Mild foaming cosmetic remover composition

The present invention relates to a cosmetic composition for cosmetic removal by a non-spray pump foaming dispenser which is advantageously dispensed into a permanent foam.

An important part of the beauty market is for the removal of cosmetic products. The removal of eye shadow, mascara, blush, lipstick and fluffy pigments is a daily problem for many women. This problem has been solved by formulations which may comprise materials which are acted upon by solvents or by emulsification, for example in the form of O/W creams, gels, oils or flakes. Recently, cosmetic remover compositions utilizing pump foam dispensers have been marketed that allow people to conveniently use in showers or baths (i.e., with wet hands) and dispense the product as a foam to quickly apply to the skin. Do not drip.

The foam is produced by passing the composition through a screen material (which may be a porous material such as a sintered material, a wire (plastic or metal) mesh screen or the like). Preferably, two screens are used.

Suitable mechanical dispensers are described in U.S. Patent No. 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. No. 4, 184, 615 (Wright), U.S. Patent No. 4,598,862 (Rice), U.S. Patent No. 4,615,467 (Grogan et al.), and U.S. Patent No. 5,364,031 (Tamiguchi et al.). All such patents are incorporated herein by reference.

A preferred foamer is a F5L foamer pump head manufactured by Daiwa Corporation of Tokyo, Japan. The foam stability study and pumping ease study described in Example 1 were carried out using this foamer. The F5L device has the following features: mesh size: 255 mesh (upper) / 200 (lower)

Volume / 1 press: 0.95g

Other suitable foaming dispensers can include a squeeze foamer. Squeeze foamer packaging is well known and is exemplified by the disclosure in the following patents incorporated herein by reference. U.S. Patent No. 3,709,437 (Wright, issued January 9, 1973); 3,937,364 (Wright, issued February 10, 1976); 4,022,351 (Wright, issued May 10, 1977); 4,147,306 (Bennett, 1979 4 Issued on March 3; 4,184,615 (Wright, issued on January 22, 1980); 4,598,862 (Rice, issued July 8, 1986); and 4,615,467 (Grogan et al., issued October 7, 1986); and France Patent No. 2,604,622 (Verhulst, published April 8, 1988).

When a squeeze foamer is used, the composition is placed in a container receptacle (plastic squeeze bottle). The container is squeezed by hand, forcing the composition through a foamer ram or other foam generating member, where the composition is mixed with air, followed by a homogenizing member that makes the foam more uniform and controls the consistency of the foam. The foam is then discharged as a uniform, non-pressurized aerated foam.

2. Approximately 0.7 g of sample was dispensed from the F5L pump foamer onto the wet tissue.

3. The foam characteristics were observed after 15 minutes in air at about 20 ° C (RT) and 50% RH under ambient conditions.

4. Rating the foam stability as follows:

+all bubble crashes

++ some bubble crashes

+++ very little bubble crash

(3). Foam stability on dry make-up foundation

1. On a polypropylene plastic plate, 0.2 g of foundation (Shiseido MAQUILLAGE Lasting Liquid UV, Ochre 10 All Season Type available from Shiseido, Tokyo, Japan) was applied to a uniform square pattern of 1.5 cm X 15 cm.

2. Allow to dry in air at about 20 ° C (RT) and 50% RH for 10 minutes under ambient conditions.

The liquid cleaning product is used to fill the container while leaving an air layer. It was sealed using a F5L foamer pump head manufactured by Daiwa Corporation (Tokyo, Japan). Depress the pump and observe if the foam is dispensed. If foam is dispensed, the ease with which the pump dispenses foam is rated as "OK." If no foam is dispensed (eg, only liquid is dispensed), the ease with which the pump dispenses foam is rated as "NG."

(5) Moisture test:

2. Apply approximately 3 g of a single test sample to the right forearm of each member.

3. Rinse with tap water for a few minutes at ambient temperature.

4. Dry with a paper towel, then use each member's full score of 5 to assess the level of moisturizing, and then calculate the sum of all levels.

5. Use approximately 3 g of the comparative test sample on each member's left forearm.

6. Alternatively, appropriate instrumental analysis can be used to compare skin moisturization between samples. All instrument evaluations will be performed after the 30 minute acclimation period. Record indoor humidity and temperature data and include them in the final report. Instrument measurements can be taken at some or all of the following time points: 0, 1, 2, 4, 6, 8, and 24 hours after application of the product. Instruments to be used in this scheme may include, but are not limited to, ServoMed evaporometers with EP1 or EP2 probes (SeroMed AB, Stockholm, Sweden), Corneometer CM820 (COURAGE+KHAZAKA electronic GmbH, Cologne, Germany), with MT-8C The probe's Skicon skin hygrometer (IBS CO., LTD., Shizuoka-ken, Japan) and moisture tester (STR-School & Science Technology Resources, Scotts Valley, Ca).

(7) turbidity

For the purposes of the present invention, the acceptability of the clarity or clarity of the formulation can be qualitatively and quantitatively measured using a haze macroscopic assay and a turbidimeter, respectively. Briefly, the macroscopic method involves viewing a visible target through the determined path length of the formulation and determining whether the visible target is identifiable or identifiable. This target can be a line printed on white paper, a set of parallel lines, numbers or letters. The test formulation was placed in a glass beaker so that the height from the bottom of the beaker to the top surface of the formulation was 4 inches. It was determined that the formulation contained no bubbles. A sheet of paper with a visible target is placed under the beaker. The visible target is viewed through the top surface of the formulation. If the visible target appears to be similar to the original target, then the formulation has acceptable clarity and a "qualified" rating. If the visible target appears to be significantly blurred or ambiguous compared to the original target, the formulation has an unacceptable clarity and a "fail" rating.

The turbidity can be quantitatively determined using a turbidimeter (Model DRT-100D) manufactured by Shaban Manufacturing Inc., H.F. Instruments Division, using a 28 mm diameter multiplied by a 91 mm length and having a flat bottom sample colorimetric cell. Samples that are expected to achieve a "qualified" rating from the naked eye method have a turbidity measurement of less than or equal to 105 NTU (standard turbidity unit). Samples that have a "failed" rating from the naked eye method will have a turbidity measurement greater than 105 NTU.

The above description and examples illustrate selected embodiments of the invention. Accordingly, all variations and modifications within the scope and spirit of the invention will be apparent to those skilled in the art.
