Description
~2&~8~23 COSMETIC STICKS
Patrick Columkille McCall BACKGROUND OF_THE INVENTION
The present inventis~n relates to stick-type cosmetic 5 compositions. More particularly, it relates to improved antiperspirant sticks.
The chemical and cosmetic literature is replete with formu-lations of stick-form cosmetics for various uses, such as antiperspirants, deodorants, and lipsticks. The specific stick 10 formulation may vary depending upon such factors as the intended use, the "active" ingredient to be incorporated, and the part of the body to which the product is to be applied.
There are three main types of such cosmetic stick formu-lations: compressed powder sticks, gel sticks, and wax sticks.
15 While each of these formulation types may have advantages in certain use situations, each also has disadvantages. For example, compressed powder sticks are often brittle and hard, and leave a cosmetically-unacceptable dust upon application. Gels may be unstable due to evaporation of alcohol or ( in antiperspirant 20 sticks) due to interaction of astringent metal salts with the soaps present. Wax-based ~ormulations can also yield cosmetically-unacceptable products due to such factors such as hardness, greasiness, and stickiness.
The use of powders and particulates has been disclosed in 25 the literature in order to modify the cosmetic and formulation characteristics of stick-type products. For example, polyethylene in a powder base has been disclosed for use in stick-form powder cosmetics in Japanese Patent specification 57-109,706, published .luly 8, 1982. Similarly, U.S. Patent 4,379,136, Mochida, issued 30 April 5, 1983, discloses polyethylene as a binding aid in compressed powder cosmetic sticks. Inert powders, such as poly-~; styrene, have also been used in gel stick formulations, as dis-closed in U.S. Patent 3,255,082, Barton, issued June 7, 1966.
Powder materials are discloseci in a matrix of Insoluble alcohols 35 and volatile silicone oils, so as to form wax-based cosmetic sticks, ; ~ ~

~8423 in U.S. Patent 4,126,679, Davy, et al., issued November 21, 1 978.
_ It has now been discovered that gel or wax-based stick cosmetic compositions, containing certain chemically inert particula .es of a defined size and of low density, have superior application and in-use characterics when compared to similar cosmetic sticks not having such particles. In particular, wax cosmetic sticks of this invention incorporating astringent metal salts have improved application characteristics, such as "glide", as well as improved in-use characteristics, such as tackiness and appearance.
SUMMARY OF THE INVENTION
The present invention provides solid cosmetic stick composi-tions comprising:
(a) one or more liquid base materials:
(b) a solidifying agent of a type and amount effective to solidify said iiquid base materials; and ~c) from about 296 to about 30~ (by total composition volume) of chemically inert particles of at least about 10 microns in diameter and having a density less than about 0.60 g/ml.
The liquid base materials are typically present at levels of from about 109~ to about 90~ (by total composition weight), and the solidifying agent is typically present~at levels of from about 3~6 to about 70~ (by total composition weight). This invention also provides cosmetic sticks, further comprising from about 10~ to about 70~6 (by weight) of one or more astringent metallic salts, particularly useful as antiperspirants.
DESCRIPTION OF THE INVENTION
The cosmetic sticks of this invention contain three essential ingredients: liquid base materials, solidifying agents, and chem-ically inert particles of a defined size and of low density. These compositions (herein "cosmetic sticks"~ encompass any solid (or semi-solid) composition intended for human use in order to deposit material on human tissue. Thus, the instant cosmetic sticks preferably contain additional ingred~ents, dependlng upon th~lr , ,. ; ..
intended use, such as antiperspirant salts and deodorizing com-pounds. These essential and optional ingredients must be "cosmetically-acceptable", i.e., safe for human~ use and aesthetically acceptable at the levels at which such materials are 5 used in the present compositions, at a reasonable risk/benefit ratio .
Specifically, the cosmetic sticks of the present invention comprise:
[a) one or more liquid base materials:
(b) a solidifying agent of a type and amount effective to solidify said liquid base materials; and ~c) from about 296 to about 3096 (by volume) of chemically inert particles olF at least about 10 microns in diameter and having a density less than about 0.60 g/ml.
The liquid base materials are typically present at levels of from about 10~ to about 90~ (by weight). The solidifying agent is typically present at levels of from about 396 to about 7096 (by weight). (As used herein percentages "by volume" are with respect to totai composition volume; percentages "by weight" are with respect to total composition weight. In addition, such percentages "by volume" of the chemically inert particulates are determined with respect to the actual volume occupied by the particulates in the final composition, as a function of the weight and the true density of the particular particuiate materiai used. ) These cosmetic sticks can be generally described as being either gel sticks or wax sticks, depending upon the particular liquid base materials and solidifying agent used. The preferred levels of the components of these sticks will, accordingly, vary depending upon the type of stick desired. Further, the specific liquid base materials and solidifying agents, as well as the preferred materials, will vary according to the type of stick and the desired rheologic properties.
Essential Components Liquid Base Materials:
The cosmetic sticks of this invention contain one or more liquid materials, herein "liquid base materials", that form the base matrix of the solid stick when combined with a suitable solidifying 126~3~23 agent.

The present inventis~n relates to stick-type cosmetic 5 compositions. More particularly, it relates to improved antiperspirant sticks.
The chemical and cosmetic literature is replete with formu-lations of stick-form cosmetics for various uses, such as antiperspirants, deodorants, and lipsticks. The specific stick 10 formulation may vary depending upon such factors as the intended use, the "active" ingredient to be incorporated, and the part of the body to which the product is to be applied.
There are three main types of such cosmetic stick formu-lations: compressed powder sticks, gel sticks, and wax sticks.
15 While each of these formulation types may have advantages in certain use situations, each also has disadvantages. For example, compressed powder sticks are often brittle and hard, and leave a cosmetically-unacceptable dust upon application. Gels may be unstable due to evaporation of alcohol or ( in antiperspirant 20 sticks) due to interaction of astringent metal salts with the soaps present. Wax-based ~ormulations can also yield cosmetically-unacceptable products due to such factors such as hardness, greasiness, and stickiness.
The use of powders and particulates has been disclosed in 25 the literature in order to modify the cosmetic and formulation characteristics of stick-type products. For example, polyethylene in a powder base has been disclosed for use in stick-form powder cosmetics in Japanese Patent specification 57-109,706, published .luly 8, 1982. Similarly, U.S. Patent 4,379,136, Mochida, issued 30 April 5, 1983, discloses polyethylene as a binding aid in compressed powder cosmetic sticks. Inert powders, such as poly-~; styrene, have also been used in gel stick formulations, as dis-closed in U.S. Patent 3,255,082, Barton, issued June 7, 1966.

DESCRIPTION OF THE INVENTION
The cosmetic sticks of this invention contain three essential ingredients: liquid base materials, solidifying agents, and chem-ically inert particles of a defined size and of low density. These compositions (herein "cosmetic sticks"~ encompass any solid (or semi-solid) composition intended for human use in order to deposit material on human tissue. Thus, the instant cosmetic sticks preferably contain additional ingred~ents, dependlng upon th~lr , ,. ; ..

These essential and optional ingredients must be "cosmetically-acceptable", i.e., safe for human~ use and aesthetically acceptable at the levels at which such materials are 5 used in the present compositions, at a reasonable risk/benefit ratio .
Specifically, the cosmetic sticks of the present invention comprise:
