What the Delhi High Court's Beco injunction changes for comparative ingredient claims
The Delhi High Court's interim injunction against Beco demonstrates that technically accurate ingredient claims can still constitute commercial disparagement if the overall campaign implies a competitor's finished product is unsafe.
On September 10, 2026, the Delhi High Court granted Hindustan Unilever Limited (HUL) an interim injunction against Kwick Living (I) Private Limited, the operator of home-care brand Beco. Justice Anup Jairam Bhambhani directed Beco to pull down its “#WarOnWhatsHidden” advertising campaign across all media formats within one week. The campaign explicitly named HUL’s Surf Excel and Vim, highlighting the presence of synthetic compounds Benzisothiazolinone (BIT) and Linear Alkylbenzene Sulfonate (LAS) to suggest the products cause skin irritation and allergic reactions.
The core legal issue is the boundary between permissible comparative advertising and commercial disparagement. The court held that even if individual ingredient-level claims are technically accurate, a campaign crosses the legal line when its holistic message misleads an average consumer into believing a competitor’s finished product is physically harmful. The order noted that an average consumer lacks the expertise to deconstruct complex chemical proportions, meaning the campaign denigrated HUL’s products under the guise of a verified scientific basis.
For in-house counsel reviewing marketing materials, this order clarifies the evidentiary standard for comparative campaigns. A brand cannot defend an aggressive advertisement merely by proving that a specific chemical causes irritation in isolation. Legal review must evaluate the overall impression the advertisement creates.
When reviewing sustainability or “clean label” marketing, legal teams must ensure that highlighting a product’s differentiated formulation does not rely on denigrating a rival’s safety. Operationally, this requires marketing review protocols that test the consumer takeaway of the entire campaign, rather than just verifying the technical accuracy of isolated scientific claims. Legal operations leads must establish clear boundaries for marketing teams: comparing efficacy is permissible, but isolating raw ingredients to suggest a competitor’s standard product is dangerous constitutes actionable disparagement.
