Solaveil CZ-300: incorporating a zinc oxide dispersion into SPF formulations

A dispersion rather than dry ZnO

Solaveil CZ-300 100 g is listed as a thick white-to-cream material with INCI Zinc Oxide and Triethoxycaprylylsilane. It is water-insoluble and dispersible in oils and emulsion bases, so its processing differs from raw zinc oxide powder.

Why pre-dispersion helps

A prepared mineral dispersion reduces the separate powder-wetting step, but uniform distribution, rheology and emulsion stability still need to be controlled.

Filter percentage is not an SPF claim

The percentage of UV-filter raw material does not by itself establish a finished-product SPF or UVA claim. Protection depends on the complete formula and film and must be confirmed by appropriate finished-product testing.

Formulation checks

·        uniformity without streaks or agglomerates

·        viscosity after full cooling

·        storage stability

·        pigment compatibility in BB and CC products

·        film uniformity

·        package compatibility

Regulatory check

UV-filter rules differ by market. Confirm that the exact filter system is permitted for the intended market and follow applicable testing and labeling requirements.

Conclusion

Solaveil CZ-300 can simplify zinc oxide handling, but sunscreen development still depends on controlled dispersion, stable film formation, regulatory review and testing of the finished product.
