Skin-brightening compositions and methods

A skin-brightening cosmetic composition comprising:

• a. from about 1 to about 4 wt % of hydrogen peroxide;
• b. from about 1 to about 5 wt % of at least one alkaline booster selected from the group consisting of guanidine carbonate, arginine, monoethanolamine, triethanolamine, potassium hydroxide, sodium bicarbonate and combinations thereof;
• and
• c. from about 30 to about 60 wt % of at least one fatty compound selected from the group consisting of mineral oil, hemisqualane and combinations thereof,
• wherein the skin-brightening cosmetic composition is ammonia-free and persulfate-free.

A method for brightening skin, comprising applying to the skin a composition comprising

• a. hydrogen peroxide;
• b. at least one alkaline booster;
• and
• c. at least one fatty compound present from about at least 30% by weight, based upon the total weight of the composition,
• wherein the skin-brightening cosmetic composition is ammonia-free and persulfate-free, and wherein the composition is provided as a multi-part system, the parts separately containing two or more sub-compositions each of which comprises one or a combination of the hydrogen peroxide, alkaline booster, and fatty compound components, which sub-combinations are combinable at the time of use.

An article of manufacture for providing a skin brightening composition, the article comprising:

• at least first and second separately contained sub compositions that are mixable prior to application to keratinous tissue to form a brightening composition, the brightening composition comprising hydrogen peroxide;
• at least one alkaline booster;
• and at least one fatty compound present from about at least 45% by weight, based upon the total weight of the composition, wherein the skin-brightening cosmetic composition is ammonia-free and persulfate-free, comprising:
• a. a first sub composition comprising the hydrogen peroxide and any additional optional oxidizing agent, and
• b. a second sub composition comprising the alkaline booster,
• Wherein either one or both of the first and second sub compositions comprises one or more of the fatty compound and any one or more of solvents, surfactants, polymers, actives and other components.
