Plastic bottles, especially disposable water and soda bottles, are not designed for long-term use. Most of them are made of PET (polyethylene terephthalate), a material that is safe for single-use packaging but may release harmful substances if reused or exposed to unsuitable conditions.

When plastic bottles are repeatedly refilled or used to store liquids like vinegar or oil, their chemical stability is compromised, turning an originally safe container into a health hazard.

PET bottles are intended for cold beverages. But when used improperly, they may release toxins. For instance, research shows that PET bottles filled with vinegar (acidic liquid) release significantly higher levels of antimony, a toxic heavy metal used in the manufacturing process.

This means a harmless-looking plastic bottle could become a source of contamination, affecting your daily health.

Two factors make plastic bottles particularly unsafe:

• Heat: PET cannot withstand high temperatures above 70°C. When used to store hot water, hot food, or placed near a stove, harmful substances leach out much faster.
• Time: Plastic degrades with age. Bottled water expiration dates are not only for the beverage itself, but also for the container. Old, brittle bottles leach more chemicals, posing long-term health risks.

• Antimony (Sb): Used in PET production. Chronic exposure can damage skin, liver, kidneys, and heart.
• Phthalates (plasticizers): Added to improve flexibility, but they disrupt hormones and increase cancer risk.

These substances accumulate in the body over time, making daily exposure dangerous even if short-term effects seem invisible.

Not all plastics are equal:

• PP (#5, Polypropylene): Microwave-safe, commonly used in food containers and baby bottles.
• HDPE (#2, High-Density Polyethylene): Stronger and safer than PET, often used for milk bottles.
• Glass and stainless steel: 100% reusable, chemical-free, and the best long-term option.

But the most sustainable solution is not just "switching materials"-it's eliminating single-use bottles altogether.
