ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a novel cosmetic two-coat makeup process for the skin and/or the lips and/or integuments by applying successively to human skin either of the face or the body, to the lower and upper eyelids of human beings, to the lips and to integuments such as the nails, the eyebrows, the eyelashes or the hair, at least one first and one second composition. The invention also relates to a make-up kit containing the first and second compositions.
Each of the compositions may be a free or compacted powder, a foundation, a face powder, an eyeshadow, a concealer product, a blusher, a lipstick, a lip balm, a lip gloss, a lip pencil, an eye pencil, a mascara, an eyeliner, a nail varnish or a body makeup or skin-coloring product.
2. Description of the Background
Make-up compositions for the skin or the lips of human beings, such as foundations or lipsticks, generally contain fatty phases such as waxes and oils, pigments and/or fillers and optionally additives, for instance cosmetic or dermatological active agents. They may also contain “pasty” compounds of soft consistency for obtaining colored or uncolored pastes, to be applied with a brush.
The known compounds have a tendency to migrate, that is to say to travel over time in the folds of the wrinkles and fine lines of the skin which especially surround the lips and the eyes, resulting in an unattractive effect. This migration is often mentioned by women as a major defect of standard lipsticks and eyeshadows. The term “migration” means a running of the composition and in particular of the color beyond the initial line of the make-up. In addition, these compositions have poor staying power over time, in particular of the color. This poor staying power is characterized by a modification of the color (color change or fading) generally following an interaction with the sebum and sweat secreted by the skin in the case of foundations and face powders, or of an interaction with saliva in the case of lipsticks. This obliges the user to apply fresh make-up very regularly, which may constitute wasted time.
For several years, cosmetic research has focused on “transfer-resistant” make-up compositions for the lips and the skin, that is to say compositions which have the advantage of forming a deposit that does not become deposited, at least partly, on the surfaces of supports with which they come into contact (glass, clothing, cigarettes, fabrics, etc.).
The known transfer-resistant compositions are generally based on silicone resins and volatile silicone oils and although having improved properties as regards staying power, have the drawback of leaving on the skin and the lips, after the volatile silicone oils have evaporated off, a film that becomes uncomfortable over time (sensation of dryness and of tautness), which puts a certain number of women off this type of lipstick.
In addition, these compositions based on volatile silicone oils and silicone resins produce matte colored films. However, women are nowadays looking for products, especially for coloring the lips or the eyelids, that are glossy while at the same time having good staying power and being transfer-resistant.
In order to overcome these drawbacks, Applicant has envisaged the manufacture of make-up compositions containing dispersed polymer particles surface-stabilized with a stabilizer in a liquid fatty phase, as described in EP-A-0 930 060. However, these compositions do not make it possible to achieve a really glossy make-up effect, which is always desired by consumers.
Moreover, Japanese patent application JP-A-05 221 829 assigned to the company Kose proposes the use of a gel based on perfluoro materials, which is applied over a film of lipstick so as to prevent it from transferring onto other surfaces, the gel being incompatible with the film of lipstick.
Although the use of perfluoro oils ensures incompatibility between the gel and the film of lipstick and thus staying power and transfer-resistance properties, formulations of this type have the drawback of possessing poor cosmetic properties, because the film of lipstick becomes oily and is liable to migrate, which is unacceptable for consumers.
Moreover, patent application WO-A-97/17057 assigned to the company Procter & Gamble, describes a method for increasing staying power and transfer-resistance properties, by applying two compositions, one over the other. These two compositions satisfy the following physicochemical criteria:
global Hildebrand solubility parameters of less than 8.5 (cal/cm
3
)
1/2
for the composition applied first,
presence of oil whose calculated partition coefficient ClogP is at least equal to 13 for the topcoat.
However, the selection of this composition does not exclude the possibility of having the same constituents in the two compositions. Specifically, triglycerides, in particular sweet almond oil and olive oil, mentioned as satisfying the partition coefficient criteria, also have Hildebrand solubility parameters of less than 8.5 (cal/cm
3
)
1/2
(Vaughan C. D. “Solubility effects in product, package, penetration and preservation”, Cosmetics and Toiletries, vol. 103, pp. 47-69, 1988):
Sweet almond oil: 6.81 (cal/cm
3
)
1/2
.
Olive oil 7.87 (cal/cm
3
)
1/2
.
Consequently, there is a certain level of compatibility between the two coats, which does not make it possible to achieve entirely satisfactory staying power and transfer-resistance properties.
Finally, U.S. Pat. No. 6,001,374 from Nichols proposes a multilayer make-up system that consists in using a composition containing an alcohol-soluble and water-insoluble resin, which may be applied as a basecoat or as a topcoat, and which has the advantage of not leaving marks on the surface of a support placed in contact with the make-up, and of being resistant to water and to friction, while at the same time possessing a certain level of gloss. However, this composition contains a water-soluble alcohol, in particular ethanol, which is a compound that has an irritant, dehydrating nature on the skin and more particularly on the lips, and which is particularly uncomfortable when the skin or the lips are damaged. Furthermore, this composition requires the use of a particular make-up remover, which is not particularly practical.
SUMMARY OF THE INVENTION
Accordingly, one object of the present invention is to provide a process for preparing a make-up which, simultaneously, is transfer-resistant, does not migrate, has good staying power, is comfortable, does not have a dehydrating effect, is not greasy, and is glossy, this result not having been satisfactorily obtained in the past.
Briefly, this object and other objects of the present invention as hereinafter will become more readily apparent can be attained by a cosmetic make-up process for the skin and/or the lips and/or integuments of a human being, which comprises:
applying to the skin, the lips and/or integuments a first coat of a first composition comprising, in a first physiologically acceptable medium, dispersed polymer particles surface-stabilized with a stabilizer in a liquid phase;
permitting the first coat to dry; and then
applying over all or a part of the first coat, a second coat of a second composition comprising, in a second physiologically acceptable medium, a silicone-based and/or fluoro-based liquid phase.
BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENTS
It has now been found, surprisingly, that by applying to the skin, the lips and/or integuments a first composition comprising a first physiologically acceptable medium containing dispersed polymer particles surface-stabilized with a stabilizer in a liquid phase and then a second composition comprising, in a second physiologically acceptable medium, a silicone-based and/or fluoro-based liquid phase, a glossy two-coat make-up is obtained, which does not migrate and does not transfer, while at the same time being comfortable when applied and over time (does not dehydrate the skin or make it taut).
In particular, the process of the invention permits the deposition of cont
