In the beaker, weigh out then gently stir the surfactants together, trying to avoid making any bubbles.
20 g Decyl Glucoside, 16 g Cocamidopropyl Betaine, 10 g Lamesoft PO65 Surfactant
In the small container mix the glycerin and the xanthan gum until you have a smooth paste and the gum has fully dissolved. If you have a mini milk whisk, this is perfect for this job. Otherwise, stir well with a silicone spatula.
12.6 g Glycerine, 2.4 g Xanthan Gum
In a separate container add the water and hydrosol, followed by the panthenol. Stir until well combined.
20 g Lavender Hydrosol, 106 g Distilled Water, 4 g Liquid D-Panthenol
Pour the gum slurry into the water, and carefully stir. You will notice the water is becoming quite thick as the gum dissolves
Now it's time to add the slurry water to our surfactant. Do this slowly and stir carefully to keep the bubbles at a minimum.
Once combined, add the polyquat 7 to the mix, once again stirring.
6 g Polyquat 7
Finally, stir in the Lavender and mint Essential Oil followed by the preservative. You will notice the shampoo becoming thinner as you add these. This should become more stable once we have corrected the pH and allowed the gum in the shampoo to settle overnight.
0.5 g Lavender Essential Oil, 0.5 g Peppermint Essential Oil, 2 g Geogard ECT
As an optional step, you can add a little food coloring or liquid soap dye.
Using a pH strip test the pH of the finished shampoo. We are looking for a pH of around 4 to 5. If it isn't and it most likely will not be you will need to adjust it. See instructions on how to adjust the PH.
Transfer the shampoo to a suitable container and allow the shampoo to sit for 24 hours before using.
Notes:
Notes: Decyl Glucoside is hard to thicken, we always recommend thickening it with xanthan gum as other gums don't work well with it. I would suggest using coco glucoside instead if you wish to use an alternative gum.Any changes can alter the viscosity of the finished product. We suggest doing a smaller batch of around 50g as a trial, then adjust the gum if need be. How to adjust the PH of your product: First, test the pH of your product to see where the product currently sits. Then, you can bring the pH down with lactic acid. Simply add a couple of drops at a time checking as you go. Or you can make up a solution of 10% Citric acid to 90% distilled water. Which is 1g of citric acid dissolved in 9g of water. Once again add small amounts at a time and then test again, repeating until you reach a reasonable PH.
