Application:
Note:
Phase | %W/W | Raw Material | Function |
A | 75 | Deionised Water | Solvent / diluent |
0.5 | Aloe Powder 200x Strength | Moisturiser/skin repair | |
0.1 | Disodium EDTA | Chelating agent to help preservative work better | |
3 | Glycerin | Humectant | |
0.25 | Xanthan Gum | Thickener/ Emulsion Stabiliser | |
Heat phase A to 70-75°C. Mix until clear and until the xanthan gum is fully hydrated | |||
B | 12 | Camellia Refined Oil | Emollient |
0.5 | Beeswax | Emollient, thickener | |
3.4 | Shea Butter | Emollient | |
0.5 | Glyceryl Stearate Citrate | Emulsifier Secondary | |
3 | Emulsifying wax vegetable (Cetearyl Alcohol, Cetearyl Glucoside) | Emulsifier Primary | |
Heat Phase B to 70-75°C to melt ingredients. Turn off the heat and add phase B to phase A using an overhead mixer to stir continually until the two phases blend together and form a cream. Continue to mix on a medium speed until the temperature cools to 50°C or below. | |||
C | 1 | Plantaserv P (phenoxyethanol, Ethylhexylglycerin) | Preservative |
0.25 | Natural Vitamin E(tocopherol) | Antioxidant for product and skin protection. | |
0.25 | Perfume of choice | Aroma | |
Add ingredients from phase C into the mix with gentle stirring. Once all is combined move to a homogeniser and homogenise for 2-3 minutes to form a smoother cream | |||
D | qs | Citric Acid or Sodium Hydroxide solution to adjust pH to 3.8-4.5 | The ideal pH for this type of moisturiser is between 5.5-7. The preservative works across a broad range of pH and the skin naturally sits at 4.5-5.5. pH can be adjusted here if necessary. Usually an un-adjusted base like this will have a pH around 7 as that is the pH of water, the main ingredient influencing pH. The EDTA can make the product more alkali though while the aloe tends to reduce pH. |
Remove from the mixer and test the products pH using a calibrated pH meter. Adjust as necessary to pH 5.5-7 using citric acid to bring the pH down or Sodium Hydroxide to increase the pH. | |||
