Abstract:
The present invention relates to a process for the solidification of hexyl 2-[4-(diethylamino)-2-hydroxybenzoyl]benzoate (INCI diethylamino hydroxybenzoyl hexyl benzoate, DHHB), wherein the process comprises the step of (a) applying a shear rate of 800 s−1 or more to liquid hexyl 2-[4-(diethylamino)-2-hydroxybenzoyl]benzoate and (b) adding seed crystals of hexyl 2-[4-(diethylamino)-2-hydroxybenzoyl]benzoate.
