Surfonic JL-80X is a good alternative to Triton X-100. Surfonic JL-80X has all the same basic properties as Triton X-100, but is safer to use (See Health and Safety Notes below). It may be used in most formulas as a direct replacement. For those situations where it does not work as well as needed, consider a mixture of both Tritons. Keep in mind that Triton X-100 is not half as bad for your health as most of the chemicals already in your lab, it's just a good practice to always use the safest products available.
Health and Safety Notes: For the past few years now, Chris Stavroudis, who writes a Health & Safety column for the WAAC newsletter, has brought to the attention of conservators that Triton X-100 has some potential health concerns associated with its use. Chris has pointed out that Triton X-100 is made from, and decomposes back into, octylphenol, which has been demonstrated to mimic the hormone estrogen in a number of animal species at extremely low levels of exposure. Although there is no direct evidence of any health hazard associated with the use of Triton X-100, caution is recommended when using it. Due to the fact that some risk may be involved with the use of Triton X-100 we do believe women and particularly women in their child bearing years, should be especially concerned, and should avoid all exposure to Triton X-100. Because of these health concerns, we highly suggest you consider the replacement of Triton X-100 whenever possible with the safer version, Surfonic JL-80X. Most importantly, do as we always recommend, READ THE MATERIAL SAFETY DATA SHEETS FOR YOURSELF.
