Description

1. Field of technology.

The present invention relates to a cosmetic composition for removing makeup, which is preferably sprayed in the form of a resistant foam using a non-aerosol pump foam-forming dispenser.

2. The prior art.

An important segment of the cosmetics market is represented by products that are used to remove makeup. Removing pigment from eye shadow, mascara, blush, lipstick and face powder is a daily problem for many women. This problem has been solved with formulations which may contain substances acting by dissolution or emulsification, for example, product formats in the form of an oil / water emulsion cream, gel, oil or film type are available. Recently, makeup remover compositions sprayed with a pump-shaped foaming dispenser have been introduced to the market in order to provide people with the possibility of convenient use in the shower or bath, i.e. with wet hands, and for spraying the product in the form of foam for quick action on the skin without dripping.

In document UO 2008052956, published on May 8, 2008, Kohauaky c1 a1., A cleaning composition is described containing a mixture of fatty acid triesters (s) and non-sugar polyhydric alcohol and tetraesters (s) of fatty acid and sugar alcohol in a specific ratio and mixed with oil that removes makeup in wet conditions such as wet hands, without the problem of phase separation and reduced makeup removal efficiency.

It was unexpectedly discovered that a composition containing a mixture of acylglycinate (acylglycinate) and acylargininate (acylargininate) in a certain range of ratios, mixed with polyol (polyols) and water, provides an abundant and resistant foam when sprayed onto wet skin and also has a cleansing effect and, like It is expected to moisturize the skin compared to makeup products for comparison. In addition, the product according to the present invention has no ° C problem, which was observed for comparison products and products known from the prior art.

Preferably, the product of the present invention is applied using a bench-top mechanical pump-action metering device that allows foam to be sprayed directly onto hands. Preferably, said pump-type metering device is in a stable position such that a hand or forearm can be used to press the pump device and spray the product. This provides a more hygienic way to cleanse. In addition, an initial dilution with water is not required since the foam can be easily distributed over the skin before rinsing. The product according to the present invention is preferably transparent. In this text, transparency is defined as having a turbidity of less than or equal to 105 NEM (nephelometric turbidity units).

U.S. Patent Nos. 3,709,437, UPDITs Issued January 9, 1973; 3937364, \ Upd. issued February 10, 1976; 4022351, \ UPD1c, issued May 10, 1977; 4,147,306, Weil issued April 3, 1979; 4,146,615, Update 1, issued January 22, 1980; 4598862, Neck issued July 8, 1986, and 4615467, Sgodap e! A1., issued October 7, 1986, and French Patent No. 2604622, Huyigi, published April 8, 1988.

They pressed the pump device and observed whether foam sprayed. If the foam was sprayed, the ease of spraying the foam from the pump device was rated OK. If the spraying of the foam did not occur (for example, only liquid was sprayed), the ease of spraying the foam from the pump device was evaluated as N0.

- 6,027,395 (5) Analysis of the moisturizing effect.

1. Made up a group of trained individuals.

2. About 3 g of one of the test samples was placed on the right forearm of each of the study participants.

3. Washed with tap water at room temperature for several minutes.

4. Wiped dry with a towel, then evaluated the feeling of hydration using the maximum score from each of the study participants, which is 5 points, then summed up all the ratings.

5. The experiment was repeated using 3 g of the reference test sample on the left forearm of each of the study participants.

All instrumental assessments are carried out after a 30-minute period of acclimatization. Humidity and room temperature data are recorded and included in the final report. Instrumental measurements are performed at some or all of the following time points: 0, 1, 2, 4, 6, 8, and 24 hours after application of the product. Instruments for use in accordance with this protocol may include, but are not limited to, the evaporation rate meter §etuoMeb Еuaropte1eg with probe ЕР1 or ЕР2 (§etetomeb AV, Stockholm, Sweden), corneometer СМ820 (СОиКАОЕ + ΚΗΑΖΑΚΑ е1ес1гошс STН, Cologne, Germany) , a skin moisture meter δήίοοη with a probe MT-8С (Ι.Β.δ.

4. Added ΝΟΝδΟυΕ LK-30 at 80 ° C and mixed.

5. Atryo1, Mu4o112 was added and mixed thoroughly.

6. Cooled to 35 ° C.

(7) Turbidity.

For the purposes of the present invention, the acceptability of transparency or purity of the composition can be measured qualitatively and quantitatively using a visual method for determining turbidity and a turbidimeter, respectively. Briefly, a visual method involves scanning a visible target through a composition layer with a specific optical path length and determining whether the visible target is distinct or distinguishable. This target may be a straight line, a series of parallel lines, a number or a letter printed on white paper. The test composition was placed in a glass beaker so that the height from the bottom of the beaker to the top surface of the composition was four inches. We made sure that the composition did not contain air bubbles. A piece of paper with a visible target was placed under a glass. We looked through the upper surface of the composition at a visible target. If the visible target seemed similar to the original one, the composition had acceptable transparency and received a valid score. If the visible target to a large extent seemed fuzzy or out of focus compared to the original target, the composition had unacceptable transparency and received an unsuitable rating.

Turbidity can be quantified using a turbidimeter, model IKT-100I, manufactured by δааааn MashGasFtschd 1ps, N.R. Samples rated good according to the visual method should have a haze value of less than or equal to 105 HEM (nephelometric haze units). Samples rated unfit according to the visual method will have a haze value of more than 105 HEM.

The above description and examples illustrate selected embodiments of the present invention. With this in mind, those skilled in the art will be offered variations and modifications, all of which are within the scope of the present invention.
