Our products may contain animal-derived ingredients from normal sustainable animal husbandry or farming or fishery practices such as milk, honey, lanolin, silk etc. Products may also contain processed and denatured animal by products with established uses such as tallow, keratin, collagen, elastin etc. In most cases, this is because the ingredient performs a function for which there is no suitable alternative available. Animal welfare is an important social and ethical issue. As part of our Sustainable Agricultural Code, we work with suppliers to continuously improve the sourcing of agricultural ingredients.
