What Is Alcaligenes Polysaccharides?
Alcaligenes polysaccharides are naturally occurring carbohydrate polymers derived from Alcaligenes bacteria. In skincare, they function as multitasking ingredients that condition the skin surface, improve product texture, and help stabilise emulsions.
These polysaccharides work by forming a light film on the skin and enhancing the consistency of formulations. They're used sparingly in cosmetics, appearing in approximately 0.1% of skincare products, typically at low concentrations.
How It Works
Alcaligenes polysaccharides function primarily as film-formers and humectants. When applied to skin, they form a light protective layer that helps reduce transepidermal water loss whilst remaining breathable.
Within formulations, these polymers increase viscosity and stabilise the emulsion structure, preventing ingredients from separating. This dual role—both skincare benefit and formulation support—makes them efficient multifunctional ingredients.
Clinical Evidence & References
Research on polysaccharides from Alcaligenes bacteria suggests potential immunomodulatory properties through interaction with skin immune receptors, though most evidence comes from laboratory and animal studies rather than human skincare trials.
Specific clinical data on cosmetic efficacy in human subjects remains limited. The ingredient appears to be well-tolerated in formulations, but larger human studies would strengthen confidence in its skincare claims.
How to Use
Alcaligenes polysaccharides are typically incorporated into serums, moisturisers, and emulsions by manufacturers rather than used as standalone products. When present in skincare, they're generally used daily as part of your regular routine. Look for them in the ingredient list if you're seeking improved product texture or formulation stability.
