Problems solved by technology

However, devices such as eyelash curling pliers are rather complicated to use and do not really achieve an even curl of the eyelashes, these devices usually curl the eyelashes in certain places

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, ...
