Nonidet-P40 is an anhydrous liquid nonionic surface- active agent produced by the reaction of octyl phenol with 8.5-9.5 moles of ethylene oxide. Nonidet-P40 (NP-40) is a nonionic surfactant used in the isolation of membrane complexes. This product has been reformulated to be eco-friendly. The only observable differences are that the viscosity and handling characteristics are somewhat modified. Due to its nonionic structure, this product is compatible with anionic surfactants and is stable in the presence of acids, bases, and salts. It should not be mixed with concentrated oxidizing or reducing agents since the mixture of these compounds with organic compounds could form a potentially explosive mixture. Nonidet-P40 is an effective emulsifier for solvents such as xylene.

Handling and ToxicityNonidet-P40 is regarded as non-hazardous. However, it is considered to possess low acute oral and skin penetration. It should not be used in products for internal use. Caution: This product causes eye irritation. Direct contact would likely result in corneal injury which might persist for a week or longer. Permanent damage is not likely to occur. However, if in contact with skin or eyes, flush with excess water and consult your physician.
StorageNonidet-P40 nonionic surfactants are stable non-corrosive products in their anhydrous state. They can be stored in plain steel tanks with piping, valves, and pumps of the same metal. Aqueous solutions of Nonidet-P40 must be stored in stainless steel or plastic lined tanks. The octyl phenol-ethylene oxide adducts are slightly hygroscopic. Where necessary, guard against atmospheric moisture pick-up, an inert gas blanket may be used.
