Red algae and hydrolysis

Red algae are among the oldest plant groups on Earth. They grow in oceans worldwide, often deeper than green and brown algae, and are known as a source of carrageenan and agar. They are rich in sugars, minerals and proteins, and hydrolysis breaks these larger molecules into smaller fragments that work well in water-based cosmetics.

A marine base

The extract is made in sea water, which adds marine minerals and a strong ocean story. Marine cosmetics appeal to consumers who link the sea with freshness and vitality.

Oxygen and city concepts

Oxygen-themed products promise a fresh, rested look for dull and tired skin, especially for city dwellers. Rodacea fits this story with its marine origin and antioxidant positioning. Day creams, restoring night creams, light cooling eye gels and marine mask essences are the natural formats.

Processing and partners

Stir Rodacea into the water phase below 40 °C until uniform. It pairs with ectoin for comfort and with the multimineral complex for a fuller marine story. 3M3 Whiteris is another red algae active, focused on tone. Similar ingredients are listed in our hydrolysates section.
