Ectoine Powder for Cosmetic Formulation
Ectoine—listed by its INCI name Ectoin—is a water-soluble cosmetic active used in hydrating, barrier-support and sensitive-skin formulations.
It belongs to a group of protective molecules known as extremolytes, which are naturally produced by microorganisms that survive in challenging environments. In skincare formulations, Ectoine is valued for helping the skin retain moisture, supporting barrier function and improving resilience to environmental stress.
JustGlow supplies cosmetic-grade Ectoine powder in small quantities for independent cosmetic formulators, skincare businesses and product-development projects.

How to Use Ectoine
Ectoine is soluble in water and can be incorporated into water-based skincare formulations.
For simple formulations, pre-dissolve the powder in water before adding it to the main batch. It may be added during the water phase or during cool-down, depending on the manufacturing process and the supplier’s technical guidance.
When heat-stability information is not available for the exact material, adding it below 40°C is a cautious formulation approach.
Always check that the Ectoine has dissolved completely before filling the finished product.
