Claims22
1-25. (canceled)
A stable petrolatum-based composition comprising:
- greater than about 80% by weight petrolatum;
- a polar solvent;
- and
- a cationic biocide, wherein the cationic biocide is selected from the group consisting of benzalkonium chloride, cetrimide, chlorhexidine, polihexanide biguanide, polyaminopropyl biguanide, and any combination thereof;
- wherein the composition contains no emulsifier.
2 more elements
A stable petrolatum-based composition consisting essentially of:
- greater than about 80% by weight petrolatum;
- a polar solvent;
- and
- a cationic biocide, wherein the cationic biocide is selected from the group consisting of benzalkonium chloride, cetrimide, chlorhexidine, polihexanide biguanide, polyaminopropyl biguanide, and any combination thereof.
1 more element
A process for preparing a petrolatum-based composition comprising petrolatum and a cationic biocide the process comprising:
- a) dissolving the cationic biocide in a polar solvent to give a antimicrobial ingredient solution;
- b) heating the petrolatum to a temperature sufficient to cause the petrolatum to melt to give a melted petrolatum and heating the antimicrobial ingredient solution to a temperature higher than the temperature of the melted petrolatum to give a heated antimicrobial ingredient solution;
- c) mixing the melted petrolatum and the heated antimicrobial ingredient solution to give a melted mixture;
- and
- d) cooling the melted mixture to give the petrolatum-based composition, wherein the composition comprises greater than 80% by weight petrolatum and contains no emulsifier.
