Claims26
A method of treating skin or tissue, comprising applying to the surface of animal skin or tissue an effective amount of a composition capable of forming a film that ionically bonds to the skin or tissue comprising the residue of:
- a. one or more active agents;
- b. a nonionic or substantially nonionic first film forming component comprising one or more fatty esters, one or more fatty acids, and one or more fatty alcohols;
- c. one or more cationic surfactants comprising one or more fatty moieties that are soluble in the first film forming component;
- d. an adduct obtained by mixing a nitrogenous organic base with the fatty acid in the first film forming component, and
- e. a liquid carrier.
A method of treating skin or tissue comprising applying to the surface of animal skin or tissue an effective amount of a composition comprising the residue of:
- a. one or more quaternary ammonium compounds;
- b. one or more surfactants;
- c. one or more fatty esters;
- d. one or more fatty alcohols;
- and
- e. optionally one or more highly polar compounds;
- f. wherein the ratio of the sum of the moles of quaternary ammonium compounds, surfactants, and highly polar compounds to the sum of the moles of fatty esters and alcohols is from about 0.8 to about 1.2.
A method of treating skin or tissue comprising applying to the surface of animal skin or tissue an effective amount of an emulsion composition comprising the residue of a fatty phase, wherein:
- a. the fatty phase comprises fatty acids, glycerides, and optionally other fatty components, and
- b. The molar ratio of fatty acids to glycerides and other fatty components is from about 0.5 to about 3.5.
