CALCIUM POLYGLUTAMATE CROSSPOLYMER.

Valuable CAS - / EMULSION STABILISING, FILM FORMING, SKIN CONDITIONING

An advanced, structural evolution of poly-gamma-glutamic acid (PGA) engineered into a three-dimensional crosslinked biopolymer. This high-performance molecule functions as both a superior humectant and a sophisticated film-former to provide immediate structural support to the skin surface.

Film-forming Skin conditioning Emulsion stabilizing Humectant

Science

Upon application, this ingredient organizes into a breathable, 3D hydrogel lattice. Unlike linear polymers, this crosslinked network creates a flexible, supportive film that physically reinforces skin tension for a 'lifting' effect while simultaneously locking in moisture more effectively than standard PGA by preventing trans-epidermal water loss.

Key findings

  1. 01 In a 12-week clinical evaluation of a firming complex containing this technology, 94% of participants demonstrated improved skin lift and 91% showed enhanced overall firmness.
  2. 02 A 1-week clinical study observed a 21% improvement in skin firmness, while 8 weeks of use resulted in a 177% increase in hydration levels.
  3. 03 A 12-week study reported an 84% reduction in the appearance of fine lines and wrinkles.

Transparency

Not commonly dusted

This is a high-value functional polymer typically utilized in specialized lifting and firming technologies. While exact concentration thresholds for 'dusting' are not publicly established, its efficacy is usually verified through multi-ingredient complex clinicals.

Stability

Highly stable in aqueous environments; the crosslinked structure offers superior resistance to enzymatic and chemical degradation compared to linear polyglutamic acid. It also acts as an emulsion stabilizer by increasing the viscosity of the water phase.

Synergies

  • Hyaluronic Acid
  • Peptides
  • Linear Polyglutamic Acid

Conflicts

  • High concentrations of electrolytes (salts) which can destabilize the 3D hydrogel network and reduce film-forming efficacy.

Safety

Safe
Sensitization risk Low

While the specific crosspolymer has not been reviewed by the CIR, its parent component, Polyglutamic Acid, and its associated salts are widely recognized as safe for cosmetic use with no evidence of systemic toxicity.
