Isodecyl acrylate: Does not have an individual approval but may be used as a component in a product covered by a group standard. It is not approved for use as a chemical in its own right.

May polymerize; A mild eye, nose, and throat irritant; [CAMEO] Repeated dose feeding studies of rats produced no significant adverse effects; [eChemPortal: HPVIS] Hazardous polymerization may occur; A skin irritant; [MSDSonline] See ACRYLIC RESINS (MONOMERS).

ISODECYL ACRYLATE is an acrylate ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Polymerizes readily in the presence of heat and light generating much heat; reacts with strong oxidants. REF [Handling Chemicals Safely, 1980. p. 235]. Reaction is not violent (USCG, 1999).

Isodecyl acrylate

Marine pollutant

The effectiveness of phenolic inhibitors is dependent on the presence of oxygen and the monomers must be stored under air rather than an inert atmosphere. Temp must be kept low to minimize formation of peroxides and other products. Moisture may cause rust-initiated polymerization. /Acrylic acid & derivatives/

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

Awareness of the dangers and of good engineering design are essential to safety. Employees should be instructed about the necessity of cleansing the skin if it is contaminated by materials which are irritants or skin-absorbed. With careful design, however, and complete enclosure of those processes where toxic chemicals or intermediates occur, dangerous exposures can be avoided. /Acrylic acid & derivatives/

/SIGNS AND SYMPTOMS/ Human signs and symptoms following ingestion of acrylic monomers include collapse, severe respiratory difficulties, and CNS stimulation. /Acrylates/

/SIGNS AND SYMPTOMS/ Allergic reactions have been reported for some acrylates. /Acrylates/

/LABORATORY ANIMALS: Acute Exposure/ Contact sensitivity was produced in guinea pigs with mono-, di-, and tri- acrylate compounds. /Mono-, di-, and tri- acrylate compounds/

/LABORATORY ANIMALS: Acute Exposure/ The acute toxicity of the acrylates decreases with increasing molecular weight. ...Acute inhalation of higher concentrations may cause /CNS depression/, salivation, and pronounced nasal, ocular, and pulmonary irritation or edema. Prolonged skin or eye contact may result in severe tissue damage. /Acrylates/

/LABORATORY ANIMALS: Subchronic or Prechronic Exposure/ The pathology from single exposure is not particularly characteristic, contrary to repeated exposure effects, which include pulmonary congestion or hemorrhage and cloudy swelling and organ weight changes of the liver and kidney, reported following subchronic exposures to excessive concentrations. /Acrylates/

/LABORATORY ANIMALS: Developmental or Reproductive Toxicity/ Animal studies using rats revealed that some acrylates and methacrylates are embryotoxic. The doses of monomers used in the animal studies, however, were much higher than concentrations likely encountered by workers. /Acrylates and Methacrylates/

/LABORATORY ANIMALS: Developmental or Reproductive Toxicity/ Monomers of 5 methacrylate esters and acrylic acid /including isodecyl acrylate,/ were administered at 3 dose levels to female rats on days, 5, 10, and 15 of gestation. The incidences of resorptions, dead fetuses, gross abnormalities and skeletal malformations were presented for each of these groups /and/ were smaller (P</=0.01) than those of the untreated controls.

Acrylates and methacrylates are detoxified predominantly via conjugation with glutathione via the Michael addition reaction or glutathione-S-transferase. They are also likely to be hydrolyzed via carboxylesterases. The lower molecular weight esters are rapidly metabolized and eliminated, therefore, will not likely cause cumulative toxicity. /Acrylates/
