Patent ID: 7091243

Claim:
An alkoxylated ester of a dicarboxylic acid having an anti-irritating activity, measured as a reduction in intracellular leakage of sodium fluorescein, of 15% or more at 1:50 dilution or 40% or more at 1:100 dilution from a test composition containing 5% of said alkoxylated ester; and having the formula (I): where —COR 1 CO— is a dicarboxylic group of an aliphatic dicarboxylic acid and R 1 is an alkyl group, saturated or unsaturated, straight chain or branched, cyclic or acyclic, having 0 to 20 carbon atoms, or —COR 1 CO— is a dicarboxylic group of an aromatic dicarboxylic acid and R 1 is an aromatic nucleus of the aromatic dicarboxylic acid, having 6 to 20 carbon atoms; R 2 O— and R 4 O—, which may be the same or different, are alkoxylated moieties of the formula x ranges from 0 to 200 and y ranges from 0 to 200; R 3 and R 5 , which may be the same or different, are independently alkyl, alkylaryl, or arylalkyl groups, straight chain or branched, saturated or unsaturated, having, containing from 6 to 30 carbon atoms, or hydrogen with the proviso that not more than one of R 3 and R 5 can be hydrogen; and further wherein R 3 and R 5 have 16 to 22 carbon atoms, or x/y ranges from 1 to 2.5, or the weight percentage of the ethoxy groups in the groups (R 2 O) and (R 4 O) with respect to the molecular weight of the groups R 3 O(R 2 O)— and R 5 O(R 4 O)—, respectively, is over 20%.
