A glass bottle is often considered better for cosmetic products for several reasons:
Protection against contamination Glass is a non-porous material that provides a strong barrier against external contaminants such as bacteria, mold, and chemicals. This helps preserve the integrity of the product and extend its lifespan.
Preserving product quality: Unlike plastic, glass does not chemically interact with cosmetic ingredients. Therefore, there is no risk of chemicals transferring from the container to the product, which could alter its quality, stability, or effectiveness.
Heat stability Glass is more heat-resistant than plastic, making it ideal for cosmetic products that might be exposed to high temperatures during storage or transport. This reduces the risk of the container deforming or leaking.
Light protection Some cosmetic products, especially those containing light-sensitive ingredients, can degrade when exposed to sunlight or other light sources. The opaque or tinted glass used in glass bottles provides additional protection against harmful UV rays, thus preserving the stability and effectiveness of the products.
Sustainability Glass is a robust and durable material that withstands temperature changes and physical shocks well. Glass bottles are less likely to warp or deform over time, ensuring a long shelf life for the cosmetic products they contain.
Ecological Glass is 100% recyclable and can be recycled indefinitely without losing its quality. This makes it a more environmentally friendly choice compared to plastic, which is less recyclable and can cause environmental problems when disposed of.
In summary, a glass bottle offers better protection, better preservation of product quality, stability in the face of heat, favorable optical properties and a more ecological option compared to plastic containers for cosmetic products.
