Description

Description Title of the invention: A process for treating keratinous materials using a compound resulting from the condensation of poly(thi)ol and acetoacetate and a crosslinking agent

[0001] — The present invention relates more particularly to the cosmetic field of keratinous materials, and in particular those related to skincare and / or makeup and / or lips and / or eyelashes and / or eyebrows. Its aim is to offer a process implementing on keratinous materials in one or more steps i) at least a compound of formula (I) resulting from the condensation of poly(thi)ol and acetoacetate (ACAC) and ii) at least one crosslinking agent. The invention also relates to compositions comprising ingredients i) and ii) and a kit comprising i) and ii).

[0002] — Cosmetic products conventionally require the implementation of one or several film-forming polymers in order to obtain a quality deposit of these products on keratinous materials, and in particular meeting detailed expectations below.

[0003] — Thus, in the field of skin and lip makeup, it is particularly duly expected that the deposit formed does not transfer upon contact with fingers or the clothes.

[0004] It must also exhibit good resistance to contact with water, particularly rain or during showering, or even from perspiration and sebum, or even at contact with food fats, especially cooking oils, when this A deposit forms on the lips. Furthermore, this deposit must be comfortable, even bright.

[0005] — To achieve this, it is used in makeup products such as mascaras, eyeliners, eyeshadows or lipsticks, and more specifically in their organic phases, particularly oily ones, dispersions of particles of Nanoscale polymer, as a film-forming agent. Thus, document EP 749 '747 proposes using polymer dispersions in hydrocarbon oils acrylics stabilized with dibloc polystyrene copolymers / copoly(ethylene-propylene). Document FR 1 362 795 describes, for its part, the use of dispersion of surface-stabilized polymer particles in hydrocarbon oils. As for document WO 2010 / 046229, it proposes dis- persions in isododecane of acrylic polymers stabilized by sta- polymers bilious.

[0006] … Furthermore, US patent 2006 / 0079599 describes a tissue adhesive based on medical polymers, including polyvinyl alcohol polymers with ACAC groups associated with polyamines in hydrogel form. This document does not describe the use of poly(thi)ol ACAC associated with crosslinking agents and possibly cosmetic active ingredients for application to keratin materials to create a non-sticky, low-transfer, glossy, comfortable, and long-lasting deposit on said materials. There remains a need for cosmetic compositions intended for application to the skin and / or lips and / or eyelashes and / or eyebrows that provide a non-sticky deposit that transfers little or not at all, is shiny, comfortable, and long-lasting. There also remains a need for compositions that are resistant to water and grease, particularly sebum. There also remains a need for compositions that provide qualities of brilliance and transparency. The present invention is specifically designed to meet all or part of these needs. These problems are solved by implementing a process for treating keratinous materials by applying the following to said materials: 1) at least one compound of formula (I) resulting from the condensation of poly(thi)ol and acetoacetate (ACAC) as well as its optical isomers, geometric isomers, salts, and solvates such as hydrates: [Chem. 1]: _ 'oO Le) FOX} rê b 5 Formula (I) in which: R' represents a versatile hydrocarbon radical in C> to C,4, particularly in C3 to C, linear or branched, saturated or unsaturated, conjugated or not, acyclic or cyclic, aromatic or not, R! being further: a) possibly substituted by one or more hydroxy groups OH, amine -N(R)2 with R representing a (C,-C4)alkyl group such as methyl, carboxy -C(O)-OH, a vinyl group, and / or b) possibly interrupted by one or more heteroatoms or groups selected from O, S, carbonyl -C(O)-, amine -N(R'), or their combinations such as ester -C(O)-O-, -OC(O)-, amide -C(O)-N(R')-, -N(R')-C(O)-, urethane -N(R')-C(O)-O- or -OC(O)-N(R')-, urea -N(R')-(CO)-N(R')-, or carbonate -OC(O)-O-, where R° represents a hydrogen atom, an alkyl group having from 1 to 4 carbon atoms possibly substituted by at least one hydroxyl group (OH), or possibly substituted by -XC(O)-C(R,(R,)-C(O)-R? preferably R' represents a hydrogen atom, a (C,-C,)alkyl group; R? represents a monovalent hydrocarbon radical in C, at C, linear or branched, saturated or unsaturated, preferably a (C,-C4)alkyl group such as methyl or tert-butyl, more preferably methyl; Rs and RP, whether identical or different, represent a hydrogen atom or a (C,-C4,)alkyl group, preferably hydrogen; X is a heteroatom or group chosen from O, S, N(R') or , -S-CH, - C(0O)-O-, -OC(O)-CH--S-, -OC(O)-N(R')-, -N(R')-C(0)-O-, N(R')-C(O)-N(R”)-, preferably X represents O; n denotes an integer from 2 to 10, particularly from 3 to 8; and ii) at least one crosslinking agent; and iii) possibly at least one cosmetic active ingredient.

The system remains fluid long enough to allow application to the substrate. After application to a sample of Bioskin synthetic skin and evaporation of the volatile solvents, non-transfer, non-sticky deposits resistant to food oils, sebum, and water are obtained for application to said synthetic skin. Application in 2 steps: apply base coat A then top coat A or apply base coat B then top coat B The base coat composition, containing an acetoacetate compound, is prepared using a Speed ​​Mixer (2 minutes at 3500 rpm). This base coat is applied to a Bioskin-type vitro substrate (an elastomeric skin-simulating substrate) using a film applicator (wet thickness 100 µm). The coating is left to cure for 24 hours. A top coat-type composition containing a crosslinking compound is then applied. After 24 hours of drying, the resulting deposits are evaluated. Base coat A: deposition of a compound | with 6 acetoacetate functional groups alone or diluted in volatile solvents such as ethanol, water, isododecane or a mixture of isododecane / ethanol or ethanol / water. Optionally, a crosslinking agent may be introduced into this phase to perform pre-crosslinking. Or Base Coat B: application of a crosslinking agent 1 to 10. Top coat A: application with a crosslinking agent 1 to 10. Or Top coat B: deposition of a compound | to 6 to functions acetoacetate alone or diluted in volatile solvents such as ethanol, water, isododecane or a mixture of isododecane / Ethanol or Ethanol / water. Base coat compositions comprising compound(s) 1 to 6 with acetoacetate functions (base coat A) or crosslinking agent(s) 1 to 10 (base coat B) were applied to a Bioskin-type in vitro support using a film applicator (wet thickness 100 µm). The deposit was allowed to dry for 24 hours. The new material generated, after evaporation of volatile solvents, produces non-transferable, non-sticky deposits that are resistant to food oils, sebum and water for skin application. Tape resistance A piece of Scotch tape (3M Scotch® Magic!'M 810; 1 = 19 mm x L = 5 cm) is applied to the deposit. A weight of approximately 1070 g is applied to the tape for 30 seconds. The tape is then removed and placed on a microscope slide to observe the result. The film's adhesion to the substrate is thus evaluated. Resistance to olive oil / water / sebum 0.5 mL of olive oil or water is applied to the formulation film. After 5 minutes, the olive oil, water, and sebum are removed by 15 passes with a cotton ball. The film's deterioration following contact with the aggressor droplet is then observed. Bioskin formulation fragmentation test As with the olive oil and tape resistance tests, films are applied to a Bioskin sample. After a day of drying, the Bioskin plate is stretched 10 times by hand. Then the result can be observed on the formulation film (fragmentation or not). For each association, the evaluations were conducted for the base coat alone. after drying and on the [Base coat] + [Top coat] system after drying. The evaluation is done as follows: +++: Cosmetic property rated as very effective ++: Cosmetic property rated as moderately effective +: Cosmetic property rated as having poor performance O0: Cosmetic property evaluated as not performing Resistance to olive oil, sebum and water 0.5 mL of olive oil or water is applied to the deposit. After 5 minutes, the olive oil or water is removed by 15 passes with a cotton ball. The deterioration of the deposit resulting from its contact with the olive oil or water is thus observed. The resistance is evaluated according to the following scale: +++: no damage to the deposit, which is as it was originally; ++: a little bit of transfer but the deposit is as it was originally; +: the deposit is slightly altered and some transfer is observed; 0: the deposit is completely degraded and there is a lot of transfer onto the cotton.
