This luxurious lemon meringue whipped soap takes inspiration from one of my favourite desserts—lemon meringue pie. With its bright lemony scent, faint yellow hue, and decadent whipped texture, it’s lovely in a wee dish by your sink for hand washing and impressing guests.

Because this whipped soap is stabilized with stearic acid, it has a wonderfully lightweight, airy texture. Glycerin is added to lubricate the mixture enough to whip—I tried to whip this up without adding as much glycerin, and ended up with something that resembled oily cottage cheese curds. It was a distinctly less luxurious looking soap 😉

Those little white beads are the stearic acid.

I chose buriti oil to give this soap its slight yellow tint, but I know it can be tricky to find. You can use sea buckthorn seed oil or a natural orange or yellow dye instead, or just leave the soap as is and call it the meringue part of the pie instead. Additionally, if you don’t have lemon and orange essential oils, and citrus essential oil you happen to have will contribute a nice, bright citrussy scent and will work in a pinch.

I’ve rounded the whole thing out with a touch of silk peptides for an added luxurious feel, and some kaolin clay to give the soap enough slip to comfortably shave with.

Now we're talking whippy!

The final soap is soft, airy, and pretty darn fun to use, especially if you’re used to bars and pump-top bottles. I’m in love!

Lemon Meringue Whipped Soap

100g | 3.5oz cream soap paste
100g | 3.5oz just-boiled water

40g | 1.41oz stearic acid

6 tbsp vegetable glycerin

½ tsp silk peptides, powder, or amino acids
2 tsp kaolin clay
20 drops buriti oil (or other bright orange carrier oil)
20 drops lemon essential oil
12 drops orange essential oil

Combine the cream soap paste and just-boiled water in a smallish (~500mL/2 cup) leftover container with a sealing lid. Mash them together a bit, seal, and leave the paste to absorb the water for at least 9 hours—overnight works like a treat.

Move the soap paste to a glass or metal mixing bowl and add the stearic acid. Set the mixing bowl over a pan of simmering water to melt the stearic acid. Be extra, extra certain all the stearic acid has melted, or you’ll end up with tiny little beads of it in your soap, which is less than ideal.

Once everything has melted, remove the bowl from the heat and start whipping it with your electric beaters to combine everything. It will look lumpy and gross, and that’s ok. Add the vegetable glycerin, one tablespoon at a time, whipping between additions. Once you get all the glycerin in, it’ll finally start to whip up.

Whip away until you’re happy with the texture, and then whip in the silk, clay, buriti oil, and essential oils. Lightly spoon into a wide-mouthed jar and enjoy!

I got this great little jar from Stepback in Vancouver—follow them on Instagram!
