  Hi All,

  Seeking help and advise on a stability issue we are facing in making a AHA/BHA facial serum.
  The formulation:

  Glycolic acid - 3%

  Lactic acid - 5%

  Citric acid - 1%

  Salicylic acid - 0.35%

  Tranzamic acid - 3%

  Aristoflex silk - 0.4%

  Aristoflex HMB - 0.4%

  IPM - 0.1%

  Dimethicone 200 - 6 cst - 4%

  Glycerin - 2.5%

  Propanediol - 2%

  Butylene glycol - 2%

  pentalene glycol - 2%

  Veriver essential oil 0.2%

  This formulation separated in 4wks at 45oC.

  Im seeking your advise on how best to stabilise it so it passes the 12 wk stability test at 45oC, 49C and RT.

  Grateful for your help and advise.

  Regards,

  M
