So I'm wanting to better understand MSDS for EOs and other soaping ingredients. Seems like it would be good practice.

At random I pulled the MSDS for Anise (from NDA).

When something is listed as or contains an element that is "carcinogenic" (cancer causing) what kind of exposure is assumed here? If it's inhaled, eaten, put on skin, or?

Check it out: http://www.newdirectionsaromatics.ca/ms ... armsds.htm

Karri, I believe most MSDS assume that if a product is used and/or added to products that are used on the skin, then that is the most likely way the carcinogenic compound will be introduced to the body. Likewise, if something is a gas, then it would assume inhalation. You have to keep in mind though, that most of the known carcinogens came about through testing on mice and other animals at extremely high dosages. The MSDS you linked to states that there is a "trace" amount so the chances of it causing cancer are miniscule if the product is used properly and at recommended usage amounts.

Yes I'd agree as well re such minuscule amounts ... but it's got me wondering what's in all the other popular EOs :)

Do you all abide by the rule for having a fire extinguisher near by when soaping? To my mind if for some bizarre reason say the oils catch fire wouldn't putting a lid on the pot be the best solution? (If you can get near it of course.) Or is the fire extinguisher mentioned by some due to EO's igniting somehow? (Seems unlikely but...)

Some books / soap experts suggest a fire extinguisher and some don't so I've always wondered about this discrepancy.

I keep a fire extinguisher in my kitchen already for safety reasons, but not because of soaping. Sometimes my hubby cooks... :lol: :lol: :lol:
