Abstract
The invention provides cosmetic compositions comprising microalgal biomass, whole microalgal cells, and/or microalgal oil in combination with one or more other cosmetic ingredients, and methods of making such compositions. In preferred embodiments, the microalgal components of the cosmetic compositions are derived from microalgal cultures grown heterotrophically and which comprise at least 10% oil by dry weight.
Claims20
A non-green topical cosmetic composition comprising microalgal biomass of heterotrophically cultivated Chlorella protothecoides wherein the biomass is not green in color and comprises less than 5% DHA, and at least one other cosmetic ingredient, wherein the microalgal biomass comprises at least 10% microalgal oil by dry weight.
A non-green topical cosmetic composition comprising at least 1% w/w microalgal oil and at least one other cosmetic ingredient, wherein the microalgal oil is isolated from Chlorella protothecoides that is cultured heterotrophically, is not green in color, and comprises less than 5% DHA.
A method of making a non-green topical cosmetic composition comprising combining microalgal biomass with at least one other cosmetic ingredient to form a cosmetic composition, wherein the microalgal biomass comprises at least 10% microalgal oil by dry weight, wherein the microalgal biomass comprises Chlorella protothecoides that is cultured heterotrophically, is not green in color, and has less than 5% DHA.
A method of making a non-green topical cosmetic composition, the method comprising combining non-green microalgal oil isolated from microalgal biomass containing at least 10% microalgal oil by dry weight with one or more other cosmetic ingredients to form a cosmetic composition, wherein the microalgal biomass comprises Chlorella protothecoides that is cultured heterotrophically, is not green in color, and has less than 5% DHA.
A method of using a microalgal biomass topical composition to soften and impart pliability to skin, the method comprising:
- applying to human skin a composition comprising predominantly intact microalgal cells containing at least 10% microalgal oil by dry weight, wherein the cells are of the species Chlorella protothecoides that are heterotrophically cultured and are not green in color, and comprise less than 5% DHA.
A non-green topical cosmetic composition comprising lysed, heterotrophically cultivated, spray-dried Chlorella protothecoides cells of at least 30% oil by dry weight and at least one other ingredient, wherein the cells are not green in color, and the oil has less than 5% DHA.
A method comprising applying to the skin, a non-green topical composition comprising non-green oil extracted from heterotrophically cultivated cells of Chlorella protothecoides that are not green in color and comprise less than 5% DHA.
