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.
A 16 mm "reel" is 400 feet (122 m). It runs, at sound speed, approximately the same amount of time (11–12 minutes) as a 1,000-foot (305 m) 35 mm reel. A "split reel" is a motion picture film reel in two halves that, when assembled, hold a specific length of motion picture film that has been wound on a plastic core.
