Suppliers & SDS

Trade Name vs INCI on a Supplier SDS

Why the marketing name on a supplier SDS is not the INCI you file, and how to bridge the two correctly.

Pull up an SDS for something like "EcoSurf CA-100" or "Crodafos CES" and you'll notice the big bold header at the top is a brand name, not an ingredient name. That header is exactly what a lot of makers copy straight onto their formula sheet, and it's exactly what a cosmetic filing system can't do anything with. Trade names are the supplier's product identity. INCI names are the universal ingredient language regulators actually work in, and getting from one to the other is a step that has to happen every single time, not just for exotic ingredients.

Why the SDS header isn't the answer

A safety data sheet has 16 standardized sections, and section 3, composition and information on ingredients, is where the real identity lives. That's where you'll find the actual chemical or INCI names of what's inside the trade-named product, sometimes alongside CAS numbers, sometimes as a percentage range if the supplier is protecting a proprietary blend.

The trade name at the top of the SDS is doing the same job a brand name does on a shampoo bottle, it's memorable and marketable, but it tells a regulator nothing about composition. "Crodafos CES" doesn't map to anything on a hotlist or a prohibited substances list. The INCI name it represents does.

Where this gets genuinely tricky

Two things make this harder than just reading section 3 once:

Blends hide behind a single trade name. A lot of surfactant and emulsifier products sold under one trade name are actually a mixture of two or three INCI ingredients. If the trade name product is used at 3% in your formula, and section 3 says it's 60% Ingredient A and 40% Ingredient B, your actual filing needs those two components at 1.8% and 1.2% respectively, not the trade name at 3%. Skipping this step is one of the most common ways an ingredient deck ends up wrong without anyone noticing.

CAS numbers don't always line up cleanly. Some ingredients carry more than one valid CAS number depending on the exact form or grade. Some botanical extracts have no CAS number at all, since they're complex natural mixtures rather than a single defined substance. Don't assume a mismatch between what you expect and what's on the SDS means an error, it might just mean the ingredient falls into one of these edge cases, and it's worth confirming with the supplier rather than guessing.

A practical mapping table

What you have What you actually need Where to find it
Trade name from a product label or SDS header INCI name(s) SDS section 3, composition
Trade name blend used at X% in your formula Each component's real percentage in the finished product Multiply component % (from SDS) by X%
CAS number confusion (multiple numbers or none listed) Confirmation from supplier on which applies, or acceptance that none exists for a botanical extract Direct supplier inquiry
No SDS provided at all A request to the supplier, since a legitimate raw material supplier should have one Supplier technical or regulatory contact

A short walkthrough

Say your formula sheet lists "Emulsifier X-200 at 4%." You pull the SDS, and section 3 shows it's actually Cetearyl Alcohol at 70% and Polysorbate 60 at 30%. Your real filing lines become Cetearyl Alcohol at 2.8% and Polysorbate 60 at 1.2% of your finished product, calculated from that 4% use level. The trade name never appears on the notification at all. If you'd filed "Emulsifier X-200" as a single line item, that's not something a regulator's ingredient system recognizes, and it would come back as an error or, worse, get accepted incorrectly and cause problems on amendment or audit later.

Building the habit

Every time you bring in a new raw material, before it goes anywhere near your formula sheet, pull the SDS, find section 3, and write down the actual INCI names and percentages next to the trade name for your own records. That five-minute habit at intake saves hours of reverse-engineering later when you're trying to file.

This exact translation work, trade name to INCI, expanding blends into real components, and carrying percentages through correctly, is the most tedious and error-prone part of preparing a filing by hand. It's also the core of what Cosmetic Comply automates: feed it your formula and supplier documentation, and it maps everything to INCI names and CAS numbers, expands blends into their true components, and flags anything it can't confidently resolve so a human reviewer can chase down the supplier before the notification goes out.
