Hello Kerry,
When using a preservative, how long would you suggest shelf life for? Is this a sellable product in your opinion?
Thankyou, Natasha -

Hi Natasha,
We do not have a cheat sheet as each preservative has a range, and that is just going to get confusing with multiple options. If you have Optiphen Plus the range is 0.75 – 1.5%. The easiest way would to be to choose the 1% mark so you add 1gm for each 100 grams of mask you make. This recipe makes 100gm so you will need 1gm of optiphen plus. -

Hi
I was wondering do you have a cheat sheet for the preservative percentage when needing to add it to items to prolong shelf life? I’m new and not the best at conversions, also can you use any preservative for the items or is it specific to each item made? As I only have optiphen plus I think it is from memory -

Each preservative will have a range listed – Euxyl PE 9010 lists 0.5-1.0% so in this case the mid point is the middle of these figures, so should be used at 0.75%, so 0.75gm per 100gm of face mask.
Hi Natasha,
I would think a year would be a reasonable time line. Please test well before selling, as with all items you are looking to sell.
