HP1 Z-Cote Zinc Oxide
UV Protection with this sunscreen ingredient made for your cosmetics and lotions. This is a hydrophobic (dispersible in oil; a.k.a fat loving), coated with Dimethicone zinc oxide which is compatible with all oil phases. It is recommended for a loose powder formulation because it will tend to not absorb the moisture in the air over time which would result in a clumpy powder.
Recommended to easily disperse into a Water in Oil emulsion (typical of a commercial/high performance lotion which has more oil - including silicone oils.
All Z-Cotes contain aggregates of nano-particles with primary particle size of less than 200 nm. As a result, these Z-Cotes are transparent, non-staining, non-greasy when applied to the skin by using them alone or mixing them in cosmetic formulas yet still offer both broad-spectrum UVA and UVB protection.
We recommend Z-Cote for sun protection. However, be reminded that if you make a formal claim as to SPF protection of a product which you sell, you are considered by the FDA to be selling an over-the-counter drug. The FDA would require you to conduct independent testing of your product to confirm the SPF rating which you are marketing.
