CALCIUM ALGINATE.

Valuable CAS 9005-35-0 / FRAGRANCE, VISCOSITY CONTROLLING

A sophisticated marine-derived polysaccharide that functions as a structural biopolymer and a biological skin-repair catalyst. It is uniquely engineered to transition into a nutrient-rich, moisture-locking gel upon contact with skin surface electrolytes.

Science

Mechanism of Action

Calcium Alginate functions through a precise ion-exchange mechanism. When applied to the skin, it absorbs sodium ions from surface moisture, causing the insoluble calcium fibers to convert into a hydrophilic sodium alginate gel. This process creates a controlled-release system that delivers calcium ions (0.9 mM) directly to the epidermis, which is essential for maintaining the calcium gradient required for barrier restoration, keratinocyte differentiation, and fibroblast metabolic signaling.

Key findings

  1. 01 A randomized controlled trial demonstrated that calcium alginate facilitated a 70% complete healing rate by day 10 compared to 33% in control groups, highlighting its superior regenerative properties.
  2. 02 Research using lyophilized algae-calcium matrices confirmed the release of 0.9 mM of calcium ions into the skin, significantly boosting epidermal barrier repair and cellular differentiation.

Because calcium alginate is often used as a primary gelling agent in peel-off masks at high concentrations (up to 50%), it is rarely 'dusted' in those formats. However, in liquid serums, it may be included at sub-therapeutic levels (<0.1%) merely for viscosity or label claims without providing meaningful calcium ion release.

Stability

Inherently insoluble but forms stable suspensions or gels. Stability is compromised by extreme pH shifts which can precipitate alginic acid.
