micno powder for cosmetic micno csa-n


Hydrophobic surfaces have been attracted much interest in the last 15 years for cosmetic applications to increase the water-resistant property of personal care products. Especially for the sunscreens, in summer the end-users started to demand sunscreens which is more water-repellant while they are swimming in the sea or pool. In this way, they will be able to use their sunscreens longer.

In the scope of scientific view, coating the surfaces of mineral UV-filters resulted in more photostable products. Entekno has developed a novel coating technology to cover the surface of MicNo ZnO Powder with stearic acid. We are so happy to introduce our new product to you. This new product is MicNo CSA-N.

MicNo CSA-N is a novel particle technology that is stearic acid coated form of MicNo®-ZnO. Our natural novel surface modification process provides superior properties including improved steric effect by eliminating migration possibility of conventional Zinc Oxides from oil phase to water phase in the cosmetic formulations, high surface stability against the UV-rays, advanced surface morphology, high water resistance performance in cosmetic applications etc.
