ZINC/STRONTIUM FLUORIDE HYDROXYAPATITE.

Insufficient Data / ANTIPLAQUE

This biomimetic mineral compound combines zinc, strontium, and fluoride with hydroxyapatite. While primarily researched for oral health benefits, general hydroxyapatite has cosmetic applications as a skin conditioner or booster.

Summary

Abrasive Bulking Oral Care Skin Conditioning Sunscreen Booster Soft-Focus Agent

Science

Mechanism of Action

It forms a protective layer, promoting remineralization and reducing demineralization, particularly in hard tissues. Zinc contributes antibacterial properties, while fluoride and strontium enhance stability and remineralization potential. The specific mechanism for skin is not explicitly detailed.

Key findings

  1. 01 Strontium-doped nano-hydroxyapatite demonstrated superior enamel remineralization in incipient carious lesions.
  2. 02 A multi-component toothpaste with zinc-citrate, hydroxyapatite, potassium-citrate, and fluoride reduced S. mutans and tooth sensitivity more effectively than fluoride alone.
  3. 03 Zinc-hydroxyapatite micro-particles showed significant enamel remineralization against erosion.

Stability

Fluoride incorporation enhances stability and reduces solubility, particularly at lower pH (<3.9), making it more stable than pure hydroxyapatite.

Synergies

  • Combination of fluoride with low concentrations of zinc can form dense, homogeneous crystal layers.

Conflicts

  • High concentrations of zinc ions (Zn²⁺) have been observed to inhibit hydroxyapatite crystal formation.
