Decontamination procedures for skin exposed to phenolic substances

Area of Science:

• Toxicology
• Dermatology
• Emergency Medicine

Background:

• Skin contamination by hazardous chemicals like phenol, cumene hydroperoxide, and their byproducts poses significant health risks.
• Investigating effective decontamination methods is crucial for mitigating chemical exposure injuries.

Purpose of the Study:

• To evaluate the efficacy of polyethylene glycol 300/industrial methylated spirits (PEG-300/IMS) mixture as a decontaminant for skin exposure to specific chemicals.
• To assess the safety of PEG-300/IMS, particularly regarding eye irritation.

Main Methods:

• Rats were used to test the decontamination effectiveness of PEG-300/IMS (2:1 by volume) against phenol, cumene hydroperoxide, and phenol/acetone cleavage product.
• The mixture's efficacy was compared to water.
• Skin-damaging potentials of sodium hydroxide and sulfuric acid were also investigated.
• Eye irritation tests were performed on the PEG-300/IMS mixture.

Main Results:

• PEG-300/IMS (2:1) significantly reduced mortality, systemic effects, and skin burns from exposure to phenol, cumene hydroperoxide, and phenol/acetone cleavage product.
• In rats, the PEG-300/IMS mixture was found to be slightly less effective than water for decontamination.
• The PEG-300/IMS mixture did not cause eye irritation.

Conclusions:

• PEG-300/IMS (2:1) is a promising decontaminant for specific chemical skin exposures, reducing severe health outcomes.
• While water may be marginally more effective for decontamination in certain models, PEG-300/IMS offers a safe alternative, especially considering its non-irritating nature to the eyes.
