Today’s rather fun Fizzy Foaming Face Scrub comes from a recipe request Kaylee sent in. She’d found a facial scrub that fizzed up like a bath bomb when it got wet, as well as lathered up into a lovely foaming scrub that left your skin feeling wonderfully clean and exfoliated. The ingredients were simple enough, and I loved the idea of some fizz with my facial scrubbing, so here we are—Foaming Fizzy Facial Scrub!
The fizzy part comes from a combination of baking soda (with a basic pH) and citric acid (with an acidic pH). When the two get wet, you’ve basically got a mini version of that elementary school science baking soda/vinegar volcano happening in your palm (with the added benefit of it not smelling like vinegar).
Since this is a powdery project, we’ll be making it in our DIY-only coffee grinder (don’t try to make your kitchen one do double-duty; get one that’s just for DIY projects!). And since we’ll be whipping up a bunch of fine powders that will float around whenever the lid of the grinder is removed, we’ll also need our dust masks for safety—trust me, you don’t want to inhale any citric acid or SCI! The citric acid burns if it gets into your nasal passages, and if you can imagine what snorting a line of soap would feel like… well, that’s what inhaling SCI is like. Erk! Wear that dust mask, do your best Darth Vader impression, and enjoy not being plagued with some sudsy, burning sneezes as you work. Once the scrub is done it’ll be weighed down with the essential oils we’ll add, so you don’t need to worry about a dust mask for that part, but you definitely need one for the making phase.
As with most powdery projects, this one is delightfully easy to pull together once you have all the ingredients. We’ll be mixing it up in two parts, but the gist of it is: simply pop everything into your coffee grinder, put the lid on, and blend away. Rest, stir, blend some more, and that’s about it! I’ve got a video how-to with tips and what not, though depending on the volume of your coffee grinder you may find the plastic wrap tip isn’t terribly helpful here as it may reduce the volume of your grinder too much.
The final product is SO FREAKING COOL. Seriously, guys. It gets all fluffy and foamy and fizzy when it gets wet and you may find yourself just poking the growing foam monster in your palm for a minute or two instead of actually washing your face. When you finally do get around to washing up with it you’ll notice some mild exfoliation, a super delicious juicy, clean scent, and a chilly minty finish from them menthol. It’s da bomb, seriously. Your skin will feel oh-so-clean and smooth afterwards, and you’ll probably have to go grab your husband or roomie or something to make them ooooh and aaaah over your magically fizz-bubbly facial wash. Make it! You’ll love it 😄
Fizzy Foaming Face Scrub
Measure the arrowroot starch and essential oils into your DIY-only coffee grinder and blend everything together until the mixture is uniform. Let it rest for about three minutes before popping the lid off your coffee grinder (you won’t need a mask at this point as the starch will be well weighed down with the essential oils). Scrape the starch mixture into a small bowl.
Put on your dust mask. Measure the baking soda, SCI, citric acid, and menthol crystal into the coffee grinder and blend for about twenty seconds. Stop, whack the lid a few times with the back of a spoon to knock the powder back down into the grinding dish, and let the mixture rest for about three minutes. After three minutes have passed, remove the lid, give the contents of the grinder a stir with a small spoon (be sure to dig down to the bottom and turn the powder over), and repeat.
Once the baking soda mixture is uniform, add the starch/essential oil mixture, and pulse/stir to combine. Be sure to leave your dust mask on for all of this—inhaling citric acid, menthol powder, or SCI is unpleasant enough when it’s just one, let alone all three! You’ll need to pulse and stir your grinder as the mixture will be prone to clumping up; if your grinder starts sounding like it’s having trouble, stop and stir.
When that mixture is uniform, you’re done! Transfer it to a jar (120mL/4oz is a good size) for storage and use.
To use, sprinkle about 1/4–1/2 tsp into your palm, and add a wee bit of water. Delight in the fizzy, foamy goodness, and use that to wash your face. Less water will make for a more exfoliating scrub, more will make for a less exfoliating scrub.
Because this scrub does not contain any water, it does not require a broad-spectrum preservative (broad spectrum preservatives ward off microbial growth, and microbes require water to live—no water, no microbes!). Be sure to keep it dry to ensure it lasts as long as possible—don’t let any water get into the container and it should easily last a year.
If you don’t have red mandarin essential oil, try clementine essential oil, tangerine essential oil, or even orange essential oil. If you don’t have SCI, SLSa (Sodium Lauryl Sulfoacetate) will also work.
