  Scalp serum (O/W emulsion) FAIL! PLEASE HELP!

  Posted by arastellar09 on January 16, 2025 at 5:54 am

  Phase A:

  Distilled water (80%)

  Herbal extract (5%) {extracted by 70% ethanol}

  Phase B:

  Wanult oil (1%)

  Rose geranium E.O. (0.6%)

  Tocopherol mixed (0.4%)

  Symbiosolv Clear + (5%)

  Phase C:

  Sodium Ascorbyl phosphate (2%)

  Niacinamide B3 (1.2%)

  Pyridoxin HCl B6 (0.3%)

  D Biotin B7 (0.5%)

  Phase D:

  Clear Xanthan gum (0.5%)

  Acacia gum (0.5%)

  Propanediol (2%)

  Preservative:

  Optiphen + (1%)

  PROCEDURE:

  1) Mix Phase A and Phase B thoroughly in two separate breakers, then combine to make the O/W emulsion.

  2) Check the pH of the emulsion, should be around 6-6.5 for the vitamins to be effective. Add Phase C and stir. Check and adjust pH again to around 6.5.

  3) Mix all the ingredients of Phase D together and gently add it to the emulsion to thicken it.

  4) Later, add the preservative.

  PROBLEM:

  1) After few days for keeping the emulsion undisturbed, I can notice the oil droplets floating on the surface of the emulsion.

  2) There is a darker slimy thing settled at the bottom of the beaker. I don’t know what it is?

  Can anyone help? what went wrong?
