Replace vague terms like “eco,” “green,” or “planet-safe” with specific, testable statements. For example, define the ingredient change, the percentage improvement, and the measured impact. If a benefit applies only to packaging or transport, say so plainly. Readers appreciate candor about boundaries and trade-offs, especially when you explain how you will continue improving and how they can verify the current claim.
Comparatives require a clear baseline. State whether you’re comparing to a prior formula, a category average, or a named competitor study. Quantify differences with ranges and confidence where available. Clarify scope: raw materials, manufacturing, transport, use, or end-of-life. If data is modeled, name the model. Link to supporting methods, assumptions, and datasets, so third parties can understand limitations and avoid misinterpretation.
“Free-from” claims must be truthful, relevant, and non-misleading; avoid implying that competitors commonly use a substance when they do not. “Non-toxic” can imply safety across all exposures and contexts, which is rarely supportable. Prefer hazard-and-exposure clarity, e.g., “Meets EPA Safer Choice human health criteria for acute toxicity.” Provide safety data sheets and explain safe use, storage, and disposal in plain language.
