  • Environmental Bioconcentration: Since 1,3-propane sultone hydrolyzes rapidly in water(1,2), bioconcentration in aquatic organisms is not expected to be a significant process(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: If 1,3-propane sultone is released to soil, it will be expected to rapidly hydrolyze if the soil is moist, based upon the rapid hydrolysis observed in aqueous solution(1,2,SRC). Since it rapidly hydrolyzes, adsorption to and volatilization from moist soil are not expected to be significant processes, although no data specifically regarding the fate of 1,3-propane sultone in soil were located(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: If 1,3-propane sultone is released to water, it will be expected to rapidly hydrolyze, based upon a measured rate constant of 8.2X10-2 hr-1 for hydrolysis in aqueous solution at 25 °C(1) which corresponds to a half-life of 8.5 hr(SRC). The product of hydrolysis is 3-hydroxy-1-propanesulphonic acid(2). Since it rapidly hydrolyzes, bioconcentration, volatilization, and adsorption to sediment and suspended solids are not expected to be significant processes((SRC). No data were located concerning biodegradation, but 1,3-propane sultone will probably abiotically hydrolyze significantly faster than biodegradation(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: ATMOSPHERIC FATE: If 1,3-propane sultone is released to the atmosphere, it will be susceptible to photooxidation via vapor phase reaction with photochemically produced hydroxyl radicals. An atmospheric half-life of 8 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm has been calculated for this process based upon an estimated rate constant(1,SRC).

Every page and entry in the public SFDA prohibited and restricted ingredient indexes; restricted detail pages remain the source for conditions.

Verification checklist

  1. Search names and CAS across both SFDA lists.
  2. Open the cited restricted-entry detail and apply every condition.
  3. Check current SFDA/GSO technical regulations and updates.
  4. Complete eCosma notification, label and responsible-party requirements.

Verification workflow and record completeness

Before using this result in a compliance decision

  1. Confirm that “1,3-Propanesultone” and every CAS/EC identifier refer to the material in your supplier specification.
  2. Search names and CAS across both SFDA lists.
  3. Open the cited restricted-entry detail and apply every condition.
  4. Check current SFDA/GSO technical regulations and updates.
  5. Complete eCosma notification, label and responsible-party requirements.
  6. Document the source version and recheck the regulator before manufacture, notification or market placement.

Questions this page answers

This official record identifies the substance as prohibited for cosmetic use in the stated market scope. Do not rely on a formulation containing this identity until the cited source, effective date and exact substance match have been verified.

A prohibition entry may contain no separate condition text because the regulatory outcome is the prohibition itself. No list match is not permission; Gulf/SFDA product, claim, notification and technical requirements still apply.

The record cites SFDA prohibited list, page 75, row 9, source version live-snapshot-2026-08-30. Open the official source.

No. CAS helps resolve identity, but jurisdictions can classify the same substance differently and can apply different product scopes, limits, warnings and transition dates.
