Washing Powder

[Linzi84]

What is the difference between Biological and Non-Biological Powder? A label in one of my tops said to use Non-Bio powder, but I read this after it had been washed with Bio, and the top was all static and made a cracking sound when I pulled it on. Would this be the reason why because I used the wrong powder?

Bio washing powders contain active enzymes which 'digest' organic stains, such as those from food. These stains contain proteins which can be hard to shift. For example in our bodies a particular enzyme may digest a protein in tomatoes, so that very enzyme can be put in bio washing powder to be effective against tomato ketchup stains.

I can't think of a reason why a top couldn't be washed with bio powder, but I guess there must be one and I should think its due to the enzymes, maybe there's some delicate natural fibres in it - wool and other animal hair are also proteins after all and i guess could be damaged by the enzymes.

I doubt it has been ruined, just use non-bio next time.

If a top is a natural fibre, e.g. cotton or silk, then use of bio powder would break down the fabric eventually. It also affects dye colour if natural dyes have been used.

I think the reason will be that biological powders usually have bleaches as well as enzymes and the bleaches fade the colour of garments. Also if there are any metally bits on your garment they can be spoiled by biological powders. I keep some non biological powder for hand washing delicate garments.
