BIO-SOFT N-411 is used in the detergent industry. It is both oil soluble and water dispersible. BIO-SOFT N-411 is useful as a surfactant for emulsion degreasers, laundry pre-spotters, dry cleaning products, paint strippers, and other hard surface cleaners. BIO-SOFT N-411 is an effective emulsifier for petroleum based aliphatic, aromatic and chlorinated solvents, pine oil, terpene hydrocarbons such as dlimonene and its isomers such as orange oil. Dilutable microemulsion concentrates can be easily formulated using BIO-SOFT N-411. In cosmetic and personal care products, this ingredient can be used in bath products, cleansing products, shampoos and hair conditioners, and can improve their ability to wet the skin and hair.

Storage & Handling

Storage & Handling
  • Non-Bulk Storage Recommendations: BIO-SOFT N-411 should be stored in closed containers and kept in a cool, dry place away from incompatible materials (see Section 10 of the SDS). If material is frozen it should be heated gently and stirred to ensure it is homogeneous prior to use
  • Bulk Storage Information: BIO-SOFT N-411 should be stored in 316 stainless steel or fiberglass with a corrosion liner. Mild agitation is recommended while storing to maintain homogeneity. Material should be stored between 85-105°F (29-41 °C). An internal hairpin coil of 316 stainless steel with low pressure steam (under 50 psig) should be used if heating is required. Pumps, pipes and transfer lines should be 316 stainless steel.
