SYNTHESIS OF MELDRUM ACID DERIVATIVES PRESENTING ANTI-UVA AND BLUE LIGHT, ANTI-PIGMENTING AND / OR ANTIOXIDANT ACTIVITIES

摘要

The invention relates to the field of molecules exhibiting anti-UV and anti-pigmenting properties. More particularly, the invention relates to the use of derivatives of Meldrum's acid exhibiting anti-UVA and blue light, anti-pigmenting and / or anti-oxidant and protective activities against the cold, used alone or as a mixture as than UV filter and / or blue light. These compounds can be used in many fields of application such as cosmetics, in particular sunscreens, food, pharmaceuticals, polymers, biocontrol and protection of plants against the cold.
