Dioctyl Sulfosuccinate Sodium Salt is a high-efficiency anionic wetting & penetrating surfactant with ultra-low surface tension, fast penetration and low foam.
Widely used as stool softener API and pharmaceutical excipient. Industrial OT-70 liquid is applied in textile printing, leather processing, pesticide adjuvant, coating wetting agent. Good compatibility with nonionic surfactants, biodegradable and mild.
Application Areas
1. Pharmaceutical Industry
Active Pharmaceutical Ingredient (API) for Laxatives: Softens stools when taken orally by reducing the surface tension of intestinal fluids, allowing water to penetrate and soften the stool. It provides mild laxative effects without severe irritation.
Pharmaceutical Excipients: Acts as a wetting and dispersing agent in ointments, suspensions, and topical lotions. Serves as an adjuvant in eye drops to improve drug permeation and absorption.
2. Textile Printing and Dyeing Industry
Pretreatment Penetrants: Ensures rapid wetting during desizing, scouring, and bleaching for cotton, synthetic fibers, silk, and linen.
Dyeing Penetrants & Leveling Agents: Shortens dyeing time and eliminates uneven dyeing (mottling).
Wetting Agents: Prevents screen clogging in printing pastes.
3. Leather Chemicals
Hide Soaking Aids: Rapidly penetrates hide fibers to accelerate degreasing and softening, effectively reducing the processing time of the soaking operation.
4. Coatings, Inks, and Adhesives
Wetting and Leveling Agents: Eliminates craters and pinholes; enhances pigment dispersion. Reduces surface tension in water-based inks and varnishes while improving substrate adhesion.
5. Agrochemical & Fertilizer Adjuvants
Penetrants and Spreading Agents: Used for aqueous solutions, Emulsifiable Concentrates (ECs), and foliar fertilizers. Helps spray solutions rapidly penetrate plant leaves, improving absorption while reducing rainfall wash-off.
6. Daily Chemicals & Personal Care
Wetting Agents: Applied in low-foam dishwashing detergents, industrial spray cleaners, and facial cleansers.
Cosolvents: Formulated for aerosol products.
7. Specialty Industrial Applications
Paper deinking and papermaking wetting agents.
Wetting agents for electroplating pretreatment.
Penetrating aids for mineral flotation.
Dispersing and wetting aids for lithium battery slurries.
Package
