What are the effects of prolonged exposure to sunscreen lotion on polyethylene?

Prolonged exposure to sunscreen lotion can significantly impact polyethylene, a common plastic used in packaging and consumer products. Sunscreen ingredients, such as organic UV filters and emulsifiers, may interact with polyethylene, leading to material degradation over time. Studies suggest that chemical components like oxybenzone and octinoxate can weaken polyethylene's structural integrity, causing brittleness or discoloration. Additionally, prolonged contact may alter the plastic's permeability, potentially affecting its durability and performance. Understanding these effects is crucial for industries relying on polyethylene for long-term applications, as sunscreen residues could accelerate wear and reduce product lifespan. Further research is needed to quantify the extent of these interactions and develop mitigation strategies.
