Problems solved by technology

High molecular weight waxes can also become brittle and, if the absorbent article is to be bent and flexed, can also cause the absorbent article to shatter or crumble into pieces due to lack of flexibility

Abstract

Absorbent devices, and more particularly absorbent devices that are worn interlabially by female wearers for catamenial purposes, incontinence protection, or both, that have a emollient composition on their body-contacting surface are disclosed. The interlabial device has a body-contacting surface that is pre-moistened or pre-treated with an emollient to prevent drying of the wearer's labial tissue and to reduce friction of the structure against the wearer's labial tissue. The absorbent device is preferably capable of maintaining contact with the inside surfaces of the wearer's labia majora when worn. The emollient composition comprises a plastic or fluid emollient such as mineral oil, petrolatum and / or polysiloxane, an immobilizing agent such as a fatty alcohol or wax to immobilize the emollient on the body-contacting surface of the device, and optionally a hydrophilic surfactant to improve wettability of the coated surface. Because the emollient is substantially immobilized on the surface of the absorbent device, less emollient is required to impart the desired therapeutic or protective emollient coating benefits.

Description

field of invention [0001] The present invention relates to absorbent articles worn between the labia for menstrual absorption, incontinence protection, or both. More particularly, the present invention relates to an absorbent interlabial device which is premoistened or pretreated with an emollient for improved comfort. Background of the invention [0002] Various types of absorbent articles and various modes of absorption are known for absorbing bodily exudates such as menses, urine and faeces. For feminine hygiene products, there are two basic types: sanitary napkins which have been developed to be worn externally around the vulva and built-in tampons which have been developed to be placed in the vaginal cavity to stop menstrual flow there. Such tampon supplies are described in U.S. Patents 4,412,833, issued November 1, 1983 to Weigner et al., entitled "Tampon Inserter" and to Jacobs, issued November 8, 1983, entitled US Patent 4,413,986 for "Tampo...
