MamaSuds Laundry Soap

Important note on laundry detergents

Laundry detergent is one of the products I’m most mindful about because it sits on fabric that touches your skin all day — towels, sheets, underwear, socks, and kids’ clothes. A lot of conventional detergents rely on fragrance, brighteners, or “boosted” additives to signal clean, but those extras can linger on fabric and don’t always support sensitive skin.

I prefer laundry options that clean well and rinse clean, without unnecessary ingredients that build up over time.

What I avoid in laundry detergents

In this category, I avoid undisclosed or toxic fragrance blends, optical brighteners, harsh surfactants like SLS/SLES, ethoxylated ingredients (such as PEGs or ingredients ending in “-eth”), quaternary ammonium compounds (quats), methylisothiazolinone (MIT), and formaldehyde-releasing preservative systems. I also skip solvent-type additives and fillers that don’t contribute to actual cleaning and can leave fabrics feeling coated.

What I look for instead is a straightforward, fully disclosed formula that relies on true soap or simple cleaning agents and rinses out well.

Product description

MamaSuds Laundry Soap is a castile-based laundry soap made with a short, recognizable ingredient list. It’s designed for everyday washing without relying on fragrance systems, optical brighteners, or heavy detergent additives.

This is the kind of laundry soap I reach for when I want clothes and linens to come out clean and fresh without smelling like detergent.

What I like

I like that the formula stays simple and transparent instead of leaning on “extra power” additives.

I also appreciate that it doesn’t leave fabrics heavily scented or coated.

Things to keep in mind

Because this is a soap-based product, hard water can affect performance. Adjusting the amount used and rinsing well can help.

For tougher stains, pairing this with a separate pre-treat step makes a difference.
