Ultraviolet light can seriously degrade the quality and consistency of personal-care products packaged in PET bottles and containers that are not properly protected. Cosmetics, perfumes, lotions and liquid hand soaps are among the products at risk.
Product exposure to sunlight and artificial light sources at any point in its life cycle potentially can cause colours to fade and shift, fragrances and aromas to go “off,” and chemical formulations and ingredients to lose their potency.
Milliken’s ClearShield Colourless UV Absorber tackles this problem head-on. In addition to protecting UV-sensitive packed contents from degradation, this technology also maintains the clarity and transparency of PET, and does so in a novel, efficient way.
It incorporates the UV absorber into the PET package itself, allowing brand owners to remove the often-high loadings of traditional UV additives they previously had to include in the formulations of the packaged contents.
This also helps to address consumer demands for “natural” ingredients by enabling the use of more highly UV-sensitive natural essences, fragrances and colorants in the packaged products. Click here for more information.
ClearShield 390B stands out because it integrates directly into the PET, which testing has shown does not migrate out of the plastic and contaminate the product, while preserving PET’s crystal clarity.
ClearShield’s UV absorber filters 95% of UV light at up to 390 nanometers and is effective at very low loadings. So, an added benefit is that formulators can reduce additive costs since they can obtain the same protection while using up to 10 times less UV ClearShield absorber than traditional absorbers.
ClearShield is also a very sustainable choice. Not only are clear containers favoured by recyclers, but adding ClearShield to PET packaging reduces waste-water contamination caused by some of the chemicals traditionally used in other UV stabilisers.
Packaging is a key differentiator for personal-care goods and can make your products stand out on store shelves. But the value of appealing packaging vanishes quickly if the package fails to properly protect the contents.
Product consistency – in appearance, fragrance, colour and ingredient potency – is vital to brand integrity.
Deliver your products to consumers in clear, transparent packaging while protecting the quality and consistency of those PET-packaged contents by using Milliken’s ClearShield Colourless UV Absorber. It’s a clear choice.
