Potassium isostearate

Potassium isostearate (CAS 68413-46-7) is the potassium salt of isostearic acid; a soap-type emulsifier and surfactant.

Where is Potassium isostearate used?

• Personal care: creamy, stable emulsions in cleansers, shaving preparations and skin creams
• Textile and leather: wetting and softening agent for fiber lubrication and surface uniformity
• Coatings and adhesives: dispersant and emulsifier for pigment slurries and polymer dispersions
• Leave-on products: humectant component for moisture retention and skin feel
• Its branched fatty acid chain resists crystallization, so liquid and semi-solid systems stay stable at ambient temperatures.

Good to know: Unlike conventional potassium stearate, its branched chain resists crystallization. Cosmetic-grade material meets purity requirements for personal care manufacturing.
