There are a number of reasons why cosmetic manufacturing companies might want to find a replacement for a raw material that is being currently used.
One of the reasons can be because the ingredient can no longer be sourced, or simply because the product is no longer steady, or does not suit the marketing desirability of certain products containing the ingredients that need to be changed.

The following are the production principles that manufacturers follow when switching over to better replacement alternatives:
1. Decipher & comprehend what role each ingredient plays
If a formulator accedes to formula as many cosmetic specialists do, there are probably ingredients included for which one is not sure about its functions. One needs to comprehend this before making the change to something new.
2. Seek possible & alternative replacements
Once the complete impact of the ingredient becomes known on the replacement formula then one can find possible substitutes. The smart thing would be to get feedback from the suppliers for their preferred replacements.
3. Test the prototype as a pre-production step
As was seen above as regards the making of prototypes what needs to be done now is to thoroughly test the prototype, to prove the market feasibility of the product as in if they perform as expected and if they meet the parameters to satisfy the product utility & test to know how it performs under certain conditions and if it does, then how well does it do so.
Thus more often than never the manufacturer will invest in seeking alternate substitute ingredients either to save cost or enhance the marketing of the products so as by improving the formulas.
