G-Salt (Sodium Sulfate / Glauber's Salt)

G-Salt – Sodium Sulfate / Glauber’s Salt (Industrial Grade for Batik)

G-Salt, in its anhydrous form, is a white, free-flowing crystalline powder commonly used in textile dyeing, including batik production. It helps improve dye penetration and allows for even color distribution across fabric, especially when working with reactive dyes like turquoise.

Unlike table salt, Anhydrous Sodium Sulfate is pH-neutral, iodine-free, and does not affect the softness or texture of the fabric. It acts as a leveling agent and electrolyte, helping dyes bond evenly to fibers and supporting proper dye exhaustion before fixation. While it’s not a dye fixative, it plays a vital role in preparing fibers for color setting.

Key Benefits/Advantages of G-Salt:

• Promotes even dye absorption in batik and textile dyeing
• Controls dye flow and reduces patchiness
• Softens water and improves dye bath performance
• Excellent drying aid and bulking agent in powders
• Non-hygroscopic, long shelf life, and easy handling

Uses/Applications of Anhydrous G-Salt (Sodium Sulfate):

• Batik and textile dyeing: Enhances dye uptake and levels out color
• Reactive dye systems: Especially useful for turquoise and other bright shades
• Powder detergents: Used as a filler, drying agent, and water softener
• Crafts and pigments: Improves blend texture and consistency
• Cleaning products: Adds bulk and assists in de-greasing formulations
