"Can someone convince me that FOs are safe?"
Well, can someone convince me that FOs are NOT safe?
As in most things, the difference between a miraculous cure and a poison is in the dose. As Swiftcraftymonkey notes in her lotion making / cosmetic chemistry blog, one castor bean (from whence we derive castor oil for soaps . . . or Ricin, a chemical weapon) can kill a human if ingested. It takes 80-odd castor beans to kill a duck. Castor plants around the edge of the garden seriously deter moles and gophers -- a really good thing in *my* gopher-overrun garden. I don't eat the castor beans, and my kids are old enough to know better.
I remember as a kid there was a *huge* brouhaha about "HAIR DYES CAUSE CANCER IN WOMEN!!" Turns out a woman would have to DRINK a bottle of hair dye per day for over a year to get cancer from hair dye. I don't sweat it, don't drink it, and happily cover my gray hairs. I mean, "platinum blonde" hairs!
I talk to other soapers who refuse to use FOs because they are "synthetic", "chemical", or "not natural". As has been pointed out, true floral scents are *incredibly* resource-intensive to make. MILLIONS of flowers have to be grown and harvested (mostly by hand) to make small amounts of those oils. Is that really the most environmentally favorable option? Are herbicides of pesticides being used on those flowers?
EOs are naturally-sourced, but processed/distilled/extracted into a very concentrated product -- not really in a natural state. And EOs are well known skin and bronchial irritants. I routinely see "natural" soap makers using HIGH levels of cinnamon, clove and ginger in soap, to get the scent to stick. At those levels, those oils may very well irritate body bits and pieces best left un-irritated!
Unless you're saving the hardwood ashes from your fireplace and cookstove (and, I assume, chopping all your wood by hand w/o a gas-powered saw,)and collecting rainwater for lye, our lye is a processed, lab-created chemical. And why do we prefer that? It's much less resource-intensive, and works consistently and reliably every time we use it.
As for petroleum . . . I wish more people understood this. Petroleum-derived is not inherently evil. Crude oils are carbon compounds, refined and processed many multiple times to achieve various products, the most refined being jet fuel. Every time it's refined, something is left behind. Carbon, paraffin, petrolatum, etc. Think of the difference between kerosene, gasoline, and jet fuel. Petroleum-derived means they are finding uses for those things taken out, rather than dumping them in land fills. If using paraffin and Vaseline keeps it out of a land fill, and it works for your candles and chapped skin, why is it evil? Because they got it on the way to making kerosene? Do you prefer a wood burning fireplace, or coal-fired electricity for your light source? If you want to DO something about petroleum production, lobby your congressman and find out WHY 50 different states have 45 different standards for gasoline. Wouldn't ONE standard be more efficient, less costly, and (whoops) make sense? I know, I know, congress = sense doesn't compute!
If phthalates worry you, don't use them. If FOs worry you, don't use them. If your customer base worries, don't use them. I happily use FOs, beeswax and lard in my soaps, but I flatly refuse to use GMO oils. I prefer organic, but having first-hand knowledge of THAT can of worms, I don't even sweat that. If I can get it, great. You pays your money, you makes your choice. But make sure it's a thoughtful, informed choice. Remember a majority opinion works well . . . only if you're a lemming.
I, too, prefer bright blue, cotton-candy scented soap myself, so there! Blue dye must be safer than red hair dye? :mrgreen:
