  Preservative help.

  Posted by amitvedakar on October 10, 2025 at 5:37 am

  I am using parabens for preservative in cream containing White Petrolatum, Liquid Petrolatum, BHT, Glycerin, Propylene Glycole, fragrance, Cetosteryl alcohol, Cm1000 & vitamin E.

  I want to replace paraben preservatives with Ethylhexylglycerin & Phenoxyethanol (mix)

  SMP==0.2% & SPP-0.05%

  what % should i use of ETHYLHEXYlglycerin & PE2?

  @PhilGeis

  IS 0.7-0.8% ok?

  PE9010 as you know is 90% Phenoxy and 10% CG. (Listed right in the name. 😁 )

  Typical top end of the use rate is 1%….so you can do the math.

  PE 9010 is weak on YMF….so I would look to address this concern with an additional aide.

  Aloha.

    After re-reading my comment….I did not mean to imply….using 1%. With a minimal bug food formula like yours….if it were mine….I would use a total amount of .7 to .8%….plus a boost on YMF. Look at total picture…quality of water, packaging, pH…and mfg GMP.

    Since I use a repacker to source my 9010… I add a little more than possibly needed….to cover those aspects. 😅
