We offer two kinds of Z-Cotes:
- hydrophilic (dispersible in water)
- inorganic ingredient that is ideal for hypo-allergenic formulations
- does not cause allergic reaction
- Recommended to easily disperse into an Oil in Water emulsions (typical of a "natural/homemade" lotion)
- hydrophobic (dispersible in oil; a.k.a fat loving)
- coated with Dimethicone
- compatible with all oil phases
- Recommeded 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 are microfine zinc oxides with a particle size of less than 0.2 microns (200 nm). As a result, these Z-Cotesare transparent,non-staining, non-greasywhen 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.
