Product FAQ
What is Ectoin?
Ectoin (Tetrahydro‑methylpyrimidinecarboxylic acid, CAS 96702‑03‑3), a cyclic amino‑acid derivative from halophilic bacteria fermentation. Water‑soluble white crystalline powder, for skin moisturizing, soothing and cell‑protection, widely used in cosmetic and biological dressing formulations.
What is the recommended dosage of Ectoin in cosmetics?
For leave‑on products such as serums, creams and masks, the typical dosage is 0.5‑2.0%. It can be increased to 2‑3% for after‑sun and post‑procedure repairing formulas. For rinse‑off products, dosage is 0.3‑0.5%. Full safety assessment is required for formulas above 3%. Pay attention to solubility in low‑temperature formulations to prevent crystal precipitation.
What is the pH tolerance range for Ectoin formulations?
Stable pH range: 4.0‑8.0. Long‑term exposure under strong conditions of pH<4 or pH>8 will impair the stability of its cyclic molecular structure. The final pH of the formulation is recommended to be weakly acidic‑neutral to preserve raw‑material activity.
Storage conditions and shelf‑life of Ectoin raw material?
Seal powder raw material and store in cool, dry and dark place. Solid shelf‑life: 24 months. Aqueous solution shall be freshly prepared. Keep aqueous solution away from light and avoid long‑term high‑temperature storage to prevent impurity increase.
