Annnnnnd, you'll be happy to know I seized this opportunity to take some updated photo's and notes on my Vanilla Bars :
I gave them all a good wash and then took a layer off the top and side of each bar for colour comparison .. I found it interesting that only one batch still shows a slightly lighter interior, that being 'TCS's Pink Sugar' :
Also of note, especially since all these were made with the same formula, same batches of oils, in the same moulds, and stored in the same conditions ever since - the two lightest bars (Unscented & Black Raspberry Vanilla) have both started to show DOS (dreaded orange spot/rancid free oils) .. Something I've only ever had happen twice before in 2+ years of soaping!
The BRV only has a couple of spots on two of the bars, whereas the Unscented is so discoloured and foul smelling that I've actually thrown all but one out ..
The Unscented bar (bottom row, far left) is now seriously Yellow & 'cheesish' :
Soooo does one assume that FO can help preserve/extend the life of soap by way of acting as an antioxidant ?? I'd love to hear your thoughts on this ..
I'm afraid I've run out of time but have more pics and fragrance notes (including a surprising new favourite!) to share, so hopefully I'll get that up in the next couple of days .. Don't laugh (or hold your breath) - I'll do my best!
And just before I go I've had a couple of questions about DS's Drizzled Honey-Vanilla, which as far as I know is still available .. I absolutely hate trying to navigate their site! But just had a quick look and was able to find it on the sample list, under 'For the Love of Vanilla Collection' :D
