BACKGRQUN~

This invention relates to cosmetic cover compositions 15 which are mineral oil free and lanolin free --i.e., contain no mineral oil and no lanolin (wool fat).
U.S. 4,659,573 issued to Frischling et al. on April 21, 1987 discloses an ester blend comprising tridecyl trimellitate blended with at least one additional ester selected from the group consisting of 20 dipentasrythritol hexacaprylata/hexacaprate, tridecyl stearate and neopentyl glycol dicaprylate/dicaprate. It is disclosed that the blend contains about 5 to about 85 wt% tridecyl trimellitate based on the weight of the blend. It is aiso disclosed that these ester blends are a substitute for mineral oil in toiletry and cosmetics. According to U.S.
25 4,65g,573 the disclosed ester blends are suitable for use in night creams, moisturizers, lotions, make-ups, face creams, day creams, body lotions, lipsticks and lip glosses.
The technical information brochure for SOFTISAN~649 (Huls Troisdorf AG) discloses that this product is the glycerin ester of 30 natural vegetable fatty acids, of an jsoctearic acid, and of the adipic acid, and that this product has the CTFA adopted name: caprylic/capric/
isostearic/adipic triglyceride. It is disclosed that when SOFTISAN 649 is stirred in warm water it will form an emulsion having the properties of woolwax. It is also disclosed that emulsions containing SOFTISAN 649 35 have a better heat stabiiity than emulsions with natural woolwax, they 20538~

have a softer consistency, a good adhesion and leave a pleasant feeling on the skin. According to this brochure, SOFTiSAN 649 is particularly suitable for skin care products, baby creams, sticks and other decorative cosmetics. The brochure gives formulations of several products 5 containing SOFTISAN 649, amongst which there is included a sports cream stick on page 5.
Cosmetic cover compositions containing mineral oil and lanolin are known, and such compositions may not be ideally suitable for consumers who have oily skin andtor are sensitive to lanolin. These 10 consumers would benefit from a composition that was free of mineral oil and free of lanolin, and they would further benefit if such a composition could also absorb some excess oil from the user's skin. Thus, a cosmetic cover composition free of mineral oil and free of lanolin, which could also absorb some excess oil from the user's skin, would be a 15 welcome contribution to the art. Such a contribution is provided by this invention.

SUMMARY OF THE INVENTION

This invention provides a cosmetic composition, useful as a cover composition, which is tree of mineral oil and free of lanolin.
These compositions contain certain esters which can completely replace mineral oil in cosmetic cover compositions. Suitable esters useful as a mineral oil substitute are those which have mineral oil-like properties --i.e., suitabl0 esters impart to the composition or provide the composition with characteristics which are the same as or similar to those characteristics which would have been impar~ed to or provided by mineral oil if the mineral oil had been present in the composition.
The compositions of this invention ars also free of lanolin.
Thesq compositions contain triglyceride (glyceryl esters of fatty acids) which can completely replace lanolin in cosmetic compositions.
Suitable triglycerides useful as a lanolin subsitute are those triglycerides which have lanolin-like properties -- i.e., suitable triglycerides impart to the composition or provide the composition with characteris~ics which are the same as or similar to those characteristics which would have been imparted to or provided by lanolin if the lanolin had been present in the composition The compositions of this invention also contain distarch phosphate which, without wishing to be bound by theory, is believed to function as an absorber of oil from the skin of the user.
The compositions of this invention also contain at least one wax, triglyceride, bulking agent, colorant, and optionally, preservative.
The term "at least one" as used herein means one, more than one, or a 1 0 mixture.
The term "suitable for use in cosmetic compositions", as used herein, means cosmetically acceptable and refers to those materials known in the art as being useable in cosmetic compositions, such as those materials disclosed in Nikitakis, J.M., editor, ~
Cosmetic Ingredient Handbook, First Edition, copyright 1988, published by The Cosmetic, Toiletry and Fragance Association, Inc., 1110 Vermont Avenue, N.W., Washington, D.C., 20005, the disclosure of which is incorporated herein by reference thereto, and which is hereinafter referred to as the ~CTFA Handbook."

This invention provides a cosmetic composition free of mineral oil and free of lanolin comprising:
(A) an effective amount of at least one wax suitable for use in cosmetic compositions;
(B) an effective amount of at least one triglyceride suitable for use in cosmetic compositions;
(C) an effective amount of a mixture of esters suitable for use in cosmetic compositions, said mixture comprising:

(i) an effective amount of a mixture of esters with said mixtura (i~ having a ==

4 20~38~5 maximum acid value of 0.5 and a saponificaiton value of 268-288; and (ii) an effective amount of a mixture of esters with said mixture (ii) having a maximum acid value of 0.5 and a saponification value of 206-266;

(D) an effective amount of distarch phosphate;
(E) an effective amount of at least one bulking agent suitable for use in cosmetic compositions;
(F) an effective amount of at least one colorant suitable for use in cosmetic compositions; and (G) optionally, an effective amount of at least one praservative suitable for use in cosmetic compositions.
This invention also provides articles of manufacture comprising the compositions of this invention manufactured in a solid rigid form suitable for use as a cosmetic. Preferably the compositions are manufactured in the form or shape of a cover stick.
Although the compositions can be formed by known procedures into any suitable solid shape for the ultimate end product, preferably the composition is formed into a cosmetic stick shape -- e.g., a cylindrical shape having a slanted tip such as a "lipstick shape." The shaped composition can then be placed in any suitable dispensing package such as a lipstick type container wherein the composition is advanced by, for example, turning the barrel of the dispensing package or container. Thus, for example, the composition can be cylindrical in shape wherein the cylinder is about 6.3 to about 7.6 cm in length and preferably about 6.8 to about 7.1, the diameter is about 0.72 to about 0.77 cm with about 0.73 to about 0.75 being preferred, and the tip of the cyclinder is formed so as to have an angle of about 43 to about 47 degrees and preferably about 44 to about 46 degrees.
The compositions of this invention contain an effective amount of at least one a cosmetically acceptable wax. Waxes which 20~3855 may prove useful include those listed in the CTFA Handbook cited above and already incorporated herein by reference thereto. Thus, representative examples include ozokertie, ceresin, paraffin, candelilla, carnauba, and the like. Preferably the wax is selected from the group 5 consisting of: ozokerite and ceresin. Most preferably ozokerite is used.
Usually, the wax is present in amounts of about 10.0% to about 15% by weight of the total composition with about 13% to about 14% by weight being preferred.
The compositions of this invention also contain an effective 10 amount of at least one cosmetically acceptable triglyceride. Triglyceride, as used herein, refers to the glyceryl esters of fatty acids and includes those esters which have been hydrogenated to reduce or eliminate unsaturation. Those skilled in the art will appreciate that th triglycerides are the chief constituent of fats and oils, and that the 15 triglycerides have the general formula:

CH2(00CR1 )CH(OOCR2)CH2(00CR3) wherein R1, R2 and R3 are usually of different chain lengths, e.g., C1-20 C31 and more usually C2-C24. Fatty acids are well known in the a~, see for example, ~i~ch~ cals rganic Compounds for Research ~
ni~nostic Reagents, Sigma Chamical Company, pp 924-925, 1989, the disclosure of which is incorporated herein by reference thereto.
Thus, the triglycerides which are useable include those 25 materials (substances) which are known to those skilled in the art as fals and oils. Suitable triglycerides which may prove useful include, those materials listed as fats and oils in the CTFA Handbook cited above and already incorporated herein by reference thereto. Preferably, triglycerides are used rather than a fat or oil containing triglycerides.
30 Representative triglycerides include the glyceryl esters of caprylic aci~
capric acid, isostearic acid (identified in the CTFA Handbook as a mixture of branched chain 18 carbon aliphatic acids), adipic acid, laur;
acid and stearic acid.

-6- 20~385~

The preferred fatty acids are selected from the group consisting of caprylic acid, capric acid, isostearic acid and adipic acid.
Preferably a mixture of the glyceryl esters of the above mentioned preferred fatty acids are used. The preferred ester mixture normally 5 contains, by weight of the ester mixture, about 10 to about 14 % glyceryl ester of caprylic acid, about 7.0 to about 11.0% glyceryl ester of capric acid, about 39.0 to about 41.0 % glyceryl ester of isostearic acid, and about 17.0 to about 21.0% glyceryl ester of adipic.
The preferred triglyceride is caprylic/capric/isostearic/
10 adipic triglyceride which is identified by the CTFA Handbook as the mixed ester of caprylic, capric, isostearic acids with a dimer of glycerin.
Caprylic/capric/isostearic/ adipic triglyceride is commercially available under the product designation SOFTISAN 649 from Huls American, Inc., Rockleigh, N.J. SOFTISAN 649 is reported to contain: 12% caprylic 15 acid, 9/O capric acid, 19% adipic acid, 41% isostearic acid, and 10% 12-hydroxystearic acid with the remainder being a mixture of C6, C12, C14 and C16 fatty acids.
Other triglycerides which may prove suitable include:
caprylic/capric/lauric trigiyceride; caprylic/capric/linolaic triglyceride;
20 caprylic/capriclstearic triglyceride; and caprylic/carpic triglyceride.
These triglycerides are known In the art --see the CTFA Handbook for example.
Normally, the triglyceride is used in amounts of about 3 to about 10% by weight of the total composition with about 4 to about 5%
25 by weight being preferred and about 5 to about 6% by weight being most preferred.
The compositions of this invention, as stated previously, contain no mineral oil. In place of the mineral oil there is used an effective amount of a mineral oil substituts. The minerai oil substitue 30 provides the same or similar characteristics to the composition that mineral oil would have provided had the mineral oil been present. It is contemplated that one or more esters having mineral oil characteristics or imparting mineral oil lika characteristics to the composition, may be used.

=~

7 20~38~5 An effective amount of a mixture of esters may be used as a mineral oil substitute in the compositions of this invention. Thus, an effective amount of a mixture of esters comprising:

(i) an effective amount of a mixture of esters with said mixture (i) having a maximum acid value of 0.~ and a saponification value of 268-288; and (ii) an effective amount of a mixture of esters with said mixture (ii) having a maximum acid value of 0.5 and a saponification value of 206-266 may be used in the compositions of this invention.
The ratio of ester mixture (i) above to (ii) above is normally about 1.5 to about 1 with about 1 to about 1 being preferred. Thus, (i) and (ii) are each usually present in the amounts of about 15 to about 25% (about 30 to about 50% total of (i) plus (ii)) by weight of the total composition with about 17 to about 23% (about 34 to about 46% ~otal of (i) plus (ii)) being preferred and about 18 to about 22% (about 36 to about 44% total of (i) plus (ii)) being most preferred and about 19 to about 21% (about 38 to about 42% total of (i) plus (ii)) being even more preferred.
Tridecyl trimellitate (TDTM) can be blended with at least one other ester, preferably at least two other esters, to formulate a blend which duplicates the viscosity and feel of mineral oil for use in cosmetics. The esters generally blended with TDTM will be lower in viscosity than TDTM. The preferred esters for blending with TDTM are tridecyl stearate (TDS), neopentylglycol dicaprylate/dicaprate (NPGC) and dipentaerythritol hexacaprylatelhexacaprate (DPHC). Particularly advantageous results are achieved when TDTM is blended with TDS, NPGC and DPHC. The selection and quantity of the esters which are 2053~

blended with TDTM will vary depending on the desired viscosity of the final blend and the feel which the final blend is intended to have.
Illustrative, non-limiting examples of other esters which may be blended with TDTM are isodecyl trimellitate, isopropyl myristate, 5 isopropyl palmitate, tridecyl myristate, tridecyl palmitate, isodecyl trimellitate, propylene glycol dicaprate/dicaprylate, neopentyl glycol dicaprat~ and trisodecyl trimellitate.
Depending on the desired viscosity and other properties desired, the amount of TDTM in a particular bland can vary from about 5 10 to about 85 wt%, based on the ester blend, preferably about 5 to about 60 wt%, more preferably about 8 to about 45 wt %, most preferably about 10 to about 38 wt%, e.g., about 12 to about 37 wt%. Whsre the ester blend is a low viscosity blend, e.g., 70 S.S.U. at 100 F., the TDTM
is preferably utilized at about 10 to about 14 wt%. For an intermediate 15 viscosity blend, e.g., 130 S.S.U. at 100 F., the TDTM is prefarably u~ilized at about 33 to about 38 wt% based on the ester blend, and for a high viscosity blend, e.~., 350 S.S.U. at 100 F., the TDTM is preferably utilized at about 38 to about 42 wt%, based on the ester blend. The balance of the ester blend can be at least one additional ester, 20 preferably at least two additional esters, each of the two esters being utilized at about 2 to about 60 wt% based on the ester blend depending on the particular properties desired. In a preferred blend where TDS is one of the two or more additional esters blended with the TDTM, it can be utilized at about 5 to about 55 wt%. Where the ester blend is a low 26 viscosity blend, e.g., less than 150 S.S.U., the TDS is preferably utilized at about 40 to about 60 wt%, more preferably about 42 to about 46 wt%, based on the ester blend. Where the ester blend is a higher viscosity blend, the TDS is preferably utilizied at about 5 to about 20 wt%, more preferably at about 5 to about 12 wt%, most preferably at about 6 to 30 about 9 wt % based on the ester blend.
Where NPGC is one of the additional esters, it is preferably utilized at about 2 to about 65 wt% based on the ester blend. For lower viscosity blends, the NPGC is preferably utilized at about 40 to about 50 wt% based on ~he ester blend, more preferably about 42 to about 45 20~3855 g wt%. For higher viscosity blends, the NPGC is preferably utilized at about 2 to about 10 wt%, more preferably about 3 to about 5 wt%.
Where DPHC is one of the additional ester blends it can be utilized at about 10 to about 55 wt%. For lower viscosity blends the 5 DPHC is preferably utilized at about 12 to about 25 wt% based on the ester blend, more preferably at abou~ 16 to about 20 wt%, most prefarably at about 17 to about 19 wt% based on the ester blend. For higher viscosity blends, the DPHC is preferably utilized at about 40 to about 55 wt% based on the ester blend, more preferably about 42 to 10 about 52 wt%, most preferably about 46 to about 50 wt%.
These blends are known in the art, for example, see U.S.
