Genstore Partners with Double White for Private Label Teeth Whitening Strips

Los Angeles - September 11, 2025 - Genstore [www.genstore.ai], a leading e-commerce platform, has announced a strategic partnership with Double White, a teeth whitening manufacturer based in Guangzhou, China. This collaboration aims to provide private label teeth whitening strip solutions for Genstore's growing portfolio of e-commerce brands.

Double White, established in 2003, has built a reputation for supplying high-quality teeth whitening products to e-commerce businesses, distributors, wholesalers, and other B2B buyers. The company offers a range of private label and customized whitening products, including teeth whitening strips, gels, and pens. According to the press release, Double White supports e-commerce brands with product selection, formula options, samples, private labeling, OEM/ODM development, packaging coordination, bulk manufacturing, and repeat-order supply.

For e-commerce businesses entering the teeth whitening category, Double White emphasizes the importance of more than just competitive unit prices. The company highlights that product format, formula, packaging, private labeling, inventory planning, and repeat-order stability can all influence the long-term performance of a whitening strip SKU. Double White supplies multiple teeth whitening strip formats for brands targeting different markets and consumer positions.

Genstore's partnership with Double White is part of its strategy to expand its offerings in the oral care segment. The company sees significant growth potential in this market, with the global teeth whitening market expected to reach a value of approximately $12.5 billion in 2024. During the period from 2025 to 2034, the market is expected to grow at a CAGR of 6.5%, culminating in an estimated market value of $22 billion by 2034.

Double White offers a range of teeth whitening strip formats, including hydrogen peroxide, PAP, sodium chlorite, and other customized concepts. E-commerce brands can choose from various formula options, considering factors such as target country, sales platform, consumer profile, product positioning, intended whitening active, treatment duration, and packaging format. The company also supports the development of private label products, including brand logo, custom pouch artwork, retail box design, formula direction, flavor selection, strip shape and dimensions, treatments per box, instructions, multilingual labels, product inserts, and carton specifications.

Packaging is a crucial aspect of e-commerce requirements. Double White advises that packaging should balance several priorities, including visual presentation, shipping efficiency, product protection, clear instructions, and market-specific information. The company offers a structured private label development process, from defining the target market to arranging shipping and inventory delivery.

Genstore and Double White plan to launch a focused SKU strategy, starting with a standard private label whitening strip and expanding based on consumer demand. The initial product will be a clear test of market interest, with subsequent products potentially offering different formulas, residue profiles, flavors, or strip structures. Premium packaging, additional treatments per box, and complementary products can be introduced later to build a broader oral care portfolio.

Both companies emphasize the importance of sample confirmation before bulk production. Factors such as strip fit, adhesion, flavor, gel consistency, removal experience, packaging appearance, and overall consumer usability are carefully evaluated. The final approved sample and specification will serve as a reference for production.

Double White supports e-commerce brands with a range of services, including product selection, formula options, samples, private labeling, OEM/ODM development, packaging coordination, bulk manufacturing, and repeat-order supply. The company encourages buyers to provide detailed project information, such as target country, sales platform, preferred whitening strip type, formula preference, treatments per box, packaging requirements, estimated initial order, expected replenishment needs, and target launch date.

This partnership between Genstore and Double White marks a significant step in Genstore's expansion into the teeth whitening market, leveraging Double White's expertise to meet the growing demand for high-quality, private label oral care products.
