Better crafting through chemistry, Anna asks: Do you know which humectants except for glycerin doesn´t wash off? Hydrolyzed proteins? Hyaluronic acid? Different quats?
Great question! I have read that sodium lactate and sodium PCA wash off, but I've not heard that glycerin washes off. Hydrolyzed proteins and cationic polymers are substantive, meaning they will adsorb to your skin and hair and resist being washed off. (Click here for adsorption and substantivity.)
As an aside, hydrolyzed proteins and (most) cationic polymers aren't actually humectants in that they don't draw water from the atmosphere to your skin. Hydrolyzed proteins tend to film form on your skin or penetrate your hair to moisturize from the inside. Cationic polymers are substantive, meaning they form a very light film on you rhair or skin through attraction of negative and positive charges. Only honeyquat is considered also a humectant.
making a facial serum, Kirsten asks: Label printing has been a big obstacle for me. I want a professional looking finish, and am not sure what sort of label printer would give me that. Or if I should get labels done by a commercial printer. The only problem with that is having to then always use the same ingredients.... any advice? I do want to be able to sell a small amount of my product.
I currently use an Epson Workforce 4020 not-all-in-one printer and I love it. The ink is waterproof, so I don't need to use a spray or anything to keep it looking nice, and it would be extra-waterproofy if you used a waterproof label like these ones from Avery. (That's if you need waterproofing for things like body washes or shampoos. Non-waterproof ones will work well with lotions and whipped butters and the like.) Get a program to make a template label - Avery has them at that link or you could use Word, Print Shop, Publisher, and so on - and design something awesome! If you can't design something awesome - like me - find someone and pay them to design something awesome as a template for you. It is worth the money to get something that represents you as a formulator and your company that you can use for all time, even when you get big and famous and forget about us little people!
I know it's not an option for someone selling products, but I find putting packing tape over a label keeps it looking lovely in the shower!
Dear readers, please share your thoughts on how you make labels! I'm sure you have something wonderful to add to this conversation!
