Problems solved by technology

In this case, however, the makeup on the lashes was light and didn't quite do the trick
[0016] Performing eyelash extensions is also unsatisfactory as it requires considerable work and is often costly

example 1

[0843] Example 1: Assembly comprising a thermoplastic polymer-based composition and a device with heating elements

[0844] 1) Cosmetic composition

[0845] The composition according to the invention is prepared as described below.

[0846] Use a balance to weigh out all the starting materials used (accuracy 0.01g). The compound was melted in a jacketed 500ml heating plate with hot oil circulating to control the temperature. The assembly is heated to about 95°C-98°C.

[0847] Once the mixture is melted, it is homogenized by stirring using a Moritz stirrer (a rotor-stator type stirring composed of a fixed part in which a movable second part rotates at a variable speed) to disperse the pigment.

[0848] The composition is then used in a liquid form under heating to deposit on a mold or in a solid form at room temperature to deposit on a mold.

[0849] The formulation was prepared using the following weight ratio.

Abstract

The present invention relates to an assembly comprising: at least one cosmetic composition for the cosmetic treatment of eyelashes or eyebrows, and a device comprising a mould comprising two mould parts (2a, 2b) to be closed on the eyelashes, at least one of these parts having a concave groove (160), which is concave towards the proximal edge (150) of the mould, especially curvilinear, allowing the formation of a strip of composition connecting at least part of the eyelashes along the eyelid or the eyebrow arch.

Description

Technical field [0001] The present invention relates to the cosmetic treatment of human keratin fibers, especially eyelashes or eyebrows. Background technique [0002] Attempts have been made to treat keratin fibers cosmetically to give them greater visibility and / or original appearance. [0003] There are known solutions such as applying mascara and using extra fibers. [0004] The first of these two solutions is effective for increasing the visibility of eyelashes, but has limitations in increasing visibility. [0005] Attempts have been made to surpass this limitation, especially by increasing the amount of deposited material. If the deposited material is increased by a suitable brush or by increasing the number of brushes, since almost as much material is removed in each new deposit as is deposited, the limit will soon be reached. Unwanted overload and condensation are often generated. [0006] This solution is also limited by the number of possible aesthetic effects. For exampl...
