NP-40 (also known as Tergitol-type NP-40 and nonyl phenoxypolyethoxylethanol [1]) is a commercially available detergent with CAS Registry Number 9016-45-9. NP-40 is an ethoxylated nonylphenol for non-ionic surfactants and can act as emulsifier and demulsifier agent.
Nonidet P-40 is a nonionic, non-denaturing detergent. Its official IUPAC name is octylphenoxypolyethoxyethanol. Nonidet P-40 is sometimes abbreviated as NP-40, but should not be confused with a different detergent by the same name NP-40 , nonylphenoxypolyethoxyethanol of the Tergitol NP series of Dow Chemicals.
IGEPAL CA-630 has HLB of 13.4, similar to that of Triton X-100 (13.4) and thus belongs to the detergent range (HLB 13-15); this is significantly less than 17.8 of tergitol NP-40 or 16.7 of Polysorbate 20 (also known as Tween 20), which both belong in the solubilizer range (15-18) of HLB. [2] Ca-630 is completely miscible with water.
Triton X-100 (C 14 H 22 O(C 2 H 4 O) n) is a nonionic surfactant that has a hydrophilic polyethylene oxide chain (on average it has 9.5 ethylene oxide units) and an aromatic hydrocarbon lipophilic or hydrophobic group.

Unlike a four-stroke engine, the crankcase of which is closed except for its ventilation system, a two-stroke engine uses the crankcase as part of the induction tract, so oil must be mixed with gasoline to be distributed throughout the engine for lubrication. [1] The resultant mix is referred to as premix or petroil. [2]
