of no more perfume retained in formula even in 1% & very important

after a weak.Pls help me to solve this query.

If I wan to make preservative free cream with colostrum then what herbal ingredients should be added in my formula.

Sounds like your formula isn’t preserved properly. “Herbal” ingredients are not going to be enough to preserve your product. Colostrum powder (“bug food”) will be challenge to preserve. I would reduce your % of it drastically.There are some preservatives you can use and still call your product “preservative free” - have a look at Glyceryl Caprylate/Dermosoft GMCY, p-Anisic Acid/Dermosoft® 688 eco and naticide which are reviewed here - http://makingskincare.com/preservatives/Do bear in mind that if you are going to have any hope of the above preservatives working, that there’s a lot more to preservation than just adding a preservative eg reducing water activity, using packaging which minimises contamination in use, microbiological testing of raw ingredients and process water, etc and adding 0.1% disodium EDTA (heated water phase) and glycols will help. Another major factor is the amount of “bug food” in the formula - this often gives overlooked. I see many people putting goat’s milk, honey, hydrosols, floral waters, aloe vera, extracts, protein, powders, starches etc in their formulas which will really challenge the preservative system. For more info on this see the link above.

Thanks for your valuable response.I will definitely go through that sight.
I would also like to share you that I have dropped the colostrum % from 5 to 3 but still there was same problem, the formulation turns yellow with unpleasant smell after three four days. I am already using EDTA for chelating agent. -
Keep dropping the powder levels. 0.10% is a good starting point, and then try 0.01% if that doesn’t work.
Why are you using so much? Are you under the impression that colostrum powder actually has any effect on skin?
