HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity (Oral) Category 4 Warning H302: Harmful if swallowed P301+P312: IF SWALLOWED: Call a POISON CENTER or doctor/physician if you feel unwell.
P264: Wash ... thoroughly after handling.

P330: Rinse mouth.
P501: Dispose of contents/container to ...
It was set as Category 4 based on average LD50= 443.7 mg/kg. This average was calculated using the upper/lower limits of rat oral LD50 values = 250-500, 590, and 1300 mg/kg (Patty (5th, 2001) , and 950-1130 mg/kg (DFGOT (2001)). In addition, although compound is considered to be a mixture of isomers, ACGIH and DFG were estimated for isomer. From the description that "All toxicity studies are conducted by all hydroxypropylacrylate isomers, mainly 75% 2-hydroxy-1-propyl acrylate and 25% 1-hydroxy-2-propyl acrylate or 66% 2-hydroxy-1-propyl acrylate, 33% 1-hydroxy-2-propyl acrylate and 1% free acrylic acid" (DFGOT (2001)), it was assumed that each component indicated equal toxicity.
1 Acute toxicity (Dermal) Category 2 Danger H310: Fatal in contact with skin P302+P350: IF ON SKIN: Gently wash with plenty of soap and water.
P262: Do not get in eyes, on skin, or on clothing.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.

P310: Immediately call a POISON CENTER or doctor/physician.
P322: Specific treatment (see ... on this label).
P361: Remove/Take off immediately all contaminated clothing.
P363: Wash contaminated clothing before reuse.

P501: Dispose of contents/container to ...
It was set as Category 2 based on rabbits dermal LD50= 112 ul/kg (DFGOT (2001)) = 112 x specific gravity 1.06 = 119mg/kg. In addition, although test compound is considered to be a mixture of isomers, both ACGIH and DFG were evalated as a mixture. And the description that "toxicity studies have been performed by all hydroxypropylacrylate isomers, mainly 75% 2-hydroxy-1-propyl acrylate and 25% 1-hydroxy-2-propyl acrylate or 66% 2-hydroxy-1-propyl acrylate, 33% 1-hydroxy-2-propyl acrylate, and 1% free acrylic acid" (DFGOT (2001)), it was assumed that each component indicates equal toxicity.

Inflammation in the respiratory systems and localized pneumonia are seen by inhalation dosage of 0.053 mg/L for 30-day using a mouse, a dog, a rat and a rabbit. (DFGOT (2001)) Since the dose with effect was below the guidance value (0.2 mg/L) of Category 1, it was classified to Category 1.
