Processing Methods & Reference Formulations
A. Cosmetic sunscreen cream
Use antioxidants to enhance photostability and prevent oxidation in zinc oxide-based sunscreens. Avoid strong acids or chelators to maintain zinc oxide integrity and ensure long-term product stability.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Water (Aqua) | 50-60% |
| Homosalate | 4.25% |
| Octisalate | 4.75% |
| Zinc Oxide | 6.75% |
| Dimethicone | 10% |
| Glycerin | 5% |
| Titanium Dioxide | 3% |
| Cetearyl Alcohol | 2% |
| Phenoxyethanol | 0.8% |
| Carbomer | 0.5% |
| Triethanolamine | 0.3% |
B. Paints
Add zinc oxide as an anti-corrosive pigment or mildew-resistant agent, dispersing it thoroughly using high-speed mixing. Maintain neutral to slightly alkaline pH and use dispersants to prevent agglomeration and ensure even distribution.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Binder (Resin) | 20-40% |
| Fillers/Extenders | 5-20% |
| Additives | 1-5% |
| Zinc Oxide | 10-40% |
C. Makeup foundation cream
When adding Zinc Oxide to foundation cream, disperse it thoroughly in the oil phase using a high-shear mixer to prevent clumping and ensure even coverage. Pre-coating with silicone or dispersing agents can improve skin feel and stability. Mix under controlled temperature to maintain emulsion stability and avoid settling.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Nicotinamide | 0.05% |
| Avobenzone | 0.22% |
| Zinc oxide | 0.13% |
| Titanium dioxide | 0.10% |
| Polyglyceryl-2 triisostearate | 30% |
| Beeswax | 5.5% |
| Olive wax | 3% |
| Alkene wax | 4% |
| Castor oil | 18% |
| Liquid paraffin | 24% |
| Peppermint essential oil | 5% |
| Ethylparaben | 0.4% |
| Chrysanthemum extract | 6% |
D. Lip balm
When adding Zinc Oxide in lip balm, use a micronized or coated grade for a smooth texture and even dispersion. Incorporate it into the melted oil phase with thorough mixing (preferably high shear) to avoid clumping. Stir continuously while cooling to prevent settling and ensure a uniform, stable balm.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Sunflower Oil | 25-28% |
| Beeswax | 15% |
| Candelilla Wax | 5% |
| Shea Butter | 10% |
| Coconut Oil | 15% |
| Jojoba Oil | 5% |
| Zinc Oxide | 20% |
| Vitamin E Acetate | 1% |
| Tocopherol | 0.5% |
| Fragrance (optional) | 0.5% |
Dosing Guidelines
A. Dosing by Application
| Products | Authorized dosage % |
|---|---|
| Sunscreen Lotions, Creams | 5-25% |
| Cosmetics Skin Care Creams, Lotions | Upto 25% |
| Paints/Coatings | 10–40% |
