Bio vs non-bio laundry detergent: What’s the difference?

When it comes to cleaning clothes, all of the lotions and potions can leave you feeling like you need a science degree to use your washing machine, especially when you're trying to decide between bio vs non-bio detergents.

It might seem confusing, but we're here to talk you through each option so you can make the best choice for your laundry needs, no matter if you're using a regular washing machine, a portable washing machine or hand-washing your garments.

Whether you're dealing with stubborn stains, sensitive skin, unpleasant food or sweat smells or just trying to make sense of all the labels, understanding the difference between biological and non-biological detergents can make laundry day a whole lot simpler. Plus, we’ll share a few helpful suggestions to point you in the right direction.

Bio vs non-bio laundry soap: What is the difference?

Put simply; biological detergents contain enzymes that actively break down dirt on fabric, common stains like food, sweat, and grease, making them highly effective at cleaning clothes, even at lower temperatures. Non-biological detergents, on the other hand, don’t include these enzymes, which makes them a gentler option - especially for those with sensitive skin or allergies.

Benefits of bio detergent

Common stains like food, sweat, and grease are no match for biological detergents, which makes them highly effective at cleaning clothes and most everyday fabrics such as cottons, linens, and synthetics.

They’re effective even at lower temperatures, thanks to the enzymes they contain, which can help you save money over time by reducing energy use, extending the life of your washing machine and helping your clothes last longer compared to frequent high-temperature washes.

Benefits of non-bio detergent

Non-biological detergents don’t have enzymes, making them less harsh on fabrics and a gentler choice for people with sensitive skin or allergies. They tend to be the best option for those looking to avoid irritation. Many parents or carers also choose non-bio when washing clothes for babies or small children, as their skin is naturally more sensitive.

Additionally, non-bio is preferable for delicate fabrics like silk and wool, as they are made out of proteins that can be damaged by the enzymes in bio detergents (similarly to how they can break down food stains). So, you may find that these fabrics will wear out more quickly if you're washing them with bio detergent.
