Abstract
The application of active ingredients, exemplified by GML, to absorbent fibers, such as rayon fibers, used in tampon manufacture at very low levels has been found to maintain efficacy in the inhibition of the production of toxic shock syndrome toxin one (TSST-1) produced by S. aureus without overtly killing the microorganism to achieve the desired reduction while avoiding undesired test results that suggest the presence of “impurities” in some jurisdictions.
Claims16
An absorbent article comprising:
- a) a fibrous absorbent structure
- b) a cover substantially enclosing the fibrous absorbent structure and having disposed thereon up to about 5 wt-% of the active ingredient
- c) an active ingredient selected from the group consisting of:
- i) monoesters of a polyhydric aliphatic alcohol and a fatty acid containing from eight to eighteen carbon atoms and wherein said monoester has at least one hydroxyl group associated with its aliphatic alcohol residue;
- ii) diesters of a polyhydric aliphatic alcohol and a fatty acid containing from eight to eighteen carbon atoms and wherein said diester has at least one hydroxyl group associated with its aliphatic alcohol residue;
- and
- iii) mixtures of said monoesters and diesters;
- and
- wherein the fibrous absorbent structure
- A) has disposed thereon up to about 0.05 wt-% of the active ingredient
- B) contains less than 0.3% ether soluble substances according to the Ether Soluble Substances Test,
- C) contains less than 0.7% water soluble substances according to the Water Soluble Substances Test;
- and
- D) passes the Foaming Test.

An absorbent article comprising:
- a) a fibrous absorbent structure comprising multilimbed fibers;
- b) a sufficient amount of an active ingredient disposed on the multilimbed fibers which is effective to inhibit the production of toxic shock syndrome toxin-1 by Staphylococcus aureus bacteria when said product is exposed to said bacteria;
- c) a cover substantially containing the fibrous absorbent structure,
- wherein the active ingredient is selected from the group consisting of:
- i) monoesters of a polyhydric aliphatic alcohol and a fatty acid containing from eight to eighteen carbon atoms and wherein said monoester has at least one hydroxyl group associated with its aliphatic alcohol residue;
- ii) diesters of a polyhydric aliphatic alcohol and a fatty acid containing from eight to eighteen carbon atoms and wherein said diester has at least one hydroxyl group associated with its aliphatic alcohol residue;
- and
- iii) mixtures of said monoesters and diesters;
- and
- wherein the active ingredient is present at less than about 0.1 wt-% of the fibrous absorbent structure.
