Composite ACT-50 is a white powder with a characteristic odor. This product contains dispersed attenuation grade TiO2 entrapped within a micron size Acrylates Copolymer matrix. Kobo’s process reduces the agglomeration of TiO2 aggregates which offers high SPF efficacy, low whitening effect and better tactile properties. In lotions, Composite ACT-50 can provide similar SPF values and a higher critical wavelength than non-entrapped TiO2 of a similar particle size. It has also been shown to boost SPF in formulas containing organic sunscreens. In addition, it can provide SPF and add to good skin feel in pressed powders.

复合ACT-50是一种具有特征气味的白色粉末。该产品含有分散的衰减级TiO2，包埋在微米尺寸的丙烯酸酯共聚物基质中。 Kobo的工艺减少了TiO2聚集体的聚集，其提供高SPF效力，低增白效果和更好的触觉性质。在乳液中，复合物ACT-50可以提供与未包埋的相似粒度的TiO2相似的SPF值和更高的临界波长。它也被证明可以提高配方中含SPF的有机防晒霜。另外，它可以提供SPF并增加压制粉末的良好肤感。
