Test for the determination of UVA photoprotection in vivo
| Regulatory reference: | ISO 24442:2011 |
| Claim: | UVA protection and PA rating |
| Application field: | Sunscreen creams, sticks and cosmetic products. |
| Description of the test: | Method that is based on the persistent darkening responses of the skin pigmentation of the subjects in order to evaluate the UVA sun protection factor (UVAPF) of the sun product. |

Test of reduction of SPF caused by salt water
| Regulatory reference: | ISO 24444:2010 of 15/11/2010 and Colipa test method 2006 for the determination of the WATER RESISTANCE. Test performed according to modified COLIPA 2005 method |
| Claim: | Salt water resistant |
| Application field: | Finished sunscreen products. |
| Description of the test: | Test performed on 10 volunteers, by comparison of pre-wash and post-wash SPF. The treatment includes two washes, one in salt water, performed by irroration with 1M NaCl solution by a pressureless drop shower, and one in fresh water. If the reduction of protection is greater than 50% the product isn’t considered to be “Salt Water Resistant”. |

Test of reduction of SPF caused by sand
| Regulatory reference: | ISO 24444:2010 of 15/11/2010 and Colipa test method 2006 for SPF. |
| Claim: | Sand resistant |
| Application field: | Finished products. |
| Description of the test: | In vivo test on 10 subjects. Comparison between SPF of sun product and the reduction on protection cause of double sand static contact of 20 minutes in this sequence: contact, techanical cleaning, contact and final mechanical cleaning before the exposure to the solar multiport simulator. If the reduction of protection is mayor than 50% the product isn’t “sand resistant”. |
