The top whitening strip providers are trustworthy because of their excellent manufacturing standards and sophisticated formulations. A great example is Onuge, which produces over 100 million pieces every year and is based in Guangdong, China. ISO 22716- and GMP-certified, the factory has extensive experience in the manufacture of phthalimido-peroxy-caproic acid (PAP) and of alcohol-free whitening strips; it is a main supplier for those brands in search of strong yet gentle whitening. Onuge pays special attention to non-peroxide formulations, which appeals to most people with sensitive teeth, while the large production capacity meets high demand on various global markets.
The other major supplier is Crest under Procter & Gamble, also with a strong distribution network across North America. Its hydrogen peroxide-based strips, manufactured in FDA-compliant facilities, provide whitening up to three shades in just two weeks. Crest, on the other hand again, follows all the standards of the FDA and focuses on clinical research, and therefore, has wide consumer acceptance for faster and more intense whitening.
Hello Products provides several strips with activated charcoal and coconut oil, in which natural ingredients are concentrated. The products are cruelty-free and vegan-friendly, manufactured in FDA-regulated facilities. All Hello strips consist of recyclable material and have never been tested on animals, building the brand's credibility with environmentally sensitive consumers and the increasing desire for whitening safety and ethics.
White Glo is based in Australia, manufacturing in the EU; it supplies peroxide-free whitening strips that utilize activated charcoal. Because of their adherence to the standards regarding safety in the EU, their products are hypoallergenic, especially popular within the European consumer market that desires gentle yet effective whitening. White Glo's strict adherence to EU regulations has gained them a considerable market share in the European market for whitening strips.
Each of the suppliers-Onuge, Crest, Hello Products, and White Glo-has its respective merits to meet various consumer segments. Large-scale sensitive-friendly options from Onuge, clinically supported peroxide products from Crest, eco-sensitive formulae from Hello, and EU-compliant standards set White Glo apart to lead in the industry for whitening strips.
