Winning Candy Grapes Whipped Foot Scrub

Updated: Nov 29, 2020

After some pain in the ass technical (but important and useful though) first two blogs on Accessible skincare science, we're continuing a bit more creatively!

I was super excited last month to participate in Formula Botanica's formulation challenge. The challenge was to create a whipped foot scrub and include ingredients that are in season in our local area.

This was the first challenge that I didn't miss since I started my studies, so you can get the idea of how excited I was (actually it felt a bit like winning the lottery).

And guess what?!? I WON!!! (not the lottery though)

The challenge was a lot tougher than I thought. Picking an ingredient that is in season (with all the gorgeous fruits, nuts, herbs, and flowers around me) was like owning only one pair of shoes - for a lady.

But I made it. I made this worth calling a challenge. With all the knowledge and experiences that I gained during my studies, this was a lovely reminder of how going from KISS ("keep it super simple") to advanced formulations may sometimes be easier than going from advanced to KISS. This was super fun, valuable, and challenging back to basics work.

My 3 main goals before I started to write my formulation were:

  • max. 10 ingredients

  • 1 seasonal star ingredient

  • easy wash-off (I really, really don't like greasy products on my body, especially not on my feet or hands).

The final scrub was exactly as I wanted.

Fluffy, heavenly smelling, washed off nicely, leaving the feet smooth and nourished.

Now enough with the babble, let's get to the formulation procedure, shall we? Here is my Candy Grapes Whipped Foot Scrub inspired by sour candy frozen grapes.

Firstly, I melted my mango butter and glyceryl stearate along with my grapeseed oil until completely dissolved over a bain-marie. I added glyceryl stearate since it is known for reducing the greasiness of high-oil products. I then placed the blend in the fridge to cool below 40°C.

Meanwhile, the blend was cooling down, I had the time to prepare my phase B ingredients. I powdered my grape leaves (using my coffee grinder) and added ground grape seeds, white sugar, and SCI (Sodium cocoyl isethionate). SCI, also known as "baby foam" is a sodium salt ester of coconut fatty acid. It is an extremely gentle anionic surfactant that offers very efficient cleansing and low odor with a skin-friendly pH.

SCI makes the scrub wash off easily (5% still leaves a nice nourished skin feel, but I would go up to 10% if I wanted a matt wash-off).

IMPORTANT: Please don't forget to wear a dust mask while working with SCI! Inhaling powdered SCI is extremely unpleasant and could be dangerous (apparently, protective masks are not hard to find these days #w*f).

Once the oil phase had cooled down in the fridge, I added my phase C ingredients (preservative, antioxidant, and essential oil) and stirred well then put back in the fridge until it started to solidify.

I then whipped the mixture at high speed with an electric whisk until it changed the color to a lighter shade and gained volume. Afterward, I added phase B ingredients and placed it back in the fridge for a few minutes.

Lastly, I gave it a final whip until light and fluffy.

Don't worry if the scrub is going to look pretty pale at this stage, the green color will become more obvious when the scrub stabilizes to room temperature.

  • glass bowl

  • glass beaker

  • electric whisk

  • spatula

  • spoon

  • disinfectant

  • empty container

  • scale

  • dust mask




32% mango butter*

32% grapeseed oil

2% glyceryl stearate


20% white sugar

5% SCI - Sodium cocoyl isethionate (powdered)

5% grape seeds (ground)

2% grape leaves (powdered)


1% Preservative Eco

0.7% lime essential oil

0.3% rosemary co2 extract

*I used refined mango butter in this formulation since this is a wash-off product. This way, the wonderful lime aroma is even more exquisite.


Melt phase A in a water bath. Place the blend in the fridge to cool. Mix phase B. Add the phase C ingredients to the cooled phase A. Put back to the fridge until it starts to solidify. Whip on high speed with an electric whisk, then add phase B and place back in the fridge for a few minutes. Whip again until light and fluffy. Store and label.



Don't get stuck on grapes! (although I love it) Feel free to change the theme of this formulation to cranberries, watermelon, walnuts, coffee, lavender, or anything you think may work great as a foot scrub. Have fun and be creative!

I would be thrilled to see you make this. Make sure to tag @labnotes_eu on IG and use #madewithlabnotes.


Someone might be interested in sour candy frozen grapes formula (no % this time): squeeze some lime juice over the grapes. Roll each grape in sugar, until completely coated and store in the freezer.

If you don't have glyceryl stearate you can leave it out of the formula and increase the oil and butter ratio for that 2% (use 33% of mango butter and 33% of grapeseed oil). The scrub will have a slightly different (but still lovely) texture. It will still have a nice wash-off due to SCI. If you live in a warmer climate you could try and use cetyl alcohol instead of glyceryl stearate to give the scrub some firmness, but you will have to try and adjust the ratios if needed. Hope that helps! Enjoy, Ana


Is there any substitute for glyceryl stearate?
