Waterless Lotion and Lotion-Treated Substrate
First Claim
1. A wet-laid cellulosic tissue, said tissue bearing a microemulsion composition comprising an antiviral compound, said microemulsion composition being liquid at room temperature and undergoing a phase change to a semi-solid or solid upon contact with said wet-laid cellulosic tissue, said antiviral compound being chosen from the group consisting of:
- bioflavonoids;
dicarboxylic acids;
alpha hydroxy carboxylic acids;
neem seed oil;
sandalwood oil;
protease inhibitors and mixtures thereof.

Abstract
A lotion includes a micro-emulsion composition, which is liquid at room temperature and undergoes a phase change to a semi-solid or solid upon contact with a substrate. The micro-emulsion composition can include a polar emollient, a non-polar emollient, a non-ionic surfactant, and a co-surfactant. The invention also includes a substrate treated with the lotion.

7. A sheet of lotioned tissue comprising a wet laid cellulosic substrate formed by the process of providing:
- said wet-laid cellulosic substrate, applying a lotion having micro-emulsion phase to said wet-laid cellulosic substrate in the amount of between about 0.1% and 25% by weight of the dried cellulosic substrate, the composition of said lotion upon application lying in the micro-emulsion phase and being liquid at room temperature and undergoing a phase change to a semi-solid or solid upon contact with said wet-laid cellulosic substrate, said lotion comprising a polar emollient;
a non-polar emollient, a fatty alcohol and a non-ionic surfactant, said lotion being in finely divided, semi-solid form dispersed upon the fibers of the wet-laid cellulosic substrate. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
