Abstract
A B S T R A C T
The present invention relates to a method for the preparation of liquid antiperspirant and deodorant compo-sitions in a non-aqueous to a low level aqueous vehicle. This method comprises mixing together at high speed and shear 20%
to 60% by weight of an aluminum salt and 0.1% to 5% by weight ?
of Bentone gel, 0.5% to 5% by weight of sorbitan monooleate, 1% to 10% by weight of a metalic stearate and 1% to 5% by weight of silicone dioxide in a vehicle comprising poly-dimethylcyclosiloxane alone or in admixture with alcohol and water until a homogeneous suspension is obtained, in which the polydimethylcyclosiloxane may vary between 5% to 80% by weight, the isopropanol between 0% to 40% by weight, the ethanol between 0% to 20% by weight, the water between 0% to 10% by weight, and the isopropylmyristate between 1% to 20% by weight. The active ingredients in resulting product remain in suspension over extended period of time. When it is applied over the body area, it exhibits remarkably fast-drying properties.

Description
This inven-tion relates to a method for -the prepara-tion of liquid antiperspirant and deodorant compositions character-ized by non-sticky and fast-drying properties when applied to the body area. In addition, -the ac-tive ingredients remain in suspension for extended periods of time. This invention also includes within its scope, the resulting liquid antiperspirant deodorant compositions.
PRIOR ART
Antiperspirant compositions which may contain option-ally deodorant compounds have been used to inhibit perspiration,as well as,to provide deodorant or antimicrobial properties to the human body. These compositions have been available in the form of aqueous sprays, creams and roll-ons. Alrnost all of these prior art antiperspirant compositions contain either water or water in admixture with alcohol. One of the major draw-backs of these conventional water and/or alcohol based roll-on anti~ersFirants is that they "feel wet and stickyl', and take a relatively long time to dry wher. applied to -the underarm.
Some aqueous antiperspirant compositions containing water insolukle ir~gredients have a tendency to separate upon storage, which make the products cosrnetically unattractive.
THE IN~ENTION
According to the present invention, there is provided a method for the preparation of a non-aqueous to a low level aqueous alcoholic liquid antiperspirant and deodorant compos-i-tion. The composition comprises as antiperspirant compounds in the form of finely divided particles. Typicall~ these are aluminum salts for example aluminurn chloride, aluminum hydroxy bromide, aluminum sulphate and aluminum chlorhydroxide.
Aluminum chlorhydroxide is micronized dry form, for example from 0.1 to 50 microns are particularly preferred. The selected ~}~
.,~
antiperspirant compound is dispersed in polydimethylcyclo-siloxane. This silicone vehicle is available under a variety of trademarks. The produc-t identified as Volatile Silicone 7207 by Union Carbide is particularly preEerred. Alternatively, a mixture of alcohol for example methanol, ethanol, isopropyl with a small amount of water may be used as the vehicle. Thus, a typ-ical vehicle may contain up to 80% silicone, the remaining being alcohol.
Generally speaking, from about 20% to 60% by weight of the antiperspirant compound may be used; preferrably about 40% by weight.
To this suspension about 0.1% to 5% by weight and preferrably 1.2% by weight of a suspending agent for example, organic derivatives of magnesium aluminum silicate minerals such as Bentone~is added. Bentone is available commercially in gel form as a 10~ suspension in isopropyl myristate. Ben-tone~ acts as the suspending agent for the par-ticles.
To stabilize the suspension, a combination of sorbi-tan monooleate, a metalic stearate and silicone dioxide are added. Typically~ from 0.5% to 5% and preferrably 4% by weight of sorbitan morlooleate and from about 1% to 10% by weight of a metalic stearate for example magnesium stearate and preferrably 5% by weight are added thereto.
About 1.0% to 5% by weight oE silicone dioxide avail-able as Cab~o Sil~ and preferrably 1% by weight is utilizecl.
The amount of the above ingredients may vary dcpend;ng upon the particular formula-tion but is within the described range.
The mixture is made into a homogeneous dispersion in a high speed and high shear mixer.
In a commercial embodiment, the above composition is filled into suitable containers such as glass or plastic D9~ ~
bottles. A commercially available "ball-applicator" is then attached to the top of such a container. The ball may have a diameter of 2.4 to 3.6 cm and rotates freely within a sleeve or collar.
In use, the consumer inverts the bottle, the ball applicator is then coated with the product which can be readily applied to areas such as the underarm or bringing the ball applicator in contact with the skin.
The above described product may optionally contain other ingredients such as deodorants, antimicrobials, emollients buffering agents and fragrances. A commonly used deodorant compound such as 2,4,4'-trichlor-2'-hydroxy-diphenyl-ether may be included in the formulation to broaden the spectrum of the resulting composition. Other deodorants which may be used include, for example, 2,2'-thio-bis~'4,6-dichlorophenol or bis-3,4,-6-trichloro 2-hydroxy-phenyl benthane in an amount effective to reduce odor forming bacteria on the skin. Buffer-ing agents such as glycine in the amount of about 0% to 5~ by weiyht may optionally be incorporated.
The invention will now be illustrated by way of the following examples.
-A homogeneous suspension is prepared, using high speed, high shear mlxing, from the following ingredients:
