  • Boiling Point: 248 °F at 760 mmHg (decomposes) (USCG, 1999) Source: CAMEO Chemicals
  • Physical Description: Zinc phenolsulfonate appears as a colorless to white crystalline solid which turns pink on exposure to air. The primary is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. It is soluble in water. It is used as an insecticide and in medicine. Source: CAMEO Chemicals

  • ECHA C&L Notifications Summary: Aggregated GHS information provided per 77 reports by companies from 5 notifications to the ECHA C&L Inventory. Each notification may be associated with multiple companies.; Reported as not meeting GHS hazard criteria per 36 of 77 reports by companies.; There are 4 notifications provided by 41 of 77 reports by companies with hazard statement code(s).; Information may vary between notifications depending on impurities, additives, and other factors. The percentage value in parenthesis indicates the notified classification ratio from companies that provide hazard codes. Only hazard codes with percentage values above 10% are shown.

  • Health Effects: Chronic exposure to zinc causes anemia, atazia, lethargy, and decreases the level of good cholesterol in the body. It is also believed to cause pancreatic and reproductive damage. (L49) Source: Toxin and Toxin Target Database (T3DB)
  • Cosmetic Ingredient Review Finding(s): Safe in the present practices of use and concentration. Ingredient, concentration, and use information are available in documents discoverable at https://cir-reports.cir-safety.org Source: Cosmetic Ingredient Review (CIR)
  • Toxicity Summary: Anaemia results from the excessive absorption of zinc suppressing copper and iron absorption, most likely through competitive binding of intestinal mucosal cells. Unbalanced levels of copper and zinc binding to Cu,Zn-superoxide dismutase has been linked to amyotrophic lateral sclerosis (ALS). Stomach acid dissolves metallic zinc to give corrosive zinc chloride, which can cause damage to the stomach lining. Metal fume fever is thought to be an immune response to inhaled zinc.

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 “Zinc 4-hydroxybenzene sulphonate” 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 substance is not unrestricted: cosmetic use is subject to the conditions in the cited official record. Check product type, body area, concentration, purity and warning requirements before deciding whether a formulation is compliant.

If this row does not reproduce conditions, open the cited official detail because omission does not mean unrestricted use. No list match is not permission; Gulf/SFDA product, claim, notification and technical requirements still apply.

The record cites SFDA restricted list, page 3, row 2, 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.
