What material is used in CELESTA water bottles and why was it chosen?

CELESTA water bottles are produced using only Tritan™ Copolyester raw material.Tritan is a plastic that is as clear as glass, impact-resistant, lightweight, and highly resistant to heat.Its most important feature is that it is a material that isharmless to human health, non-toxic, and approved by authorities such as theFDA (U.S. Food and Drug Administration) and EFSA (European Food Safety Authority).

In our production, materialscontaining Bisphenol-A (BPA) such as polycarbonateare absolutely not used.Not only BPA, but also no member of the Bisphenol family such as BPS, BPFis included in our production processes.As CELESTA, we consider protecting user health to the highest level as a fundamental responsibility.

What does "BPA-free" mean? Why is it so important?

BPA (Bisphenol A) is a chemical that has been used for many years in the production of many plastic products, but has been banned in many countries due to its negative health effects. It can disrupt hormone balance, weaken the immune system, and pose serious risks, especially for children in their developmental stages.

In CELESTA products, not only BPA but also all other Bisphenol derivatives such asBPS (Bisphenol S)andBPF (Bisphenol F)are absolutely not present. This takes our products beyond the "BPA-free" label, offering acompletely chemical-free drinking experience. CELESTA users can safely use our products without risking their health.

Do you use paint on CELESTA products? How is the coloring achieved?

No, CELESTA products do not use paint in the traditional sense. Paints are usually applied to the surface later and can cause problems such as dissolution and peeling over time, which pose both aesthetic and health risks.

CELESTA products are colored withpigmentation technology. With this method, color pigments are directly combined with the raw material of the product and embedded into the product. This means the color is not on the surface but in the product's own structure. This method is both permanent and healthy because it eliminates the risks of paint dissolving.

Is the pigmentation method harmful to health?

Absolutely not. The pigmentation method ensures that coloring is donedirectly in the raw materialinstead of with chemical paint. The pigments used with this technique aresuitable for food contact, non-toxic, and compliant with international norms.

This way, CELESTA bottles produced with pigmentation are both aesthetically rich and completely safe for health. Issues such as fading, paint peeling, or separation of the colored layer do not occur.

How are your two-color (gradient transition) bottles produced?

CELESTA two-color bottles are produced withspecial double injection technology. With this technique, two separate pigments are mixed in a controlled manner to create a soft color transition, or a gradient effect, on the body.

This not only provides visual richness but also, when combined with pigmentation, becomes a healthy and chemical-free solution. No paint, varnish, or coating is applied. CELESTA's two-color bottles stand out with both their aesthetic and health-friendly structure.

Which chemicals are absolutely not used in CELESTA products?

No chemicals that could harm human health are used in CELESTA production processes. Not only Bisphenol A (BPA), but alsoBisphenol S (BPS),Bisphenol F (BPF), and all otherBisphenol derivativesare completely kept out of production.

Furthermore, our products do not contain components such asphthalates, heavy metals, aromatic amines, formaldehyde, PVC, or toxicplasticizers. All raw materials and pigments used aresuitable for direct food contactand have been tested according to EU norms. Maximum safety policy has been followed, especially considering the use by babies, children, and pregnant individuals.
