UV filter ZINC OXIDE 1 kg

Why Zinc Oxide Remains a Core Physical Sunscreen Ingredient Worldwide

UV filter ZINC OXIDE in the 1 kg pack belongs to the UV and SPF Filters for Cosmetics section, which brings together raw materials used to build sun protection formulas of varying strength. This is a mineral, physical filter: its particles reflect and scatter ultraviolet radiation on the surface of the skin rather than penetrating deep into the epidermis, and it does not undergo photochemical breakdown over time. This mechanism explains why zinc oxide remains one of the most requested raw materials in global sunscreen manufacturing, baby care lines, and products aimed at sensitive or reactive skin.

The primary application of zinc oxide as a UV filter includes sunscreen creams, lotions, sprays, sticks, mineral BB and CC creams, tinted foundations with declared SPF, and after-sun repair emulsions. Because it stays stable under sunlight and does not degrade with prolonged exposure, it is widely recognized as suitable for children's products and formulations intended for delicate skin. Beyond cosmetics, zinc oxide is heavily used in several other industries worldwide: the rubber industry relies on it as a vulcanization activator, the ceramics and glass industries use it as a glaze component, paint and coating manufacturers add it to improve resistance to UV and moisture, and pharmaceutical production uses it in external powders and protective ointments. Still, within the cosmetic raw material market, its role as a physical UV filter is the main driver of demand.

When formulating with zinc oxide, proper dispersion in the oil phase is essential — it should be introduced at 70-85 degrees Celsius under continuous mixing, ideally with a dispersing agent or lecithin, to avoid the white cast on skin and ensure an even particle distribution. Typical usage levels in a finished formula range from 10 to 25 percent depending on the targeted protection factor. To achieve broader UVA and UVB coverage, zinc oxide is often paired with organic filters such as Butyl Methoxydibenzoylmethane, which effectively covers the long-wave UVA range, and photostable Tinosorb M, known for its resistance to sunlight degradation. Another strong partner is the encapsulated Protection lens, which reduces skin irritation by capsulating active UV molecules.

Zinc oxide pairs well with titanium dioxide for a balanced protection profile, with silicones for improved spreadability and skin feel, and with plant oils and emulsifiers to create lightweight, non-greasy emulsions. Store the raw material in a dry, cool place inside a tightly sealed container, away from moisture and direct sunlight, to keep particle stability throughout the declared shelf life. The 1 kg pack suits both small-batch studio production and regular, steady supply for compact manufacturing operations that need consistent, repeatable results without committing to bulk industrial volumes.

Mineral Daily Face Cream with SPF

Distilled water 580 g

Zinc oxide 150 g

Titanium dioxide 20 g

Jojoba oil 65 g

Plant-based emulsifier 45 g

Glycerin 30 g

Niacinamide 6 g

Broad spectrum preservative 4 g

Heat the oil phase containing jojoba oil and the emulsifier to 75 degrees. Separately, disperse the zinc oxide and titanium dioxide in a small portion of the oil until a smooth, lump-free paste forms, then blend it into the oil phase under constant mixing. Heat the water phase with glycerin to the same temperature and slowly pour it into the oil phase while emulsifying with a mixer until a stable cream forms. Once cooled to 40 degrees, add niacinamide and preservative, mix thoroughly, and transfer the finished cream into clean containers.
