STARCH, FOOD, MODIFIED: HYDROXYPROPYL DISTARCH PHOSPHATE
CAS 53124-00-8
EPA lists this substance on the non-confidential Toxic Substances Control Act Chemical Substance Inventory as Starch, hydrogen phosphate, 2-hydroxypropyl ether.
This is a TSCA industrial chemistry record, not a food or flavor assessment. Presence on the TSCA Inventory says a substance is in US commerce. It says nothing about whether it may be used in food, and this substance is not FEMA GRAS. For flavor ingredients see the FEMA GRAS lookup.
Commercial activity status
Active
EPA designates this substance active in US commerce, so no Notice of Activity Form B is required before manufacturing. What active and inactive mean.
EPA regulatory flags
EPA marks this listing with 2 flags. Each one is shown with EPA's own definition and what it obliges.
Indicates a polymeric substance containing no free-radical initiator in its Inventory name but is considered to cover the designated polymer made with any free-radical initiator regardless of the amount used.
What it obliges: Nothing directly. It widens what the listing covers, so a polymer made with a different initiator is still the listed substance rather than a new one.
Indicates a substance exempt from reporting under the Chemical Data Reporting Rule, (40 CFR 711).
What it obliges: Nothing, for this substance, in the CDR census. The exemption belongs to the chemical and not to your company, so every other substance you make above the reporting threshold still counts.
What it does not establish: Says nothing about hazard, about commercial activity status, or about obligations under any other part of TSCA.

What this page does not establish
It reports what EPA publishes about CAS 53124-00-8 in the July 2026 release of the non-confidential Inventory. It does not report the contents of any order or rule that a flag points at, because EPA does not publish those on the Inventory, and it does not say whether a particular use of yours is permitted.
It is also not a food or flavor clearance. This substance carries no FEMA GRAS number.
