About WATANABEA RENIFORMIS OIL
A sustainable microalgal oil from cultured algae, offering a novel botanical alternative to conventional fixed oils with a clean safety profile suited to cosmetic formulations.
Detailed Analysis
Watanabea reniformis oil is a fixed oil produced by the trebouxiophyte green alga Watanabea reniformis grown under controlled culture conditions, making it a sustainable and traceable alternative to wild-harvested botanical oils. The alga is a single-celled freshwater species, and the oil's fatty acid profile includes typical microalgal lipids such as linoleic acid, oleic acid, and carotenoids. As a cultured organism, it is free from environmental contaminants and heavy metals that can accumulate in wild-harvested botanicals. EU cosmetic regulation EC 1223/2009 has no specific restriction for this alga-derived oil, and the controlled production process provides a safety profile consistent with other well-characterized microalgal oils used in cosmetics.
