  Topical hair spray/presevative

  Posted by Viktor on January 19, 2022 at 2:50 pm

  Hello,

  I`d like to ask a question.

  Can anyone tell me if my hair spray formulation needs any preservative in your opinion

  100ml of spray:  25% Ethoxydiglycol

                             20 % Propylene glycol

  Thank you for your advice

  You need to list all of the ingredients.
  25% + 20% = 45%.  What is in the other 55% of your formula?

  Dear Perry,

  100ml of spray:  25% Ethoxydiglycol

  That is really low Aw, so if you use any preservative at all it wouldn’t need much. Dr. Phil?

  It’s a bit weird to sell hair spay with only these 3 ingredients.

  Let’s wait for Dr.Phil.

  Saw this one and agree - risk should be low.  Needs Aw measured and know that’s not av  or  accessed by most folks.  Would be real interesting to see effect of the two moderator ingredients.
