CALCIUM/MAGNESIUM HYDROXYAPATITE.

Valuable / ORAL CARE

A sophisticated biomimetic mineral complex that mirrors the natural composition of human hard tissues to deliver multifunctional benefits across skin and oral care. This electrolyte-rich mineral serves as a high-performance alternative to traditional mattifying agents by balancing sebum levels while actively supporting the epidermal barrier.

Summary

Sebum adsorbent Soft-focus agent Barrier repair booster Remineralizing agent Deodorant active

Science

Mechanism of Action

Utilizes 'Smart Adsorb' technology to physically entrap excess sebum and sweat molecules without dehydrating the skin. When applied, it scatters light to create a soft-focus blurring effect on imperfections and progressively releases calcium and magnesium ions—two essential minerals required for cellular homeostasis and the reinforcement of the skin's protective moisture barrier.

Key findings

  1. 01 Application of a 5-10% concentration demonstrated a 9.5% improvement in skin texture smoothness and a 10.3% boost in elasticity over a 28-day period.
  2. 02 A 20% suspension showed significant efficacy in gravimetric testing, providing moisture and odor suppression for up to 48 hours.
  3. 03 In vivo trials at 10% confirmed its ability to repair enamel micro-lesions and decrease dental sensitivity via surface remineralization.

While often used as a minor bulking agent or stabilizer at low concentrations (<1%), clinical benefits for skin texture and barrier repair require a minimum of 5%. Formulas claiming 'biomimetic repair' or 'mattifying' benefits that list this ingredient near the end of the INCI deck are likely dusting for marketing purposes.

Stability

Though technically insoluble, it is water-dispersible; it is most stable in neutral to slightly alkaline environments and is best utilized as a pre-dispersed paste to prevent particle clumping.

Synergies

  • Zinc Hydroxyapatite
  • Mineral pigments
  • Non-acidic humectants

Conflicts

  • Acidic environments below pH 5.0 (causes mineral dissolution)
  • Chelating agents like EDTA (sequesters active ions and destabilizes the mineral structure)
