Weekend Wonderings: Compensating for evaporation, adding water soluble ingredients to a serum, and citronellyl methylcrotonate.
In this Weekend Wonderings comment post, Anitra asks: This one's related to our heated water phases; When compensating for evaporation, do we need to compensate for any of the goodies (panthenol, glycerine, aloe, etc.) added to the heated water phase as well? Or are we just losing water? I've assumed the former, but thought I'd ask.
In last weekend's Weekend Wonderings we took a look at compensating for evaporation, so your question is a logical extension of that! We are losing the water, for the most part. Some ingredients are quite volatile and will evaporate quite quickly - alcohol, for instance - but most will only lose the water and leave the solids behind. When we get something like aloe vera, we will lose some of the water, but the solids - polysaccharides, amino acids, and polyphenols - will be left behind.

In the same post, Marjo asks: I make the dimethicone cyclomethicone serum too and was wondering if there is a way to add polyquat to it (since that is water soluble?) I use regular dimethicone.
To add water soluble ingredients to your serum, you'll need an emulsifier. You can turn it into a lotion type product by adding an appropriate emulsifier - for instance, BTMS-50 might be a good idea if it's a hair product - but it will change the nature and skin/hair feel. You could consider using an emulsifier made for silicones - Lotioncrafter Serum SE, for instance - which would keep the consistency as a serum.
I wasn't sure which polyquat you were referring to, so the information here is a bit generic.
If this is for your hair, consider using two products. A leave in conditioner with the polyquat in it and a serum. In an ideal world, we be able to make multitaskers that were awesome, but I have found that using two separate products is easier to formulate and still makes my hair happy!
In the Weekend Wonderings comment post, Simone asks: Hi Susan. I was wondering if you or any of your 'followers' have used a product called SINODOR®, made by Givaudan. INCI Name: Citronellyl Methylcrotonate. It is supposed to neutralise odours of the base product...I have issues with the fragrances of Chamomile and Witchhazel and some oils. My husband says that some ("a lot") of the products I make have a chemical smell to them (unrefined Shea butter, being one of the culprits) rather than a fragrance. Need I say that I am only making for my family at present, until I get this perfume issue sorted.
I'm wondering why you don't just use a fragrance or essential oil in your products? I find a lot of what I make smells a bit earthy - which I hate! - but 1% fragrance or essential oil can make a huge difference. From what I can tell, this ingredient appears to be used in "natural" deodorants. I haven't tried it.
Has anyone tried this ingredient? Tell us what you think!
