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

[Priya]

Hello all, I am formulating cream with 5%, 7%., 10% colostrum powder. But my formulation is not stable. colostrum has its own type odour cause of no more perfume retained in formula even in 1% & very important query is that the formulation turns to yellow with unpleasant smell after a weak.

Pls help me to solve this query.
