for most water-based products, the use of a preservative is necessary. at method, we always use safe, environmentally compatible preservatives in the products we need to preserve. these preservatives keep the product safe and effective over the life of the product.
what we do: preservatives
effective
method formulations are typically 95 to 99% naturally derived ingredients, so effective preservatives are required to keep them from spoiling and to maintain their effectiveness and safety over time. by choosing effective preservatives, we can use them at ultra-low concentrations (under 0.1% for most of our cleaners).
comprehensive assessment
all of the preservatives used in method products have been comprehensively assessed by the material scientists at EPEA, so we can be certain of their full health + environmental profile. this research allows us to be sure that our formulations remain non-toxic and biodegradable.
biodegradable
all preservatives used in method products are biodegradable, meaning they are effectively removed in water treatment and will not accumulate in natural environments.
