Description

EXAMPLE

Mascaras

[0621] Mascara formulations in accordance with the invention (formulations 1 to 3) or not in accordance with the invention (formulations 4 and 5) are prepared as described below.

[0622] To prepare phase A, the hydrophilic gelling agent is added to water in a heating pan with stirring at 70° C. until a homogeneous mixture is obtained. Stirring is adjusted so as not to incorporate air into the mixture.

[0623] The rest of the ingredients of phase A, the phenoxyethanol, the pentylene glycol and the denatured alcohol are then added at room temperature.

[0624] The components of phase B are weighed out in a heating pan and stirred using a Rayneri blender at 90-95° C.

[0625] Once the gels have been prepared and are homogeneous, the two phases are mixed together using a Rayneri blender at room temperature (25° C.).

[0626] For the formulations according to the invention, a black homogeneous composition forms.

[0627] The formulation is prepared using the weight proportions described below. The percentages are on a weight basis relative to the total weight of the composition.

[0628] Smectite is used in the form of a gel in isododecane (Bentone Gel ISD V® sold by the company Elementis) comprising 10% by weight of smectite and 3% by weight of propylene carbonate.

[0629] The textures of the formulations obtained are evaluated macroscopically and microscopically with a Leica DMLB microscope and a Leica ×10 objective lens.

[0630] Formulations 1 to 3 (in accordance with the invention) form a macroscopically homogeneous mixture in which the observation by microscope reveals that the oily phase and the aqueous phase are both homogeneous.

[0631] Formulations 4 and 5 (comparative), for their part, are in the form of a liquor that is not homogeneous from a macroscopic viewpoint, composed of two immiscible phases, and are consequently not manipulable.

[0632] The viscosity of formulations 1, 2 and 3 was measured using a viscometer (Rheomat RM100 from Lamy Rheology, spindle 4). They have viscosities of 9.9, 4.3 and 1.8 Pa.Math.s, respectively.

[0633] Viscosities of the comparative formulations could not be evaluated since they do not form a macroscopically homogeneous mixture.

[0634] Formulations 1 to 3 obtained are spread on a glass plate to a controlled thickness of 300 μm. After drying for 5 minutes, the tack is evaluated by touching. The formulations according to the invention show a marked decrease in tacky feel, in contrast with the fatty phase alone.
