Titanium Dioxide 15nm Liquid =15% Zinc Oxide 35nm Liquid =15% Cyclomethicone =50% Ethyl Alcohol =20% 1. Can it be used as a facial sunscreen spray? 2. Can it be used with children? About 3 years old 3. If you want to make it suitable for use on the face and children, how should the formula be adjusted?

Characteristics of the spray formula Titanium Dioxide and Zinc Oxide must be shaken before spraying. recipe example Titanium Dioxide 200nm EasyDisperse 10% Zinc Oxide 200nm EasyDisperse 10% Dimethicone (Very Light, Low-Odor) 30% Cyclomethicone 30% Ethyl Alcohol 20 % by the formula must be shaken before use to allow ผงกันแดด to disperse.

Hello Titanium Dioxide will cause white stains. No matter how much the particle size, the smaller particles have less chance of whiteness. To avoid whiteness Choose the smallest particle size Titanium Dioxide 15nm Liquid but Using the Liquid type does not mean Do not shake before spraying. However, it must be shaken before spraying. Titanium Dioxide , Zinc Oxide which is physical powder, can't dissolve in formula]
Las Euca Kill can be used with a child or not At what age?
Although there are a number of articles citing the safety of Lemon Eucalyptus Oil for children, which have been confirmed to be safe for children 3 years of age and older, there are no clinical trials citing that. น้ำมันตะไคร้หอม [in this case Euca Kill is Lemon Eucalyptus Oil through extraction process. increase concentration and cut off the smell] How safe is it for children? Members may need to seek further research on this subject. The team apologizes.
