[0187] Preparation of the composition
[0188] The compositions according to the invention are prepared according to a procedure comprising the following steps.
[0189] The acrylic copolymer is dispersed in water.
[0190] The aqueous dispersion of acrylic copolymer is heated at a temperature of 60-70°C, preferably 65°C.
[0191] Additives, if present, are added to the aqueous composition of the acrylic copolymer.
[0192] Add the foaming surfactant at a temperature of 60-65°C.
[0193] Neutralizing agent (if present) is added at a temperature of 55-65°C.
[0194] The hydrogel beads are added to the composition with stirring.
[0195] Application of the composition
[0196] The present invention also relates to the use of a composition as previously described comprising beads, at least one foaming surfactant and an acrylic copolymer in an aqueous medium as a scrub composition for the skin, preferably for the face or body , wherein the beads comprise at least two gel...
Embodiment 1-4
[0211] Example 1-4 : Influence of polymer properties
[0212] Two compositions according to the invention (Examples 1 and 2) comprising polymers from the class of crosslinked acrylic copolymers (Carbopol ETD 2020 and Carbopol Ultrez 20) were prepared and combined with Two comparative compositions (Examples 3 and 4) comprising cellulosic polymers (hydroxypropylmethylcellulose and hydroxyethylcellulose) were compared, as shown in the following table:
[0213]
[0214] The texture and visual appearance (visual observation) of each composition was studied after two months of storage at 25°C. The composition was considered stable if no change in visual appearance was observed after two months storage at 25°C and if the beads remained suspended. The results are summarized in the table below:
[0215] formula
Observed
Example 1
Gel texture (2.6Pa.s), translucent, beads remain suspended after two months at 25°C
Example 2
Gel texture (3.8Pa.s),...
Embodiment 5-7
[0219] Example 5-7 : Influence of Surfactant Properties
[0220] Three compositions (Examples 5 to 7) were prepared according to the invention and containing various surfactants (sodium laureth sulfate, cocamidopropyl betaine, decyl glucoside) as detailed in the table below. ).
[0221]
[0222] Each composition was evaluated for texture, appearance and stability. The texture and appearance of the compositions were evaluated by visual observation at 25°C. Stability was evaluated after one month of storage at various temperatures (4°C, 37°C and 45°C). The composition was considered stable if no change in visual appearance was observed after storage at these temperatures for one month and if the beads remained suspended. The results are summarized in the table below:
[0223] formula
Observed
Example 5
Gel texture (3.6Pa.s), translucent, stable
Example 6
Gel texture (4Pa.s), translucent, stable
Example 7
Gel texture (3.2Pas...
