Directions
1. Weigh the SLES, CAPB, Glycerine, Fragrance Oil and Optiphen Plus and Whisk to combine.
2. Add the distilled water and gently stir to combine.
3. Add liquid color.
Gently stir to combine. Cover the mixture and leave it to dissolve. Once the mixture is uniform, you’re done!
5. Package the handwash in a bottle with a foamer top; the foamer top is a must. Use as you’d use any hand wash. Enjoy!
Recipe Note
Before packaging, we’ll quickly test the pH to ensure it’s correct. Create a 10% dilution by weighing 2g product and 18g distilled water into a small bowl or beaker and whisk to combine. The pH should come out to right around 4.75, which is great—no need to adjust. (Please read this article to learn more about pH adjusting.)
SHELF LIFE & STORAGE
Because this foaming hand wash contains water, you must include a broad-spectrum preservative to ward off microbial growth. This is non-optional. Even with a preservative, this project may eventually spoil as our kitchens are not sterile laboratories, so in the event you notice any change in colour, scent, or texture, chuck it out and make a fresh batch.
