Ingredient details
Optical brighteners are synthetic chemicals added to products such as laundry powders, liquid, soakers and other cleaning products to give an illusion of cleaner surfacesii. In laundry powders they adhere to clothesiv and reflect light in the blue spectrum while absorbing UV light. This makes clothes appear whiter and cleaner but really they are just unnecessary ingredients added for aesthetics. Although there is limited evidence available suggesting skin irritation for optical brighteners, because they are designed to stick to clothes, they end up being in contact with skin for prolonged periods of time, which can be a cause for concern when considering the effects of these chemicals on skin and possible irritation. Optical brighteners can also end up in waterways, where they are slow to biodegradeiv and can therefore cause long term effects on the aquatic environment. They can also adhere to plants, where their UV absorbing effects can affect pollination by beesvii.
