Problems solved by technology

[0013] However, especially in the case of facial cleansing aimed at cleansing the pores of the skin or removing impurities, excess sebum, dead cells or traces of make-up from the skin, it is preferred that the cleansing formulation produces a foam of low volume and that the bubbles making up the foam are stable. and of sufficiently fine average size during the cleaning phase to limit the risk of contact with the eye and thus eye irritation resulting in uncomfortable eye stinging for the consumer

Embodiment 1

[0165] 1.1. Preparation of ammonium 2-methyl 2-[(1-oxo2-propenyl)amino]1-propanesulfonate, N,N-dimethyl Terpolymer of acrylamide and tetraethoxylated lauryl methacrylate [AMPS / DMAM / MAL (40E) 77.4 / 19.2 / 3.4 moles] [Example of the present invention]

[0166] 592 g of a 15% by mass aqueous solution of 2-methyl 2-[(1-oxo2-propenyl)amino]1-propanesulfonate ammonium in a tert-butanol / water mixture (97.5 / 2.5 volume), 10.1 g of N,N-dimethylacrylamide, 4.2 g of tetraethoxylated lauryl methacrylate and 0.75 g of trimethylolpropane triacrylate were charged into a reactor maintained at 25°C under stirring.

[0167] After a time sufficient to achieve good homogenization of the solution, the solution was deoxygenated by bubbling nitrogen gas heated to 70°C. Then 0.42 g of dilauroyl peroxide are added and the reaction medium is then kept at 70° C. for about 60 minutes and then at 80° C. for 2 hours.

[0168] After cooling, the powder formed during the polymerization was filtered and dried t...

[0182] A—Preparation of cleaning compositions comprising polyelectrolyte 1, and comparative formulations

[0183] Pour water into the beaker at 20°C in the mass ratios listed in Table 1, then gradually pour the foaming surfactant with mechanical stirring at 50 rpm, then gradually pour the thickener, then the neutralizer (acidic or basic, depending on the formulation) to obtain the desired pH. Inventive formulations (F1), (F11), (F12) and (F13) and comparative formulations (F2)-(F10) were obtained.

Abstract

The invention relates to a method for improving the foaming properties of cleaning compositions for topical use, having a pH of no lower than 4.0 and no higher than 6.5, and including at least one foaming surfactant, said method being characterized in that an effective quantity of a cross-linked anionic polyelectrolyte (P) is incorporated into said cleaning composition for topical use, said cross-linked anionic polyelectrolyte being obtained through the polymerization, in the presence of at least one cross-linking agent, of at least one monomer having a strong acid function, said monomer being 2-methyl 2-[(1-oxo 2-propenyl) amino] 1-propanesulfonic acid, which is partially or completely salified, with at least one neutral monomer selected from the N,N-dialkyl acrylamides,; wherein each of the alkyl groups comprises between one and four carbon atoms and at least one monomer of formula (I), in which R is a linear or branched alkyl radical comprising eight to twenty carbon atoms, and n is a number greater than or equal to one and less than or equal to twenty. The invention also relates to novel compositions which contain the polyelectrolyte (P), foaming surfactants, and acid agents selected from among the a-hydroxy acids and beta-hydroxy acids, as well as to the use thereof in cosmetics.

Description

[0001] This application is a divisional application of the invention patent application with the application number 201280042288.8. The filing date of the original application is August 24, 2012. The title of the invention is "a new method for improving the foaming performance of a topical cleansing composition". technical field [0002] The invention relates to the field of cosmetic and / or pharmaceutical industry. The subject of the present invention is a new method for improving the foaming properties of cleansing and / or foaming formulations, as well as new compositions and processes for their preparation. Background of the invention [0003] Cleansing formulations for the face, body and hair, and more generally body and hair hygiene products in the form of shampoos, lotions, gels or liquid soaps, require the formation of a foam during their application to the body part to be cleansed . This is because the formation of foam constitutes one of the evidences of cleaning eff...
