Overview
Sodium ethanesulfonate (CAS 5324-47-0 ) is an aliphatic sulfonate salt used industrially as a wetting agent and dispersant. Its sulfonate group provides strong surface activity, supporting emulsification and surface modification across several manufacturing processes.
In textile processing, it improves dye bath penetration and fiber wetting, enabling more uniform coloration across synthetic and natural substrates. Leather finishing operations use it to aid dispersion of treatment agents.
This ensures consistent surface coverage during tanning and coating steps. In paper manufacturing, it supports sizing formulations and surface treatment processes where controlled wetting is critical to sheet quality.
Plastics and polymer processing applications include its use as a dispersant in compounding and coating formulations. This is essential where uniform distribution of additives is required for material integrity.
Sodium ethanesulfonate is typically supplied as a white crystalline powder or as an aqueous solution. Technical grade is the most commonly available specification for industrial processing applications.
It is suited to the textile, leather, and paper sectors. Packaging is generally offered in bags or drums, with bulk quantities available for high-volume industrial procurement and supply chain needs.
