How to Make a Moisturising Slime Hand Wash for Halloween

The aim of this hand wash is to make a thick slime-like green hand-wash. Perfect to put out for guests to use in your bathroom for a Halloween party, so note that is it purposely made to these quantities to create a thick slime-like body wash.  

Though remember to get it assessed and have ingredient label on the back of the bottle if other might use it.

I’ve kept the ration of SCI to CAPB, more on the CAPB side, as this produces a nice thick texture whilst giving you the option to have a transparent handwash if you use Xanthan Gum clear too.

I’ve paired cherry fragrance oil with the preservative eco, as preservative eco gives off an almond like scent, so this makes the finished product smell like Cherry Bakewell, despite being green and slime looking for Halloween 😉

Note that fragrance oils can affect the stability of hand/body wash formulations by changing the viscosity or in extreme cases, causing the mixture the separate.  I would recommend testing your chosen fragrance oil in a small batch, and if the recipe amount here of 1.5% thins or splits your mixture, try a lesser amount.  It's also worth noting that fragrances containing vanillin can discolour formulations.  You can of course make this recipe without fragrance or if you would like a subtle fragrance, then replace some or all of the water with a floral hydrolat like rose water instead.

To stabilise the formula you will likely need to adjust the ph to the lower end of the desired range.

Formula – 200g Batch

Phase A

30% (60g) Cocamidopropyl Betaine (CAPB) – Surfactant, emulsifier, foam boaster and thickener.

8% (16g) SCI Powder – Gentle surfactant and emulsifier

Phase B

50% (100g) Distilled Water – Solvent and base

7% (14g) Vegetable Glycerine - Humectant

1% (2g) Xanthan Gum (if you want a clear final result, use Xanthan gum clear - though this will depend on the surfactant blend and ASF) - Thickener

0.5% (up to 1g) Mica, Water soluble dye or Neon Pigment - Colour

Phase C

1.5% (3g) Cherry Fragrance Oil – Scent to pair with the preservative eco for a bakewell tart fragrance.

1% (2g) Saccharide Isomerate Plus – An intensely moisturizing, plant derived ingredient that locks in moisture from the product and the atmosphere for an instant and long-lasting effect. It can also boost foaming properties.

1% (2g) Preservative Eco – Broad Spectrum Preservative which also has an almond scent, which will add to our overall fragrance.

Method:

· Mix together the SCI and Cocamidopropyl Betaine in a heat proof beaker and put to one side.

· In a new Beaker, mix the Xanthan Gum and mica/dye/pigment into the vegetable glycerine until fully incorporated and then mix in your water.

· Heat phases A and B in water batch (a pan with about 1-2 inches of water) until the SCI has melted and both phases are around the same temperature.

· Take off the heat and pour Phase B into Phase A and mix well by hand, be careful not to create too many bubbles. It will be super thick at this point.

· Allow to cool to 40 degrees C and then you can add your Phase C ingredients and mix well again by hand. Since the mixture is super thick, you won’t be able to avoid creating some bubbles when mixing these in, but don’t worry they settle again over time.

· pH should be fine due to the ingredients used, but we need a pH no higher than 6.5 for the Saccharide Isomerate plus to be active, and I’d prefer a pH of around 5 for a handwash anyway, it’s best to check. You can dilute some product in water and use a pH strip if that is all you have. However, if you have a pH meter that can test the pH of creams and lotions, then use that for a more accurate reading. Ours came out at 5.44 which is perfect. I have linked the pH meter that I use in the video description.

Note that on sitting for 3 days some splitting occurred. Adjusting the ph to 4.5 (still in range for Saccharide isomerate plus) resolved this completely. 

· Pour into your container and it’s ready to use.

Notes:

· The idea of this handwash is obviously to be super thick and slime-like for Halloween, but if you want to make a thinner version for everyday use, you can reduce the Xanthan gum to 0.5%.

· If you don’t want a transparent version (ours wasn’t in the end as we only had Xanthan gum soft), then you can also alter the SCI and CAPB percentages to your liking. It’s the active surfactant matter that changes the product to be clear or opaque. I’ll be talking about this another time.

· Also, worth noting that some fragrance oils and essential oils can thin out mixtures, so you may need to adjust for this depending on which one you use.

· This is a great little recipe for your Halloween bathroom, as it not only looks like slime, but it smells amazing and leaves you hands feeling so soft!
