Abstract
A cosmetic ingredient, that consists of a solution of at least one extract of karanja oil including pongamol (CAS 484-33-3) and karanjin (CAS 521-88-0) in at least one solvent selected from the group of the diesters having the following formula (I), or mixtures thereof: In which: n is from 0 to 19; R and R′, which may be identical or different, are alkyls derived from an esterification by a linear or branched alcohol of molecular formula CxH2x+2O, x being from 1 to 30, from 1 to 20, and from 1 to 10. “R” is either a hydrogen atom or a C1-C3 alkyl group, which also relates to a process of selective precipitation, to a cosmetic formulation and also to the uses thereof.
Claims16
A cosmetic ingredient, that consists of a solution of at least one extract of karanja oil comprising pongamol (CAS 484-33-3) and karanjin (CAS 521-88-0) in at least one solvent selected from the group of compounds having the following formula (I), or mixtures thereof:
- in which:
- n is from 0 to 19;
- R and R′, which may be identical or different, are alkyls derived from an esterification by a linear or branched alcohol of molecular formula CxH2x+2O, x being from 1 to 30,
- R″ is either a hydrogen atom or a C1-C3 alkyl group.
A process of selective precipitation of pongamol (CAS 484-33-3) in a karanja oil comprising pongamol (CAS 484-33-3) and karanjin (CAS 521-88-0), wherein:
- 1) at least one step of addition to said at least one karanja oil of at least one solvent selected from the group of the diesters having the following formula (I), or mixtures thereof:
- in which:
- n is from 0 to 19;
- R and R′, which may be identical or different, are alkyls derived from an esterification by a linear or branched alcohol of molecular formula CxH2x+2O, x being from 1 from 30,
- R″ is either a hydrogen atom or a C1-C3 alkyl group;
- said addition having the effect of forming a light phase in the form of a solution and a heavy phase in the form of a precipitate;
- and
- 2) at least one step of separation of the two phases obtained.
