Problems solved by technology

[0010] Another technique consists of gluing false eyelashes on the eyelashes one by one: the effect is not very noticeable and lasts a long time, but the execution is long, expensive and can only be performed by a professional

Embodiment 1 to 8

[0715] Examples 1 to 8: Compositions with a melting point between 40°C and 120°C

Embodiment 1

[0716] Example 1: Assembly comprising a thermoplastic polymer-based composition and a device with a heating element

[0717] 1) Cosmetic composition

[0718] Compositions according to the invention are prepared as described below.

[0719] All starting materials were weighed out using a balance (accuracy 0.01 g). Compounds were melted in a jacketed 500ml heating plate with hot oil circulation for temperature control. Heat the assembly to about 95°C to 98°C.

[0720] Once the mixture is melted, it is homogenized by stirring using a Moritz mixer (rotor-stator type of stirring consisting of a stationary part where a second moving part rotates at a variable speed) in order to disperse the pigment.

[0721] The composition is then deposited on the mold either in liquid form or in solid form at ambient temperature using heat.

[0722] Formulations were prepared using the following weight ratios.

[0723]

[0725] The device used in Example 1 is as ...

Embodiment 2

[0740] Example 2: Assembly comprising a wax-based composition and a device with a heating element

[0741] 1) Cosmetic composition

[0742] Compositions according to the invention are prepared as described below.

[0743] All starting materials were weighed out using a balance (accuracy 0.01 g). Compounds were melted in a jacketed 500ml heating plate with hot oil circulation for temperature control. Heat the assembly to about 95°C to 98°C.

[0744] Once the mixture is melted, it is homogenized by stirring using a Moritz mixer (rotor-stator type of stirring consisting of a stationary part where a second moving part rotates at a variable speed) in order to disperse the pigment.

[0745] The composition is then deposited on the mold either in liquid form or in solid form at ambient temperature using heat.

[0746] Formulations were prepared using the following weight ratios.

Abstract

The present invention relates to a process for cosmetic treatment of one or more keratin fibres, in particular human keratin fibres, especially one or more eyelashes or eyebrows, comprising the moulding of at least one cosmetic composition onto at least one part of said fibre(s), by means of one or more cavities (5) of a mould (2) into which said fibre(s) is (are) at least partially introduced.

Description

technical field [0001] The present invention relates to the cosmetic treatment of keratin fibres, especially human keratin fibres, especially eyelashes or eyebrows. Background technique [0002] Seek to cosmetically treat keratin fibers to give them greater visibility and / or original appearance. [0003] There are known solutions such as applying mascara and using additional fibers. [0004] The first of these two solutions is effective for increasing the visibility of the eyelashes, but is limited in the gain in visibility. [0005] Attempts have been made to exceed this limit, in particular by increasing the amount of deposited material. If the deposited material is increased by suitable brushes or by increasing the number of brushes, the limit is quickly reached due to the fact that the deposited material is almost removed with each new deposition. Frequently produces undesired overload and agglomeration. [0006] This solution is also limited by the number of possibl...
