SPF Testing & UVB Clinical Trials
These Clinical tests examine your ingredients within the regulatory measures for SPF in an in vivo situation allowing you to make an SPF claim on the packaging and in advertisements.
What you can expect from SPF testing:
COLIPA Method / ISO: 24444 Method – International:
- 10 healthy male and female subjects with Fitzpatrick skin number 1-3 used to investigate the skin’s Minimal Erythema Dose (MED) time period for pre and post-product treatment to calculate the sample’s SPF.
Active Phase:
- We generate a pre-treatment MED which is the minimal amount of UV light to elicit barely perceptible erythema. The product is then applied to the site and post-treatment MEDs area. The product SPF is the ratio of pre-treatment MEDs to post-treatment MEDs.
FDA Approved Method – USA / Canada:
- Similar to COLIPA method but uses different active phase MED assessments via the use of 7 time points instead of 5 as in the international methods.
Australian / New Zealand Approved Method:
- Similar to COLIPA method but uses a slightly different wavelength of UV to elicit MED.
Claims Substantiated:
- On-pack SPF rating
Further Endorsements Also Available:
- Water Resistant
- Sweat Resistant
- Sand Resistant
