Abstract
Provided herein are microalgal skin care compositions and methods of improving the health and appearance of skin. Also provided are methods of using polysaccharides for applications such as topical personal care products, cosmetics, and wrinkle reduction compositions. The invention also provides novel decolorized microalgal compositions useful for improving the health and appearance of skin. The invention also includes insoluble polysaccharide particles for application to human skin.
Claims20
A gel-forming composition for use in a gel, lotion, cream or ointment, the composition comprising exopolysaccharide particles produced by the process of:
- extracting, from a microalgal cell culture medium, a microalgal exopolysaccharide secreted by the microalgal cells into the culture medium, wherein the microalgal cells are of the genus Parachlorella;
- drying the extracted microalgal exopolysaccharide to form a film;
- heating the extracted microalgal exopolysaccharide at a temperature in a range from 135° C. to 152° C.;
- and
- generating particles having an average size of between 0.1 to 400 microns,
- wherein the particles comprise the heated exopolysaccharide and increase in volume on contact with water by at least 200% so as to form a gel.
A gel-forming composition for use in a gel, lotion, cream or ointment, the composition comprising exopolysaccharide particles produced by the process of:
- extracting from a culture medium a microalgal exopolysaccharide secreted by a culture of microalgal cells into the culture medium, wherein the microalgal cells are of the genus Parachlorella;
- drying the extracted exopolysaccharide to form a film;
- heating the extracted exopolysaccharide at a temperature from 148° C. to 160° C.;
- and
- generating particles having an average size of between 0.1 to 400 microns,
- wherein the particles comprise the heated exopolysaccharide and increase in volume on contact with water by at least 200% so as to form a gel.
