Abstract
ABSTRACT
This invention relates to a method for the preparation of an anti-perspirant deodorant composition in the form of a compressed cylindrical pel-let (hereafter referred to as compressed powder stick). In this method a powdered mixture of talc, aluminum chlorhydroxide, magnesium stearate, kaolin, calcium carbonate, rice starch and glycine is compressed between 600 and 3,000 p.s.i. using a hydraulic press. The resulting product exhibits remark-ably high "pay-off" characteristics and strength (against breakage).

Description
106B2~5 This invention relates to a method for the preparation of a powdered anti-perspirant deodorant composition in the form of a compressed cylindrical stick, having a dome shape at one end of the cylinder. This invention also includes within its scope the resulting anti-perspirant deodorant compressed powder stick.
Anti-perspirant compositions have been used to inhibit perspiration as well as provide deodorant properties to the human body. Heretofore these compositions have been available in the form of aqueous sprays, roll-ons, gel sticks, creams and the like. These compositions are generally quite unsatis-factory to use because they have the tendency to stick to the clothing. InBritish Patent 996,560, there is described an an~i-perspirant and deodorant composition in the form of a dry stick. Such a composition, while represent-ing some improvement over previously known forms, is still not quite satis-factory because: 1. The stick is too brittle or fragile if compressed according to the patent (60 - 150 p.s.i.). 2. The ingredients are not readily released upon rubbing on the body surface area, if compressed at higher pressure (1000 - 3000 p.s.i.) in order to reduce the brittleness.
The term "pay-off" used herein and in the specification and in the claims denotes the phenomenon in which compressed powder in stick form will release the ingredients under gentle friction. For example, a good "pay-off"
would indicate that the powder stick, when applied under gentle pressure, will release the ingredients evenly and provide a good protective coating `
upon the body surface area.
According to the present invention, there is provided a method for the preparation of an anti-perspirant and deodorant composition in stick form and exhibiting high "pay-off" and strength, which process comprises mixing together an anti-perspirant chosen from aluminum chloride, aluminum sulphate and aluminum chlorhydroxide and mineral oil as a first blend; rice starch and water as a second blend; and talc, perfume, kaolin, an inorganic stearate `30 chosen from magnesium stearate, zinc stearate and calcium stearate, glycine, calcium carbonate, and a deodorant agent as a third blend; mixing the three blends together; and thereafter compressing the resulting mixture at a '~''`'~ ~
pressure of between 600 psi and 3,000 psi to form a unitary powder stick, the amounts of components used in the three blends, and the amounts of each blend taken for compression being sufficient to provide in the unitary powder stick an amount of each component both falling within the following percentage weight ranges and ~otalling to 100%:
talc: 5% to 25% aluminum chlorhydroxide: 20% to about 77.8%
magnesium stearate: 5% to 20% kaolin: 1% to 10%
calcium carbonate: 1% to 5% rice starch: 10% to 40%
mineral oil: 0.0% to 1.0% water: 0.0% to 3.0%
glycine: 0.1% to 5.0% perfume: 0.001% to 1.0%
deodorant agent: 0.01% to 1.0%
To enhance consumer acceptance, small amounts of fragrance such as perfume varying between 0.0001 to 1% may also be included.
In a typical practice of this invention, the aforementioned ingred-ients are blended together until an homogeneous mixture is obtained. To the blended mixture a small amount of water is added followed by further mixing to ensure proper mixture. Typically, the ingredients are passed through a suitable blender such as a Fitzmill* fitted with a suitable screen so that ` the resulting powder will exhibit uniform particle size. The powder is then fed into a dome-shaped mold about 1.5" in diameter and about 3 to 4" in height. A pressure of at least 600 to 3,000 p.s.i. is applied to the powder for about 10-30 seconds, compressing the powder into a stick, about 1.5" in ,. .
`~ diame~er and about l.l" in height, which is readily released fromthe mold.
~ In a modified practice the powder is compressed directly onto a :, :
supporting round disk which has a conical cross-shaped insert for holding ~; the stick.

The three blends are then combined and mixed until homogeneous. The powder is then compressed as mentioned above.
We have found the use of magnesium stearate or its equivalent such as zinc stearate or calcium stearate essential to control the "pay-off"
which is further illustrated in the following example.
Furthermore, we have also found the use of rics starch, or other finely powdered starch, essential to impart strength or binding to the compressed stick, without impairing the "pay-off" of the product.
A commonly used deodorant compound such as 2,4,4'-trichloro-2'-hydroxy-diphenyl ether may be included in the formulation to broaden the spectrum of the resulting composition.
It may also be desirable to include other doedorant compounds with a view to reducing odor-forming bacteria on the skin. These include, for example, 2,2'-thio-bis-(4,6-dichlorophenol) or bis-3,4,6-trichloro-2-hydroxy- -~
phenyl) methane in an amount of 0.1 to 10% depending upon the ingredients selected to be included in the formulation.
As described above, the present composition includes glycine.
The inclusion of glycine is advantageous because it acts as a buffer to neutralize the acid formed through the hydrolysis of the aluminum-containing antl-perspirant compound.
The invention will now be illustrated by way of the following examples.

The water is sprayed into the rice starch, and the wet rice starch passed through a Fitzmill*. All other ingredients are blended together and passed through a Fitzmill*.
The three blends are then combined and mixed until homogenous.
About 32.0 grams of the resulting powder is compressed into dome-shaped sticks by utilizing a mold about 1.5" in diameter and about 3 - 4" in height at a pressure of about 2,000 p.s.i. After holding the pressure at 2,000 p.s.i. for about 20 seconds, there is obtained a unitary anti-perspir-and composition exhibiting exceptional "pay-off" and strength. To further increase the strength of the stick, the powder may be compressed directly onto a supporting disk which has a conical cross shaped insert for holding the stick.
