Every soap brand claims it's additive-free and nobody believes any of them, so the chairman bit into a bar on camera

the problem

A Chinese soap maker needed to prove its 'additive-free, food-grade' safety claim in a market where every competing brand makes the identical claim and consumers believe none of them

background

what everyone would do

The standard response to a distrusted, category-wide safety claim is more of the same low-cost evidence formats every competitor already uses — more certificates, more advertising copy, more third-party endorsements — none of which requires the claimant to personally risk or sacrifice anything to make.

what they saw

Qi Dexin's demonstration worked because it made the claim cost him something real and irreversible — actually eating the product — at exactly the moment every competing brand's identical assurance had become worthless through overuse. A claim that costs the claimant nothing to make is cheap to fake and cheap to ignore; a claim a company's own chairman is willing to physically act on in front of an audience carries a kind of evidence no certificate or advertisement can replicate.

the move

While demonstrating the safety of the company's 'sheep fat soap' to newly hired staff, Qi Dexin picked up a bar of Red Guard's own soap and bit into it on camera, stating there was nothing harmful inside. The demonstration, originally recorded for internal staff training roughly two to three months earlier, was filmed and uploaded by an employee without his direct knowledge; once it circulated online it was widely reported in the press as a live broadcast specifically staged to prove the product's safety, a framing Qi later clarified in interviews wasn't quite accurate to how the video originated.

why it works

Because eating a product you claimed contains no harmful additives is something no one would do if the claim were false and the risk were real, the demonstration converted an unverifiable assertion into a costly, credible signal — the chairman's own body became the proof, not another document asserting the same thing every rival already asserts. Because the moment was genuinely unscripted for public consumption, originally recorded for internal staff training rather than produced as a calculated publicity stunt, it read to viewers as authentic conviction rather than as a rehearsed marketing performance, which is part of why it broke through where deliberate advertising claiming the same thing routinely fails.

the payoff

The clip drove Red Guard's daily sales from roughly ¥100,000 to about ¥2,000,000, a twentyfold increase, according to Qi Dexin's own account in a subsequent interview, and the company expanded its staff from 72 to more than 100 employees to meet the surge in demand, temporarily pausing sales of its flagship product for several days to manage inventory and logistics. Contemporary press coverage described strained store inventory and rapidly selling-out product bundles in the days immediately following the video's spread online.

where it breaks

The mechanism only works if the underlying claim is actually true and the demonstrator is genuinely willing to bear real personal risk to make it — a costly signal that turns out to be faked or staged destroys trust far more thoroughly than an ordinary unverified claim would have, since the entire credibility of the moment rests on its authenticity. It's also a one-time, hard-to-repeat move: once a brand has made its costly demonstration, doing it again doesn't carry the same shock value or credibility premium, and competitors who understand the mechanism can attempt the same stunt, diluting its distinguishing power across the category.

what came after

The Red Guard soap-eating clip became a widely discussed example in Chinese consumer-marketing commentary of a heritage domestic brand using a personally costly demonstration to cut through category-wide claim fatigue, contributing to a broader 2023 wave of attention toward older Chinese manufacturing brands revitalized through livestream and short-video commerce, and Qi Dexin's own account of the sales surge and staffing expansion has been cited as a concrete example of the demonstration's measurable commercial impact.
