This happened last Fall while I was formulating a series of products for a client.
Part of the series included 2 versions of a balm: one unscented, one scented.
The balm ingredients consisted of butters, waxes, and a combination of special fixed oils.
Pictured: batch 1 of both versions. The little S sticker on the lid is the scented version. And I know you've already guessed what the U stands for.
Hardly There, PleaseThe client was not kidding when she said lightly scented. The brief was for a 'very very light whisper of a scent – something etheric – more a feeling than an actual discernable fragrance.'
I mentally translated this to 0.08 %.
If you're doing a small batch and working with drops (even though it's not really the right way), that's about 3 drops per 100 grams of balm.
That's all it took to make such a difference in how this balm set. The above picture was taken the day after this batch was made.
A mere 3 drops of essential oil can make this kind of difference in an otherwise identical formula.
So, Why?Can I explain the exact reason for this reaction? Nope. I could maybe guesstimate a few things because of my experience and 2 new-to-me ingredients, but they would be guesstimations.
I can tell you this: take notes as you go along and your knowledge will accumulate over time.
