Science
Mechanism of Action
Calcium Tartrate operates by releasing calcium ions into the epidermis, which are essential for maintaining the lipid barrier and regulating cell turnover. Additionally, it acts as a pH regulator and stabilizer, neutralizing excess acidity in the formulation to ensure a consistent, skin-compatible environment throughout the product's shelf life.

Dusting Analysis
As a functional ingredient primarily used for pH adjustment and stabilization, it is rarely marketed as a primary 'active,' making it unlikely to be subject to marketing dusting.
The Formula
Formulation
Stability
Possesses a low water solubility of approximately 0.01–0.04 g/100 ml at 20°C. Stability is maintained in neutral to alkaline environments, though solubility increases as pH decreases or temperature rises.
Synergies
