Sourcing Thiourea Dioxide (TDO)? ChemicalDekho connects you with specialized reduction chemical manufacturers. Access high-purity, stable reducing agents for textile processing and paper recycling.
Thiourea Dioxide (CAS 1758-73-2) is gaining popularity as a safer, more effective alternative to Sodium Hydrosulfite (Hydros). It has high reduction potential, excellent heat stability, and does not release sulfur odors during use. It is widely used for 'Reduction Clearing' of dispersed dyes on polyester and de-inking waste paper pulp.
Listings feature 99% purity material with low iron content to ensure brightness in bleached fabrics.

Self-heating in large quantities; may catch fire. Causes skin and eye irritation. Harmful if swallowed. Keep away from moisture and heat.
Yes. TDO is 5x stronger reducing power per kg, stable in storage (doesn't decompose like Hydros), and odorless. However, it is more expensive per kg.
TDO itself is odorless. Unlike Hydrosulfite which smells of rotten eggs (sulfur), TDO makes the workplace much more pleasant.
No. Thiourea is toxic and suspected carcinogen. Thiourea Dioxide is a different chemical (oxidized form) and is much safer to handle.
It effectively removes ink particles from recycled paper pulp (de-inking) without yellowing the fiber, creating brighter recycled paper.
