At SENZA, we understand these situations – and we've come up with a truly economical, ecological and practical solution.

Bulk, refill, bottle: which is the best option?

Between marketing and reality, it's hard to know what's what. We'll help you sort it out: bulk laundry detergent, bottled laundry detergent, or eco-designed refill? We'll help you choose the right laundry detergent, simple, effective, and free of toxic ingredients.

Why buy laundry detergent in bulk?

• Economical: the price per liter drops significantly with family sizes or concentrated refills.
• Ecological: less packaging, fewer deliveries, less plastic.
• Practical: no more trips to the store every two weeks.

But for it to be a truly good deal, you still need to choose a good laundry detergent.

Pitfalls to avoid: large bottle ≠ good composition

Pitfalls to avoid: large bottle ≠ good composition

Beware of false bargains: many cheap bulk laundry detergents contain:

• Allergenic fragrances (even those called “natural”), sometimes associated with substances suspected of being endocrine disruptors,
• Controversial preservatives,
• Optical brighteners, colorants, foaming agents, etc.

5 criteria for choosing your bulk laundry detergent

1. Price per liter: If you save more than 25%, it's a really good deal.
2. Composition: Fewer than 5 ingredients, simple and legible names? That's a good sign.
3. Daily utility: Is it effective for the whole family? For babies? Sensitive skin?
4. Packaging: Reusable, recycled or returnable bottle? Prefer sustainable formats.
5. Transparency: Clear INCI, origin of ingredients, official labels, no greenwashing.

Buy in bulk, yes... but according to your needs

Buying 20 liters of laundry detergent is great – but is it suitable for your space, your budget, and your lifestyle?

• Calculate your needs for 3 to 6 months.
• Check available storage space (cupboard, cellar, laundry room).
• Avoid waste: our natural laundry detergents without preservatives keep better away from light and in a dry place.

Bulk Laundry Detergent Purchase for Individuals - FAQ

Why buy laundry detergent in bulk?

Buying in bulk allows for significant savings on the price per liter, reduces packaging and deliveries, and ensures you always have laundry detergent available. It's a choice that is both economical, practical, and ecological.

How many washes can you do with a 5-liter container?

With a concentrated detergent like SENZA's, a 5L container allows for approximately 100 washes, which means several months of laundry depending on your usage.

Does bulk laundry detergent keep well?

Yes, provided it is stored properly away from light, heat, and humidity. Natural detergents without preservatives, like those from SENZA, are more sensitive: it is advisable not to store more than 3 to 6 months' worth of use.

Can you buy in bulk if you have a small laundry room?

Yes, but you need to anticipate the available space. If you are short on space, opt for 5L or 10L formats rather than 20L containers, or use more compact secondary containers.

Is it really more economical to buy in bulk?

Yes: the price per liter drops significantly. With SENZA, for example, the cost per wash goes down to €0.35 in 5L format. This is often cheaper than supermarket detergents, with much higher quality.

Where can you buy bulk laundry detergent in France?

You can order directly from senza-nature.fr. Delivery throughout France. In Île-de-France, you can even benefit from professional rates from 60L ordered.
