PDRN vs exosomes: choosing an active for cosmetic formulas

PDRN vs exosomes is most useful when discussed as a formulation problem rather than a marketing trend. In 2026, search intent increasingly centers on compatibility, use levels, pH, processing order and ingredient selection for a specific product format. This guide therefore combines formulation logic, a practical prototype and internal navigation to relevant Mylo Opt raw materials.

Zinc Oxide 50 g

Why Zinc Oxide Remains the Go-To Mineral Shield Against UV Rays

Zinc oxide is a fine white mineral powder valued worldwide primarily for its role as a physical sunscreen agent, reflecting and scattering ultraviolet radiation right on the skin surface rather than absorbing it chemically. This is why the product belongs to the UV and SPF Filters for Cosmetics category, which brings together ingredients used to build broad spectrum sun protection formulas. Beyond sunscreens, zinc oxide is a staple in diaper rash creams, soothing balms for sensitive and irritated skin, and mattifying skincare, and it also finds steady demand in pharmaceutical ointments and, on the industrial side, in rubber vulcanization and ceramic glazes. Still, the largest global search and purchase volume today comes from the cosmetic industry, where formulators rely on its ability to form a protective barrier without penetrating the skin.

In sunscreen emulsions, zinc oxide is typically dosed between 10 and 25 grams per 100 grams of formula, depending on the targeted SPF level. The powder is dispersed into the oil phase during the heating stage, at roughly 70-75 degrees, and mixed thoroughly to avoid clumping and achieve an even distribution of particles. Non-micronized powder tends to produce a thicker, more opaque finish, which is why many formulators prefer a ready-dispersed alternative such as oil-dispersible Zinc Oxide, which blends more easily into the cool phase and leaves a lighter feel on the skin.

To broaden UV coverage, zinc oxide is frequently paired with organic filters: combining it with Uvinul Easy boosts protection in the UVB range while lowering the overall mineral load in the formula, keeping the emulsion feeling lighter on application. To counter the whitening cast typical of mineral filters and improve the matte finish, formulators often add silica-based fillers such as Silica Dimethyl Silylate, which absorbs excess sebum and gives the skin a more natural, non-cakey appearance.

The 50 gram pack is well suited for home cosmetic making, trial batches and small formulation tests, allowing formulators to check dosage and texture before scaling up production. Store the powder in a tightly sealed container, in a dry place away from moisture and direct sunlight - zinc oxide is chemically stable over long periods, but it can clump if exposed to humid conditions before use.

Mineral Sunscreen Stick

Zinc oxide 14 g

Beeswax 12 g

Coconut oil 18 g

Shea butter 15 g

Vitamin E 1 g

Melt the beeswax, coconut oil and shea butter together in a double boiler until fully liquid. Gradually add the zinc oxide in small portions, stirring continuously until the powder is fully incorporated and no lumps remain. Remove from heat, let the mixture cool slightly to about 45 degrees, stir in the vitamin E, then pour into stick containers or tins. Allow the stick to set fully at room temperature before capping and use.
