Method to produce a tampon that inhibits exoprotein production from gram positive bacteria
A method to inhibit the production of exoproteins from Gram positive bacteria, such as harmful proteins produced by Staphylococcus species, is described. The method is particularly useful to inhibit the production of TSST-1, alpha-toxin and/or enterotoxins A, B and C from Staphylococcus aureus bacteria. The method is based on exposing Gram positive bacteria to alkyl polyglycoside incorporated into an absorbent product. Alternate methods include bringing Gram positive bacteria into contact with the alkyl polyglycoside in other forms, e.g., when formulated with a pharmaceutically acceptable carrier or incorporated in or on a non-absorbent substrate. Typically, the alkyl polyglycoside has a hydrophilic/lipophilic balance (HLB) of at least about 10 and an alkyl group with an average of 8 to 14 carbon atoms.
1. A method to produce a tampon that inhibits the production of exoprotein from Gram positive bacteria located in and around the vagina, the method comprising:
treating a porous nonwoven sheet formed from hydrophobic polymer with a liquid vaginal cleansing composition comprising a pharmaceutically acceptable carrier and alkyl polyglycoside to produce cover sheet material with at least 5 add-on wt. % alkyl polyglycoside having the general formula:
H-(Z) n -O—R
wherein Z is a saccharide residue having 5 or 6 carbon atoms, n is 4–6, and R is an alkyl group having 8 to 18 carbon atoms;
wherein the alkyl polyglycoside has a hydrophilic/lipophilic balance of 10 to 15; and
forming said tampon comprising an absorbent material, at least a portion of which is covered by the cover sheet material.
2. The method of claim 1 , wherein the alkyl polyglycoside has an alkyl group having from 8 to 14 carbon atoms.
3. The method of claim 1 , wherein the alkyl polyglycoside has an alkyl group having from 8 to 10 carbon atoms.
4. The method of claim 1 , wherein the alkyl polyglycoside has a hydrophilic/lipophilic balance of 12 to 14.
5. The method of claim 1 , wherein the composition additionally comprises an additive selected from the group consisting of myreth-3-myristate, glycerol monolaurate, laureth-4, ascorbic acid, sodium bisulfite, and vitamin E.
