I found this formula - Shiny locks intensive conditioner - so I tried it with a few small changes. I find it wise to make the first batch as close to or completely as written as this will give me a sense of what success should look like. If I go messing with it before I've even tried it, then I'll never know when it's right.
SHINY LOCKS INTENSIVE CONDITIONER
HEATED WATER PHASE
84.5% distilled water
2% stearamidopropyl dimethylamine
0.3% citric acid
0.5% panthenol (powder)
3% cetrimonium chloride
HEATED OIL PHASE
7% cetearyl alcohol
COOL DOWN PHASE
0.5% liquid Germall Plus
1% fragrance oil (I used guava fig from Windy Point Soap*)
1. Heat heated water phase to 65˚C.
2. Heat oil phase to 65˚C.
3. Add the oil phase to the water phase using a high shear mixer, like an immersion blender. I used the MiniPro Mixer from Lotioncrafter* for the small batch, but used my Braun stick blender for larger batches.
4. Cool to 40˚C and add the cool down phase with high shear mixing.
Don't forget to always test and adjust the pH. In the case of this formula, the pH was around 7. (I say around 7 at this point as my pH meter wasn't working, so I had to rely on pH strips.)
When I fixed up my meter and bought a new one, it registered pH 6.89 in a 10% solution in distilled water. It has to get down to 4.5 to 5 to actually be a conditioner, so I started adding drops of a 50/50 solution of citric acid and distilled water.
To make this, measure out 50% distilled water and add 50% citric acid. Store it in a plastic bottle of some sort. Mine has a disc cap so I can add it drop by drop to a product.
Into the entire container - 390 grams now - I added 0.04 grams citric acid, mixed, and it measured pH 4.84. Success! Considering I already had 0.3% in the heated water phase, this means that I only needed 0.01% more to bring it down to the pH level I wanted. That's not much, but it made such a difference!
ICE Restore cold process conditioner, I do miss the humectants I'd normally find in Incroquat BTMS-50.
Weirdly, I took very few pictures of this formula as I was making and bottling it. It's all gone now - it's the second from the left bottle - because I liked it so much!
What will I do differently next time? I think I'll add a few of my favourite ingredients, like proteins, and a bit more silicone. Join me on Monday as we take a look at that formula! Oh, and I think I'll make a version with some lovely Monoi de Tahiti (infused coconut oil), too.
