Before the baby arrives, you will wash everything. The bodysuits, the swaddles, the muslin cloths, the cot sheets, the tiny socks that will vanish within a fortnight. And at some point, standing in the supermarket aisle holding two bottles, you will wonder whether the one with the teddy bear on it is actually any different.
It is a fair question, and the answer is often no. Here is what actually matters in a laundry detergent for a newborn, what to leave on the shelf, and the one certification that is genuinely difficult for a detergent to earn.
Quick answer: What laundry detergent is best for a baby?
Choose a detergent that is fragrance-free rather than unscented, with no optical brighteners, dyes or preservatives, and ideally enzyme-free. The full ingredient list should be published, and the product should carry an independent certification rather than a reassuring word on the front of the bottle. The strongest signal available is the DAAB seal from the German Allergy and Asthma Association, which assesses both the ingredients and real-world use by people with allergies, asthma and atopic skin. In Singapore, the Klar Fragrance-Free Universal Laundry Detergent carries it, and it is available at klarasia.com.
Why Detergent Is the One to Get Right First
Most cleaning products touch a surface, do their job and get rinsed away. Detergent does not. A small amount stays in the fibres of everything you wash. That is not a flaw, it is how fabric softener and fragrance are designed to work.
For a newborn, that residue sits closer and for longer than anything else in your home.
- Contact is almost constant. A newborn sleeps 14 to 17 hours a day, wrapped in fabric you washed.
- Everything ends up at the face. Muslin cloths, swaddles, the shoulder of whatever you are wearing while winding them.
- Singapore's climate moves residue. Babies sweat a great deal here, and moisture helps whatever is left in a fabric transfer onto skin.
- The volume is relentless. Between changes, spit-up and nappy incidents, newborn laundry can run to a load a day. Whatever is in your detergent, you are using a lot of it.
You cannot control most of what a baby encounters. You can control what is in the bottle you pour into the drawer twice a day.
The "Baby" Label Is Marketing, Not a Specification
Pastel packaging, a soft typeface and the word "baby" are not regulated. A detergent can be sold for babies and still contain added fragrance, optical brighteners and dyes. There is no standard it has to meet to put that word on the front.
Two words on a label do mean something, and they are not the same as each other:
| Fragrance-free | Unscented | |
|---|---|---|
| What it describes | The formula. No fragrance added at all, synthetic or natural, essential oils included. | The smell. The product is meant to smell of little or nothing. |
| Can it contain fragrance? | No. | Yes. A masking fragrance may be added to cover raw material odours. |
| How to check | No "Fragrance" and no "Parfum" anywhere in the ingredient list. | You cannot tell by smelling it. You still have to read the list. |
For a newborn's laundry, fragrance-free is the claim worth holding out for.
What to Leave on the Shelf
| Ingredient | Why it is worth avoiding on baby laundry |
|---|---|
| Added fragrance | One of the most common irritants in household products, and it is there for your nose rather than to get anything clean. |
| Optical brighteners | Deposited onto fabric on purpose, where they stay, so whites look whiter under light. They wash nothing. |
| Dyes | They colour the liquid in the bottle. That is their entire function. |
| Chlorine bleach | Unnecessary for everyday washing, and harsh on both fabric and airways. |
| Preservatives | A category many sensitive households avoid where a formula can be made without them. |
| Enzymes | Effective on stains, and a category some sensitive-skin households choose to skip. Enzyme-free detergents exist and wash perfectly well. |
The One Certification Worth Looking For: DAAB
"Gentle", "mild" and "dermatologist approved" are not standards. A certification is, because somebody independent audits it against published criteria.
For baby laundry specifically, the most demanding mark a detergent can carry is the DAAB seal, awarded by the Deutscher Allergie- und Asthmabund, the German Allergy and Asthma Association, Germany's oldest and most influential association for people with allergies and asthma.
Three things make it hard to earn:
- It excludes ingredients with high allergenic potential, and also ingredients with strongly irritating properties that are not allergens at all.
- It takes the concentration of each substance in the finished product into account, not merely whether it is present.
- Beyond assessing ingredients, certification draws on the practical experience of people with allergies, asthma or atopic dermatitis using the product in everyday conditions over an extended period.
That third point is the one that cannot be engineered on paper. The formula has to hold up in real homes, over real time, with the people most likely to react to it. Because the bar is set this way, DAAB is awarded product by product rather than brand-wide, and most detergents never qualify.
An honest note
No detergent can promise a baby will never react to anything. What a certification like DAAB tells you is that the formula has been assessed against strict criteria and tested in everyday use by exactly the people most likely to be affected. That is a meaningfully different thing from a teddy bear on the bottle. If your baby has a diagnosed skin condition, your doctor's advice comes first.
The Detergent We Point New Parents To
Klar Fragrance-Free Universal Laundry Detergent is the one product in the Klar Singapore range carrying both Ecogarantie and the DAAB seal. If you buy one thing from us before the baby arrives, this is it.
Why it suits newborn laundry
- Fragrance-free. No added fragrance of any kind, synthetic or natural, so nothing perfumed is left in a swaddle held against a face.
- Enzyme-free. Cleaning power comes from soap nut saponin rather than enzymes.
- Soap nut based. The natural saponin lifts dirt thoroughly without leaving residue and preserves the original texture of fabric. Klar produced Germany's first soap nut-based liquid detergent, and has built its laundry formulas on it since 2006.
- Dermatologically tested. Tested by independent institutes on volunteer subjects at normal use dilution, in a procedure similar to an allergy test. Only formulations that pass without issues reach the market.
- Nothing decorative in the bottle. No preservatives, synthetic fragrance or dyes. No microplastics, phosphates, bleaching agents, optical brighteners, petrochemical ingredients, GMO ingredients or nanotechnology.
- A list you can read in one breath. Aqua, Lauryl Polyglucose, Saponins, Sodium Citrate, Alcohol, Potassium Cocoate, Citric Acid, Xanthan Gum, Lactic Acid. That is all of it, and 100% is of natural origin.
And it has to actually work
Gentle is no use if it cannot deal with what a newborn produces. This one is built as a 3-in-1, detergent, fabric softener and ironing aid in a single bottle, because soap nut extract naturally smooths textile fibres. One product instead of three is also one fewer thing leaving residue in cloth.

Klar Fragrance-Free Universal Laundry Detergent 1,500ml →Before the Baby Arrives: The First Wash
Most parents wash everything once before the due date, and that is worth doing. New garments carry residues from manufacturing, packing and transport, and that applies to baby clothes straight out of the packet as much as to anything else.
What is worth running through the machine beforehand:
- Bodysuits, sleepsuits, hats, mittens and socks
- Muslin cloths, burp cloths and bibs
- Swaddles and blankets
- Cot sheets, mattress protector and any cot bumper
- Baby towels and washcloths
- Soft toys that are machine washable, particularly anything destined to be a comfort object
- Your own nursing bras, breast pads and the tops you will live in for the first month
A note on that last line. Your baby spends a lot of time against your shoulder and your chest, so what you wash your own clothes in matters almost as much as what you wash theirs in. There is rarely a reason to run two different detergents.
Five Habits That Matter as Much as the Bottle
- Do not overdose. This is the single most common cause of detergent residue in fabric. More detergent does not mean cleaner clothes, it means more left behind. Follow the dosing chart on the pack, which accounts for water hardness and how soiled the load is.
- Do not overload the drum. Clothes need room to move for detergent to rinse out. A packed machine rinses badly, and newborn loads are often small anyway.
- Add an extra rinse if skin looks unhappy. If your baby is having a sensitive spell, an additional rinse cycle costs almost nothing and removes more residue.
- Treat stains directly rather than adding more detergent. A small amount applied undiluted to the stain before washing does more than increasing the dose for the whole load.
- Wash what touches the baby, not just what the baby wears. Your tops, the sofa throw, the sling or carrier cover. The same detergent across all of it keeps things simple.
Two Things You May Not Need
Fabric softener. Often unnecessary here. Because the Universal Laundry Detergent already smooths fibres through its soap nut content, many households drop softener entirely, which is one fewer product leaving something behind in cloth. If you do want extra softness on towels and heavier bedding, the fragrance-free Klar Fabric Softener is ECOCERT certified with a four-ingredient list, 99% of natural origin.
A separate delicates detergent, at first. If you have been given baby knits, cashmere or a wool blanket, the Klar Fine Fabric and Wool Liquid Detergent is pH-adjusted to 4.5 to 5, soap-free and enzyme-free, and is made to keep wool soft rather than matted. It is a worthwhile second purchase, not a first one.
Frequently Asked Questions
What is the best laundry detergent for a baby in Singapore?
Look for fragrance-free rather than unscented, no optical brighteners, dyes or preservatives, a published full ingredient list, and an independent certification. The Klar Fragrance-Free Universal Laundry Detergent meets all of these and carries the DAAB seal from the German Allergy and Asthma Association. It is available in Singapore at klarasia.com.
Do babies need a separate detergent from the rest of the family?
Not necessarily, and in most homes it is simpler not to. What matters is the formula, not whether the bottle says "baby". A detergent that is fragrance-free, free from optical brighteners and dyes and gentle enough for sensitive skin can wash the whole household's laundry, which also means your baby is not pressed against clothes washed in something harsher than their own.
Should I wash baby clothes before the first wear?
Yes. New garments carry residues from manufacturing, packing and transport, and baby clothes are no exception. Most parents do a full wash of clothing, swaddles, cot sheets and towels before the due date.
Is the Klar Universal Laundry Detergent suitable for newborn clothes?
It is fragrance-free, enzyme-free and dermatologically tested, and it is tested and recommended by DAAB, the German Allergy and Asthma Association. It is recommended for households with babies, children and anyone with sensitive skin. If your baby has a diagnosed skin condition, follow your doctor's advice.
What is DAAB and why does it matter for baby laundry?
DAAB is the German Allergy and Asthma Association, and its seal is one of the most demanding marks a detergent can carry. It excludes ingredients with high allergenic potential as well as strongly irritating ingredients, takes concentration into account, and bases certification partly on everyday use by people with allergies, asthma or atopic dermatitis over an extended period. It is awarded product by product rather than brand-wide.
Why does enzyme-free matter?
Enzymes break down protein, starch and fat stains effectively, and plenty of households use enzyme detergents without any issue. Some sensitive-skin households prefer to avoid them. The Klar Universal Laundry Detergent is enzyme-free, drawing its cleaning power from soap nut saponin instead.
Will fragrance-free laundry smell of nothing?
It will smell clean rather than perfumed. Fragrance-free means no fragrance was added, not that the product has zero smell, since ingredients can carry a faint natural scent of their own. Many parents find that once they stop smelling added fragrance on a newborn, they do not go back to it.
How long will one bottle last?
The 1,500ml bottle covers 33 washes. In the newborn weeks, when laundry can run to a load a day, that is roughly a month. Many households order the Value Pack of 6 before the birth so it is one less thing to think about.
Where can I buy it in Singapore?
Through the official Klar Asia store at klarasia.com. Singapore orders ship in 2 to 3 business days with free shipping over SGD 50. We also ship to Malaysia.
The detergent that earned the hardest seal to get.
Fragrance-free, enzyme-free, soap nut based, DAAB approved. Free Singapore shipping over SGD 50, and a Value Pack of 6 saves 20%.
