I haven't seen evidence that Sodium Lauryl Sulfoacetate is teratogenic. It's very different from Sodium Lauryl Sulfate, which is a small molecule ingredient, and is capable of penetrating the skin. SL Sulfoacetate is a large molecule that's derived from coconut and palm oils and is supposed to be a safer, skin-friendly surfactant for both skin and hair. I'm not saying it's perfect, but it's better than the other alternatives... Same thing goes for Disodium Laureth Sulfosuccinate - maybe not perfect, but better than anything with sulfates..
Getting a cleanser that has lots of suds without one of these ingredients is tough. You might try Burt's Bees, but some of their products have too many essential oils and extracts for me.
As for Aloe, I do know that you're not supposed to ingest it during pregnancy (due to the possibility of inducing uterine contractions), so I'm surprised that it would be in their products. However, now that I'm going back to look at the other pregnancy lines I considered (Juice Beauty, etc..), ALL of them have it!! Granted, it's a very tiny concentration, but still.
I've heard conflicting things regarding Tea Tree and Lavender, but again, why risk it?
Anyway, I totally understand you not wanting to have ANY of these things in your products. Again, I'd love to know what you decide on, so please keep us updated!
