Uses
Used in photography (developer); [www.ci.tucson.az.us/arthazards/medium.html] Used as a textile stripping agent, fixing agent for keratin-containing fibers, flotation chemical in lead-zinc ores, cosmetic preservative, fungicide in mushroom cultivation, and to protect color pictures exposed to high humidity against fading and staining; [HSDB]
Textiles (Fiber & Fabric Manufacturing) [Category: Industry]
Textile stripping agent
One of several mixtures of sodium formaldehyde hydrosulfite and sodium formaldehyde bisulfite used as discharges and stripping or reducing agents in dyeing and other textile operations. In some cases the zinc derivatives are used. Derivation is by the action of formaldehyde on aqueous sodium hydrosulfide or from zinc formaldehyde, sodium dioxide, and sodium hydroxide. /Hydrosulfide-formaldehyde/
