Approved Ingredients


Carrageenan is an extract derived from families of red seaweed (Rhodophyceae). We use this ingredient in our toothpastes to help thicken the product.

Carrageenan is actually the name for a group of carbohydrates (polysaccharides), which can be produced from different seaweed species including Elkhorn Sea Moss (Kappaphycus alvarezii) and E. spinosum (Eucheuma denticulatum). These seaweed are cultivated on lines set in the ocean, harvested, dried and then shipped to a plant for milling and further processing.

Processed carrageenan usually appears as a white or beige powder, and has many useful binding, thickening, gelling and stabilising properties. It's used in food products to gelatinise certain proteins, and can be found in some yoghurts, ice creams and cottage cheeses. This ingredient can also be used as a stabiliser in toothpastes and shampoos.
