Tools & Equipment Needed
0.1g / 0.01g digital weighing scales
Glass beakers
Bain-marie/double-boiler
Spatula
A thermometer
pH strip / pH meter
Foamer Bottle
Ingredients
- 69.3 g distilled/filtered water | 69.3%
- 15 g Rose Hydrosol | 15%
- 10 g glycerin | 10%
- 1 g Silk Peptide | 1%
- 1 g Caprylyl/Capryl Glucoside | 1%
- 2.5 g Cocamidopropyl Betaine | 2.5%
- 0.2 g geranium essential oil | 0.2%
- 1 g Preservative | 1%
Instructions
- Blend the glycerin and hydrolyzed silk in a glass beaker.
- In another beaker, weigh out distilled water and hydrosol
- Blend surfactants in another beaker
- Add water-hydrosol mixture to glycerin & hydrolyzed silk
- Slowly blend the surfactants into the water-glycerin, but be very careful to avoid creating foam.
- Because the essential oil needed is a very low amount, you will need to use an accurate scale—preferably one accurate to 0.01g.
- Add the essential oil and stir well.
- Check that the pH using a pH strip or pH meter, check that the cream has a pH range that is compatible with your chosen preservative. This range is normally indicated by the supplier of the preservative. If your pH is not in a suitable range, you can lower it by adding an acid or raise it by adding sodium hydroxide or sodium bicarbonate.
- Finally, blend in the preservative
- Transfer it into a foamer bottle and label the finished product.
Notes
- Because this foam wash contains water, you MUST include a broad-spectrum preservative to ward off microbial growth. In the event, you notice any change in colour, scent, or texture, chuck it out and make a fresh batch.
- A formula should be written in a percentage of ingredients as well as grams. Our popular formulation calculator can be used to convert from percentages to weight easily. It also gives you warning alert if any of the category ingredients are out of recommended range to make sure the ratios between the ingredients are as desired.
- You can use a different hydrosol instead of the rose, or you can also use more distilled water instead of a hydrosol.
- Caprylyl/Capryl Glucoside combines well with other glucosides to make a complete foaming shower gel so you can replace Cocamidopropyl Betaine with Coco-Glucoside or Decyl Glucoside. Alternatively, you can Coco-Glucoside in place of Caprylyl/Capryl Glucoside, however, in this case, you will need a solubilizer to ensure the essential oils solubilize. You can choose a natural solubilizer, Symbio®Solv Clear Plus. Polysorbate 20, which is also a good alternative as it very easy to work and forgiving ingredients. However, because it is PEG-derivative, so it is not considered “natural” cosmetics.
- You can always use a different essential oil blend as you wish but make sure you find the optimum EO: solubilizer ratio.
Buy it from an online DIY ingredient supplier or Amazon.
