Phytokeratin is a proprietary blend of soy, corn, and wheat proteins designed to be the best of all worlds. It has elements with low molecular weight for penetrating skin and hair, and it offers substantivity and film forming through the higher molecular weight molecules. As with other proteins, it is water, glycerin, and alcohol soluble, so this is for products containing water - anhydrous products are right out! Include any proteins in your cool down phase at 1 to 5%. (Having said this, LabRat suggested putting in the heat and hold phase, so I'm going to suggest that as well.)
I've used phytokeratin in my shaving lotion for ages because I want both the slip and the conditioning properties, and it's a perfect addition to a facial moisturizer or toner because it does double duty. I don't use it in my hair care products because I find anything with low molecular weight - phytokeratin and silk - tends to make my hair frizz out, but if you have dry hair that needs conditioning, then phytokeratin is a great addition to any shampoo, conditioner, intense conditioner, or leave in conditioner!
Because the hydrolyzed proteins play well with surfactants, let's add some to our facial cleanser (original post and instructions found here...)
FACIAL CLEANSER WITH PHYTOKERATIN
20% LSB or BSB surfactant (I like LSB for degreasing, use BSB if you have normal or dry skin)
10% Amphosol CG
10% aloe vera or other hydrosol
2% phytokeratin (substituted for cromoist)
0.5% chamomile extract
0.5% honeysuckle extract
0.5% Germall Plus preservative or 1.0% Germaben II preservative
up to 2% Crothix
Increase the protein to up to 5% if you like and increase the panthenol to 5% if you like. Just remove an equal amount of water.
Let's have some fun with silk tomorrow!
