Description

Cosmetic composition in foam form

This application is a divisional application of an invention patent application with an application date of January 29, 2009, an application number of "200980155877.5", and an invention title of "cosmetic composition in foam form".

technical field

The present invention relates to a composition in the form of a foam for the care and/or makeup of keratin materials.

The composition according to the invention may be, for example, a composition for making up or caring for keratinous substances, especially the skin, lips, eyelashes, eyebrows, or nails. The composition may or may not be coloured.

The cosmetic composition may be selected from, for example, foundations, face powders, eye shadows, cover-up cosmetics, blushers, lipsticks, lip balms, lip glosses, mascaras, eyeliners, and a formula for making up the body or coloring the skin. products. It may especially be a foundation base.

The care composition may be a product, in particular an anti-sun product, for the care of the eyelashes, the lips, or the skin of the body and face.

Background technique

It has been proposed to introduce a gas, usually air, into cosmetic compositions to give them a light texture and the appearance of a foam. This is called overrunning. The emulsions thus obtained in foam form are favored for their lightness on application.

Cosmetic compositions of this type are generally produced in the form of a temporary foam just before use.

These are either aerosol-type products dispensed from a pressurized container (with the aid of a propellant and thus forming a foam) or combinations dispensed from a container using a mechanical pump connected to a dispensing head thing.

However, the currently available compositions in the form of foams are not always completely satisfactory, firstly with regard to the quality of the foam and secondly with regard to the durability of the foam. In most cases, the overall appearance of the foam produced degrades very rapidly upon dispensing. Rather, mousse has a tendency to collapse very quickly.

Improved intumescent compositions have been described in patent application FR0553803, comprising at least one aqueous phase and at least one filler and having a density of less than or equal to 0.12 g/cm ³ .

However, the presence of large amounts of mineral fillers (and more precisely talc) appears to be detrimental to the foam stability over time.

Therefore, there still remains a need for a composition in the form of a foam comprising at least one aqueous phase and talc and exhibiting a satisfactory foam stability over time.

There is also a need for a composition in the form of a foam comprising at least one aqueous phase and at least 1% by weight relative to its total weight of at least one mineral filler and exhibiting a satisfactory follow-up Foam stability over time.

Contents of the invention

The present invention addresses some or all of these needs by addressing a composition in foam form having improved density, especially with regard to stability.

It has now surprisingly been found that it is advantageous to use certain specific UV sunscreen ingredients for these purposes.

It is known from US 2005/0079142 that one or more UV filler substances can be used for foam promotion of self-foaming, foam-like, post-foaming or foamable cosmetic and dermatological preparations comprising at least one extremely oil components.

However, this document does not teach that such UV sun protection ingredients can also be used in compositions in foam form, especially comprising a mineral filler (and especially talc).

Thus, according to one of its aspects, the present invention relates to a cosmetic composition in the form of a foam comprising at least one aqueous phase in a physiologically acceptable medium, talc, and a UV Sunscreen ingredients.

According to another aspect of its aspects, the present invention relates to a cosmetic composition in the form of a foam comprising at least one aqueous phase in a physiologically acceptable medium relative to its total weight At least 1% by weight of at least one mineral filler, and one UV sunscreen ingredient.

The compositions according to the invention in foam form exhibit good stability over time, especially with regard to the homogeneity of the product, the stability of the foam, and the appearance.

The composition in foam form according to the invention can be obtained from a base composition packaged in a product. This product contains a propellant in addition to the base composition.

Therefore, the present invention further relates to a product comprising:

a. A container defining at least one compartment;

b. a composition contained in said compartment, said composition comprising at least one aqueous phase, talc, and a UV sunscreen ingredient in a physiologically acceptable medium;

c. a propellant to pressurize said composition within said compartment; and

b. A composition contained in said compartment comprising at least one aqueous phase in a physiologically acceptable medium, at least 1% by weight relative to its total weight of at least a mineral filler, and a UV sunscreen ingredient;

c. a propellant to pressurize said composition within said compartment; and

d. A dispensing head having an opening to be selectively placed in fluid communication with said compartment for delivering said pressurized composition in a foam form.

According to yet another embodiment, the invention relates to a kit comprising a product as defined above and an applicator.

It also relates to a method for caring for and/or making up the body, in particular the human body, especially the face, comprising a composition in the form of a foam as defined above or a composition as defined above One of the products delivers a composition in the form of a foam to be applied to the surface to be treated and/or made up.

For the purposes of the present invention, the term "composition(s)" refers to a cosmetic composition and/or a base composition.

For the purposes of the present invention, a physiologically acceptable medium is a medium which is compatible with the skin, eyes and/or hair and thus useful for formulating a cosmetic and/or dermatological composition.

The terms "composition in (the) foam form" and the term "composition in a foam form" refer to the same thing and are understood to mean a composition in the form of gas bubbles comprising a gaseous phase (eg air); Another equivalent term is "volume expanded composition".

The composition according to the invention in the form of a foam is advantageous in several respects. In hand it is easy to handle. When applied to the skin, it has a light, fresh feel, creamy and fondant mousse texture. It spreads easily and thinly on the skin and gives the skin an even finish without leaving visible marks. Furthermore, after application to the skin, the obtained make-up or deposit has a powdery, soft finish and is comfortable to use without drying or tightening effects; the made-up or treated skin is pleasantly soft.

Compositions in foam form preferably exhibit a light texture and are easy to remove and spread on keratinous substances.

air or inert gas

Compositions in foam form according to the invention are formed stably in the form of mousses using a base composition and air or an inert gas.

Air or an inert gas may represent especially from 10% to 500% and preferably from 20% to 200%, for example from 30% to 100%, of the volume of the composition in foam form.

The volume can be calculated by comparing the density of the base composition with the density of the composition in foam form.

Gases, in addition to air, which allow obtaining the composition in foam form, in particular inert gases, are, for example, nitrogen, carbon dioxide, nitrogen oxides, noble gases or a mixture of these stated gases. When the composition includes an oxidation-sensitive compound, it is preferred to use an oxygen-free gas, such as nitrogen or carbon dioxide.

The base composition used to obtain the composition in foam form has a composition similar to the composition in foam form, except for its higher density (because it is free of air or inert gas).

The amount of gas introduced into this base composition helps to adjust the density of the composition in foam form to a desired value, for example less than or equal to 0.12 g/cm ³ .

The composition of the present invention in foam form may for example have a density of less than or equal to 0.12 g/cm ³ , for example ranging from 0.02 to 0.11 g/cm ³ and preferably from 0.06 to 0.10 g/cm ³ , this density being according to the following scheme Measured at a temperature of about 20°C and at atmospheric pressure.

Density measurement

The test is performed on a 50ml polish This was carried out with 50 ml of the composition in a goblet (V ₁ ) defining a 30 mm high cylindrical filling space with a 46 mm diameter base. This goblet has a 10 mm thick bottom wall and 12 mm thick side walls.

The composition to be characterized as well as the goblet were kept at a temperature of about 20° C. prior to the measurement. Tare the goblet and record the weight value (M ₁ ). The composition in foam form is then introduced into the goblet so as to occupy the entire volume while avoiding the formation of air bubbles during filling of the goblet. The assembly was left to stand for 10 seconds to allow the mousse to fully expand. The top of the goblet was then skimmed off before weighing ( _M2 ). The density is estimated according to the convention p=(M ₂ −M ₁ )/50.

Stability measurement

The composition according to the invention in the form of a foam shows a satisfactory stability, which can be determined by the stability of the mousse remaining in the goblet after 10 minutes according to the protocol described above for the density measurement. Volume (V ₂ ) was measured to calculate.

The ratio V ₂ /V ₁ corresponds to the ratio between the volume of the composition in foam form after 10 minutes and the volume of the composition in foam form after 10 seconds.

The expression "satisfactory stability" applies especially to having a ratio greater than 0.85 and especially greater than 0.90, for example greater than 0.95 composition in foam form.

For a given weight of the composition in foam form, the volume of the composition in foam form is inversely proportional to the density of the composition in foam form. Thus, the ratio between the density of the composition in foam form measured after 10 seconds and the density of the composition in foam form after 10 minutes may be greater than 0.85 and especially greater than 0.90, eg greater than 0.95.

In the composition according to the invention in foam form, the airpauses may advantageously have a number average size ranging from 20 μm to 500 μm and preferably ranging from 100 μm to 300 μm.

Mention may be made of: mica, kaolin, polyamide powder, poly-β-alanine powder, polyethylene powder, tetrafluoroethylene polymer powder, lauroyl lysine, starch, boron nitride, hollow polymeric microspheres such as those of polyvinylidene chloride/acrylonitrile, e.g. (NobelIndustrie), or: acrylic copolymers, silicone resin powders, especially silsesquioxane powders (especially those described in patent EP293795; e.g. from Toshiba ), polyorganosiloxane particles of elastomers, precipitated calcium carbonate, magnesium carbonate, magnesium bicarbonate, hydroxyapatite, hollow silica microspheres, glass or ceramic microcapsules, and microcapsules derived from 8 to 22 Metal soaps of organic carboxylic acids with carbon atoms and preferably from 12 to 18 carbon atoms, such as zinc stearate, magnesium stearate, lithium stearate, zinc laurate, or magnesium myristate; kind of mixture.

Advantageously, these additional fillers are chosen from low-density fillers. The term "low density" means, for example, fillers having a density of less than 3.5 g/cm ³ and especially less than 3 g/cm ³ . Without wishing to be bound by any theory, it appears that compositions including fillers with too high a density form mousses with higher porosity.

These compositions may comprise low density additional fillers in amounts ranging from 0.5% to 30% by weight, preferably ranging from 1% to 15% by weight and preferably ranging from 1% to 10% by weight.

A low refractive index is, for example, a refractive index of less than 1.7, such as less than 1.6. Extenders that do not substantially absorb water and/or oil in the composition can advantageously help to give the composition a transparent appearance.

These additional fillers having a low refractive index and/or substantially not absorbing water and/or oil in the composition may be present in the composition in an amount ranging from 0.1% to 30%, preferably ranging from 1% to 15% by weight, and preferentially ranging from 1% to 10% by weight.

Among these additional fillers having a refractive index of less than 1.6, substantially not absorbing the water and oil of the composition and having a density of less than 3 g/cm ³ , mention may be made, for example, of fluorophlogopite and its Various mixtures.

Whichever they may be, these additional fillers may be present in the composition in amounts ranging from 0.1% by weight to 35% by weight, preferably ranging from 0.5% by weight to 30%, and preferably range from 1% to 25% by weight.

Advantageously, the fillers under consideration according to the invention may be surface-treated to improve their dispersibility within the composition in foam form. Such treatments form part of the knowledge of the person skilled in the art, and certain fillers so treated are also commercially available.

It goes without saying that the compositions according to the invention may contain additional fillers of high density or refractive index, or absorb water and/or oil in the composition, but in an adjusted amount to obtain a A mousse of satisfactory density and especially low porosity and satisfactory transparency.
