@chemicalmatt Thank you for your help! I’ll check those ingredients out.

Thank you! @ngarayeva001

Thank you so much @Perry for all your input!

Thank you for your reply @Perry! Yes, that makes a lot of sense. 

I guess what I want to know is if those two preservatives I listed above will be effective in a pH range of 4-6. I read that the preservatives are suitable in a pH of up to 12. 

I know one cannot really tell if a preservative will be effective until a microbial test is conducted, but I would like to know if it will just be a waste of time trying to include it in this pH range.

Please, any more broad spectrum preservative suggestions will be appreciated!

@zetein Thank you so much for your reply, but I’d still rather not use parabens. That’s interesting about ethylhexylglycerin, thanks for letting me know! 

[Sasse]

Thank you all for your replies, I have gained a better understanding now! 

[Sasse]

Wow, thank you so much for the information! I was not sure if doing that would be considered incorrect or not. Now I know! 

[Sasse]

Thank you all so much for taking the time to comment! I’ve learned a lot. 

I will just go ahead and find extracts that are preserved with some of the ingredients in my main preservative so I won’t have to list extra preservatives. I think this will be the best option.

Thank you all for the comments, and sorry for the late reply. 

@alchemist01 I might just have to let go of the CETAC and up my Honeyquat levels as suggested. I’m not familiar with how to increase pH, only how to lower. 

@LincsChemist I am using 5% Btms and 3% stearyl alcohol.

Hello alchemist01, thanks for replying!

The most recent one I formulated was a 3.45. I thought it was a bit low.

I am also using Optiphen plus as a preservative at 1%

Thank you all!

Thank you ngarayeva001 and alchemist01 for commenting! 

With your suggestions, will it be possible to use .5% FO total in a formulation?
