Preparation Protocol

[0190] First of all, the aqueous internal phase gelled with Simulgel EG was prepared at a temperature of 55 C. (B1+B32) with a Rayneri mixer.

[0191] The emulsion was then formed by adding the aqueous phase A heated to 80 or 85 C. Phase C was added at 1000 rpm.

[0192] The fillers and the nacres were then added to the preparation at 50 C.

[0193] At ambient temperature (25 C.), phases E and F were added at 120 rpm.

[0194] This composition 1 of the invention was compared, in terms of correction of the relief, of satin effect and of radiant effect, to a reference composition 2 on the care products market: Corrector Hydrating Cream Perfect SkinSublimistL'OREAL PARIS having as list of ingredients:

[0195] AQUA (WATER), DIMETHICONE, GLYCERIN, ISOPROPYL ISOSTEARATE, PENTAERYTHRITYL TETRAETHYLHEXANOATE, OCTYLDODECANOL, CETYL ALCOHOL, SILICA (NANO)/SILICA, BEHENYL ALCOHOL, TALC, PTFE, POLYETHYLENE, EPERUA FALCATA BARK EXTRACT, PEG-100 STEARATE, STEARIC ACID, STEARYL ALCOHOL, CARBOMER, ARACHIDYL ALCOHOL, DIMETHICONE/VINYL DIMETHICONE CROSSPOLYMER, CETEARYL ALCOHOL, CETEARYL GLUCOSIDE, SODIUM HYALURONATE, SODIUM HYDROXIDE, PALMITIC ACID, ADENOSINE, POLOXAMER 338, AMMONIUM POLYACRYLDIMETHYLTAURAMIDE/AMMONIUM POLYACRYLOYLDIMETHYL TAURATE, DISODIUM EDTA, CAPRYLOYL SALICYLIC ACID, CAPRYLYL GLYCOL, LENS ESCULENTA (LENTIL) SEED EXTRACT, DEXTRIN, PHENOXYETHANOL, CI 16035 (RED 40), CI 17200 (RED 3), LINALOOL, ALPHA-ISOMETHYL IONONE, LIMONENE, CITRAL, CITRONELLOL, FRAGRANCE, F.I.L B159063/2.

Sensory Tests (In Vivo)

[0196] A qualitative in vivo test was carried out on a panel of 12 women, all regular users of day cream with a glowing effect; normal to dry skin, with very light to medium complexions, with slight imperfections (except redness).

[0197] The 12 women are divided up into two age groups: half are between 30 and 36 years old and the other half are between 37 and 45 years old. They are also divided up equally according to their skin type: 4 women having normal skin, 4 having mixed skin and 4 having dry skin. They exhibit:

[0198] All the women exhibit fine lines (more or less accentuated depending on age and skin nature of the women). None exhibits localized redness, in particular on the cheeks and/or the top of the forehead.

[0199] The test was carried out at home on each of the two formulations 1 and 2 for 3 days.

Results

[0200] All of the evaluating women found that formula 1 according to the invention produced an even and uniform complexion, and a visual smoothing out effect reducing the appearance of fine lines while at the same time depositing a satiny lightness on the entire face.

[0201] All of the evaluating women found that reference formula 2 on the face care market for relief correction produced an even and uniform complexion, and a visual smoothing out effect reducing the appearance of fine lines, but, contrary to example 1 of the invention, gave a powdered matt rendering at the surface and a lack of luminosity.

Soft-Focus Corrective Effect Tests (In Vitro)

[0202] The soft-focus corrective effect of each of Examples 1 and 2 was measured. Said soft-focus effect is characterized by haze and transparency (transmittance TH) measurements. Haze corresponds to the percentage of light scattered relative to the total transmittance according to standard ASTM D 1003 (Standard Test Method for Haze and Luminous Transmittance of Transparent Plastics).

[0203] 25 m films of composition were applied to 50 m polyethylene (PE) films. The film was then measured after 1 hour of drying at ambient temperature (25 C.). Finally, the film was placed in the machine and transparency and haze measurements were carried out.

Results

[0204] The results are summarized in the following table:

TABLE-US-00002 Transparency Composition tested (Transmittance TH) Haze Example 1 (invention) 92.5% 92.13% Reference Example 2 91.8% 61.4%

[0205] It results from this that the composition of Example 1 according to the invention showed good imperfection correction performance levels, an even and uniform complexion and a radiant satin effect, contrary to Reference Example 2. Furthermore, Example 1 showed a better soft-focus corrective effect, which results in a haze that is substantially higher compared with Reference Example 2.
