This finely milled zinc oxide provides formulators and DIY skincare makers with a consistent, high-purity mineral ingredient. Because it is non-nano and uncoated, the powder maintains its natural particle profile and surface chemistry, making it suitable for use in a variety of topical cosmetic products where mineral protection, opacity, or texture modification is desired. The 8-ounce size is convenient for small-batch production, prototypes, and home projects.
Start by dispersing the powder thoroughly into the chosen oil, emollient, or cream base to avoid clumping and ensure even coverage. For mineral sunscreen formulations, manufacturers recommend targeting between 15% and 25% zinc oxide by weight for adequate mineral coverage; smaller concentrations of around 5% are typical for other cosmetic uses. Always weigh ingredients and mix with a high-shear tool or mortar and pestle for best incorporation.
Non-nano indicates the powder’s primary particles are above the nanoscale and are not engineered into nanoparticle sizes; uncoated means the powder has no additional surface treatments. These attributes preserve the original mineral surface and are commonly chosen for traditional mineral formulations. Safety in topical use depends on formulation, concentration, and regulatory guidance in your region, so follow cosmetic safety best practices.
To reduce visible whitening and improve spreadability, pre-disperse zinc oxide into an oil or use a dispersant compatible with your base. Heat phases gently when incorporating into emulsions, and perform stability checks (freeze/thaw, centrifuge) on sample batches. Small particle aggregates respond well to sieving or brief micromilling; avoid airborne dust when handling.
Keep the zinc oxide powder in a cool, dry place away from direct sunlight and moisture to preserve its physical quality. Store in a tightly sealed container and label with opened date for inventory control. When measuring and mixing, use gloves, a dust mask or respirator, and eye protection to minimize inhalation and contact.
Who is this for? Formulators, indie beauty brands, hobbyists and small-batch producers seeking a reliable, cosmetic-grade mineral base will find this Sturelehub zinc oxide powder useful. It suits those making mineral sunscreens, tinted creams, deodorants, powders, and other topical products who want a non-nano, uncoated ingredient to control opacity, texture, and mineral performance in their recipes. It is not a finished product; proper formulation practice and testing are recommended prior to consumer use.
zinc oxide
Q: Can I use this zinc oxide powder directly on skin?
A: This is an ingredient for formulations; mix into a cream or oil base rather than applying loose powder directly.
Q: What concentration works for mineral sunscreen?
A: For mineral sunscreens, aim for 15%–25% zinc oxide by weight; test and adjust for desired opacity and feel.
