Ingredients Used at Levels Below Suppliers' Recommended Minimum %?
Do suppliers allow you to use their ingredients in formulations at levels that are below the suppliers' recommended minimum usage percentages for the given ingredient?
Any responses and discussion are greatly appreciated. Thanks!

Of course. You can use an ingredient at any level you like (except for OTC active ingredients).
Suppliers typically exaggerate the amount of an ingredient you need in a formula. There is no incentive for them to get you to use less & lots of incentive to get you to use more.
Plus, they don't really know. It's unlikely any supplier has down optimization work to figure out the bare minimum of an ingredient you need to get an effect.
Information from suppliers should be looked at as a general guideline, not hard fast rules.
