None of the 13 markets tracked here holds an imported rule under the name BUTYLENE GLYCOL.

That is a statement about this inventory, not about the law: no imported rule is not evidence that a substance is permitted. A rule may exist under a different name, under a CAS or EC number this glossary entry does not carry, or in a dataset not yet imported.

  • 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: IDENTIFICATION AND USE: 1,3-Butanediol is an odorless, colorless, viscous liquid with a sweet flavor and bitter aftertaste. It is used as an intermediate in manufacture of polyester plasticizers; humectant for cellophane, tobacco; and in the cosmetic and pharmaceutical industry as a glycerin substitute.1,3-Butanediol also has some mold inhibiting action. It is not registered for current pesticide use in the U.S., but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses. HUMAN EXPOSURE AND TOXICITY: 1,3-Butanediol is not irritating to human skin or mucous membranes. When applied to the human eye it causes immediate severe stinging, but irrigation with water brings rapid complete relief. ANIMAL STUDIES: Eye irritation occurred in one individual, although its irritant potency in rabbits appeared low. It was of low acute oral toxicity to rodents. No treatment-related effects on mortality, body weight gain, organ weights, hematology, histopathology or neoplastic changes were observed in rats fed 1,3-butanediol in the diet at 1, 3 or 10% (~ 643, 1960 or 6230 mg/kg-bw/day for males or ~ 844, 2330 or 7300 Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: An estimated BCF of 3 was calculated in fish for 1,3-butanediol(SRC), using an estimated log Kow of -0.29(1) and a regression-derived equation(1). According to a classification scheme(2), 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), an estimated Koc value of 1(SRC), determined from a structure estimation method(2), indicates that 1,3-butanediol is expected to have very high mobility in soil(SRC). Volatilization of 1,3-butanediol from moist soil surfaces is not expected(SRC) given an estimated Henry's Law constant of 2.4X10-9 atm-cu m/mole(SRC), based upon its vapor pressure, 0.02 mm Hg(3), and assigned value for water solubility, 1X10+6 mg/L (miscible)(4). 1,3-Butanediol is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(3). 1,3-Butanediol is expected to be readily biodegraded based on modified Sturm test results of 80.5% in 28 days(5). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1(SRC), determined from a structure estimation method(2), indicates that 1,3-butanediol 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 2.4X10-9 atm-cu m/mole(SRC), derived from its vapor pressure, 0.02 mm Hg(4), and assigned value for water solubility, 1X10+6 mg/L (miscible)(5). 1,3-Butanediol is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3). According to a classification scheme(6), an estimated BCF of 3(SRC), from an estimated log Kow of -0.29(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). 1,3-Butanediol is expected to be readily biodegraded based on modified Sturm test results of 80.5% in 28 days(7). 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), 1,3-butanediol, which has a vapor pressure of 0.02 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1,3-butanediol 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 12 hours(SRC), calculated from its rate constant of 3.32X10-11 cu cm/molecule-sec at 25 °C(3). 1,3-Butanediol does not contain chromophores that absorb at wavelengths >290 nm(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).
