"polypropylene glycol monobutyl ether", "synthetic lubricant"
Toxic to aquatic organisms, may cause long- term adverse effects in the aquatic
Although ingestion is not thought to produce harmful effects, the material may still be damaging to the health of the individual following ingestion, especially where pre- existing organ (e.g. liver, kidney) damage is evident. Present definitions of harmful or toxic substances are generally based on doses producing mortality (death) rather than those producing morbidity (disease, ill-health). Gastrointestinal tract discomfort may produce nausea and vomiting. In an occupational setting however, ingestion of insignificant quantities is not thought to be cause for concern. Considered an unlikely route of entry in commercial/industrial environments.
Although the material is not thought to be an irritant, direct contact with the eye may produce transient discomfort characterized by tearing or conjunctival redness (as with windburn). capable of causing a mild, temporary redness of the conjunctiva (similar to wind-burn), temporary impairment of vision and/ or other transient eye damage/ ulceration.
The material is not thought to produce adverse health effects or skin irritation following contact (as classified using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting. The material may cause skin irritation after prolonged or repeated exposure and may produce on contact skin redness, swelling, the production of vesicles, scaling and thickening of the skin.
The material is not thought to produce adverse health effects or irritation of the respiratory tract (as classified using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable control measures be used in an occupational setting. Not normally a hazard due to non-volatile nature of product.
There is some evidence that inhaling this product is more likely to cause a sensitization reaction in some persons compared to the general population.
Principal routes of exposure are by accidental skin and eye contact and by inhalation of vapors especially at higher temperatures. One ingredient of the product has caused skin sensitization reactions, shown as localized reddening and hives, or may produce respiratory sensitization characterized by asthma- like symptoms and runny nose. Contact allergy to antioxidants of the phenylamine type found in industrial greases has been reported. [Kalimo etal, Contact Dermatitis, 20, 151-152, 1989] A cohort study on cancer amongst workers exposed to anti-rust oil used in the bearing ring wrapping department has concluded that the causative agent was phenyl-alpha-naphthylamine or its N-nitroso-derivative. Jarvholm & Lavenius, Scand.J. Work, Environment & Health, 7, 179-184,1981] Rats showed increased lung cancer rates when injected with the technical grade substance. [Wang etal, Cancer Research 44, pp 3098-3100, 1984] As with any chemical product, contact with unprotected bare skin; inhalation of vapor, mist or dust in work place atmosphere; or ingestion in any form, should be avoided by observing good occupational work practice.
