Abstract
The disclosed lubricating suppository is formulated to have properties advantageous for coital use, including extraordinary water washability. The ingredients and phase relationships of the suppository composition provide a high degree of compatibility with water and with naturally-occurring vaginal moisture. The suppository composition contains a glyceride lubricant and can be lubricious with or without the presence of moisture. The suppository, which is solid at room temperature but melts in a short time at body temperature, is made by dissolving, for example, 10-30 parts by weight of high-HLB (e.g. >14) nonionic surfactant in 50-70 parts by weight of a molten, water-soluble polyoxyethylene glycol component and by dispersing or emulsifying 10-20 parts by weight of the glyceride (e.g. a triglyceride of C.sub.6 -C.sub.18 aliphatic carboxylic acids) included in the composition. In use, the suppository can be inserted prior to coitus and permitted to melt to a liquid, which is lubricious even in the absence of moisture, but still has the aforementioned extraordinary water washability.
