Mae microbelenni plastig wedi’u hychwanegu at amrywiaeth o gynhyrchion gofal personol ers blynyddoedd, gan gynnwys cynhyrchion glanhau dwylo, sgrybiau wyneb, pastiau dannedd, geliau i'w defnyddio yn y gawod, a chosmetigau.
Plastic microbeads have been added to a variety of personal care products for many years, including hand cleansers, face scrubs, toothpastes, shower gels and cosmetics.
