Since you wish to engage a third party for manufacturing of your natural and organic skin care products, you should consider the following
a) Contract Manufacturing agreement - This agreement contains very important clauses such as quantity to be delivered, quality, test reports, intellectual property , indemnity, liability, NDA etc. About 60 different parameters are covered under contract manufacturing agreement including raw materials,acceptable quality criteria , rejections etc.
b) Coming to Confidentiality, Non Disclosure and indemnity thereof- Though these are covered in general under Contract Manufacturing Agreement, it is always better to enter in to these specific agreement so as to cover the promoters, employees and contract workers of Third Party service providers so that your formulae is protected at all points of time.
Please note both the above agreements warrant that you consult a lawyer of your choice who can
a) Understand your product.
b) Understand your process
c) Take your inputs on what process/raw material/formulation which should be under your total control and what processes can be outsourced to third party manufacturer with protection of Contract manufacturing agreement, Confidentiality, Non Disclosure and Indemnity thereof.
