If someone in your house has sensitive skin or eczema, you already know the laundry isn't a small decision. The wrong detergent can mean itchy nights and scratched arms; the right one just quietly disappears into the routine. Here's an honest guide to what actually matters when you're choosing — because most of the marketing misses the point.
The three ingredients to avoid first
Eczema organisations and dermatologists keep coming back to the same short list of common triggers:
- Fragrance. The most common culprit by far. "Unscented" sometimes just means masking fragrance — look for genuinely fragrance-free.
- Optical brighteners. These are chemicals designed to stay on your clothes after the wash, absorbing UV light so whites look whiter. Something engineered to remain in the fibres sits against your skin all day — exactly what a sensitive-skin wash should avoid.
- Dyes. They add nothing to cleaning performance and are a known irritant for reactive skin.
The trigger nobody talks about: leftover detergent
Here's the overlooked one. Even a "gentle" detergent becomes an irritant if it doesn't rinse out — and the biggest cause of detergent left in fabric is simple overdosing. With liquids and powders, most of us pour by feel, and the cap in your hand usually holds two or three doses. That excess doesn't all rinse away; it stays in the weave of a school shirt or a pillowcase, right against the skin.
This is where pre-measured formats quietly win. A dissolvable detergent sheet takes the guesswork out completely: half a sheet for a standard load, a full sheet for large (8kg+) or heavily soiled loads. The dose is right every time, so excess detergent isn't left sitting in the fabric.
A checklist for sensitive-skin households
- Genuinely fragrance-free — not "lightly scented"
- No optical brighteners, no dyes
- Plant-derived surfactants over harsher petrochemical blends
- Pre-measured, so you can't accidentally overdose
- Dissolves completely in hot and cold water — undissolved product is residue by another name
Where DSSLV Scent Free fits
We made our Scent Free laundry sheets for exactly these homes — including our own. Every DSSLV laundry sheet is free from optical brighteners and dyes, built on plant-derived surfactants with coconut oil and soapnut extracts plus cleaning enzymes, and the Scent Free version leaves fragrance out entirely. The sheets dissolve completely in any machine — front loader, top loader, hot or cold — and they're septic and grey-water safe. One slim pack holds 40 sheets, good for up to 80 loads. You can read the full ingredients rundown here.
We built them for exactly these washes — baby clothes included — with no perfume cloud, just clean fabric.
A gentler wash routine (beyond the detergent)
- Wash new clothes before first wear — fabric finishes from manufacturing are a common irritant.
- Add an extra rinse during flare-up periods, especially for bedding and anything worn against skin.
- Skip heavily fragranced softeners and scent boosters. A softening agent is already part of the DSSLV sheet formula, so there's nothing extra to add.
- Line-dry in the sun where you can — it's free, and UV is a natural freshener.
- Change one thing at a time. If you're troubleshooting a reaction, switch only the detergent for a few weeks so you actually know what helped.
One honest note: laundry choices can reduce exposure to common irritants, but they're not a treatment for any skin condition. For persistent eczema, your GP or dermatologist is the right first stop — this guide just makes sure the washing basket isn't working against you.
