So, I am mulling over the SDS for Liquid Wrench's Penetrating Oil, and I decide to see what CAS "1581740-29-5" leads to, but no dice. I instead lookup the constituent hydrocarbon to see if it has particular uses. Thats:
What I'm finding is this: https://pubchem.ncbi.nlm.nih.gov/compound/10407
Which says it's Beta-Farnesene, https://en.wikipedia.org/wiki/Farnesene
They put 5-10% of this into the blend, but why? As an insect repellent? I understand that SDS does not have to report everything, yada yada.
