@jodym , when I first started making soap in 2023, I started out with M&P. I bought all my supplies on Amazon, including essential oils. I just looked at my purchase history and I did purchase one 4oz bottle of SIVA's lavender essential oil. It seemed to work just fine- that said, I only used it in M&P.
It seemed strong enough and it was reasonably prices. It looks like I paid $9.99 for 4 oz. There were other brands of lavendar EO on Amazon that cost $9.00 for 1 oz (and even $9.99 for .5 oz). I assume that there must be a difference in quality. Since I have never again purchased lavender essential oil, I don't have anything to compare it to. Since I've started to CP, I only buy Fragrance Oils. I understand that EO's don't make it through the saponification process quite as well, and since you have to use 2x as much in CP as in M&P, I only buy FO's.
I just looked on Wholesale Supplies Plus. They have lavender EO 40/42 for $19.95 for 4oz (on sale for $15.96 at this moment for 4 oz) and lavender EO 30/32 for $51.45 (on sale $41.16 for 4 oz ) and Bulgarian lavender for $28.95 (on sale $22.86 for 4 oz). If you buy a 16oz bottle, the prices are alot less.
I don't really have anything to compare my lavender essential oil to. On Amazon, SIVA has just under 12K ratings and they get 4.5 out of 5 stars. However, it could have been bought for purposes other than soaping. It looks like alot of ratings were for essential oil being used in diffusers.
So, I would say SIVA is reputable for at least some purposes. I stopped buying on Amazon when I learned that the coconut essential oil I bought (which was $9.99 for 4 oz) could not have been essential oil since that doesn't really exist

- or if it does, it would be astronomically expensive.
If you've used lavender EO in the past, and you know what you should be able to expect, then you don't have much to lose by trying it as Amazon lets you return purchases within a certain timeframe.
