  • First Aid: EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.; SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.; INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Ap Source: CAMEO Chemicals

  • Environmental Bioconcentration: An estimated BCF value of 2 was calculated for C.I. Acid Blue 1(SRC), using a measured water solubility of 30,000 mg/l(1) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 15(SRC), determined from a measured water solubility(2) and a recommended regression-derived equation(3), indicates that C.I. Acid Blue 1 will have very high mobility in soil(SRC). Due to the ionic nature of C.I. Acid Blue 1, the retention of the dye by ion-exchange processes(4,SRC), particularly on clay surfaces, and adsorption at mineral surfaces such as geothite(5,SRC), may slow down or prevent leaching(SRC). As C.I. Acid Blue 1 is an ionic compound, volatilization of this compound will not be important from moist soil surfaces(4,SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 15(SRC), determined from a measured water solubility(2) and a recommended regression-derived equation(1), indicates that C.I. Acid Blue 1 should not adsorb to suspended solids and sediment in water(SRC). However, due to the ionic nature of C.I. Acid Blue 1, the retention of the dye by ion-exchange processes(3,SRC), particularly on clay surfaces, and adsorption at mineral surfaces such as geothite(4,SRC), may lead to increased adsorption on some surfaces(SRC). As C.I. Acid Blue 1 is an ionic compound, volatilization from water surfaces is not expected(3,SRC). According to a classification scheme(5), an estimated BCF value of 2(1,SRC), from a measured water solubility(2), suggests that bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: ATMOSPHERIC FATE: The ionic state of C.I. Acid Blue 1 makes this compound essentially non-volatile(1,SRC); therefore, this compound should exist in the particulate phase in the ambient atmosphere. Particulate-phase C.I. Acid Blue 1 may be physically removed from the air, mainly by wet deposition(SRC). Source: Hazardous Substances Data Bank (HSDB)

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. RDC 1.030/2026 amends rather than replaces the prohibited baseline, and the second restricted-list revision was still under consultation in July 2026.

The record cites RDC 529/2021 consolidated annex, entry 1355 (through RDC 1.030/2026), source version RDC 529/2021 consolidated through RDC 1.030/2026. 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.
