I've been wanting to make a foaming foot scrub for a while now, but formulating a good recipe has actually been quite the challenge.
What is in a Scrub?
Typical DIY scrubs are made with oils, butters and sugar or salt for the exfoliation. You'd think making a foaming version would be a simple matter of adding in a surfactant, but it wasn't quite that easy. Because of the high oil content, my earlier formulations overwhelmed the surfactant and it ended up separating and not foaming at all. Not ideal! I had to lower the oil content considerably and find other ways to make up the bulk of the scrub.
We end up with a scrub made with the surfactants SCI and cocamidopropyl betaine for foaming and cleaning action, some stearic acid to help bulk it out and firm it up, and I included some lactic acid to help exfoliate and soften feet. Jojoba beads make up the physical exfoliant and a little mica and essential oil make it fun! We whip it up to make it soft and fluffy. The end result has a gentle cleansing, bubbly exfoliating action. It will be sure to please and even makes a great gift!

And yes you can add lactic acid to creams :)
Hi Melanie, I haven’t tried this recipe with Geogard Ultra, but you can certainly give it a go. Geogard Ultra is water soluble so add it to that water in the cool down phase. You’ll just need to check the pH as Geogard Ultra works in a pH range of 3-7, so make sure the pH is compatible.
Hi Juliette, if I already have Geogard Ultra to use as preservative, can I replace the Euxyl PE9010 with that? Also, can the lactic acid be included in facial creams, e.g. the anti-aging face cream recipe?
Kind regards
Melanie
