    I’ve attached a pic, why I’m using two preservatives at the 1%. Looking at Euxyl K 940, this gives the guidance to mix both Euxyl PE 9010 and Euxyl K 900, and at 1% each both phenoxyethanol and benzyl alcohol are under their maximum usage rates. I could drop both preservatives down to 0.75%. This would be closer numbers to Euxyl K 940.
