Abstract
A cleansing bar composition comprising at least one cleanser chosen from soap and surfactant; phenoxyethanol; and one or more hydrophobic stabilizing agents, wherein the composition is a solid cleansing bar. Also methods of enhancing the deposition of phenoxyethanol by a cleansing bar comprising the step of pre-mixing phenoxyethanol with one or more hydrophobic deposition aids during manufacturing of the cleansing bar.
Claims16
A cleansing bar composition comprising:
- a) at least one cleanser chosen from soap and surfactant;
- b) phenoxyethanol;
- and
- c) one or more hydrophobic deposition aids,
- wherein the phenoxyethanol is coated by the hydrophobic deposition aid by premixing the phenoxyethanol with the hydrophobic deposition aid, wherein the composition is a solid cleansing bar,
- wherein the hydrophobic deposition aid comprises at least one material chosen from a material having a water solubility less than 1% by weight, petrolatum, white petrolatum, snow white petrolatum, a vegetable oil, palm oil, palm kernel oil, coconut oil, a seed oil, jojoba oil, jojoba wax, a fat, triglyceride, tallow, shea butter, a glycerol ester of a C8-C22 fatty acid;
- a glycerol ester of lauric, palmitic, stearic, oleic, linoleic or myristic acid;
- a C8-C22 fatty alcohol, lauryl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, cetyl alcohol or myristyl alcohol, a C8-22 fatty acid, lauric acid, palmitic acid, stearic acid, oleic acid, linoleic acid or myristic acid, a silicone, or a mineral oil, and
- wherein the composition exhibits at least 11% Deposition Improvement (D.I.), wherein said D.I. is calculated as (PE=phenoxyethanol, and control=water):

A method of increasing phenoxyethanol deposition by a cleansing bar comprising:
- a) combining phenoxyethanol in a hydrophobic deposition aid to form a mixture, and coating the phenoxyethanol with the hydrophobic deposition aid by pre-mixing the phenoxyethanol with the hydrophobic deposition aid;
- b) adding the mixture to at least one cleanser chosen from soap and surfactant;
- and
- c) forming a cleansing bar;
- wherein the hydrophobic deposition aid comprises at least one material chosen from a material having a water solubility less than 1% by weight, petrolatum, white petrolatum, snow white petrolatum, a vegetable oil, palm oil, palm kernel oil, coconut oil, a seed oil, jojoba oil, jojoba wax, a fat, triglyceride, tallow, shea butter, a glycerol ester of a C8-C22 fatty acid;
- a glycerol ester of lauric, palmitic, stearic, oleic, linoleic or myristic acid;
- a C8-C22 fatty alcohol, lauryl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, cetyl alcohol or myristyl alcohol, a C8-22 fatty acid, lauric acid, palmitic acid, stearic acid, oleic acid, linoleic acid or myristic acid a silicone or a mineral oil.
