Abstract

Emulsion comprising an anionic acrylic copolymer and a lipophilic polymer A subject of the present invention is a composition in the form of an emulsion, preferably in the form of an oil-in-water emulsion, comprising at least one hydrophilic gelling polymer chosen from anionic acrylic copolymers and at least one lipophilic polymer comprising at least hydroxyethyl acrylate units and acrylate units bearing a lipophilic group, wherein the weight ratio of the sum of all the hydroxyethyl acrylate units to the sum of all the acrylate units bearing a lipophilic group ranges from 1:30 to 1:1 and wherein the lipophilic polymer has a number-average molecular weight Mn ranging from 2000 to 9000 g/mol. The composition in accordance with the invention makes it possible to obtain emulsions which are homogeneous (the emulsion is macroscopically smooth and has no grains, after storage in a pot for 24 hours at ambient temperature (25° C.)), which have a variable viscosity (very fluid to very thick), which are stable over time, and which have good sensory properties, in particular which are non-tacky, non-shiny and non-greasy on the skin.

Description

EXAMPLES

(1) Example of Lipophilic Polymer Synthesis

(2) Determination of the Molecular Weight by Gel Permeation Chromatography (GPC):

(3) The sample is prepared by preparing a solution of the polymer at 10 mg/ml in tetrahydrofuran. The sample is placed in an oven at 54° C. for 10 minutes and then in an oscillating shaker for 60 minutes in order to assist with the dissolution. After visual inspection, the sample appears to be totally dissolved in the solvent.

(4) The sample prepared was analysed using two polypore 300×7.5 mm columns (manufactured by Agilent Technologies), a Waters 2695 chromatographic system, a tetrahydrofuran mobile phase and detection by refractive index. The sample was filtered through a 0.45 μm nylon filter, before being injected into the liquid chromatograph. The standards used for the calibration are the Easi Vial narrow polystyrene (PS) standards from Agilent Technologies.

(5) Polystyrene standards ranging from 2 520 000 to 162 Daltons were used for the calibration.

(6) The system is equipped with a PSS SECcurity 1260 RI detector. The polystyrene calibration curve was used to determine the average molecular weight. The recording of the diagrams and the determination of the various molecular weights was carried out by the Win GPC Unichrom 81 program.

(7) Determination of the Melting Point by Differential Scanning Calorimetry (or DSC):

(8) This method describes the general procedure for determining the melting point of polymers by differential scanning calorimetry. This method is based on the standards ASTM E791 and ASTM D 34182 and the DSC calibration is carried out according to the standard ASTM E 9672.

(9) Behenyl Acrylate/2-hydroxyethyl Acrylate Copolymer (Polymer 1):

(10) In a 4-necked flask equipped with side-blade mixer, an internal thermometer, two funnels, a reflux condenser, and an extension for two other necks, 175 g of behenyl acrylate, 25 g of 2-hydroxyethyl acrylate and 0.4 g of 2,2′-azobis(2-methylbutyronitrile (Akzo Nobel)) were added, over the course of 60 minutes at 80° C., to 40 g of isopropanol, with stirring, after having removed the oxygen from the system by means of a nitrogen flush for 20 minutes.

(11) The mixture was stirred at 80° C. for 3 hours. The solvent was then eliminated by vacuum distillation, then 1 g of dilauryl peroxide was added and the reaction was continued for 60 minutes at 110° C. The step was repeated. The mixture was then cooled to 90° C. and a jet of demineralized water was added, then the mixture was stirred. The water was eliminated by vacuum distillation.

(12) Molecular weight: Mn=7300 g/mol, Mw=21000, Mw/Mn=2.8

(13) Melting point: 65° C.

Formulation Examples

(14) For each composition, the viscosity was measured and/or the stability over time was studied at various temperatures and/or the sensory aspect was evaluated during and after its application to the skin.

(15) Viscosity Measurement

(16) The viscosity measurement is generally carried out at 25° C., using a Rheomat RM180® viscometer equipped with a No. 3 spindle, the measurement being carried out after 10 minutes of rotation of the spindle in the composition (after which time stabilization of the viscosity and of the speed of rotation of the spindle are observed), at a shear rate of 200 s.sup.−1.

(17) Study of the Stability Over Time at Various Temperatures

(18) The stability is studied over time by observing the change in the composition with regard to its macroscopic appearance, its microscopic appearance, and the change in viscosity and pH values, at various temperatures such as ambient temperature (AT), 4° C. or 45° C.

(19) Protocol for Evaluating the Tack, the Shininess and the Greasiness

(20) The tacky, shiny and greasy effects of the compositions are evaluated by a panel of sensory experts made up of 5 to 20 individuals according to the examples. Each composition is applied to the forearm at the dose of 2 mg/cm.sup.2. The product was spread by circular movements until it had penetrated (approximately 30 seconds). The tacky, shiny and greasy effects are evaluated after 2 minutes of drying, by applying the back of the hand to the treated area, according to a scale ranging from 1 to 15 in which 1 constitutes a reference that is not very tacky or not very shiny or not very greasy, and 15 constitutes a reference that is very tacky or very shiny or very greasy.
