Cosmetic composition in the form of a compact powder and process for preparing it

The invention relates to a cosmetic composition in the form of a compact powder comprising a fatty phase and a pulverulent phase, said pulverulent phase comprising a first incompactible filler and at least a second filler which may be compactible or incompactible, these two fillers being of different types. The composition preferably has an internal porosity of greater than 2 m.sup.2 /g. The composition is obtained by preparing an oil-in-water type emulsion of the fatty phase in an aqueous phase, dispersing the pulverulent phase in the emulsion, casting the dispersion obtained in a mould, and freeze drying the dispersion.

The present invention relates to a composition, especially a cosmetic 
composition, in the form of a compact powder comprising a fatty phase and 
a pulverulent phase, it being possible for the composition to be used as a 
make-up product. 
The invention also relates to the process for manufacturing the 
composition. 
Some cosmetic compositions, such as foundation, eyeshadow, or blusher, are 
provided in the form of compact powder generally consisting of a fatty 
binder and a pulverulent phase containing pigments and/or fillers. 
Some cosmetic compositions comprise, in addition, a small quantity of 
so-called incompactible filler, especially microspheres of low density, 
because such a filler confers on the composition a very smooth and 
non-greasy feel. Incompactible filler is understood to mean a raw material 
which, above a certain percentage which will depend on the material in 
question, cannot be compacted by means of a mechanical press. 
The compositions of the prior art comprising these small quantities of 
incompactible fillers can have, however, certain drawbacks: the integrity 
of the compacted product obtained is not good during its storage, the 
compacted product does not have sufficient resistance to shock, and/or the 
compacted product does not have a satisfactory flat surface. 
For example, in the prior art compositions, when the compacted product 
comprises hollow microspheres made of thermoplastic material with a 
density of less than 0.1 g/cm.sup.3, the appearance of the onset of 
fragmentation and of breaking-up is observed when the percentage of 
microspheres is greater than about 1% by weight; this degradation is the 
result of relaxation phenomena. 
Various solutions have been proposed in order to overcome the above 
disadvantages. In EP 486 639, it is proposed to mix a pulverulent phase 
and a binder in a nonaqueous solvent, to distribute the fluid paste 
obtained in appropriate moulds and then to evaporate the solvent. The 
particulate phase contains microspheres comprising one or more cavities 
which are open or closed so as to avoid any withdrawal. This process has 
several disadvantages. For example, the solvents are often toxic and thus 
should not be handled. Furthermore, the finished product should not 
contain traces of solvent. On the other hand, the fact that nonaqueous 
solvents are used prevents the use of water-soluble active agents, such 
as, for example. humectants. 
In EP 447 286, a binder and a pulverulent phase containing 0.02-5% of 
hollow microspheres made of thermoplastic material having a density of 
less than 0.1 g/cm.sup.3 and sizes of less than 30 .mu.m are introduced 
into a mechanical press. However, for quantities of microspheres greater 
than 1%, problems of integrity of the compacted product during storage and 
problems of homogeneity of the distribution of the binder in such a filler 
volume appear. Now, it is for proportions greater than 1% that truly novel 
cosmetic qualities are obtained. Furthermore, with microspheres of sizes 
greater than 30 .mu.m, a relaxation phenomenon is observed which causes 
fragmentations in the compacted product. 
In JP-A 62 53914, a process is described which consists of preparing an 
aqueous mixture of cosmetic powders and a water-soluble macromolecular 
compound as binder, casting the mixture in a mould, and freeze-drying it. 
A moulded product of arbitrary shape, but whose cosmetic qualities are not 
sufficient, is thus obtained. 
The aim of the present invention is to overcome the disadvantages of the 
prior art and to propose a composition in the form of a compact powder 
that is stable to storage and has a good cohesion while containing a 
quantity of incompactible fillers which may be high. 
The composition obtained is also solid, that is to say is resistant to 
shock, and has a flat and smooth surface. Even though the composition can 
be referred to as solid, a preferred advantage of the present invention is 
that the composition possesses a porous network, which will be discussed 
in greater detail below. 
The subject of the present invention is a composition in the form of a 
compact powder comprising a fatty phase and a pulverulent phase, said 
pulverulent phase comprising a first incompactible filler and at least a 
second filler, said first and said second fillers being selected from 
inorganic lamellar fillers, organic lamellar fillers, inorganic spherical 
fillers, and organic spherical fillers, said first and second fillers 
being of different types. 
The subject of the present invention is also a process for preparing said 
composition in which the pulverulent phase is dispersed in an oil-in-water 
type emulsion of the fatty phase in an aqueous phase, the dispersion 
obtained is cast in a mould, and said dispersion is freeze-dried. 
One advantage of the invention is to allow the production of a composition 
capable of being provided in diverse and varied, or even complex, forms 
which were difficult to obtain reproducibly according to the prior state 
of the art. 
Indeed, according to a first prior art technique, pulverulent fillers are 
moulded in a press in the presence of a binder, but it is then difficult 
to obtain a constant pressure at all points of the mould if the mould has 
a complicated shape; consequently, the compact powder obtained has fragile 
zones. According to the second prior art technique, a mixture in the form 
of a fluid paste comprising a binder is cast in a mould; when the paste is 
prepared by mixing with water, withdrawal phenomena appear during drying 
and the compact powder obtained is deformed and does not have a flat 
surface. The invention makes it possible to overcome these disadvantages 
and to obtain a composition of diverse shapes. 
Another advantage of the invention is to allow the production of a 
composition having a new texture, of very smooth and non-greasy feel. 
Another advantage of the invention is to allow the production of a 
composition having remarkable cosmetic qualities by virtue of the presence 
of at least two fillers of different types. 
In the remainder of the present description, the percentages are given by 
weight, unless otherwise stated. 
The composition according to the invention is therefore provided in the 
form of a compact powder comprising a fatty phase and a pulverulent phase. 
The pulverulent phase comprises at least a first incompactible filler and 
at least a second filler, which may be compactible or incompactible, each 
filler being chosen from inorganic lamellar fillers, organic lamellar 
fillers, inorganic spherical fillers, and organic spherical fillers, said 
first and said second fillers being of different types. 
Each type of filler makes it possible to offer special and different 
qualities to the composition according to the invention. Thus, for 
example, inorganic lamellar fillers generally offer smoothness, inorganic 
spherical fillers generally offer a good disintegration, and organic 
spherical fillers generally have a structuring role and offer smoothness. 
In order to obtain a composition having good cosmetic properties, it is 
therefore highly preferred to mix at least two fillers of different types. 
Among the lamellar inorganic fillers, there may be mentioned: 
talcs or magnesium silicate hydrates, in the form of particles of sizes 
generally less than 40 .mu.m; 
micas or aluminosilicates of varied compositions and which are preferably 
provided in the form of scales having sizes of 2 to 200 .mu.m, more 
preferably 5-70 .mu.m, and preferably a thickness of 0.1 to 5 .mu.m, more 
preferably of 0.2-3 .mu.m, it being possible for these micas to be of 
natural origin (for example muscovite, margarite, roscoelite, lipidolite, 
biotite) or of synthetic origin. They are generally transparent and make 
it possible to confer a satiny appearance on the skin; 
clays such as sericites, which belong to the same chemical and crystalline 
class as muscovite but whose organoleptic properties are similar to talc; 
kaolin or aluminium silicate hydrate, which is provided in the form of 
particles with isotropic forms having sizes generally less than 30 .mu.m 
and which possess good fatty substance-absorbing properties; 
boron nitrides. 
These fillers are generally compactible. 
However, among these inorganic lamellar type fillers, some are 
incompactible. There may thus be mentioned: 
some talcs, such as "Talc K1" from the company NIPPON or "Talc Extra 
Steamic OOS" from the company LUZENAC; 
some sericites, such as "Sericite BC282" from the company WHITTAKER; 
most mica titaniums when they are used at a high percentage, among which 
there may be mentioned mica-nanotitanium "Coverleaf PC 2055M" from the 
company IKEDA. 
Among the compactible organic lamellar fillers, there may be mentioned 
powders of tetrafluoroethylene polymers, such as "Fluon" from the company 
MONTEFLUOS, or "Hostaflonq" from the company HOECHST. 
Among the incompactible organic lamellar type fillers, there may be 
mentioned the lauroyl lysine "Aminope LL-11" from the company AJINOMOTO. 
Among the compactible inorganic spherical type fillers, there may be 
mentioned: 
zinc and titanium oxides, generally used in the form of particles having 
sizes not exceeding a few micrometres (or even less than 1 .mu.m in the 
case of titanium oxide), in particular spherical titanium dioxides such as 
"SPHERITITAN" from the company IKEDA; these oxides have an unctuous feel, 
a good covering power and a high opacity; 
precipitated calcium carbonate which, in the form of particles of sizes 
greater than 10 .mu.m, has an unctuous feel and makes it possible to 
obtain a matt appearance; 
magnesium carbonate and hydrocarbonate, which has especially perfume-fixing 
properties; 
non-porous spherical silica and 
hydroxyapatite. 
Among the incompactible spherical inorganic type fillers, there may be 
mentioned: 
microspheres of silica with open porosity or, preferably, microspheres of 
hollow silica, such as "SILICA BEADS" from the company MAPRECOS, these 
microspheres being advantageously impregnated with a cosmetic active 
agent, and 
glass or ceramic microcapsules "MACROLITE" from the company 3M. 
Among the compactible spherical organic type fillers, there may be 
mentioned: 
metallic soaps derived from carboxylic organic acids having 8 to 22 carbon 
atoms, preferably 12 to 18 carbon atoms, for example zinc, magnesium or 
lithium stearate, zinc laurate, and magnesium myristate; these soaps, 
generally present in the form of particles having sizes of less than 10 
.mu.m, have an unctuous feel and facilitate the adhesion of the powder to 
the skin; 
powders of non-expanded synthetic polymers, such as polyethylene, 
polyesters (for example polyethylene isophthalate or terephthalate), and 
polyamides (for example Nylon), in the form of particles having sizes of 
less than 50 .mu.m, which possess absorbent properties and make it 
possible to confer a velvety appearance on the skin; 
spheronized powders of synthetic polymers, cross-linked or otherwise, such 
as polyamide powders such as the poly-.beta.-alanine or Nylon powders, for 
example the "Orgasol" powder from the company ATOCHEM, polyacrylic or 
polymethacrylic acid powders, powders of polystyrene cross-linked with 
divinylbenzene, and powders of silicone resin; and 
powders of organic materials of natural origin such as maize, wheat or rice 
starches. 
Among the incompactible spherical organic type fillers, there may be 
mentioned: 
microporous microspheres of polymers, which have a structure similar to 
that of a sponge; they have, in general, a specific surface area of at 
least 0.5 m.sup.2 /g and, in particular, of at least 1 m.sup.2 /g, the 
said specific surface area having no upper limit other than that resulting 
from the practical possibility of producing microspheres of very high 
porosity: the specific surface area may, for example, be as high as 1,000 
m.sup.2 /g or even more. There may be mentioned the microspheres of 
acrylic polymers, such as those in the form of a cross-linked acrylate 
copolymer "Polytrap" from the company DOW CORNING, and those of polymethyl 
methacrylate "MICROPEARL M" or "MICROPEARL M 100" from the company SEPPIC; 
these microporous microspheres may be advantageously impregnated, 
especially with cosmetic active agents: there may be mentioned, in this 
respect, the microspheres of styrene/divinylbenzene copolymers sold under 
the trade name "PLASTIC POWDER FPSQ" by the company TOSHIKI, which are 
impregnated with squalane which is an emollient cosmetic active agent; 
microcapsules of polymers which comprise a single closed cavity and form a 
reservoir, which may contain a liquid, especially a cosmetic active agent; 
they are prepared by known processes such as those described in U.S. Pat. 
No. 3,615,972 and EP-A 0 56219, the disclosures of which are specifically 
incorporated by reference herein. They can be produced, for example, from 
polymers or copolymers of acids, amines or esters, monomers with ethylene 
type unsaturation, urea-formaldehyde polymers, or from polymers or 
copolymers of vinylidene chloride. 
By way of example, there may be mentioned the microcapsules made from 
polymers or copolymers of methyl acrylate or methacrylate, or 
alternatively from copolymers of vinylidene chloride and acrylonitrile; 
among the latter, there should be mentioned especially those which 
contain, by weight, 20-60% of units derived from vinylidene chloride, 
20-60% by weight of units derived from acrylonitrile, and 0-40% by weight 
of other units such as units derived from an acrylic and/or styrene 
monomer. 
There may also be used acrylic polymers or copolymers cross-linked, for 
example in the case of polymers comprising a carboxylic group, with diols 
serving as cross-linking agents. By way of example, there may be mentioned 
the microcapsules made of vinylidene chloride/acrylonitrile copolymer 
"EXPANCEL" from the company Kemanord Plast, the microcapsules "Q-MAX" from 
the company Q-MAX and the microcapsules "3M" from the company 3M. 
The pulverulent phase may comprise 1-100% of incompactible fillers, 
preferably 60-100%, and 0-99% of compactible filler, preferably 0-40%, the 
said percentages being given relative to the pulverulent phase. 
When the incompactible fillers have a very low density, especially of less 
than 0.1 g.cm.sup.-3, they are preferably present in an amount of 2-10% 
relative to the final composition. 
When the incompatible fillers have a density from 0.1 to 0.5 g.cm.sup.-3, 
they are preferably present in an amount of 2-40% in weight relative to 
the weight of the final composition. 
When the incompatible fillers have a higher density, especially greater 
than 0.5 g.cm.sup.-3, they are preferably present in an amount of 30-90% 
in weight relative to the weight of the final composition. 
The pulverulent phase may contain, in addition to the fillers, pigments, 
preferably in a quantity of 0-50% relative to the total weight of the 
final composition. These pigments may be chosen from inorganic pigments, 
organic pigments and pearlescent pigments. 
Among the inorganic pigments, there may be mentioned, for example titanium 
dioxide (rutile or anatase), optionally surface-treated; black, yellow, 
red and brown iron oxides; manganese violet; ultramarine blue; optionally 
hydrated chromium oxide; and ferric blue. 
Among the organic pigments, there may be mentioned for example the pigments 
D & C red, D & C orange, D & C yellow, carbon black, and the lakes based 
on carmine. 
The pearlescent pigments may be chosen especially from the white 
pearlescent pigments such as mica coated with titanium oxide, bismuth 
oxychloride; the coloured pearlescent pigments such as mica titanium with 
iron oxides, mica titanium with ferric blue or chromium oxide, mica 
titanium with an organic pigment of the abovementioned type, as well as 
the pigments based on bismuth oxychloride. 
The composition also comprises a fatty phase. 
This fatty phase may comprise oils and/or waxes of animal, plant, inorganic 
or synthetic origin alone or as mixtures. 
Among the oils which may be used, there may be mentioned vison oil, turtle 
oil, soya bean oil, grapeseed oil, sesame oil, maize oil, rapeseed oil, 
sunflower oil, cottonseed oil, avocado oil, olive oil, pasta oil, jojoba 
oil, groundnut oil; hydrocarbon oils such as paraffin oils, squalane, 
petroleum jelly; fatty esters, such as isopropyl myristate, isopropyl 
palmitate, butyl stearate, hexyl laurate, isononyl isononate, 2-ethylhexyl 
palmitate, 2-hexyldecyl laurate, 2-octyldecyl palmitate, 2-octyldodecyl 
myristate or lactate, 2-diethylhexyl succinate, diisostearyl malate, 
glycerin or diglycerin triisostearate; silicone oils such as 
polymethylsiloxanes, polymethylphenylsiloxanes, polysiloxanes modified by 
fatty acids, fatty alcohols or polyoxyalkylenes, fluorinated silicones, 
perfluorinated oils; higher fatty acids such as myristate acid, palmitic 
acid, stearic acid, behenic acid, oleic acid, linoleic acid, linolenic 
acid or isostearic acid; high fatty alcohols such as cetanol, stearyl 
alcohol or oleyl alcohol. 
Among the waxes which may be used, there may be mentioned beeswaxes, 
lanoline waxes and Chinese waxes; Carnauba, Candelilla and ouricurry 
waxes, cork fibre waxes, sugar cane waxes, Japon waxes, hydrogenated 
jojoba waxes, hydrogenated oils such as hydrogenated sunflower oil, 
hydrogenated castor oil, hydrogenated copra oil and hydrogenated lanolin; 
paraffins, microcrystalline waxes, Montan waxes and ozokerites; 
polyethylene waxes, waxes obtained by Fisher-Tropsch synthesis, waxy 
copolymers as well as their esters, and silicone waxes such as polyalkoxy- 
and polyalkylsiloxanes. 
The fatty phase may, in addition, comprise additives such as lipophilic 
cosmetic active agents and/or fat-soluble ingredients which are generally 
used in cosmetics such as perfumes. Preferably, these additives may be 
present in a quantity of 0-20% relative to the total weight of the fatty 
phase. 
The present invention also relates to a process for preparing a composition 
as defined above, in which the pulverulent phase is dispersed in an 
oil-in-water type emulsion, the dispersion obtained is cast in a mould and 
the dispersion is freeze-dried. 
The dry compact powder obtained may then be optionally removed from the 
mould. 
One advantage of the process according to the invention is that it allows 
the production of compact powders comprising a high level of fillers, 
especially incompactible fillers which powders could not be obtained 
satisfactorily by the prior art processes. 
Another advantage of the process according to the invention is that it 
makes it possible to introduce water-soluble additives into the final 
composition, via the aqueous phase of the emulsion. 
These additives may be, for example, formulation adjuvants or cosmetic 
active agents. 
Among the formulation adjuvants, there may be mentioned thickeners such as 
natural gums, for example, gum arabic, tragacanth gum, and guar gum; 
cellulose derivatives, pectins such as derivatives of alginic acid and of 
carragheen, bentonites and colloidal silicas, polysaccharides, synthetic 
macromolecules especially containing vinyl or acrylic groups, starchy 
materials, phosphor related derivatives of hydroxylated aliphatic alcohol, 
esterified natural or synthetic triglycerides; preservatives such as 
methylparaben; pH modifying agents such as triethanolamine. 
Among the cosmetic active agents, there may be mentioned antioxidants or 
anti-free radical agents; moisturizers or humectants such as glycerin and 
collagen; UV-screening agents such as benzophenone. 
These water-soluble additives may be present in the final composition in a 
quantity of 0-20%, preferably 0.5-10%. 
A specific and preferred embodiment of the process according to the 
invention is described below. 
According to this preferred embodiment, an oil-in-water type emulsion is 
prepared in the presence of a surfactant, such as triethanolamine stearate 
or mixtures of stearic acid and triethanolamine. The quantity of 
surfactant used is preferably 5-15% relative to the total weight of the 
dispersion, and at most 30%. 
The various constituents of the pulverulent phase are then gradually 
introduced into the emulsion obtained so as to obtain a dispersion. The 
dispersion obtained may comprise 0.1-30% of fatty phase, 0.1-65% of 
pulverulent phase and 30-70% of aqueous phase. Preferably, the dispersion 
comprises 1-15% of fatty phase, 1-45% of pulverulent phase and 35-55% of 
aqueous phase. 
Before moulding, the dispersion has, preferably, a viscosity of 0.5-30 
Pa.s, measured at 25.degree. C. with the aid of a rotational viscometer. 
Indeed, when the viscosity is less than 0.5 Pa.s, the composition obtained 
after drying tends to collapse and to be soft. When the viscosity is 
greater than 30 Pa.s, there is some difficulty in filling the moulds. 
The dispersion is introduced into a mould with a wide variety of shapes: 
parallelepipedal, cylindrical, spherical, hemispherical, frustoconical or 
any desired aesthetic shape. 
The mould is then introduced into a freeze-drier. The freezing is 
preferably performed at a very low rate, of the order of 0.5.degree. 
C./min. down to a temperature below the starting melting temperature of 
the dispersion which is generally between -15.degree. C. and -5.degree. 
C., in order to obtain a very fine crystallization of the water. 
When the product is completely frozen, there is primary sublimation of the 
ice crystals; the sublimation pressure is determined by the starting 
melting temperature of the dispersion, the temperature which should 
preferably not be exceeded during the freeze-drying cycle so that there is 
no interstitial melting. Preferably, the sublimation may be performed at a 
pressure of 40 Pa (0.4 mbar) for a starting melting temperature of about 
-12.degree. C. 
The sublimation proceeds until the last ice crystal has sublimed. At this 
very moment, the temperature of the product increases because the 
endothermic phenomenon of sublimation no longer occurs. 
The secondary drying stage is thereby reached: at this stage, the pressure 
is maintained very low, at about 1 Pa and the temperature is brought to 
about 25.degree. C. in order to evacuate the last traces of water. 
The composition is then optionally removed from the mould in the form of a 
dry compact powder which is obtained. 
In general, the composition according to the invention may comprise, after 
freeze-drying, 2-98% of pulverulent phase, preferably 60-97%, and 2-98% of 
fatty phase, preferably 3-40%. 
In a preferred form of the composition according to the invention, the 
composition comprises 45-97% of incompactible filler, 0-40% of compactible 
filler and 3-30% of fatty phase. 
The composition thus obtained may therefore be presented in the form of 
cups, sticks, or cylinders or in any other complex form. 
It has the appearance of a customary compacted powder although it was not 
obtained by compacting with the aid of a mechanical press. 
A feature of the present invention is that the fatty (lipid) phase and/or 
the aqueous thickened phase present in the composition creates a porous 
network; this network remains present in the composition after 
freeze-drying is accomplished. Preferably, the composition of the present 
invention, after freeze-drying, has an internal porosity greater than 2 
m.sup.2 /g, more preferably greater than 3 m.sup.2 /g, and most preferably 
from 4 to 100 m.sup.2 /g.

The present invention is illustrated in greater detail in the following 
examples, which in no way limit the invention.
