Uses

(Fluorescent brightener 71)Fluorescent (optical) brighteners are known for their characteristics of protecting baculoviruses against deactivation by UV light and enhancing the activity of these agents as microbial insecticides on hosts and semipermissive hosts. Fluorescent brighteners improve the bioinsecticidal activity of Anticarsia gemmatalis nucleopolyhedrovirus.

IMPROVED OPTICAL BRIGHTENING AGENT FOR DETERGENT FORMULATIONS AND A PROCESS FOR PREPARING THE SAME

The present invention relates to a process for preparing disodium 4,4'-bis(4-anilino-6-morpholino-s- triazin-2-ylamino)-2,2'-stilbene disulphonate in the β crystal form, the process comprising subjecting disodium 4,4'-bis (4:anilino-6-morpholino-s-triazin-2-ylamino)-2,2'-stilbene disulphonate in the a crystal form to steam distillation. It also discloses a process to get formulations based on disodium 4,4'-bis(4- anilino-6-morpholino-s-triazin-2-ylamino)-2,2'-stilbene disulphonate, with substantially lower content of the hazardous amines such as aniline and morpholine.
