UV Cut ZnO-61
UV Cut ZnO-61 is a 60% dispersion of zinc oxide in cyclomethicone. UV Cut ZnO-61 offers very efficient UVA protection with transparent appearance due to its finely dispersed particle size. In addition, UV Cut ZnO-61 features a stable dispersion without sediment and provides a non-greasy and smooth skin feel, and strong water-repellency. Because of its skin compatibility and non-toxic property, UV Cut ZnO-61 is recommended for daily care products. The combination of UV Cut ZnO-61 with UV Cut TiO2 allows formulating physical suncare products with a broad spectrum UV protection.
