Sodium Lauroyl Sarcosinate - Safe Handling

Hi All, 

I'm in the process of developing my own line of personal care/hygiene products. Since I'm not selling anything yet, I'm trying to keep costs down by doing my formulation work at home in my kitchen. I recently purchased a small sample of what appears to be CRODASINIC LS95 which is a 95% ASM sodium lauroyl sarcosinate powder. I've worked with other powders before, such as SMC taurate and SCI, and I wear an N95 mask and nitrile gloves, and do the mixing and heating near a window with a window box fan blowing out. My concern is that, according to the MSDS of the CRODASINIC powder, it's possibly fatal if inhaled. While I'm careful to avoid kicking up dust while scooping out powder, I worry if my safety measures are adequate. Have any of you worked with this stuff? Exactly how toxic is it? Do I need to worry about dust that escapes the bag and gets on the floor (and on other stuff) in my kitchen? It's not like I'm working with large quantities here, but I don't want to hurt anyone. Any advice is appreciated.

Thanks,

-TB

  • @Bill_Toge: You have worked with the powder? Do you think my safety precautions are adequate then?

    The question is, WHY is it fatal if inhaled? Some things that are fatal if inhaled have no minimum dose (eg, blue asbestos).

    @thebrain I have, and I would say your precautions are more than adequate; our precautions consisted of a dust mask and safety glasses for large-scale dispensing, which is standard for all bulk powders

    @Belassi the other questions are: at what dose is it fatal, and at what particle size? also, how does this compare with the actual material?

    over the years I've found that MSDSs are not always helpful in themselves, as materials with very dissimilar hazard profiles are often lumped together under the same category

    as a recent example, we used hexylresorcinol in a plant trial, which turned out to be irritating and extremely unpleasant when inhaled (even with a dust mask!), but it was given the same precautionary statements as many other more benign substances

  • @Bill_Toge: Thank you for your feedback. I feel a little better now knowing that my safety measures are adequate.
