Hi I got this off a home essentials website -
Biological and Non-Bio - What is the difference?
Biological and Non-Biological
What is the difference between Bio and Non-Bio?
All washing powders have a surfactant base which is the 'workhorse' of the product. For Ecover the surfactants are derived from plant based ingredients as opposed to petrochemical surfactants used in a conventional product.
The main difference between a Biological Washing Powdersand a Non-Biological Washing Powder iproduct is that a non-biological product doesn't contain enzymes. To increase the performance of a conventional washing powder oxygen bleach i is added which helps in the removal of stains such as grass. However not all stains are bleachable and therefore enzymes are also added to produce biological laundry products which are better at removing fatty or protein based stains such as blood and egg.
This is off YAHOO questions and answers
Bio tends to do a better job of cleaning organic stains like grass and food because it contains biological cleaning agents but that leaves residues in the material which can continue to actively "digest" and disintegrate organic material. It's a mild effect but can cause irritation of sensitive skin. In extreme cases it can cause clothes to literally fall apart. Persil used to have a brand that did just that and had to be withdrawn.
Non-Bio detergents don't work quite so well as organic versions but they don't leave the irritating residues which is why they're recommended for babies clothes in particular.
I am allergic to biological powder.... I am sure i used that persil washing powder as when I was about 11 I had major skin irritation and doctor said it was enzymes from washign powder eating my skin!!!!!
We use Faith in Nature washing liquid for all our washes. It is great, got to say it doesn't leave it smelling as fresh/nice as something like fairy non-bio (what we used to use) but it cleans just as good, and it's natural.
For poo/wee stains on LO's clothes I soak in VANISH and then wash as normal.

Hope this helps.
