| Regulatory reference: | ISO 24443:2012 |
| Claim: | Broad spectrum protection (UVA encircled) |
| Application field: | Sunscreen creams, sticks and cosmetic products. |
| Description of the test: | Determination of the UVA protection and critical wavelength according to the ISO guideline for broad spectrum protection testing. |
Microscopic analysis of the aggregation of filters
| Regulatory reference: | Proprietary method |
| Claim: | Control of the aggregational state of physical filters |
| Application field: | Sunscreen creams, sticks and cosmetic products. |
| Description of the test: | Microscopical analysis and high resolution imaging of the aggregation of physical filters. Includes measurement of the size of aggregates, if present. |
Analysis of the protection granted by sunscreens in the high energy visible spectrum (HEV/blue light 400-500 nm)
| Regulatory reference: | Proprietary method based on ISO 24443 |
| Claim: | Protects against the high energy visible (HEV) spectrum or Blue light protection |
