The Nexus Between Synthetic Leather and Human Health

The Nexus Between Synthetic Leather and Human Health . Synthetic leather, also known as faux leather, is widely used in furniture, clothing, automotive interiors, and more. It is favored for its relatively low cost, durability, and resemblance to natural leather in appearance and feel. However, some synthetic leathers can pose health risks during production and use. Understanding these risks helps us make healthier choices.

Components of Synthetic Leather and Potential Health Risks

  1. Polyvinyl Chloride (PVC) Synthetic Leather:
    • Components and Manufacturing Process: PVC is one of the most common materials for synthetic leather. It is typically made flexible and durable through the addition of plasticizers and stabilizers.
    • Health Risks: Plasticizers like phthalates are endocrine disruptors that can affect hormonal balance. Some stabilizers contain heavy metals like lead and cadmium, which can cause heavy metal poisoning with prolonged exposure.
  2. Polyurethane (PU) Synthetic Leather:
    • Components and Manufacturing Process: PU leather is made from polyurethane resin, known for its good flexibility and wear resistance. It is generally considered more eco-friendly than PVC.
    • Health Risks: Some low-quality PU leather may use toxic solvents in production, leading to the release of volatile organic compounds (VOCs) harmful to the respiratory system.
  3. Other Chemical Additives:
    • Preservatives and Flame Retardants: To extend product life and enhance safety, synthetic leather often contains preservatives and flame retardants. If these chemicals do not meet environmental standards, they can cause potential health hazards such as skin allergies and respiratory issues.

How to Choose Eco-Friendly Synthetic Leather for human health

When selecting synthetic leather products, consumers can ensure health and environmental safety by considering the following factors:

  1. Look for Certification Marks:
    • Choose synthetic leather products with environmental certification marks like the EU’s REACH certification or OEKO-TEX Standard 100. These marks indicate that the product complies with strict environmental and health standards.
  2. Understand Product Ingredients:
    • Opt for products with clearly labeled ingredients that do not contain harmful chemicals such as phthalates and heavy metals. Prioritize water-based polyurethane (water-based PU) or solvent-free polyurethane (solvent-free PU) leathers, which are more environmentally friendly and safer during production and use.
  3. Smell and Texture:
    • Before purchasing, smell the synthetic leather. Avoid products with a strong, unpleasant odor, as this may signal the presence of harmful chemicals. High-quality synthetic leather should feel soft and smooth without a greasy or uneven texture.
  4. Choose Reputable Brands:
    • Select products from reputable brands and manufacturers. These brands typically focus more on product quality and environmental standards, providing detailed product information and safety assurances.
  5. Follow Usage Instructions:
    • Adhere to the product’s usage and care instructions to avoid environments like high temperatures and open flames, which can reduce the release of harmful substances.


Synthetic leather is prevalent in daily life, but its potential health risks should not be overlooked. Consumers should prioritize eco-friendly and safe options by choosing certified products, understanding their composition, and avoiding those with strong odors. Supporting companies that improve production processes and reduce harmful chemical use is also our shared responsibility. Through collective effort, we can create a healthier and more sustainable living environment.
