ABSTRACT:
TECHNICAL FIELD
The present invention pertains to the control of perspiration, and in particular to a lotion which prevents sweat from forming on the surface of the skin.
BACKGROUND ART
Antiperspirant compositions for controlling sweating are well known in the art. For example U.S. Pat. No. 3,981,986 shows zirconium-aluminum-polyol buffered antiperspirant water soluble complexes. The complexes are satisfactory for use in any of the wide variety of conventional antiperspirant forms, including lotions, creams, roll-ons, hydro-alcoholic aerosol sprays, power-in-oil sprays, as well as manually pumped hydro-alcoholic sprays. U.S. Pat. No. 4,434,155 illustrates basic aluminum bromide compositions and methods useful as astringents or antiperspirants. The invention is superior to the conventional aluminum chlorhydroxide or basic aluminum chloride in that it is compatible with conventional aerosol propellants, and requires little additional treatment or modification before incorporation into an antiperspirant composition. U.S. Pat. No. 4,666,710 discloses antiperspirant compositions including 30% by weight of aluminum chlorhydrate, 68% by weight of ethanol, and 1.5% by weight of a long chain fatty acid, myristic acid. The invention contains relatively high levels of ethanol to promote quick drying after application to the skin, and which have good levels of antiperspirant efficacy.
As useful as the aforementioned antiperspirant compositions may be, they are not effective against excessive perspiration. Many people suffer from hyperhidrosis, which in simple terms, can be defined as overly active sweat glands stimulated by the sympathetic branch of the autonomic nervous system. This is the part of the nervous system which releases perspiration throughout the body. This is the body's natural method of cooling itself down during active periods or exposure to warm conditions. A person with hyperhidrosis experiences uncontrolled sweating and/or blushing. Those who suffer from this condition are faced with major challenges every day, and find it difficult to interact socially. They are often afraid to shake hands or perform any task which would bring them into close contact with others. First impressions play an important role in our society and in the work place. A wet clammy handshake can leave a poor and lasting impression. This can be very detrimental during that important meeting, job interview, ultimately hindering your career and relationship with others. Other symptoms of hyperhidrosis are:
General:
Washing or wiping hands constantly
Hiding hands under the dinner table
Fear of touching another person or holding hands
Exchanging money or other items in public
Avoiding manicures or pedicures
Difficulty with a neck tie
Difficulty wearing make-up
Wet hair, eyes burning due to sweat
Handling or smudging of papers
Uncomfortable playing a musical instrument
Unable to swing a golf club or baseball bat
Anxiety, difficulty concentrating
Industrial:
Problems caused by prolonged use of work gloves
Handling tools and heavy objects
Health Industry:
Nurses and Doctors who suffer from reactions caused by surgical gloves
Sports:
As the body heats up during physical activities, sweat is produced. This can cause problems with the ability to handle balls and other sports equipment.
DISCLOSURE OF INVENTION
The present invention is directed to a novel solution to the aforementioned afflictions of hyperhidrosis. The present invention comprises a lotion that when applied to the skin, penetrates the skin's surface causing an invisible barrier. This invisible barrier keeps sweat from forming on the skin's surface, keeping it dry and comfortable for hours. The lotion protects the hands like a“liquid glove”. Advantages of the composition of the present invention are that it quickly dries, and distributes over the skin evenly. Additionally, all the ingredients in the present invention are FDA approved, so it can be used safely and with confidence.
In a preferred embodiment the lotion of the present invention is a composition of the following ingredients:
a. denatured ethyl alcohol;
b. hydrophobic silica;
c. a monoethyl ester of the copolymer of methyl vinyl ether and maleic anhydride in ethanol;
d. iso-octahexacontane;
e. octamethylcyclotetrasiloxane; and,
f. hydroxypropylcelluose.
In another preferred embodiment, the octamethylcyclotetrasiloxane is replaced by decamethylcyclopentasiloxane.
Other features and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.
