Procedure

1
Pre-dissolve HA powder in water to make a 1% solution (ideally 24h ahead).
2
Weigh Phase A (water, glycerin, HA solution). Sprinkle xanthan gum while stirring to hydrate.
3
Weigh Phase C (Olivem 1000, CCT, jojoba oil) in a separate beaker.
4
Heat both Phase A and Phase C to 75C in a water bath.
5
Pour Phase C into Phase A. Blend with a stick blender for 3 - 5 minutes until emulsified.
6
Allow to cool to below 40C, stirring occasionally.
7
Add Phase D (panthenol, Vitamin E, preservative). Mix well.
8
Check pH is between 5.3 - 5.8. Adjust if needed.
9
Pour into sterilized containers. Label and date.

Tips & Notes

•Target pH: 5.3 - 5.8.
•This is an emulsion-you must heat and blend the oil and water phases.
•HA solution should be pre-made: dissolve 1g HA powder in 99g water, let it hydrate fully.
•Use a digital thermometer to ensure both phases reach 75C before combining.
•Stick blender creates a smoother, more stable emulsion than hand stirring.
