If a product has more than one hazardous ingredient in it, do you list all ingredients on the SDS or the ingredient with the largest quantity?

According to Appendix D to 1910.1200, the SDS must include the chemical name and concentration (exact percentage) or concentration ranges of all ingredients which are classified as health hazards in accordance with paragraph (d) of 1910.1200 and:

1. Are present above their cut-off/concentration limits; or
2. Present a health risk below the cut-off/concentration limits.

(1) Are present above their cut-off/concentration limits; or (2) Present a health risk below the cut-off/concentration limits. (b) The concentration (exact percentage) shall be specified unless a trade secret claim is made in accordance with paragraph (i) of 1910.1200, when there is batch-to-batch variability in the production of a mixture, or for a group of substantially similar mixtures (See A.0.5.1.2) with similar chemical composition. In these cases, concentration ranges may be used.
