ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to aqueous gel compositions comprising an odor controlling agent for deodorizing skin surfaces. Articles of manufacture and methods of deodorizing the skin using disclosed compositions are also disclosed.
BACKGROUND OF THE INVENTION
Today's consumers are well acquainted with the notion of germs and germ transmission. Daily, people come into contact with germs at eating establishments, the gym, while changing diapers or using portable toilet facilities (e.g., portapotties). Once in contact with human hands, these germs (i.e., micro-organisms such as bacteria, fungus and/or viruses) are quickly passed from individual to individual and, thus, contribute to the spread of contagious and/or infectious diseases. One of the best and easiest ways of preventing such germ and/or disease transmission is by routinely and conscientiously wash one's hands. Recognizing the inconvenience or impossibility of such hand washing under certain traveling conditions and/or time constraints, a number of manufactures have introduced hand sanitizing products which sanitize skin surfaces without the need for water and/or towels.
Although current hand sanitizing products kill the germs associated with such routine activities as gasing up automobiles, changing diapers or handling exercise equipment, they can fail to eliminate their attendant malodors (e.g., gasoline odors). Moreover, malodor can arise from activities not normally associated with germ transmission (e.g., odors from food preparation such as onion, garlic etc.). Thus, the need exists for developing products which not only kill germs associated with daily activities but also which eliminate attendant malodor. The present inventors have found that aqueous, skin sanitizing compositions comprising select sanitizing agents and an odor controlling agent provide excellent antimicrobial activity as well as improved odor control.
Therefore, an important aspect of the present invention is to provide improved skin deodorizing compositions.
Another aspect of the present invention is to provide skin sanitizing compositions comprising an odor controlling component and select sanitizing agents.
These and other aspects will become readily apparent from the detailed description which follows.
SUMMARY OF THE INVENTION
The compositions of the present invention relate to stable, preferably translucent, more preferably clear, skin sanitizing and deodorizing compositions, comprising:
a.) an effective amount to provide odor control benefit of an odor controlling agent, preferably selected from the group consisting of cyclodextrin, water soluble metallic salt, zeolites, soluble carbonate and/or bicarbonate salts, water soluble ionic polymers, silica gel, silica molecular sieves, activated alumina, kieselguhr, fullers earth, montmorillonite, smectite, attapulgite, bentonite, palygorskite, kaolinite, illite, halloysite, hectorite, beidellite, nontronite, saponite, hormite, vermiculite, sepiolite, chlorophyll, soda lime, calcium oxide, chitin, potassium permanganate, activated charcoal or activated carbon, and mixtures thereof;
b.) an effective amount to provide sanitizing benefit of a select sanitizing agent prefably selected from the group consisting of an alcohol antiseptic an antimicrobial, and mixtures thereof;
c.) optionally, from 0 to about 10% of thickener;
d.) optionally, from 0 to about 10% of emollient;
f.) optionally, from 0 to about 1% of perfume; and
g.) water.
In one aspect of the present invention, gel compositions are preferred. The present invention also relates to methods of using the personal cleansing compositions. The present invention further relates to an article of manufacture comprising the skin sanitizing and deodorizing composition incorporated into a preferably clear dispensing container.
One preferred skin sanitizing and deodorizing composition of the present invention comprises:
a.) an effective amount of an odor controlling agent to provide odor control benefit;
b.) from about 40% to about 99% of an alcohol antiseptic;
c.) optionally, from 0 to about 10% of a water-soluble metallic salt;
d.) optionally, from 0 to about 10% of a thickener;
e.) optionally, from 0 to about 10% of an emollient;
f.) optionally, from 0 to about 1% of perfume; and
g.) water.
Another preferred skin sanitizing and deodorizing gel composition of the present invention comprises:
a.) an effective amount of odor controlling agent to provide odor control benefit;
b.) an effective amount of sanitizing agent comprising antimicrobial agent to kill or reduce the growth of microorganisms;
c.) from 0.01% to about 10% of thickener;
d.) optionally, from 0 to about 10% of emollient;
e.) optionally, from 0 to about 1% of perfume; and
f.) water.
The present invention also relates to stable, preferably translucent, more preferably clear, skin deodorizing gel compositions, comprising:
a.) an effective amount of odor controlling agent to provide odor control benefit;
b.) from 0.01% to about 10% of thickener;
c.) optionally, from 0 to about 1% of perfume;
d.) optionally, from 0 to about 10% of emollient;
e.) optionally, from 0 to about 0.2% of antimicrobial preservative; and
f.) water.
DETAILED DESCRIPTION OF THE INVENTION
The skin sanitizing and deodorizing compositions of the present invention can comprise, consist of, or consist essentially of the essential elements and limitations of the invention described herein, as well any of the additional or optional ingredients, components, or limitations described herein.
All percentages, parts and ratios are based upon the total weight of the personal cleansing compositions of the present invention, unless otherwise specified. All such weights as they pertain to listed ingredients are based on the active level and, therefore, do not include carriers or by-products that may be included in commercially available materials, unless otherwise specified.
By the term “alcohol antiseptic” as used herein, means an alcohol (or combination of alcohols) which is effective, at the concentration employed, to kill or reduce the growth of microorganisms, for example, bacteria, with which it comes in contact.
By the term “instant” as used herein means the compositions of the present invention disinfect the skin area within about 5 minutes, preferably within about 1 minute, more preferably within about 30 seconds, and even more preferably within about 20 seconds, without the need for soap and water.
The term “safe and effective amount” as used herein means an amount of a compound or composition sufficient to significantly induce a positive benefit, preferably an odor controlling and antimicrobial benefit, including independently the benefits disclosed herein, but low enough to avoid serious side effects, i.e., to provide a reasonable benefit to risk ratio, within the scope of sound judgment of the skilled artisan.
Preferably, the sanitizing and deodorizing composition of the present invention is clear. The term “clear” as defined herein means transparent or translucent, preferably transparent as in “water clear,” when observed through a layer having a thickness of less than about 10 cm.
The skin sanitizing compositions of the present invention, including the essential and optional components thereof, are described in detail hereinafter.
Essential Components
Odor Controlling Agent
An essential ingredient of the present invention is the odor controlling agent. The phrase “odor controlling agent,” as used herein, comprises material or materials which, individually or when formulated into the compositions of the present invention, serve to bind or entrap malodor molecules onto or into their molecular structures, or chemically react with malodor molecules such that the malodor molecule goes undetected by most (if not all) olfactory senses. Examples of suitable odor controlling agents include, but are not limited to, cyclodextrin, water soluble metallic salt, zeolites, soluble carbonate and/or bicarbonate salts, water soluble ionic polymers, silica gel, silica molecular sieves, activated alumina,
