Cosmetic powder bar composition and process for making same

A cosmetic powder bar composition is disclosed. The composition, substantially oil free, comprises calcium sulfate dihydrate, mica or mica-containing composite material and polyethylene. A unique process for making this composition is also set forth. In this process a powder phase composition and a liquid phase composition are separately prepared. The two compositions are contacted to form a slurry. The slurry is placed in molds and heated to remove free water therefrom.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The solidification of cosmetic powders to produce pressed powder 
compositions is representative of a growing trend in the cosmetic arts. 
This growth in pressed powder compositions can be ascribed to at least two 
advantages that result from such packaging. For one thing, a solidified 
powder is portable. The user is likewise advantaged in that it can be 
applied without the messiness associated with loose powder. Indeed, 
certain cosmetic pressed powders, e.g., eyeshadows, blushes and the like, 
are presently available as solidified powders. That is, finely divided 
loose powders are placed into gaudets, i.e. pans, and under high pressure 
are pressed into cakes. 
Although pressed powders provide the above discussed advantages they 
possess one detrimental characteristic. That is, the powder constituents 
do not bind with each other to form a solid. Thus, a binder, usually in 
liquid form, is added to provide this missing binding property. The use of 
one or more binders, however, is detrimental to users of cosmetic 
compositions who have oily skin. In order to provide beauty enhancement 
users who have oily skin require cosmetics which reduce, rather than 
increase, the oil level of surface layers of the skin. Certainly, the use 
of a cosmetic composition laden with oily binder decreases, rather than 
increases, the product's beauty enhancement to a user having an oily or 
even normal skin. 
Another detrimental property associated with cosmetic powder compositions, 
which are usually pressed powders, is that, by containing high 
concentrations of oily binder, they obviously do not contain water soluble 
but oil insoluble humectants and other like moisturizing agents. The 
inclusion of moisturizing agents in cosmetic products is highly desirable 
in that these agents provide a soft comfortable feel to the skin. 
2. Background of the Prior Art 
A particularly pertinent disclosure of a powder composition is embodied in 
U.S. Pat. No. 4,724,138 to Duffy et al. Duffy et al. describes a method 
for forming a pigmented cosmetic powdered powder product which comprises 
blending a powder phase composition, which includes a powdered pigment and 
calcium sulfate hemihydrate, with an aqueous phase comprising water and a 
surfactant at elevated temperature, i.e., about 60.degree. C. The product 
of this combination is poured into a mold and allowed to set. The product 
is removed from the mold and dried at very high temperature, in excess of 
128.degree. C., to produce a solid employed primarily in cosmetic stick 
products. 
This high heat treatment prevents the cosmetic product from having the 
"feel" deemed attractive to users. That is, the product is not soft due to 
the high curing temperature and the resultant driving off of many 
cosmetically acceptable humectants which evaporate at these high 
processing temperatures. 
U.S. Pat. No. 4,624,273 to Carr, another relevant reference, discloses a 
cosmetic pigmented pencil. The pencil of the Carr patent comprises a core 
consisting of a water-set mixture of plaster of paris, mica or other 
laminar material and pigment or color. The cosmetic composition disposed 
in the pre-formed core may also include preservatives and bacteriostats. 
As in Duffy et al., the Carr patent does not address the need in the art 
for a free standing solid possessing high payoff. Rather than producing a 
free standing powder product, Carr is limited to a cosmetic pencil. 
BRIEF SUMMARY OF THE INVENTION 
A new cosmetic composition has now been developed which not only permits 
the inclusion of humectants and moisturizing agents but which is 
substantially free of oils. In this way, a novel cosmetic powder bar 
composition has been developed which overcomes the problems of high oil 
concentration and the absence of moisturizing agents characteristic of 
cosmetic powder bars of the prior art. 
In accordance with the present invention a cosmetic powder bar composition 
is provided. The composition comprises the calcium sulfate dihydrate, mica 
or mica-containing composite material and polyethylene. 
In further accordance with the present invention a process for making a 
cosmetic powder bar composition is described. In this process a powder 
phase composition, comprising a mixture of calcium sulfate hemihydrate, 
mica or mica-containing composite material and polyethylene, is formed by 
blending these solid components. A liquid phase composition, which 
includes water, is provided. The powder phase and the liquid phase are 
combined to form a slurry. The thus formed slurry is poured into molds at 
ambient conditions. The slurry in molds is then heated at a temperature in 
the range of between about 20.degree. C. and about 70.degree. C. until 
dry. 
DETAILED DESCRIPTION 
The composition of the present invention, a cosmetic powder bar 
composition, comprises a plurality of powdered components, the most 
critical of which is calcium sulfate dihydrate. Those skilled in the art 
are aware that calcium sulfate dihydrate has the structural formula 
CaSO.sub.4.2H.sub.2 O. It is emphasized that calcium sulfate dihydrate is 
distinguished from calcium sulfate hemihydrate which has the structural 
formula (CaSO.sub.4).sub.2.H.sub.2 O. The hemihydrate can be converted 
into the dihydrate by reacting the hemihydrate with water. Specifically, 
three moles of water are reacted with one mole of the hemihydrate to 
produce two moles of the calcium sulfate dihydrate. This conversion 
reaction is discussed hereinafter. 
The calcium sulfate dihydrate constituent uniquely provides bindability to 
the cosmetic powder bar composition. As such, it serves the function 
provided in prior art free standing cosmetic powder bar compositions by 
oil-based binders. Its use thus not only eliminates the requirement that 
the cosmetic powder bar composition include high oil concentration but 
permits the inclusion of water-soluble humectants in the composition. The 
desirable inclusion of humectants is considered in the discussion of that 
component. 
The calcium sulfate dihydrate is preferably present in the cosmetic powder 
bar composition in a concentration in the range of between about 20% and 
about 40% by weight, based on the total weight of the powder bar 
composition. More preferably, the calcium sulfate dihydrate represents 
between about 22% and about 28% by weight, based on the total weight of 
the cosmetic powder bar composition. Still more preferably, the calcium 
sulfate dihydrate component is representative of between about 23% and 
about 25% by weight, based on the total weight of the composition. 
A second critical component of the cosmetic powder bar composition is mica 
or mica-containing composite materials. The mica component contemplated 
for use in the present application is that ingredient recited as mica, 
including those materials recited thereunder as materials containing mica, 
in the CTFA Cosmetic Ingredient Dictionary, Third Edition, published by 
the Cosmetic, Toiletry and Fragrance Association, Inc., Washington, D.C. 
(1982), which text is incorporated herein by reference. 
This essential component is usually present in a concentration in the range 
of between about 16% and about 37% by weight, based on the total weight of 
the composition. Preferably, the concentration of the mica component is in 
the range of between about 19% and about 35% by weight, again based on the 
total weight of the cosmetic powder bar composition. Even more preferably, 
the mica concentration, based on the total weight of the powder bar 
composition, is in the range of between about 22% and about 29% by weight. 
The mica component is crucial to providing high pay-off, an essential 
property of a solid cosmetic powder product. That is, the laminar or 
planar nature of the mica particles allows high levels of pick up when an 
applicator is drawn over the bar. 
Yet a third critical ingredient in the cosmetic powder bar composition is 
polyethylene. 
The polyethylene component of the cosmetic powder bar composition is 
preferably present in a concentration in the range of between about 0.5% 
and about 24% by weight, based on the total weight of the composition. 
More preferably, the cosmetic powder bar composition includes between 
about 5% and about 15% by weight polyethylene, based on the total weight 
of the composition. Still more preferably, between about 7% and about 13% 
by weight of the cosmetic powder bar composition is polyethylene. 
The polyethylene component provides the requisite texture to the solidified 
powder cosmetic product insuring its structural integrity. That is, the 
incorporation of polyethylene eliminates any chance that the composition 
will be friable. As such, the composition is free of powderiness and the 
like. 
In addition to the above essential ingredients of the cosmetic powder bar 
composition, there are several other components that may be included 
therein to insure its effectiveness as a cosmetic product. One such 
preferred component of the cosmetic powder bar composition is talc. The 
talc component of the cosmetic powder bar composition is the material 
denoted by that name in the CTFA Cosmetic Ingredient Dictionary, Third 
Edition, incorporated herein by reference. 
It is preferred that the talc component, if present, be included in a 
concentration in the range of between about 0.1% and about 16% by weight, 
based on the total weight of the composition. More preferably, the talc 
concentration is in the range of between about 4% and about 12% by weight, 
based on the total weight of the cosmetic powder bar composition. Still 
more preferably, the concentration by weight of the talc component in the 
cosmetic powder bar composition is in the range of between about 6% and 
about 10%. 
The talc component is included for its positive "feel" effect. What is 
meant by this is that the inclusion of talc provides a silky feel to the 
skin upon which it is applied. 
Another solid component preferably present in the cosmetic powder bar 
composition is calcium carbonate. The calcium carbonate contemplated for 
use in this composition is the product so denoted in the CTFA Cosmetic 
Ingredient Dictionary, Third Edition, incorporated herein by reference. 
This component is included to absorb moisture on the skin. By doing so, 
this component allows the composition to remain on the user's skin for 
longer periods of time than would otherwise be the case. The absorption of 
moisture prevents the dissolving or dispersion of the composition on the 
skin. 
To provide this function it is preferred that calcium carbonate be included 
in the composition in a concentration range, expressed as a percent by 
weight of the total composition, of between about 1% and about 9.5%. More 
preferably, calcium carbonate is present in the cosmetic powder bar 
composition in a concentration in the range of between about 2% and about 
8% by weight. Even more preferably, the calcium carbonate concentration by 
weight as a fraction of the total weight of the composition is in the 
range of between about 3.5% and about 7%. 
In addition to the above components the cosmetic powder bar composition 
preferably comprises one or more colorants. Cosmetically acceptable 
colorants are utilized to provide color to highlight and accentuate the 
presence of the cosmetic powder bar composition on the skin of the user. 
Preferred colorants are cosmetically acceptable pigments recited in the 
aforementioned CTFA Cosmetic Ingredient Dictionary, Third Edition. Among 
the pigments preferred for use as colorants in the powder bar composition 
are iron oxides, titanium dioxide, carmine, chromium oxide greens, 
chromium hydroxide green, ferric ammonium ferrocyanide, ferric 
ferrocyanide, ultramarine blue, ultramarine violet, ultramarine pink, 
manganese violet, FD&C Yellow No. 5 aluminum lake, FD&C Yellow No. 6 
aluminum lake, FD&C Blue No. 1 aluminum lake, D&C Red No. 7 calcium lake, 
D&C Red No. 30 lake and mixtures thereof, as defined in said incorporated 
by reference CTFA Cosmetic Ingredient Dictionary, Third Edition. Of these, 
iron oxides, titanium dioxide and mixtures thereof are particularly 
preferred. 
The colorant concentration in the composition, expressed in weight 
concentration terms, is preferably in the range of between about 0.1% and 
about 22.5%. More preferably, the concentration of colorant in the 
composition is in the range of between about 2% and about 15% by weight, 
based on the total weight of the composition. Even more preferably, the 
colorant concentration is in the range of between about 4% and about 12% 
by weight, based on the total weight of the cosmetic powder bar 
composition. 
In addition to the above powder phase composition in the formation of the 
cosmetic powder bar composition, the composition of the present invention 
also preferably incorporates components that form the liquid phase 
composition prior to the synthesis of the final cosmetic powder bar 
composition. Of these liquid components the component present in the 
highest concentration, expressed as percent by weight based on the total 
weight of the composition, is a humectant. 
All of the multiplicity of cosmetically acceptable humectants, included in 
the incorporated by reference CTFA Cosmetic Ingredient handbook, First 
Edition, can be employed in the composition of this invention. Of this 
exceedingly large number of cosmetically acceptable humectants, butylene 
glycol, propylene glycol and glycerin, as defined therein, are more 
preferred for use in this composition. Of these, glycerin is most 
preferred. 
The concentration of the humectant, preferably glycerin, is usually in the 
range of between about 1% and about 20% by weight, based on the total 
weight of the cosmetic powder bar composition. More preferably, the 
glycerin concentration, expressed in weight percent based on the total 
weight of the composition, is in the range of between about 4% and about 
14%. Yet more preferably, glycerin represents about 7% to about 12% by 
weight, based on the total weight of the cosmetic powder bar composition. 
Another preferred liquid phase component is an emulsifier. An emulsifier 
permits miscibility between the water and oil soluble components of the 
powder bar composition. The emulsifier is preferably present in a 
concentration in the range of between about 0.75% and about 4% by weight, 
based on the total weight of the composition. More preferably, the 
concentration of the emulsifier is in the range of between about 1.25% and 
about 3.25% by weight, again based on the total weight of the composition. 
Still more preferably, the concentration of the emulsifier is in the range 
of between about 2% and about 3% by weight based on the total weight of 
the composition. 
Although a multiplicity of emulsifiers may be employed in the composition, 
a particularly preferred emulsifier is Polysorbate 20, as defined in the 
CTFA Cosmetic Ingredient Dictionary, Third Edition, incorporated herein by 
reference. 
Yet another ingredient included in the composition of this invention is one 
or more preservatives. The preservative component, usually included in 
cosmetic compositions, may be one or more of the parabens, such as 
methylparaben, ethylparaben, propylparaben and the like, which parabens 
are defined in the aforementioned CTFA Cosmetic Ingredient Dictionary, 
Third Edition, incorporated herein by reference. Other preservatives may 
be alternately or may be additionally included in the cosmetic powder bar 
composition. For example, the composition preferably incorporates 
diazolidinyl urea, as defined in the CTFA Cosmetic Ingredient Dictionary, 
Third Edition, incorporated herein by reference. 
The total preservative concentration, incorporating the one or more 
preservatives included in the composition of this invention, comprises 
approximately 0.5% to approximately 0.75% by weight, based on the total 
weight of the composition. More preferably, the preservative component is 
present in a concentration in the range of between about 0.55% and about 
0.65% by weight, based on the total weight of the composition. 
A final component which is optionally is present in the cosmetic powder bar 
composition is a catalyst. The catalyst component serves to accelerate the 
setting of the cosmetic powder bar as will be explained hereinafter. 
Preferred species of the catalyst of the composition of the present 
invention include potassium sulfate and sodium sulfate. Of these, 
potassium sulfate is particularly preferred. 
The catalyst component is representative of a concentration in the range of 
between 0 and about 0.75% by weight, based on the total weight of the 
cosmetic powder bar composition. More preferably, the catalyst component 
is present in an amount in the range of between about 0.35% and about 0.6% 
by weight, based on the total weight of the composition. 
A second aspect of the present invention involves the unique process by 
which the above-discussed composition is prepared. In the novel process of 
the present invention separate powder phase and liquid phase compositions 
are formulated. 
Turning first to the powder phase composition, that composition 
incorporates calcium sulfate hemihydrate, mica and polyethylene. The first 
mentioned component is preferably present in an amount such that the 
calcium sulfate hemihydrate concentration is in the range of between about 
20% and about 45% by weight, based on the total weight of the powder 
composition. More preferably, the concentration of the calcium sulfate 
hemihydrate is in the range of between about 24% and about 34% by weight 
of the powder composition. Still more preferably, the concentration of the 
calcium sulfate hemihydrate is in the range of between about 26% and about 
30% by weight, based on the total weight of the powder phase composition. 
The mica constituent is preferably representative of between about 15% and 
about 50% by weight of the total weight of the powder phase composition. 
More preferably, the mica constituent is about 25% to about 40% by weight 
of the powder phase composition. Yet more preferably, the mica 
concentration is in the range of between about 28% and about 32% by 
weight, based on the total weight of the powder phase composition. 
The third essential ingredient of the powder phase composition, 
polyethylene, is preferably present therein in a concentration in the 
range of between about 5% and about 30% by weight, based on the total 
weight of the powder phase composition. More preferably, polyethylene 
comprises between about 8% and about 20% by weight of the powder phase 
composition. Still more preferably, the polyethylene constituent is 
representative of between about 10% and about 15% by weight, based on the 
total weight of the powder phase composition. 
The powder phase composition, in a preferred embodiment, includes 
additional components. Among these components is talc. The talc component 
is representative of between about 3% and about 28% by weight, based on 
the total weight of the powder phase composition. More preferably, talc is 
present in an amount in the range of between about 6% and about 18% by 
weight of the powder phase composition. Most preferably, talc comprises 
between about 8% and about 12% by weight of the powder phase composition. 
Another preferred constituent of the powder phase is calcium carbonate. 
Calcium carbonate is preferably included in this phase in an amount in the 
range of between about 2% and about 10% by weight, based on the total 
weight of the powder phase composition. More preferably, the calcium 
carbonate constituency of the powder phase composition, expressed in 
percentage by weight, is in the range of between about 4% and about 8%. 
Yet another preferred constituent of the powder phase composition is one or 
more colorants. The one or more solid colorants preferably included in the 
powder phase composition is representative of between about 5% and about 
30% by weight of the powder phase composition. More preferably, the 
colorant component or components is representative of between about 7% and 
about 20% by weight of the powder phase composition. In an even more 
preferred embodiment, the colorant comprises between about 9% and about 
14% by weight of the powder phase composition. In a particular preferred 
embodiment of the powder phase composition the colorant constituents 
therein are titanium dioxide, iron oxide red, iron oxide yellow and iron 
oxide black. 
In addition to the above components the powder phase composition may 
optionally include a solid phase preservative. As is mentioned below, in 
preferred embodiments of the process of the present invention one or more 
preservatives are oftentimes included in the liquid phase composition. In 
the preferred embodiment where at least one preservative is included in 
the powder phase composition, it is present in an amount in the range of 
between about 0.1 to 1% by weight. If present, it is preferably 
propylparaben. 
As stated above, a liquid phase composition is prepared separately from the 
above-discussed powder phase composition in the process of the present 
invention. The liquid phase composition incorporates, as its major 
constituent, water, in an amount that ranges from between about 60% and 
about 95% by weight, based on the total weight of the water phase 
composition. Preferably, the concentration of water is in the range of 
between about 75% and about 92% by weight of the liquid phase composition. 
Still more preferably, the water constituent is representative of between 
about 80% to about 90% by weight of the liquid phase composition. 
Another preferred component of the liquid phase composition is a humectant, 
preferably, glycerin. The humectant, usually glycerin, component is 
present in a concentration in the range of between about 1% and about 20% 
by weight, based on the total weight of the liquid phase composition. More 
preferably, the humectant constituent is representative of between about 
5% and about 14% by weight of the liquid phase composition. Most 
preferably, the humectant constituent constitutes between about 8% and 
about 11% of the total weight of the liquid phase composition. 
An emulsifier is usually included in the liquid phase composition. When 
present, the emulsifier is preferably provided in a concentration in the 
range of between about 1% and about 5% by weight. More preferably, the 
liquid phase composition comprises between about 2% and about 4% by weight 
of the liquid phase composition. Most preferably, between about 2.5% and 
about 3.5% by weight, based on the total weight of the liquid phase 
composition is the emulsifier. As stated earlier, the preferred emulsifier 
of the liquid phase composition is Polysorbate 20. 
The liquid phase composition also preferably includes one or more 
preservatives. In the preferred embodiment wherein a preservative is 
included in the liquid phase composition, it is preferably present in a 
concentration in the range of between about 0.1% to about 1% by weight, 
based on the total weight of the liquid phase composition. More 
preferably, this concentration is in the range of between about 0.25% and 
about 0.75% by weight. Most preferably, the preservative constituent is 
representative of between about 0.4% and about 0.6% by weight based on the 
total weight of the liquid phase composition. 
It should be appreciated that the preservative constituent of the liquid 
phase composition may be provided by one or more ingredients. In a 
preferred embodiment, two preservatives, methylparaben and ethylparaben, 
are utilized in the liquid phase composition. It is emphasized that the 
presence of at least one preservative constituent in the liquid phase 
composition is independent of the inclusion of a preservative in the 
powder phase composition. 
A last constituent that may be included in the liquid phase composition is 
a catalyst. Preferred catalysts for this application are potassium sulfate 
or sodium sulfate. Potassium sulfate is the more preferred choice as the 
catalyst of the liquid phase composition. Independent of its identity, the 
catalyst, if present, is representative of between about 0.01% and about 
1.00% by weight in the liquid phase composition. 
In the next step in the process of forming the cosmetic powder bar 
composition, the two separately prepared compositions, the powder phase 
composition and the liquid phase composition, are contacted. This contact 
occurs by mixing the two compositions. Preferably, the powder phase 
composition is mixed with the liquid phase composition in a powder phase 
composition to liquid phase composition weight ratio in the range of 
between about 3:5 and 5:3. More preferably, this weight ratio of powder to 
liquid phase compositions is in the range of between about 4:5 and about 
5:4. Most preferably, the amount of powder phase composition to liquid 
phase composition contacted in this step of the process is in the range of 
between about 43:57 and about 45:55. 
The powder phase composition and liquid phase composition are mixed 
together under agitation at room temperature to form a slurry. The slurry 
is poured into molds shaped in accordance with the desired shape of the 
free-standing cosmetic powder bar composition. The slurry is allowed to 
set in the mold for approximately one hour. The set slurry in molds is 
thereupon transferred to a heated environment, usually an oven, maintained 
at a temperature in the range of between about 40.degree. C. and about 
70.degree. C., more preferably, between about 50.degree. C. and 65.degree. 
C. The molds containing the set slurry remain in this heated environment 
for at least 18 hours. The actual time may exceed 18 hours if the cosmetic 
powder bar product in the molds requires more time to reach the minimum 
degree of drying required. It is emphasized that the minimum degree of 
drying required of the final cosmetic powder bar composition is no more 
than 5% by weight free water. 
Although the invention is independent of any theory explaining the 
mechanism of the above described process, it is theorized that water 
included in the liquid phase composition reacts with the calcium sulfate 
hemihydrate constituent of the powder phase composition to form calcium 
sulfate dihydrate. Thus, although there are water molecules in the 
cosmetic powder bar composition, none of these are free water molecules. 
These water molecules are tied up as part of the dihydrate molecule. 
It is noted that the presence of a catalyst accelerates the reaction of 
calcium sulfate hemihydrate to calcium sulfate dihydrate at ambient 
conditions. It is furthermore emphasized that any more than 5% by weight 
excess free water, i.e., water present in excess of that 
stoichiometrically required in this reaction, is driven off in the heating 
step. 
The following examples are given to illustrate the scope of the present 
invention. Because these examples are given for illustrative purposes 
only, the invention should not be limited thereto.

EXAMPLE 1 
Preparation of a Powder Phase Composition 
A mixing container provided with agitation was charged with the following 
solid components, wherein parts denotes parts by weight: 6.4 parts calcium 
carbonate, 9.6 parts titanium dioxide, 0.72 part iron oxide red, 1.0 part 
iron oxide yellow, 0.12 part iron oxide black and 0.06 part propylparaben. 
These solid components were mixed, pulverized and passed through an 0.02 
inch screen. The resultant product was a color powder mixture. 
A second solid mixture was prepared in a blender by adding 31.3 parts mica, 
12.7 parts polyethylene, 27.6 parts calcium sulfate hemihydrate and 10.5 
parts talc therein. It should be appreciated that parts again mean parts 
by weight. The solid components were blended until a uniform solid mixture 
was obtained. 
Upon obtaining a uniform mixture, the solid color powder mixture in the 
mixing container was added to this second solid mixture in the blender and 
the two solid mixtures were blended together until a uniform powder phase 
composition was obtained. 
EXAMPLE 2 
Preparation of a Liquid Phase Composition 
A tank provided with a propeller type agitation was charged with 9.46 parts 
glycerin, 0.24 part methylparaben and 0.10 part ethylparaben. Again, all 
parts recited are parts by weight. These ingredients were mixed until the 
methylparaben and the ethylparaben were completely dissolved in the 
glycerin. 
In a larger tank, also provided with propeller type agitation, 86.77 parts 
of water were introduced. The charging into the tank of the water 
corresponded to the introduction of agitation therein. After all the water 
had been charged into the main tank, 0.54 part potassium sulfate, 2.70 
parts Polysorbate 20 and 0.19 part diazolidinyl urea were added thereto. 
Mixing continued until all the solids were dissolved in the water. At this 
point the solution of glycerin, methylparaben and ethylparaben was added 
to the contents of the larger tank. The two liquid solutions were then 
mixed together to provide a uniform liquid phase composition. 
EXAMPLE 3 
Preparation of a Cosmetic Color Bar Composition 
44.5 Parts by weight of the powder phase composition, formed in accordance 
with Example 1, were combined with 55.5 parts by weight of the liquid 
phase composition, produced in Example 2, at ambient conditions. The two 
compositions were mixed until a uniform slurry was obtained. Upon 
obtaining a uniform slurry, the slurry was poured into molds and allowed 
to set for one hour at ambient conditions. Thereupon, the molds were 
transferred into an oven maintained at a temperature in the range of 
between about 50.degree. C. and about 55.degree. C. The slurry, maintained 
in the molds, was held in the oven for about 18 hours. Upon removal from 
the oven a dry cosmetic powder bar composition was formed in each of the 
molds. 
The above embodiments and examples are given to illustrate the scope and 
spirit of the present invention. These embodiments and examples will make 
apparent, to those skilled in the art, other embodiments and examples. 
These other embodiments and examples are within the contemplation of the 
present invention. Therefore, the present invention should be limited only 
by the appended claims.
