marine biopolymer providing ultimate water delivery and textural sensation
MariMoist® is a whole-plant extract of the aquatic plant Chondrus crispus (red seaweed; Rhodophyceae) in combination with bio-derived sodium hyaluronate.
High-quality, natural biomass is converted through a sustainable, renewable process to yield a water-soluble, viscous, hydrocolloid-flowing gel with the highest standards of consistency, quality, and purity.
MariMoist® is a moisturization ingredient that delivers high volumes of water to the skin for immediate and sustained hydration to soften dry skin. In addition to water delivery, MariMoist® imparts unique, pleasing sensorial effects on the skin and hair. MariMoist® elevates the aesthetic and tactile properties of finished products, helping to build ‘body’ and impart a rich, luxurious feel to finished formulas, without feeling tacky or sticky.
