frothing dispenser have been introduced to the market to allow people to conveniently use the shower or bath, that is, with wet hands, and dispense the product as foam for quick action. on the skin without dripping.

W02008052956 published May 8, 2008, for Kobayashi et al. , describes a cleaning composition including a mixture of tri-ester (s) of non-saccharide polyhydric alcohol fatty acids and tetraester (s) of fatty acids of saccharide alcohols in a specific ratio and mixed with oil that removes make-up under humid conditions, such as with wet hands without the problem of phase separation and committed make-up removal efficiency.

Surprisingly, a formulation including a mixture of an acyl glycinate (s) and acyl argininate (s) in a specific ratio range, mixed with polyol (s) and water, was found to produce considerable and lasting foam when dispenses in moist skin and also clean and with the expectation of moisturizing the skin, compared with makeup removers.

Non-aerosol foam dispenser A preferred embodiment of the cleaning product according to this invention is a non-aerosol skimmer dispenser containing the inventive composition. The inventive composition is dispensed as a foam and produces a copious and durable foam in contact with moist skin.

A suitable dispenser is mechanical and is generally characterized by a container for storing the composition (preferably a transparent container), a dispensing head defined by a housing containing a pump, and a dip tube for transferring the composition of the container to the dispensing head. The foam is created by requiring the composition to pass through a screening material which may be a porous substance, such as a sintered material, a wire mesh screen (plastic or metal) or similar structures. Preferably, two screens are used.

Suitable mechanical dispensers are described in U.S. Pat. 3,709,437 (Wright), U.S. Patent No. 3,937,364 (Wright), U.S. Patent No. 4,022,351 (Wright), U.S. Patent No. 4, 147, 306 (Bennett), U.S. Patent No. 4, 184,615 (Wright), US Patent no. 4,598,862 (Rice), U.S. Patent No. 4,615,467 (Grogan et al.), And US Patent no. 5,364,031 (Tamiguchi et al.): All of these patents are incorporated herein by reference.

A preferred skimmer is the pump foaming head F5L manufactured by Daiwa Corporation located in (Tokyo, Japan). This frother was used to conduct the foam stability studies and the ease of pumping studies discussed in Example 1. The F5L device has the following characteristics: Mesh size: Mesh 255 (Top) / 200 (Bottom) Air / liquid ratio: 9.5 / 1 Volume by 1 pulse: 0.95 g Other suitable skimmers may include shrink skimmers. Compression skimmer packages they are well known as exemplified by the descriptions in the following patents which are incorporated herein by reference. U.S. Patent Nos: 3,709,437, Wright, issued January 9, 1973; 3,937,364, Wright, issued February 10, 1976; 4,022,351; Wright, issued on May 10, 1977; 4, 147, 306, Bennett, issued April 3, 1979; 4, 184, 615, Wright, issued January 22, 1980; 4,598,862, Rice, issued July 8, 1986; and 4,615,467, Grogan et al., issued October 7, 1986; and French Patent 2,604,622, Verhulst, published April 8, 1988.

When shrinking skimmers are used, the composition is placed in the container reservoir (plastic compression bottle). Compressing the container by hand forces the composition through a foaming head, or other foam producing medium, where the composition is mixed with air and then through a homogenizing medium that makes the foam more homogeneous and controls the consistency of the foam. The foam is then discharged as a non-pressurized, uniform aerated foam.

The example is for illustrative purposes only and is not intended to limit the invention in any way. The physical test methods are described below: Except in the operational and comparative examples, or where otherwise explicitly indicated, all figures in this description that indicate quantities or proportions of materials or conditions of reaction, physical properties of materials and / or use are to be understood as modified by the word "approximately".

Seal with a F6L pump foaming head manufactured by Daiwa Corporation (Tokyo, Japan). Press the pump and observe if foam is dispensed. If foam is dispensed, qualify the dispensing facility of the pump as "OK". If it is not dispensed (for example, only a liquid is dispensed), qualify the facility to foam the pump as "NG". (5) Moistening test: 1. Mount a panel of trained people. 2. Put approximately 3 g of a test sample on the right forearm of each panelist. 3. Rinse under running water at room temperature for a few minutes. 4. Dry with a towel, then qualify the moisturizing sensation using a maximum score of 5 points per panelist, then add all the qualifications. 5. Repeat using approximately 3 g of the comparative test sample on the left forearm of each panelist. 6. Alternatively, a suitable instrumental method can be used to compare the skin wetness between the samples. All instrumental evaluations will be taken following an acclimatization period of 30 minutes. The interior humidity and temperature data will be recorded and included in the final report. Instrumental measurements can be taken at some or all of the following points in time: 0, 1, 2, 4, 6, 8 and 24 hours after product application.

The ambient temperature will be maintained at 68 ° F to 77 ° F (20 ° C to 25 ° C) and 30% to 40% relative humidity. Moistening will be defined as an average change from the baseline (visual dryness or skin hydration). (6) Procedure to prepare the examples illustrated in Table 1: 1. Dissolve Amisafe in Amilite GCK-12K at 80 ° C (Phase 1) until the solution is clear. 2. Mix water and glycerin at 80 ° C until it was homogenous (Phase 2). 3. Add Phase 1 to Phase 2 at 80 ° C and mix. 4. Add NONSOUL LK-30 at 80 ° C and mix. 5. Add Amphitol, Mydol12 and mix well. 6. Cool to 35 ° C. (7) Turbidity For the purposes of this invention, the acceptability of formulation transparency or clarity can be measured qualitatively and quantitatively using a visual method of turbidity determination and a turbidimeter, respectively. Briefly, the visual method involves observing through a determined stretch of the formulation a visual objective and determining whether the visual objective is readable or recognizable. This objective can be a straight line, a set of parallel lines, a number or a letter printed on white paper.

Place the test formulation in a glass laboratory beaker, so that the height of the bottom of the lab beaker to the top surface of the formulation is four inches. Make sure the formulation is free of bubbles. Place the piece of paper with the visual objective under the laboratory glass. Look through the upper surface of the formulation to the visual objective. If the visual objective appears similar to the original, the formulation is of acceptable clarity and receives a "pass" rating. If the visual objective seems significantly nebulous, or is out of focus, compared to the original objective, the formulation is of unacceptable clarity and receives a "failure" rating.

The turbidity can be determined quantitatively by a Turbidimeter, model DRT-100D, manufactured by Shaban Manufacturing Inc, H.F. Instruments Division using a sample tube 28 mm in diameter by 91 mm in length with a flat bottom. It is expected that samples that receive a "pass" rating from the visual method will have a turbidity measurement less than or equal to 105 NTU's (Nephelometric Turbidity Units). Samples that receive a "failure" rating of the visual method will have a turbidity measurement greater than 105 NUT's.

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