22 Zinc Oxide is Safe & Transparent UVA filter Benefits (1) UVA protection (2) Minimized skin irritation (3) Transparent formula Zinc oxide is a physical block that is not absorbed, so it does not cause any allergic reactions. This is especially important to look for if you have sensitive skin or are using sunscreens on a daily basis. ZnO Only Very Transparent TiO2 Not Transparent And unlike many chemical sunscreen agents, zinc oxide is never irritating. In fact, it is recognized by the Food and Drug Administration as a Category I skin protectant, meaning that it is safe for compromised or environmentally challenged skin. Zinc oxide is the closest thing to a total "broad-spectrum" sunblock on the market today. It uniformly covers from 290 to 380 nm, thus protecting against UVB and most of the UVA spectrum. No other sunscreen ingredient provides broader protection. Zinc oxide has over a 300-year history of safety, with no known adverse reactions (which is why it is often used to treat babies). Now, in its micro-fine form, it is ideal for use in sunscreens and daily moisturizers.

23 FAQ about Zinc Oxide Questions Q1. SPF is the half of TiO 2 A. Yes it is. But ZnO has great 15.0 synergy with OMC. Thus the 10.0 SPF of 3% ZnO and 5% OMC would be comparable to the 5.0 SPF of 3% TiO 2 and 5% OMC. ZnO with OMC SPF 6.5 SPF 13.6 Boost TiO 2 with OMC SPF Although ZnO would have lower SPF than TiO 2 by themselves, ZnO shows greater SPF boost when used together with OMC compared to TiO 2 with OMC. Zinc Oxide has higher SPF boost when used together with OMC as compared to TiO 2 OMC 5% SUNZNO -NAS 3% OMC NAS OMC TiO 2 3% 5% + OMC TiO 2 3% 5% 5% + 3% Q2. Not stable in O/W formula A. Generally ZnO is considered not stable in O/W formulation. However, if zinc oxide is well surface treated, almost there is no problem. A common caution in formulating a ZnO-containing product is to avoid or to minimize the use of anionic emulsifier or thickener such as carbomers At ph values < 6, the solubility of zinc oxide increase and migration from the oil phase to water phase observed For this reason, ZnO is usually incorporated into the oil phase of the formulation. Moreover these problems can be minimized or eliminated by various means. Use of an optimized predispersion maintains the ZnO in a finely dispersed form in the oil phase. In W/O emulsions, such dispersion techniques are sufficient to eliminate migration and efficacy of ZnO. ZnO can also be coated with hydrophobic materials in order to reduce migration Q3. Price too expensive as compared to TiO 2 As SUNJIN chemical applies one step coating process for surface treated Zinc Oxide, zinc oxides from SUNJIN are very price competitive. SUNJIN tries to match the price level of Zinc Oxide comparable to the price of microfine TiO 2
