Alcaligenes Polysaccharides

What is Alcaligenes Polysaccharides?

Alcaligenes Polysaccharides is a high-molecular-weight carbohydrate produced through bacterial fermentation using strains like Alcaligenes latus. This natural-derived ingredient appears as a clear, viscous solution in formulations. Commonly found in moisturizers, serums, and lotions, it works by creating a flexible, hydrating film on the skin that locks in moisture while permitting normal skin respiration. Its structure enables strong water-binding capacity, enhancing surface hydration without stickiness. In product development, it thickens formulas, prevents ingredient separation in emulsions, and refines sensory qualities for better spreadability. By interacting with the skin's outer layer, it supports suppleness and evenness, making it suitable for daily skincare routines focused on comfort and consistency.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Emulsion stabilizer
Improves emulsion robustness by preventing droplet coalescence and phase separation, often by thickening, structuring, or strengthening the interfacial layer.
Humectant
Attracts and holds water in the stratum corneum, boosting hydration and plumpness; commonly used in moisturizers, cleansers, and hair conditioners.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.

Benefits

Boosts skin hydration by attracting and retaining moisture on the surface.

Enhances product stability and texture for smoother application.

Softens skin feel by smoothing minor surface unevenness.
