The influence of dimeric surfactant on the transformation of amorphous calcium phosphate

The influence of the cationic dimeric surfactant, ethanediyl-1, 2-bis(dimethyldodecylammonium) bromide (12-2-12) on the transformation of amorphous calcium phosphate (ACP) was investigated. ACP was precipitated in the absence and presence of 12-2-12 surfactant monomers or micelles of various sizes and shapes. Both, 12-2-12 monomer and micelles promoted ACP to crystalline phase transformation, the size of the effect decreased in order monomers > spherical micelles > wormlike micelles. The proposed mechanism involves surfactant adsorption (electrostatic and hydrophobic) at the surface of ACP growing particles which modifies the aggregation kinetics and transformation to crystalline phase.
