Embodiment 1

[0078] Example 1: Lipstick

[0079] -Unclear 80 25.0%

[0080] -Parléam oil 56.0%

[0081] - Polyglyceryl-2-polyhydroxystearate 10.0%

[0082] -Pigment (iron oxide brown + titanium oxide) 9.0%

[0083] preparation:

[0084] Unclear 80 was dissolved in Parléam oil by polyglyceryl-2-polyhydroxystearate at 100°C, and the pigment was added. All the above-mentioned additives are mixed with a deflocculating turbine (Raunerie) and then made into a lipstick in a mold.

[0085] Like this, just obtain a lipstick stick, measure with tissue structure analyzer TA-XT2 at 20 ℃, its hardness is 425 grams. The lipstick obtained above was glossy and did not migrate. Tested by a panel of experts, it was confirmed to be consistent with the gloss of Rouge Absolu de Lancome lipstick made with the current technology. To the comparison test of 2 hours after coating, all test takers think that the gloss of the lipstick of the present invention is higher than the lipstick of the prior art, and the...

Embodiment 2

[0086] Example 2: Anhydrous Eye Cream

[0087] -Unclear 80 25.0%

[0088] -Parléam oil 35.1%

[0089] - Glyceryl Oleate 31.25%

[0090] -Pigment replenished to 100%

[0091] The same method as in Example 1 was used to prepare a glossy non-migrating stick-shaped eye cream.

Embodiment 3

[0092] Example 3: Lipstick

[0093] The difference from Example 1 is that Unclear 100 is used instead of Unclear 80.

Abstract

Structurized composition comprises a colorant and a liquid oil phase structurized by a polymer of mol. wt. 1000-30,000, with a polyamide backbone comprising hydrocarbon repeating units containing a heteroatom(s)and a 12-120C terminal or pendant fatty chain(s) joined to the backbone via the heteroatoms, the chains forming 40-98% of the number of heteroatoms and chains.

Description

technical field [0001] The present invention relates to a care and / or therapeutic and / or cosmetic composition for human skin, including the scalp and / or lips, which contains a liquid lipid phase which can be gelled by special polymers, especially as lipstick Such a cosmetic stick comes in the form of a non-migrating glossy coating when applied. Background technique [0002] In cosmetic or dermatological products, a structured, i.e. gelled and / or hardened, liquid lipid phase is commonly used; this is especially true in solid compositions such as deodorants, balms and lipsticks, anti-dark circle creams and Molded foundation. The structure can be obtained here by means of wax or some fillers. However, these waxes or fillers have a tendency to darken the composition, which is not always desirable, especially in lipsticks; in fact ladies always desire stick lipsticks which form an increasingly glossy coating. [0003] According to the present invention, the term of the liquid ...
