Abstract
A liquid deodorant for topical application to the skin contains a 47% to 87% by weight solution of propylene glycol in water as the sole deodorant active principle, optionally together with a volatile non-aqueous carrier. The solution may be in the form of a roll-on, a pump-spray or a pressurised spray.
Description
The present invention relates to liquid deodorant compositions comprising a mixture of water and propylene glycol as the sole deodorant active principle. More particularly, the invention is directed to liquid deodorant compositions containing a mixture of propylene glycol and water
In a non-aqueous solvent, preferably comprising ethanol or isopropanol, which are suitable for dispensing In the form of an aerosol spray, a pump spray or a roll-on liquid.
Commercial liquid deodorant compositions generally comprise a deodorant active principle, a humectant such as propylene glycol or glycerol and a carrier liquid such as water or ethanol. Such compositions broadly fall into one of three types or classes based upon deodorant active principle. In the first class are the popular anti-perspirant compositions containing astringent Inorganic salts of aluminium, zinc and zirconium asrthe antiperspirant/deodorant active principle. The second class of deodorant compositions contain germicides or antibacterial agents such as cetyl trimethylammonium bromide, trichlorosalicylanilide, hexachlorophene, chlorohexidine, trichlorohydroxy diphenyl ether and the like. This class of deodorants acts by inhibiting the growth of bacteria and other microorganisms which apparently give rise to body odour by decomposition of skin debris and the perspiration itself. The third class of deodorant composition relies upon a variety of other non-astrigent compounds, such as sodium bicarbonate and zinc ricinoleate as the deodorant active principle.
One of the primary shortcomings of using anti-persirant compositions based upon astringent metal salts Is that staining and rotting may occur on the clothing in contact with the surface to which the composition is applied. For example, these salts can sometimes cause a white or coloured deposit to form on clothing which Is not removed when the clothing is laundered in normally washing, Further, these deposits on the clothing have
2.
S447O been known to lead to disintegration of the fabric itself. Other disadvantages of using astringent salts are that they can cause an unpleasant stinging sensation in some users and they chemically interfere with the natural bodily process of sweat production to control body temperature. Deodorants based upon germicides also tend to stain clothing and thereby exhibit one of the disadvantages of the deodorants based on astringent salts. Finally, deodorants based upon sodium bicarbonate or zinc ricinoleate tend to exhibit stability problems.
Based upon the foregoing discussion, we continued research in the hope of finding a deodorant active principle which is an effective deodorant, does not stain, is compatible with other Ingredients common to deodorant compositions and can be formulated to yield products which are stable, i.e. devoid of separation or precipitation. Such research has led to the discovery that mixtures of water and propylene glycol in specific proportions are effective deodorants. Such discovery is surprising in view of the fact that propylene glycol is commonly employed in anti-perspirant and deodorant compositions. For example, 3% to 10% by weight of propylene glycol has been employed as a humectant in anti-perspirant and/or deodorant sticks, liquids and creams. Also, U.S. Patents Nos. 2,890,087, 3,943,242 and 4,137,306 disclose anti-perspirant or deodorant sticks containing 35% to 85% by weight of aqueous propylene glycol. Finally, Russian Patent No. 507,323 discloses a mixture of a major proportion of propylene glycol with minor proportions (1-2%) of urotroplne and polyvinylpyrrolidone as an anti-perspirant or deodorant active principle. However, to date the prior art has failed to recognize that aqueous propylene glycol alone is an effective deodorant.
We have now discovered that it is possible to control body odour by topically applying to the skin a liquid deodorant composition comprising an effective amount of a mixture of 47% to 87% by weight of propylene glycol and water as the sole deodorant active principle. Optimum deodorant efficacy is noted when an aqueous mixture containing 64% to 82% by weight of propylene glycol is employed as the sole deodorant active principle.
Broadly, the liquid deodorant compositions of the present invention comprise 10 to 100 parts by weight of an aqueous propylene glycol
3.
j _ 54470 containing 47% to 87% by weight of propylene glycol and 0 to 90 parts hy weight of a compatible, non-aqueous, non-toxic, volatile, organic, liquid carrier, preferably, comprising ethanol or isopropanol. Such compositions usually are single-phase liquids which are stable and safe to use.
Preferred compositions are liquids suitable for application in the form of a pressurized spray, pump spray or roll-on consisting essentially of the 47-87% aqueous propylene glycol as sole deodorant active principle and either ethanol or isopropanol, with the weight ratio of the said alcohol to the aqueous propylene glycol being from 1:3 to 3:1. More specifically, the active principle will represent 30 to 75 parts by weight of the said mixture of propylene glycol and water in a pump spray, 23 to 75 parts hy weight of the said mixture of propylene glycol and water in a roll-on liquid, and 11 to 44 parts hy weight of the said mixture of propylene glycol and water in a pressurized spray. A pump spray and a roll-on will desirably both contain 25 to 50 parts hy weight of alcohol, the weight ratio of alcohol to the said mixture being from 1:3 to 3:1, the total weight of the composition being 100 parts. Also, the pressurized spray will include a liquified, normally gaseous propellant.
A pressurized spray will desirably contain 9 to 43 parts by weight of alcohol, the weight ratio of alcohol to the said mixture being from about 1:3 to 3:1 and 45 to 80 parts hy weight of dimethyl ether, the said composition being a single-phase liquid, the total weight of the composition being 100 parts.
One preferred form of pressurized spray consists essentially of 11 to
44 parts hy weight of the said mixture of propylene glycol and water, 0.5 to 5 parts hy weight of a water-in-oil emulsifier and 51 to 88.5 parts by weight of a compatible non-aqueous, non-toxic, volatile, organic liquid carrier which further includes a liquified, normally gaseous hydrocarbon or halohydrocarhon propellant, the said composition forming a stable, oll-in-water emulsion of the said aqueous propylene glycol In the said non-aqueous solvent, the total weight of the composition being 100 parts.
4.
In the most preferred compositions, the active deodorant principle will be 64% to 82% aqueous propylene glycol.
As stated above, the invention herein i3 based upon the discovery that aqueous mixtures of propylene glycol in the range of 47% to 87% by weight of propylene glcyol are effective to prevent human perspiration odour when used as the sole deodorant active principle. Optimum deodorant effectiveness is achieved with aqueous propylene glycol having a concentration of 64% to 82% by weight or propylene glycol.
Propylene glycol (1,2-propanediol) has the formula CH^CHCOlDCHgOH and is commonly used as a humectant or solvent in cosmetic compositions.
It is a colourless, odourless liquid having a slightly sweet taste and it is completely miscible with water and most organic solvents. Propylene glycol is produced commercially by the hydration of propylene oxide obtained through the intermediate propylene chlorohydrin.
The aqueous propylene glycol mixtures are readily obtained by admixing the requisite proportions of water and propylene glycol. Such solutions can be prepared at room temperature either by adding propylene glycol to water or by adding water to propylene glycol.
Generally, the liquid deodorant composition will comprise from 10 to 100 parts by weight of the propylene glycol-water mixture containing 47% to 87% by weight of propylene glycol as the sole deodorant active principle.
In the most preferred compositions, the propylene glycol-water mixture will contain 64% to 82% by weight of propylene glycol.
The other major component of the deodorant composition Is a volatile organic liquid carrier in which the mixture of water and propylene glycol is either soluble or Insoluble, with the soluble carriers being preferred. Such organic liquid carrier also must be both chemically non-reactive with the aqueous propylene glycol and non-toxic to humans.
Examples of volatile compounds which can function as carriers include both polar and non-polar type compounds. Suitable polar compounds are ethanol, n-propanol, isopropanol and tertiary butanol, with ethanol and
.
4 4 7 0 isopropanol being preferred. Satisfactory non-polar compounds Include Cj-C^q paraffinic hydrocarbons having a boiling point in the range of 35 C to 175 C, cyclic dimethyl siloxanes of the formula [ (CHj^SiO]* wherein x is an integer from 3 to 6, low molecular weight poly dimethyl siloxanes of the formula (CH,)-SiO[(CH,) .-SiO Si(CH )_] or 3 3 3 2 y 3 3
CH^)^ wherein y is an integer from 0 to 4 and liquid, normally gaseous hydrocarbon and halohydrocarhon propellants. Examples of suitable hydrocarbons are n-hexane, heptane, octane and mixtures thereof. Examples of liquified normally gaseous propellants are dimethyl ether, C^-C^ hydrocarbons, e.g. propane, n-butane and isobutane and mixtures thereof, and halohydrocarbons, e.g. dichlorodifluoromethane, monochlorodifluoromethane, dichlorotetrafluoroethane, trichlorofluoromethane, trichlorofluoroethane, difluoroethane, difluoromonochloroethane, trichlorotrifluoroethane, monofluorodichloromethane, monofluorodichloroethane, pentafluoromonochloroethane, cyclic hexafluorodichlorobutane, octafluoropropane, cyclic octafluorobutane and mixtures thereof. Dimethyl ether is a preferred propellant in pressurized spray compositions because it forms single-phase liquids in the presence of water. On the other hand, hydrocarbon propellants and halohydrocarhon propellants can be employed where the pressurized composition is in the form of a water-in-oil emulsion.
Generally, the proportion of the volatile organic liquid carrier will be in the range of 0 to 90 parts by weight of the deodorant composition in which aqueous propylene glycol is the sole deodorant active principle. However, the preferred proportion of volatile carrier varies with the form of the final product as described below and the form of the final product may be a pressurized liquid spray, a liquid pump spray or a roll-on liquid. Further, regardless of the form of the final liquid product, the vehicle of the preferred compositions comprises either ethanol or isopropanol in a weight ratio to the aqueous propylene glycol mixture in the range of about 1:3 to 3:1.
In the liquid roll-on composition, the proportion of the mixture of water and propylene glycol usually ranges from 23 to 75 parts by weight
6.
4 4 7 0 and, preferably, from 50 to 65 parts by weight, provided that the amount of water In the composition does not exceed a maximum of about 40 parts by weight of the final product. The balance of the composition will be the volatile carrier which comprises about 25 to 50 parts by weight, preferably
to 45 parts by weight, of ethanol, and/or isopropanol In a weight ratio of ethanol or isopropanol to aqueous propylene glycol in the range of 1:3 to 3:1.
In the liquid pump spray composition, the mixture of water and propylene glycol usually ranges from about 26 to 74 parts by weight and, preferably, from 30 to 60 parts by weight, provided again that the amount of water does not exceed about 402 by weight of the final product. Again, the balance of the composition is the volatile carrier comprising preferably 25 to 50 parts by weight of ethanol and/or Isopropanol in a weight ratio to the mixture of water and propylene glycol In the range of
1:3 to 1.7:1.
The liquid pump spray and the liquid roll-on compositions may be prepared in the form of clear or opaque liquids, but the clear liquids are preferred because stability problems are minimized. Further, small amounts of known thickening agents may be Included to increase the viscosity of the liquids. For example, thickening may be achieved by adding from 0.5% to 5% by weight of a carboxy vinyl polymer, e.g. Carbopol (Trade Mark) 934 and 941, hydroxypropyl cellulose, methyl cellulose or carboxy methyl cellulose.
In the pressurized liquid spray the proportion of the mixture of water and propylene glycol usually ranges from 12 to 43 parts, preferably 20 to 30 parts, by weight, provided that the amount of water does not exceed a maximum of about 20 parts by weight. The balance of the composition will be the volatile carrier which comprises 8 to 43 parts by weight of ethanol or isopropanol and 45 to 80 parts by weight of a
3Q liquified, normally gaseous propellant. Again, the weight ratio of ethanol or isopropanol to the mixture of water and propylene glycol will range from 1:3 to 3:1. Further, generally when the propellant is other than dimethyl ether, the pressurized liquid will be in the form of a water-in-oil emulsion which requires the presence of 0.5% to 5.0%,
7.
Β 4 4 7 υ preferably 0.75% to 4%, by weight of a water-ln-oll emulsifier such as propylene glycol stearate, glyceryl monostearate, sorbitan monolaurate, sorbltan monooleate, polyglycerol oleate sorbitan sesquioleate and mixtures of the foregoing, with sorbitan sesquioleate being preferred.
In addition to the foregoing essential components of the composition of the present invention, one may include therein from 0.1% to 2% hy weight of components such as perfumes, colouring agents and the like, so as to improve the aesthetic value and consumer acceptability thereof.
Compositions according to this invention will he used In a conventional manner using containers of normal design and delivering the usual quantities of product.
Where the product dispensed as a pressurized spray is in the form of a water-in-oil emulsion, generally the water-In-oil emulsifier will be dissolved in the ingredients comprising the liquid oil phase with the exception of the propellant and the mixture of water and propylene glycol will be added slowly thereto with agitation to form a water-ln-oll emulsion which is subsequently mixed with propellant in a known fashion.
The liquid compositions of the present invention cause less staining of fabrics in contact therewith as compared with deodorant compositions containing low concentrations of either an astringent salt such as aluminium chlorohydroxide or an antibacterial compound containing a quaternary ammonium group in. its molecular structure such as chlorohexidine or cetyl pyridinium chloride. Also, less fabric degradation or fabric rotting is noted when, the compositions of the present invention are employed as compared with some prior art formulations. Furthermore, the compositions of the present invention, containing ethanol or isopropanol form a film on the skin which is not objectionably wet despite the presence of water and which provides a desirable cool effect upon initial contact due to the balanced proportions of water and monohydric alcohol.
Additionally the compositions of the present invention are mild to the skin because of the absence of the prior art irritating astringent salts and antibacterial agents.

EXAMPLES 3Α to 3D
The deodorant efficacy of the following compositions were clinically evaluated by panelists under actual use conditions:
A. Water 5 B. 60% propylene and 40% water (60% PG) C. 30% propylene glycol, 20% water and 50% ethanol (30% PH/50% E) D 50% of aluminium chlorohydroxide and 50% water (50% ACH)
In this deodorant efficacy test a panel of 56 persons was divided into four groups. During the first week panelists were furnished with a placebo soap and were permitted to wash under their arms as frequently as desired, but no anti-perspirant or deodorant product was used. Beginning with the second week, each panelist visited the evaluation centre in the morning where the odour of each of the left and right axilla was self-evaluated using an odour assessment scale of one (very weak) to nine (very strong). After odour assessment, the panelist applied four metered shots of the test product, i.e. about 0.6 ml of product, to each axilla. The panelists returned five hours later for an assessment of the odour level. This routine was continued during the next two weeks.
The means scores were determined for each product based upon fifteen days of use and are reported in Table III.

The foregoing results show that a pump spray deodorant composition containing 60% propylene glycol solution (Example 3B) provides the same deodorant efficacy as a pump spray containing 50% of aluminium chlorohydroxide (Example 3D), the most common active component employed in anti-perspirant compositions. The pump spray containing equal parts of 60% propylene glycol and ethanol also was an effective deodorant, but its effectiveness was not as great as the other pump sprays presumably because the use concentration of the active principal, i.e. 60% propylene glycol, was really only one half the concentration of the 60% PG product. It would seem likely that equivalent effectiveness for the 30% PG/.50% E product (Example 3C) could he achieved by applying 1.2 ml of the said product to each axilla so that the amount of aqueous propylene glycol applied would be the same for the 60% PG product (Example 3B).
As indicated, the compositions according to the present invention can take the form of propellant based liquids for dispersing from an aerosol pressurized container or as propellant free liquids or emulsions or lotions or gels either for spraying with the aid of a finger operated pump or for dispensing from a roller-ball applicator directly onto the skin.
