example 1

[0178] Heat-shrinkable fibers were produced in the following manner. PETG 5116 filaments (commercially available from Eastman Chemical Products, Kingsport, Tenn) were extruded to have a diameter of 20 microns. The filaments thus obtained are then drawn to a ratio of 1 / 1.5 in a water bath heated to 70° C. according to standard methods known to those skilled in the art. These fibers are then cut again so that the length does not exceed 3 mm.

[0179] The fibers thus obtained were used to prepare the following compositions:

[0180]

[0181] Apply the obtained composition to the eyelashes using a mascara brush. After drying, a 70°C heating probe in the shape of a cylinder with a diameter of 3 mm was applied to the dried deposit in order to activate the shrinkage of the fibers. Increased curling of the eyelashes was subsequently observed.

example 2

[0183] Heat-shrinkable fibers were prepared according to the protocol described in Example 3 of patent application US 5439438 (before manufacturing non-textiles by embossing process). The fiber is then cut again so that the length does not exceed 3 mm.

[0184] The fibers thus obtained were used to prepare the following compositions:

[0185]

[0186] Apply the obtained composition to the eyelashes using a mascara brush. After drying, a 70°C heating probe in the shape of a cylinder with a diameter of 3 mm was applied to the dried deposit in order to activate the shrinkage of the fibers. Increased curling of the eyelashes was subsequently observed.

Abstract

Composition for making up and/or caring for keratin fibres, comprising fibres that are capable of changing in length and/or shape in response to an external stimulus.

Description

technical field [0001] The present invention relates to the field of make-up and care of keratin fibers, especially eyelashes, and more particularly to mascara compositions. Background technique [0002] Eyelash coating compositions such as mascaras are generally cosmetic compositions, cosmetic eyelash care compositions or compositions to be applied while making up, also known as top coats. [0003] Mascara generally falls into two categories: water-based mascara, also known as "mascara," which includes a dispersion of wax in water; and anhydrous mascara, which has a low water content, also known as "Waterproof mascara", which includes a dispersion of wax in one or more organic solvents. [0004] The present invention relates more particularly to water-based mascaras. In addition to the care and / or cosmetic benefits provided by mascaras, their users also desire the ability of mascaras to curl the eyelashes. [0005] Thus, while standard mascaras can often curl eyelashes, ...
