Sodium Alginate 50 g

Sodium Alginate high molecular marine polysaccharide for gel and modeling systems

Sodium Alginate is a naturally derived anionic polysaccharide extracted from brown seaweed. It appears as a fine white to light cream powder with neutral odor. Fully soluble in water, it forms viscous solutions and elastic gel systems upon hydration and crosslinking with calcium salts. Insoluble in oils, it must be gradually dispersed into the aqueous phase to ensure uniform hydration. The dry powder format ensures storage stability and predictable rheological behavior suitable for industrial manufacturing.

Properties and skin performance

Forms smooth homogeneous gel textures with controlled viscosity. In modeling mask systems it creates a dense elastic network that evenly distributes active ingredients across the surface. The gel maintains integrity during removal, contributing to a visually smoother skin appearance. Provides balanced glide and non tacky sensory profile when properly formulated.

Industry applications

Sodium Alginate is widely used in peel off and modeling masks, hydrogel systems, SPA treatments and professional cosmetic applications. It is also applied in pharmaceutical and food industries as a structuring agent. Suitable for private label and contract manufacturing due to scalable gel formation and reproducible viscosity under controlled hydration processes.

Formula example

Sodium Alginate 50 g
Purified water 750 ml
Glycerin 70 g
Chamomile extract liquid 40 g
Calcium sulfate 30 g
Sodium lactate 15 g

Sodium Alginate is gradually dispersed into purified water under high shear mixing until fully hydrated and free of lumps forming a viscous uniform solution. Glycerin is incorporated to enhance texture and mixing continues until homogeneous. Calcium sulfate is added to initiate crosslinking and gel network formation. Chamomile extract and sodium lactate are then introduced with continuous mixing. pH is adjusted to a balanced range suitable for polysaccharide systems. The final result is a plastic gel mass designed for elastic modeling mask applications.

Sodium Alginate is positioned for B2B manufacturers of professional cosmetic and hydrogel systems. It ensures structural stability, controlled viscosity and reproducible gel performance in scalable industrial and contract production environments.
