Definitions

  • compositions of this invention are substantially anhydrous and contain one or more polyhydric alcohol.
  • This invention also relates to the method that can be used to test and compare the irritation of the compositions of this invention and other personal lubricants known to the art. Unlike previously-known compositions that use exothermic reactions to generate warmth or use irritants to convey a perception of warmth, the compositions of this invention use "heat of solution" to generate warmth. The feeling of warmth generated by the compositions of this invention is very pleasant and mild in comparison with previously-known compositions.
  • compositions of this invention are also more lubricating to tissue than previously-known warming compositions. Furthermore, the lubricity of the compositions of this invention increases upon dilution with water; the lubricity of previously-known aqueous compositions tends to decrease upon dilution with water. In actual use, therefore, the compositions of this invention will be considerably more lubricating than those previously known to the art.
  • Humans are warm-blooded animals that maintain a constant body temperature of 98.6°F (37°C) .
  • Human skin and external organs have a very efficient circulatory and nervous system with the result that the human body can very quickly perceive changes in temperature.
  • Personal lubricants and medicaments are usually applied to humans' mucous membranes at room temperature, i.e., between at 60°F and 80°F. Because there is an appreciable difference in temperature between room temperature and human body temperature, users of such lubricants and medicaments perceive them to be quite cold. This feeling of cold can be quite uncomfortable for the user. From time to time, attempts have been made to develop products that overcome this perception of cold.
  • compositions range from jellies to liquids to vaginal suppositories and vary from being aqueous to oils to silicone based.
  • the majority of the compositions actually used today are aqueous jellies or aqueous liquids.
  • Most personal lubricants known and available for use today are cold to touch, a feeling that can be uncomfortable .
  • compositions are known to the trade or described in the literature that claim to impart a warming sensation upon application to the skin or mucosa. These compositions generally fall into a few main categories based upon mechanism of action.
  • compositions use plant extracts which are irritating to the skin and mucous membranes and give a feeling or perception of warmth by virtue of their irritant action.
  • Others claim to enhance blood flow in order to cause tissue warming.
  • Still others are alleged to work on the principle of freezing point depression and are well suited for heating in a microwave or cooling in a refrigerator.
  • warming compositions use plant extracts or agents, such as methyl salicylate, that are irritating to the skin or mucous membranes.

  • Another category of warming products utilize the mechanism of increased blood circulation.
  • WO 200260408 Al relates to anhydrous cosmetic hair care compositions containing inorganic salts such as sodium sulfate, calcium sulfate, aluminum sulfate, calcium chloride, magnesium chloride or calcium oxide, or magnesium sulfate. Upon mixing with water, these compositions generate heat.
  • KR20010227018 describes exothermic cosmetic containing active zeolite compositions that promote blood circulation and metabolism by giving warm-sense to the skin. Active zeolite contains ethoxylated alcohol.
  • JP63159490A relates to exothermic cosmetic compositions especially for softening hair containing reducing agents such as sodium sulphite, sodium thiosulphate, sodium pyrosulphite or sodium hydrogen sulphite and an oxidizing agent such as sodium bromate, potassium bromate or sodium perbromate.
  • reducing agents such as sodium sulphite, sodium thiosulphate, sodium pyrosulphite or sodium hydrogen sulphite
  • an oxidizing agent such as sodium bromate, potassium bromate or sodium perbromate.
  • EP2001306347 refers to compositions for use in preparing hair for shaving.
  • the compositions contain at least one substance that undergoes a discernible chemical change when mixed during shaving.
  • the substance changes temperature, emits a scent or undergoes oxidation, hydration, an acid-base reaction or an exothermic reaction.
  • US 20020142015 Al and JP 2002179517 A describe warming compositions for cosmetics, toiletries, bath additives and pharmaceuticals that contain a cooling agent and a specific p-hydroxybenzaldehyde derivative. The use of this p-hydroxybenzaldehyde cooling agent is intended to product a warming effect for a longer duration.
  • FR2810240 Al describes cosmetic compositions containing a component that can absorb or release heat thereby providing a cooling and refreshing effect during exposure to heat or a warming effect during exposure to cold, such as a combination of long chain hydrocarbon compounds that can absorb thermal energy and store or exchange heat .
  • US3632516A describes a self-heating lather that is rapidly heated by hydrogen peroxide via a thiosulphredox reaction.
  • US 20020142015 Al and JP 2002179517 A describe warming compositions for cosmetics, toiletries, bath additives and pharmaceuticals that contain a cooling agent and a specific p-hydroxybenzaldehyde derivative.

  • US3632516A describes a self-heating lather that is rapidly heated by hydrogen peroxide via a thiosulphredox reaction.
  • JP2001335429 describes gel-like cosmetics that contain 40-75% by weight of polyethylene glycol, 20-55% by weight of glycerol and carboxyvinyl polymer. These compositions are used for generating heat for promoting blood circulation and metabolism in fatigue conditions and to provide warm feeling during shaving.

  • U.S. Patent No. 4,110,426, entitled "Method of Treating Skin and Hair with a Self Heated Cosmetic, Organic Boron-Oxygen-Boron Compounds” describes non-aqueous compositions such as shaving creams, that are rendered self-heating by including therein a compound containing at least one boron-oxygen-boron linkage, such as triethoxyboroxine .
  • the boron-containing compound reacts exothermally with water or other protic material to increase temperature.

  • the gels and jelly compositions of this invention are more lubricating than even aqueous lubricant products currently available on the market.
  • the compositions of this invention, in particular, the jelly compositions of this invention are novel in that their lubricity increases upon dilution with water.

This is a particular advantage in that the compositions of this invention may be used in connection with moist vaginal or oral mucosa and will become increasingly lubricious upon exposure to the moisture therein.
  • anhydrous compositions are ordinarily perceived to be irritating to the skin and mucous membranes
  • the gel and jelly compositions of this invention are surprisingly non-irritating.
  • compositions of this invention may be applied to the skin or mucous membranes, preferably the vaginal or oral mucosa.
  • the compositions of this invention are preferably substantially anhydrous and preferably contain at least one polyhydric alcohol.
  • polyhydric alcohols contained in the compositions of this invention come into contact with water or body moisture in humans, they react with the ambient water molecules to cause an increase in temperature or generate warmth, thus having a soothing effect on the tissues to which these compositions are applied.
