Benefits of technology

[0023] The present invention provides a spreadable warming lubricant that exhibits excellent spreadability and low surface tension and contact angle, thereby providing a well-wetted, uniform, thin layer during skin to skin contact and condom latex film to skin contact. The warming lubricant composition has sufficient viscosity to establish easily a thin film on either skin or condom latex film with a film thickness ranging from 0.01 to 0.1 mm. The spreadable warming lubricant composition i...

Problems solved by technology

Therefore, the quantity of the warming lubricant desirably is limited to the quantity of moisture available during use.
When the interior and exterior of a latex condom is not coated with a lubricant, there is rubbing between skin and latex, which produces friction and irritation.
Incorporation of lubricant on a condom latex surface as a u...

Embodiment Construction

[0027] The present invention provides an improved warming lubricant that provides and maintains a thin elastohydrodynamic lubricating film between skin and either skin or latex. The lubricant exhibits excellent spreadability due to sufficient viscosity, a low surface tension, and a low contact angle. The lubricant is substantially anhydrous, preferably containing less than about 5% water, more preferably containing less than about 3% water, and most preferably containing less than about 2% water, such as less than about 1% water. Having sufficient viscosity, a film thickness ranging from about 0.01 to 0.10 mm, such as about 0.05 to 0.10 mm, can be achieved on skin or latex rubber.

[0028] Accordingly, the present invention provides a spreadable warming lubricant comprising glycerin with another polyhydric alcohol and a non-ionic surfactant. Preferably, glycerin is present in an amount from about 40% to 60%, the polyhydric alcohol is present in an amount from about 40% to 60%, and the...

Abstract

A substantially anhydrous, spreadable warming lubricant composition comprising a mixture of glycerin, a polyhydric alcohol, and a non-ionic surfactant, the viscosity of the composition being less than that of glycerin but greater than that of the polyhydric alcohol, thereby promoting formation of a useful thin layer on a surface with which the composition is brought into contact, the surfactant improving wetting and spreadability of the composition on skin and latex, such that the composition can be applied to skin or a condom and provide an optimal warming effect upon contact with ambient moisture during use and such that the composition can be added to a condom package and, over the course of about a week, spread and coat nearly the entire internal and external surfaces of the condom.

Description

FIELD OF THE INVENTION [0001] The present invention relates to personal lubricants, which are highly spreadable on latex rubber and human skin and which provide a lubricious warming effect upon contact with moisture. BACKGROUND OF THE INVENTION [0002] Lubricants have been employed for a number of applications, including lubrication of latex condoms and lubrication of skin. More recently, lubricants have been designed to take advantage of the heat that is generated when glycerin or propylene glycol is dissolved in water. Unfortunately, glycerin and propylene glycol do not spread readily on skin and other surfaces and irritate skin after prolonged use, since glycerin extracts water from the skin surface. The spreadability of such lubricants is further compromised by the addition of one or more insulating agents, such as honey, isopropyl myristate and / or isopropyl palmitate, which reportedly help to retain the heat of the lubricant (see, e.g., U.S. Pat. App. Pub. Nos. 2004 / 0138074, 200...
