Yunnan Baiyao sold toothpaste on a secret no competitor could know

Every toothpaste maker fights the same losing battle for a claim that sounds distinctive: whitening, natural ingredients, herbal extracts, a celebrity dentist's endorsement — all of it copyable within a product cycle, because any competitor can read the ingredient list and formulate something similar. A premium claim that a rival can reverse-engineer is a premium claim with an expiration date.

Yunnan Baiyao already held a claim no competitor could touch for a completely different reason: its founding wound-powder formula had been surrendered to the state in 1955 and classified a permanent national secret, one of only two traditional medicine formulas ever given that status — legally undisclosable, not merely undisclosed.

Used its state-sealed wound-powder formula in toothpaste, making the legally undisclosable secret itself the premium claim no rival could replicate.

The formula's state-secret status made it legally undisclosable, so rivals couldn't reverse-engineer it.

Applying that mystique to toothpaste gave the product a moat independent of R&D or marketing.

Rivals couldn't compete on the same axis, forcing them to price compete, while Yunnan Baiyao charged double.

The extension worked because wound care plausibly bridges to oral care through shared healing logic.

If you hold a legally protected asset, extend it to adjacent categories where its exclusivity makes a claim rivals can't legally make.

Yunnan Baiyao toothpaste reached the number-two spot in China's toothpaste market by 2016 and number one by 2019, holding roughly a quarter of the market by value through the early 2020s while priced at about double Colgate. The health-products segment built around it generated on the order of ¥6.5 billion (about $900 million) in 2023–2024 revenue, helping carry the parent company from a fading state pharmaceutical maker to a market capitalization Forbes put around $13 billion.
