Citric acid as preservative?

I picked up some from the health food store to use as a preservative for FSG. How much should i wisk in at the end of making fsg (8 oz)? I have read too much can dry out your hair.

Thanks!

I was told to use 1/4 tsp. for one cup of FSG. It didn't work for me, my gel was molded the next morning.

Is citric acid not for adjusting the ph value? I use grapefruit seed extract for preservative.

Yes, it is used to adjust pH.

If you need a preservative, you need to use a product that is actually a preservative. There are no natural ones--not a single one. I make toiletries and I used to work in microbiology. Whoever makes a natural preservative is going to be one very, very rich person/corporation.

GSE won't work--or maybe I should say, it does work but not in the way most people think. Manufacturers of GSE were putting preservatives--parabens or benzethonium chloride in their product. That's what had the antimicrobial activity; not the GSE itself.

If you want to use a preservative in a product, you're going to have to do a little chemistry work or you can contact someone who sells preservatives, tell them what you made and ask for a suggestion on how to preserve it.

For instance, silver citrate + potassium sorbate + citric acid as ph adjuster. I am not a microbiologist so I would like to know. I had considered using this combo for my natural products. Could the combo be considered a natural preservative? TIA for your help.

Can you use food contain citric acid? Like lemon? Just wondering..

citric acid is not a preservative.
Oh thanks, I'm new to this.

I've been thinking of making homemade things like lip balm and scrubs, but I don't want to wake up one day and it stinky and covered with mold. Any cheap and easily found in stores ideas?
