Butylene glycol + hexylene glycol to preserve water based products
I am finding a few brands use,
BG + HG to preserve face mist, specially Korean ones.
In some formulas they seem to use EHG.So basically,
Glycols + EHG seems to be their common preservation system.
BG+ HG + EHG for water based formulas
BG + Capryl glycol + EHG for emulsion based formulas.
Capryl Glycol + EHG is a standard combination from Sensiva.
But Schulke doesn’t give any MIC info but general use % 0.5-2%I am breaking my head to figure out % of BG + HG + EHG for water only products.
Can anyone help!I make water based gels and I find PE 9010 irritating in water based formulas. i think its the same with most other preservatives for water based formulas without any oils.
