Why choose the right laundry detergent for washing cloth diapers?

Using an unsuitable laundry detergent can clog fibers, reduce absorbency, and irritate your baby's skin. Knowing the composition of your detergent allows you to optimize the dosage and performance, while ensuring an eco-friendly and effective wash.

Surfactants: the heart of cleaning

It is the active molecules that remove impurities and residues. They reduce the water's tension to effectively detach dirt. There are three main types:

• Anionic surfactants – effective against stubborn stains, but potentially irritating in excess;
• Non-ionic surfactants – powerful degreasers, ensuring thorough rinsing;
• Amphoteric surfactants – gentle and balanced, perfect for sensitive skin.

Bleaching agents for bright, vibrant diapers

To remove stains and revive fibers, opt for natural bleaching agents:

• Sodium percarbonate : ecological stain remover and sanitizer;
• Hydrogen peroxide : restores shine without damaging the fibers.

⚠️ Avoid bleach, which damages PUL and irritates baby's skin.

Preservatives and their impact on the skin

Liquid laundry detergents often contain preservatives to prevent bacterial growth. Some, however, can be allergenic:

• Methylisothiazolinone (MIT) : effective antibacterial, but sensitizing;
• Benzisothiazolinone (BIT) : powerful, but to be used judiciously;
• Methylbenzetoquonium chloride : an antifungal to be avoided in the long term.

Perfumes and their natural alternatives

Perfumes are often responsible for skin irritations. For babies, it's best to avoid overly complex compositions.

• Synthetic perfumes : common allergens;
• Essential oils : natural, but some are not recommended before the age of 3.

Tip: A neutral laundry detergent, without perfume or dye, guarantees a safer and gentler wash for the skin.

Additives and their role in washing reusable nappies

Some additives improve washing, but in excess they can clog the fibers and impair absorption:

• Anti-redeposition agents : prevent dirt from redepositing on the fabric;
• Stain removers : useful but should be used in moderation;
• Dispersive agents : limit detergent deposits in diapers.

Conclusion and practical advice

Understanding the ingredients in your cloth diaper detergent helps optimize your routine and extend the life of your textiles. By choosing a simple formula, free of perfumes and harsh additives, you ensure an effective wash that's kind to both your skin and the planet.
