Each year, we conduct authenticity testing to validate product quality, explore consumer concerns, support product authenticity claims, ensure regulatory compliance, and build trust in our brand commitment to provide a product that is safe for both people and the environment.
In 2010, our finished products and packaging were selectively screened for 1,4-dioxane, formaldehyde, pesticides, hypochlorite, phosphates, 60 different metals, methanol, latex, dioxin, nitrosamines, benzene, and organic halides (chlorine in fibers) by third-party, independent laboratories using standardized methodologies. As we ask more and more of our suppliers before we use their ingredients, we find that the authenticity testing is verifying our stringent product requirements.
For the first time, we are incorporating carbon-14 testing, a variation of the radiocarbon dating methods long used to determine the age of ancient artifacts, to confirm the bio-based carbon content of Seventh Generation formulations. Based on our knowledge of our ingredients, we always calculate the Renewable Carbon Index for our products. Carbon-14 testing provides an exciting way to verify the amount of plant-derived versus petroleum-derived carbon in our products. From this work, we are able to confirm the authenticity of our products, as well as uncover opportunities for improvement — including changes in formulation and raw material sourcing — that will allow us to strive for even higher renewable carbon content.
We continue to test our products as new consumer or raw material sourcing concerns arise and always strive to stay ahead of the curve in protecting human and environmental health.
