no. 1 approach

[0028] According to a first embodiment of the invention, compositions A and B do not contain oxidizing agents and the keratin fibers are not treated with oxidizing agents before or after treatment with compositions A and B. As mentioned above, this oxidative pretreatment opens the scales of the keratin fibers and facilitates the penetration of the dyes.

[0029] According to another embodiment, prior to the application of said compositions A and B, the keratin fibers, in particular the eyelashes and / or the eyebrows, preferably the eyebrows, are pretreated with an oxidizing agent.

[0030] The oxidizing agent may be selected from hydrogen peroxide, carbamide peroxide, alkali metal bromates or ferricyanides, pre-oxidized salts such as persulfates, perborates, peracids and their precursors, and alkali or alkaline earth metal peroxides. carbonate. Preferably, hydrogen peroxide is used.

[0031] In particular, a pretreatment composition C is applied to keratinous fibers, in parti...

Embodiment 1

[0235] Example 1: Eyebrow Dye Preparation in Gel Form

[0236] First composition comprising logan extract

[0237]

[0238] * Logan extract from SCRD company

[0239] Dyeing composition A was prepared according to the following procedure:

[0240] - mix isosorbide dimethyl ether, glycerin, sodium metabisulfite and preservatives with water and stir;

[0241] -Then add carbomer (gelling agent) to the previous phase and mix until completely dissolved;

[0242] - Then add 10% sodium hydroxide to the solution; the preparation thickens immediately;

[0243] -Then add logwood wood extract and mix until completely dissolved;

[0244] - Finally, the resulting gel is homogenized by adding alkyl glucoside surfactants and water;

[0245] - Verify pH is 7 to 7.5.

[0246] Chromogenic composition B comprising ferric gluconate

[0247]

[0248] Chromogenic composition B was prepared according to the following operating procedure:

[0249] - Stir and mix the ingredients exce...

Embodiment 2

[0257] Example 2: Effect of Choice of Penetration Enhancers, Alone or in Combination, on the Longevity of Eyelash Color

[0258] The applicant has demonstrated that the use of one or more penetration enhancers can improve the color performance and longevity of the eyebrows. They tested different reagents, including phospholipids, ceramides, saponins, and fatty acids, and selected the top performers, especially dimethyl isosorbide (Arlasolve DMI from Univar) and PEG-7 glyceryl cocoate (from BASF's HE).

[0259] The results presented below illustrate the role of phospholipids and isosorbide, respectively.

[0260] 2.1 Compared with phospholipids, the effect of isosorbide dimethyl ether

[0261] The different compositions were tested in a panel of 10 individuals.

[0262] Composition A1: Loganwood extract + 2% DMI

[0263] Composition A2: Logan extract + DMI-free cationic dye (small amount)

[0264] Composition A3: Logan extract + lecithin (phospholipid) 1%

[0265] C...

Abstract

The present invention relates to a cosmetic process for dyeing or making up keratin fibres, in particular the eyelashes and / or the eyebrows and preferably the eyebrows, comprising the application, to said keratin fibres, of at least: a) A dyeing cosmetic composition A comprising, in a physiologically acceptable medium, one or more natural dye(s) chosen from the group consisting of neoflavonoids, gallic tannins and catechin tannins, and / or proanthocyanidins and derivatives thereof and mixtures thereof, or one or more plant extracts containing same, and advantageously an antioxidant, b) A revealing cosmetic composition B comprising, in a physiologically acceptable medium, at least one iron salt and / or one aluminium salt, in particular an iron gluconate or an iron sulfate, wherein the composition A is applied before or after the composition B, preferably before the composition B.

Description

technical field [0001] The present invention relates to the field of dyeing or making up keratin fibers, in particular eyelashes and / or eyebrows, preferably eyebrows. Background technique [0002] Compositions for coloring or making up keratinous materials, especially skin or hair, are known in the prior art, which comprise natural dyes, especially plant extracts containing polyphenols. Dyeing methods using natural products, which are more respectful of the nature of the fibers and the environment, are increasingly appreciated by users. [0003] However, the results of dyeing or makeup, especially when applied to keratin fibers, are not always satisfactory in terms of strength and / or uniformity and / or longevity. [0004] Therefore, there is a need to develop new compositions and methods for dyeing or making up keratin fibers, especially eyelashes and / or eyebrows, preferably eyebrows, comprising polyphenol-based natural dyes with improved color properties (intensity and unif...
