We have three phases: the heated water phase, which contains anything that is water soluble and can stand heat; the heated oil phase, which contains everything oil soluble that can stand heat; and the cool down phase, into which we put everything else.
How do you know into which phase you should add an ingredient?
Emulsification: What's that then?
hyaluronic acid at 0.1% in the heated water phase. I could add it at 0.1% to the water phase, or I could make the gel and use that at 10%, which works out to 0.1% active ingredient. (This formula is originally from Lotioncrafter and is used here with permission.)
BASIC HYALURONIC ACID GEL
98.5% distilled water
1% LMW hyaluronic acid powder
0.5% liquid Germall Plus
I sprinkled in the hyaluronic acid powder, mixed well by hand until the powder was wet, then left it alone for three hours and came back to a lovely looking gel! It should be completely clear and doesn’t feel sticky on your skin. You can use this neat or use this in products. (Using 10% hyaluronic acid gel = 0.1% hyaluronic acid in your product.)
If two humectants are good, three might be better, so let's add some sodium lactate at 2%! (I'm using the 100% powder in this product, but you can use the 60% liquid, if that's what you have.)
You know I love my hydrolyzed proteins, so I've added hydrolyzed quinoa protein as a film former and skin conditioner. And I have to have allantoin at 0.5% as it's a great barrier protector as well as skin soother.
I’m a huge fan of panthenol, in this case powdered dl-Panthenol, Vitamin B5, which has been shown to help increase skin hydration and behave as a humectant and anti-inflammatory while helping skin’s wound healing properties. And I'm adding liquid calendula extract at 5% as an anti-inflammatory and anti-oxidant.
olive derived squalane, part of the unsaponifiable part of olive oil found in our skin so it sinks in quickly to moisturize. I've been using this as the base of just about every facial product I make as it's light and non-greasy. It leaves a nice dewy-ness to my skin that I don't seem to get with other oils.
As my oil, I like unrefined rosehip seed oil as it contains beta carotene, the precursor to Vitamin A, that helps with hyperpigmentation of our skin to promote a more uniform skin colour. It's light and non-greasy, which is a great thing for moisturizers! I used 5% as it's quite brightly orange, and I don't want to turn this into a custard! (Although facial custard does sound kinda nice, eh? Hmm...)
Sepilift DPHP (INCI: Dipalmitoyl hydroxyproline), an ECOcert and Natrue certified ingredient at 1% to 2% in the heated oil phase as an anti-aging ingredient that may stimulate collagen synthesis to plump skin and lips.
Into the cool down phase, I added Antarcticine* (INCI: Water, Pseudoalteromonas Ferment Extract, Salicylic Acid, Sodium Hydroxide), an ECOcert ingredient used at 3% to 5% to increase skin hydration, increase levels of collagen and elastin to reduce the depth and appearance of fine lines and wrinkles, as well as enhance wound healing.
And I added Regu-scence* (INCI: Asparagus Officinalis Stem Extract), an ECOcert ingredient used at 1% to 3% in the cool down phase to help create a more even skin tone and reduce the signs of aging, like thinner skin.
Simulgreen 18-2 (INCI: Hydroxystearyl Alcohol and Hydroxystearyl Glucoside), which we met yesterday. To make it more stable, I need to add a fatty alcohol like cetyl alcohol or cetearyl alcohol. I added behenyl alcohol as a thickener and stabilizer at 2% in the heated oil phase as I like the dry, matte feeling it offers. You could use either of the other fatty alcohols, if you wish. Cetyl will make it a bit more oily - not a huge amount, but enough that you'll notice it - and cetearyl will make it a bit thicker and waxier.
Any time we use water, we need to use a preservative. My favourite is liquid Germall plus at 0.5% in the cool down phase as it’s a broad spectrum preservative that will help combat microbes like bacteria, yeast, and mold.
I know some of you are thinking about changing the preservative. You can do that, but make sure it's a broad spectrum preservative - meaning one that will combat all the potential contamination - and it can work with the ingredients we're using. Check out the preservative comparison chart in this post or the preservatives section to make sure it'll work with this formula. I know how it works with liquid Germall Plus as that's how I've made this quite a few times, but there's no guarantee it'll work with what you have.
