What Is Zinc Oxide Powder?
Zinc Oxide is a multi-functional inorganic cosmetic raw material. It forms a uniform physical protective film on skin surface to reflect and scatter UVA and UVB ultraviolet rays, providing stable broad-spectrum sun-shielding effect. Besides UV protection, zinc oxide owns unique soothing, anti-irritant and sebum-modulating properties, friendly to sensitive skin and infant-care formulas.
Our cosmetic-grade Zinc Oxide features fine particle size, good dispersibility and low heavy-metal impurities, stable batch-to-batch consistency. Suitable for mineral sunscreen, soothing repair cream, baby care ointment and various color cosmetic systems. Each batch can provide full technical documents for cosmetic registration and formula R&D.
Core Advantages Of Our Zinc Oxide Powder
Broad-Spectrum Physical UV Defense
Physically reflects & scatters UVA and UVB rays, no skin-absorption risk, excellent photochemical stability, reliable long-term sun-protection performance.
Powerful Skin-Soothing & Anti-Irritation
Relieves skin redness and mild irritation, accelerates skin surface comfort recovery, ideal for sensitive skin, post-sun repair and baby-care formulations.
Sebum-Regulating & Opacifying Capacity
Helps control excess skin sebum secretion, delivers matte skin feeling; provides opacifying and covering power for foundations, BB creams and powder cosmetics.
Strict Heavy-Metal Control
Rigorous impurity testing, heavy-metal indexes comply with global cosmetic safety standards, low-irritation for facial and body-care end-products.
Excellent Formulation Compatibility
Compatible with oil-phase, water-phase and emulsion systems after high-shear dispersion, works synergistically with organic UV filters, plant extracts and brightening actives.
Reliable Quality & Full Technical Support
High purity ≥99.0%, strict batch inspection, support third-party independent lab testing. Provide COA, MSDS, TDS and practical formulation suggestions for your R&D team.
How Zinc Oxide Powder Works In Cosmetic Formulations
Zinc oxide particles are evenly dispersed inside cosmetic systems. After skin application, particles stay on skin surface to build a physical barrier. Incident UVA and UVB light are reflected and scattered, preventing ultraviolet rays from penetrating skin tissue and reducing UV-induced melanin activation and photo-aging damage. Meanwhile, zinc oxide exerts soothing effect to relieve skin inflammatory irritation and regulate surface sebum.
Note: Zinc Oxide cannot dissolve in water or oil. High-shear homogenizing dispersion is required. Formulators need to carry out dispersion test, compatibility test and finished-product safety & stability assessment. Final effect depends on particle size, dispersion quality, dosage and matched auxiliary ingredients.

Formulation Guide: Dosage, Dispersion & Critical Notes
Recommended addition range: Sunscreen products:5%-25%; Color cosmetics:1%-15%; Soothing skincare:1%-5%. Adjust dosage according to SPF target, covering requirement and local cosmetic regulatory limits.
Processing method: Zinc Oxide is insoluble powder. Add powder into oil phase or water phase under high-shear stirring / homogenizer, fully disperse to avoid particle agglomeration, then proceed emulsification process. Good dispersion directly determines SPF performance and skin-feeling experience.
Suggested synergistic ingredients: Compound with organic UV filters to boost SPF value; match with panthenol, centella asiatica extract to enhance soothing effect; add dispersant to improve system stability.
Important formulation reminders
- Insoluble powder, high-shear dispersion is mandatory, cannot dissolve only by simple stirring.
- Pay attention to dust-proof protection during material handling, avoid powder inhalation.
- Particle agglomeration will lead to gritty skin feel and decreased sun-protection efficiency.
- Avoid strong acid environment which may cause raw-material reaction.
- Raw material must store away from light, moisture. Seal tightly after opening and use quickly.
- Only for cosmetic raw-material use. Finished-product safety & stability test is mandatory before mass-production.
