Definitions

  • the present invention relates to novel compositions of matter suitable for use as detergent creams and has particular reference to pressurized shaving cream compositions suitable for packaging under pressure in a dispensing device commonly known as an aerosol dispenser;
  • Such preparations have employed, in general, soaps, i.e. water-soluble salts of higher fatty acids, e.g., lauric, myristic, palmitic, stearic acids, etc., as the principal deterging or cleansing agent.
  • soaps i.e. water-soluble salts of higher fatty acids, e.g., lauric, myristic, palmitic, stearic acids, etc.
  • the shaving creams which have enjoyed the greatest amount of commercial success have utilized certain water soluble soaps of stearic and palmitic acids together with minor amounts of coconut oil fatty acids as the detergent. These soaps provide products which exhibit high water solubility, have excellent deterging properties, and form a rich and attractive lather.
  • ammonia soaps, triethanolamine soaps, etc. when employed in sole combination with a propellant in an aqueous medium, provide products which form relatively large amounts of foam within the container and correspondingly smaller amounts of the desired liquid product.
  • a smooth evoluation of lather is no longer obtainable.
  • the product is dispensed in the form of bubbles rather than in the form of a smooth, rich lather. This prevents the product from being delivered smoothly from the container, decreases the self-propelling properties of the propellant, and causes undesirable quantities of the product to remain unrecoverable from the container.
  • a further disadvantage of pressurized shaving creams employing triethanolamine soaps as the sole detergent is that the lather remaining within the delivery spout of the container, after each dispensing operation, continues to expand in volume and soon overflows and runs out the openingof the spout. 4
  • v cellent pressurized shaving cream compositions can be prepared by employing a' mixture comprising certainwater soluble soaps of higher fatty acids as a-detergent,.
  • Such a detergent when dispersed in an aqueous solvent medium with a liquefied normally gaseous propellant, provides a product which may be delivered smoothly from the container in the form of a rich, stable lather which does not readily collapse after discharge from the container and subsequent exposure to the atmosphere.
  • the novel pressurized shaving cream compositions of the present'invention are adapted for convenient usein commercially available aerosol. dispensing containers from which practically all of the product may be dispensed.
  • the soaps i.e., the water-soluble salts of higher fatty acids, which comprise the detergents used in accordance with the present invention are well known in the art and.
  • ammonium soaps, etc. may be prepared by reacting the basic material directly with previously derived higher.
  • fatty acids elg., palmitic, stearic acid, etc.
  • Sodium and potassium soaps may be prepared in a similar manner or by reacting sodium or potassium hydroxide with fats, oils, greases, etc. Any of the oils and fats used in detergent processing, such as coconut oil, palm kernel oil, tallow, palm oil, etc. may be usedindividually .or in mixtures as fractionated fatty acids or blends thereof,
  • the concentration of the detergent employed in thev soaps to the sum of the alkali metal soaps present in the detergent should be within the range of about 1.2 to 2.5.
  • the alkali metal soap fraction should contain at least 3.5 times as much potassium soap as sodium soap.
  • the aqueous solvent medium of the compositions of the present invention is requisite for the preparation offla shaving cream having desirable lathering properties. It has been found that water (tap water, distilled water, deionized water, etc.) possesses adequate solubility for the detergent and the required dispersibility with the In general, relatively small amounts of lower molecular weight.
  • aliphatic alcohols preferably lower monohydric alcohols, e.g.,
  • methanol, ethanol, normal propanol, isopropanol, etc. may be admixed with the. water. Any concentration of alcohol may be used, the only requirement being that the aqueous solvent medium as prepared be sufficient to;
  • the alcohol should not be present in an amount which will adversely affect the lathering properties of the finished product.
  • the amount of the aqueous solvent medium employed generally should amount to at least usually about 70 to about 90%, and preferably about of the total Weight.
  • any suitable liquefied, normally gas-- eous, organic material may be used.
  • said -material should be. substantially non-toxic, non-inflamr Patented Oc t. 13, 1959 that ex- 3 ma ble, low-boiling, odorless, etc.
  • Suitable propellants include liquefied, normally gaseous, low molecular weight halogenated hydrocarbon materials, such as halogenated methane, ethane propane, butane, and mixtures thereof. Satisfactory products result from, the use of such mate: rials in view' of their high volatility under usual atmospheric conditions, their stability in and dispersibility' with theaqueous medium, employed, etc.
  • halogenated hydrocarbon propellants which have been found. to be particularly suitable for use in accordance with the present, invention include monochlorodifluoromethane, monochlorodifiuoroethane, dichloromonofiuoroethane, dichlorodifluoromethane, dichlorotetrafluoroethane, trichloromonofluoromethane,difluoroethane, etc.
  • it may be desirable to use a. combination of two or more of the liquefied normally gaseous materials as a propellantin order to achieve a suitable pressure within the container and impart the desired properties of stability, propellancy, ease of delivery, etc., to the shaving cream compositions.
  • the amount of propellant may be varied. depending upon the. properties desired in the final product. In general,.it: need only be present in an amount sufficient to satisfactorily propel or eject the shaving cream from the container in the form of a smooth lather. It has been found, however, that at least about 5% and preferably about..7'% to. about propellant, by weight of the total shaving. cream composition, should be used although higher amounts maybe employed if desired, e.g., up to about

The mixture is heated to about 130 F'. andstirred until the soaps are dissolved. Thereafter, the mixture is cooled to about 90 F. and any moisture loss made up by the introduction of addit-ional water. The mixture thus prepared is placed in a pressure container.
  • the contents are cooled by suitable means to a temperature of 5 about 5.5 parts of cooled and liquefied propellant comprising approximately 60% dichlorotetrafluorethane (Freon 114) and 40% dichlorodifluoromethane (Freon 12) are then added to the contents after which the container is sealed.
