Abstract
Described herein, a transparent soap bar for cleaning the skin including a soap surfactant, a synthetic surfactant, a fragrance component, an amine component, an antioxidant salt, wherein the transparent soap bar has a percent transmittance (% T) value of greater than 40% as measured using the method of Measurement of % Transmittance.
Claims15
A transparent soap bar for cleaning the skin comprising:
- about 10 wt. % to about 30 wt. % of a soap surfactant, by weight of the soap bar, wherein the soap surfactant is selected from the group consisting of alkali or alkaline earth metal, and ammonium salts of C6-C18 carboxylic acids;
- about 1.5 wt. % to about 30 wt. % of a synthetic surfactant, by weight of the soap bar, wherein the synthetic surfactant is selected from the group consisting of an anionic surfactant, a nonionic surfactant, and mixtures thereof;
- about 0.01 wt. % to about 2 wt. % of a fragrance component, by weight of the soap bar, wherein the fragrance component comprises ketone and/or aldehyde fragrance components;
- about 0.01 wt. % to about 5 wt. % of an amine component, by weight of the soap bar, wherein the amine component is selected from the group consisting of a primary amine, a secondary amine, a tertiary amine, a substituted or unsubstituted 2-pyridinol N-oxide material, an amphoteric surfactant, and mixtures thereof;
- about 0.01 wt. % to about 0.5 wt. % of an antioxidant salt, by weight of the soap bar, wherein the anti-oxidant salt is selected from the group consisting of an alkali metal metabisulfite, an alkali metal sulfite, an alkali metal bisulfite and mixtures thereof;
- and
- wherein the transparent soap bar has a percent transmittance (% T) value of greater than about 40% as measured according to the Measurement of % Transmittance method.

A method of preventing or reducing discoloration of a transparent soap bar, comprising:
- adding about 0.01 wt. % to about 0.5 wt. % of an antioxidant salt by weight of the soap bar, wherein the anti-oxidant salt is selected from the group consisting of an alkali metal metabisulfite, an alkali metal sulfite, an alkali metal bisulfite and mixtures thereof;
- to a premix comprising:
- about 10 wt. % to about 30 wt. % of a soap surfactant, by weight of the soap bar, wherein the soap surfactant is selected from the group consisting of alkali or alkaline earth metal, and ammonium salts of C6-C18 carboxylic acids;
- about 1.5 wt. % to about 30 wt. % of a synthetic surfactant, by weight of the soap bar, wherein the synthetic surfactant is selected from the group consisting of an anionic surfactant, a nonionic surfactant, and mixtures thereof;
- about 0.01 wt. % to about 2 wt. % of a fragrance component, by weight of the soap bar, wherein the fragrance component comprises ketone and/or aldehyde fragrance components;
- from about 0.01 wt. % to about 5 wt. % of an amine component, by weight of the soap bar, wherein the amine component is selected from the group consisting of a primary amine, a secondary amine, a tertiary amine, a substituted or unsubstituted 2-pyridinol N-oxide material, an amphoteric surfactant, and mixtures thereof;
- wherein the resulting transparent soap bar has a percent transmittance (% T) value of greater than about 40% according to the Measurement of % Transmittance method.
