Source: Cosmetic Ingredient Review (CIR)
  • Cosmetic Ingredient Review Finding(s): Safe for use in cosmetics, with qualifications Source: Cosmetic Ingredient Review (CIR)
  • Toxicity Summary: IDENTIFICATION AND USE: Ethylparaben forms small colorless crystals, or white powder. Ethylparaben inhibits the growth of fungi and bacteria and is used as a preservative for pharmaceuticals, adhesives, and various cosmetic preparations. HUMAN EXPOSURE AND TOXICITY: Ethylparaben was a skin irritant in man. It gave no evidence of sensitizing potential in a human study. The paraben esters as a generic class are rare sensitizers when applied to the intact skin of man. Application to the damaged skin is a more common cause of sensitization. A methyl:ethyl:propylparaben mixture has been shown on oral administration to exacerbate pre-existing skin complaints. ANIMAL STUDIES: Ethylparaben was an eye irritant in rabbits. A low acute oral toxicity has been demonstrated for ethylparaben in laboratory animals. Limited long-term studies in rats have also indicated a low toxicity and have generated no evidence of carcinogenic activity. Ethylparaben in the diet produced cell proliferation in the forestomach of rats. No evidence of mutagenicity was reported in limited Ames Bacterial tests. Ethylparaben did increase chromosomal aberrations in a Chinese Hamster ovary cell assay, but similar effects Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: An estimated BCF of 20 was calculated for ethylparaben(SRC), using a log Kow of 2.47(1) and a regression derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), Koc values ranging from 119 to 209(2) indicate that ethylparaben is expected to have high to moderate mobility in soil(SRC). The pKa of ethylparaben is 8.34(3), indicating that this compound will partially exist in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of ethylparaben from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 4.8X10-9 atm-cu m/mole(SRC), using a fragment constant estimation method(5). Ethylparaben is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 9.3X10-5 mm Hg(SRC), determined from a fragment constant method(6). Half-lives of about 14 days and 3.5 days were measured in aerobic screening tests conducted with phenol- and cresol-acclimated sludge over 7 day and 1 day incubation periods(7,8), respectively, suggesting that biodegradation may be an important fate process in soil(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), Koc values ranging from 119 to 209(2), indicate that ethylparaben is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 4.8X10-9 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(5), an estimated BCF of 20(SRC), from its log Kow of 2.47(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Half-lives of about 14 days and 3.5 days were measured in aerobic screening tests conducted with phenol- and cresol-acclimated sludge over 7 day and 1 day incubation periods(8,9), respectively, suggesting that biodegradation may be an important fate process in water(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), ethylparaben, which has an estimated vapor pressure of 9.3X10-5 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase ethylparaben is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be one day(SRC), calculated from its rate constant of 1.3X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase ethylparaben may be removed from the air by wet and dry deposition(SRC). Ethylparaben contains chromophores that absorb at wavelengths >290 nm(4) and therefore may be susceptible to direct photolysis by sunlight(SRC). Source: Hazardous Substances Data Bank (HSDB)

Methylparaben

Methylparaben is a 4-hydroxybenzoate ester resulting from the formal condensation of the carboxy group of 4-hydroxybenzoic acid with methanol. It is the most frequently used antimicrobial preservative in cosmetics. It occurs naturally in several fruits, particularly in blueberries. It has a role as an antifungal agent, a neuroprotective agent, an antimicrobial food preservative and a plant metabolite. — ChEBI

Verification checklist

  1. Confirm INCI/CAS/EC identity.
  2. Review every current GB Annex II–VI match.
  3. Check commencement dates and later statutory instruments.
  4. Verify SCPN, responsible-person, safety-report and labelling duties.

Verification workflow and record completeness

Before using this result in a compliance decision

  1. Confirm that “4-Hydroxybenzoic acidmethylparabenpotassium ethylparabenpotassium parabensodium methylparabensodium ethylparabenethylparabensodium parabenpotassium methylparabencalcium paraben” and every CAS/EC identifier refer to the material in your supplier specification.
  2. Confirm INCI/CAS/EC identity.
  3. Review every current GB Annex II–VI match.
  4. Check commencement dates and later statutory instruments.
  5. Verify SCPN, responsible-person, safety-report and labelling duties.
  6. Document the source version and recheck the regulator before manufacture, notification or market placement.

Questions this page answers

This identity appears on a market positive list for the list function represented by the source record. Confirm that the intended function and product use fall within the list scope and every stated condition.

Positive-list presence is purpose-specific and is not blanket approval for every cosmetic use. No annex match is not approval and does not cover Northern Ireland, which follows the applicable EU framework.

The record cites GB Cosmetics Regulation, Annex V, entry 12, source version 2026-08-15. 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.
