toxicity
Acute oral toxicity
According to the toxicity of animal fatty acid components, it is non-toxic.Acute oral administration of C to test ratssixteenAnd CeighteenLD from acidfiftyThe amount of is more than 10 g/kg body weight.In addition, LD obtained by acute oral administration of octadecenoic acid and octadecadienoic acid to test ratsfiftyThe amount of is more than 21.5ml/kg body weight.
Skin protection
Animal fatty acids should not be irritating to the skin and should not be produced according to the safety studyskin sensibility。After repeated skin contact test on human body, hexadecanoic acid, octadecanoic acid and octadecadienoic acid will not cause skin irritation basically.It will not cause skin allergy.
Eye protection
According to the safety study, animal fatty acids may cause slight temporary irritation to the eyes

·Environmental prevention: discharge, surface and underground water shall be minimized.
·Spill removal procedure: neutralization is not required.Includes spills.Absorb or cover with dry soil, sand or other incombustible materials and move to a container for disposal.according toUS Federal GovernmentAnd/or local government requirements as grease orOily materialshandle.
Protective measures
·Personal prevention: good labor hygiene habits should be followed.
Avoid breathing (heated) steam.Avoid eye and skin contact.
·Exposure limit value: not determined.
·Exposure control:
Process control: ventilation: on-site discharge – recommended
Mechanical – if working on
Personal protective equipment:
Eyes - goggles or gogglesProtective mask, determined by the site exposure.
Skin – Protective gloves: rubber or plastic.
Depending on the site exposure, additional personal protective equipment such as boots and full protective clothing may be required.
Inhalation – Not required at ambient temperature, although suitable NIOSH/MSHA approvedAir purifying respirator。If the concentration exceeds the processing capacity of the cartridge respirator, the NIOSH/MSHA approved independentOxygen respiratorOr air purifying respirator.Note: The air purifying respirator cannot protect workers in oxygen deficient environment.
