I'm afraid you'll have to bear with me on this one.
Looking at producing an oil-wax based, pigmented mixture in a reasonably archaic facility. It's spreadable and with some emulsifiers for wash-off but ultimately should remain on skin for long periods in sweaty/wet conditions, but doesn't feature water in its ingredients. The shades this product can be produced in are reasonably specific.
All else aside, what sort of acceptance criteria would you suggest for the above product? The EU guidance stipulates that acceptance criteria must be tested in a laboratory, but doesn't stipulate what acceptance criteria should (or typically does) cover. Thanks in advance.
