APPLICATIONS
SunscreensDay creamsMakeup with SPF
Used in combination with UVA absorbers in sun protection formulations. Excellent for water-resistant, high-SPF products.
DESCRIPTION
One of the newest products in the sunscreen filter line. A UVB-range sunscreen filter typically used to boost the effectiveness of other filters, especially octyl methoxycinnamate. It also improves water resistance. Octocrylene has good UVB absorption plus additional absorption in the short-wave UVA II spectrum. Maximum absorption occurs at 303 nm.
Practical formulation guide
Usage level: Up to 10 % if used alone, or 7–10 % when combined with other sunscreen filters.
How to use and incorporate: Mineral filters (zinc oxide, titanium dioxide): disperse in the oil phase with a dispersing emollient (for example C12-15 alkyl benzoate) and homogenize with high shear. Organic filters: dissolve in the hot oil phase until fully dissolved.
Formulation tips:
- The SPF and UVA protection of the finished product depend on the whole formula and can only be claimed after testing the final product.
- Combine UVA and UVB filters and use film formers to improve water resistance.
- Before scaling up, make a pilot batch and run a stability test (cycles at 4 / 25 / 45 °C/39 / 77 / 113 °F for 4 weeks, checking odor, color, pH, viscosity and separation) in the final packaging.
Compatibility: Compatible with cosmetic emollients, silicones and emulsifiers. Some organic filters (avobenzone) require photostabilizers.
Storage: In tightly closed bottles, in a cool, dry place.
Precautions: None in particular; do not ingest and avoid direct, prolonged contact with skin.
Technical information for formulators: This sheet describes industrial uses of the raw material in the development of cosmetic products. It is not an efficacy claim for any finished product. The person responsible for the formulation must validate the concentration, compatibility and claims of their product in accordance with applicable regulations.
