Appearance test on C of A

Many of our products are tested to published specifications such as but not limited to ACS, FCC, EP, JP, USP, or NF. In many of these cases, appearance may not be a specification for meeting the particular grade, thus we do not add an appearance test to our analytical methods. Appearance testing may also be subjective and not commonly indicative of product performance. If you need general appearance information, it may be found in section 9 of our MSDSs. If you have a question about a particular product please contact us.
