Weigh all stage 1 materials into a stainless steel bowl and place into a saucepan of boiling water (double boiler/bain marie). Bring up to a temperature of over 75°C.
When the stage 1 is over 75°C, add the boiling water to a larger stainless steel bowl. Swap the bowls over so the larger bowl is in the double boiler.
When both Stage 1 and Stage 2 are both over 75°C, pour the Stage 1 ingredients into the large bowl (stage 2) and stir gently without creating air bubbles. stir continually for 5 minutes maintaining the temperature over 75°C.
After 5 minutes, remove bowl from the double boiler and put into a pan of cold water to cool it down quickly. Keep stirring all the time.
When the cream or lotion is under 40°C add the remaining stage 3 ingredients. Combine thoroughly, jar and label.
