Analysis of Furocoumarins

Solar products – biodegradability

Ready biodegradability • According to OECD 301F / ISO 9408, OECD 301A / ISO 7827, OECD 301D / ISO 10707 and OECD 301E and ISO 7827 • Duration 28 days – can be extended for up to 60 days if required

Inherent Biodegradability • According to OECD 302B / ISO 9888 Deadlines: 8 to 10 weeks upon receipt of samples

Biodegradability in seawater According to OECD 306 / ISO 16221 (adaptable in manometric respirometry for products that are poorly soluble in water)
