Stain repellent
A stain repellent is a product added to fabric in order to prevent stains.[1]
Stains
[edit]Stains on fabrics are classified into three types: water-based stains and oil-based stains or a mix of both.[2]
Stain repellant fabrics
[edit]Fabrics are finished with certain finishes that do not allow unwanted stains or that will wash out in simple laundry.
Chemicals
[edit]Mostly larger PFCAs such as perfluorooctanoic acid (PFOA) are used in stain repellancy. It is also known colloquially as C8. PFOA is a product of health concern and subject to regulatory action and voluntary industrial phase-outs.[3]
Alternative chemistry
[edit]There are chemicals which are based on C8 free chemistry that may be used as an alternative to PFOA, but those are less durable.[4]
