Why dispersion? PROS 1. Better transparency 2. Higher SPF 3. Better batch consistency of color or transparency or sun protection 4. Improved skin feel and texture 5. Easy to use. No dusty work Elimination of powder handling No need of dispersing hard to disperse, TiO2 New Californian Law about Dust 1. Expensive CONS
Why dispersion? Well Dispersed Transparent Higher SPF W/O Sun Lotion 2 SPF boost per % of TiO2 @ 5% 3 SPF boost per % of TiO2 @ 8% TiO2 Dispersion O/W Sun Lotion 3 SPF boost per % of TiO2 @ 5% 3 SPF boost per % of TiO2 @ 8% TiO2 powder Poorly Dispersed White SPF not fully shown W/O Sun Lotion 1.5 SPF boost per % of TiO2 @ 5% 2 SPF boost per % of TiO2 @ 8% O/W Sun Lotion 2 SPF boost per % of TiO2 @ 5% 2 SPF boost per % of TiO2 @ 8%

SPF boost with OMC 30.0 25.0 20.0 15.0 8.5 22.5 Good synergy with OMC SPF boost = 7.5 10.0 6.5 50 5.0 OMC, 5% SUNCLEAR- T40C 7% T40C, 7% OMC 5% Net TiO2 of 7% T40C = 40% * 7% = 2.8% Unit SPF of net TiO2 = SPF 8.5/(40%*7%) = 3 SPF/g Excellent SPF efficiency: 3 SPF/g
Chemical Filter Free 30.0 25.0 20.0 Chemical filter free 20.8 24.9 Tin40 is low SPF by itself But when used together with TiO2 & ZnO, 15.0 10.0 5.0 0.8 4.2 8.5 this combination has very good complementary SPF boost Moreover, Tin40 has spherical silica bead so provides silky spread Tin40 4% NAS 3% T40C 7% T40C 7% NAS 3% Tin40 2% T40C 7% NAS 3% Tin40 4% So TiO2, ZnO and Tin40 combination is very good for Chemical filter free formulation For more detail, please refer to SJ_3.0_UVfilters_SPF synergy file
