Why Precipitated Silica is The Secret to Clump-Free Laundry Powder

How Precipitated Silica Works

Silica is created using a green chemistry process: sodium silicate is reacted with sulfuric acid under controlled conditions, forming a fine white powder derived from purified sand. So it’s naturally abundant, safe, and non-reactive—a true multitasker that quietly ensures your detergent performs the way it should.

Why do We Use Precipitated Silica and Is it Safe?

At Truly Free Home, we chose precipitated silica because it supports product quality and cleaning performance from pouch to jug. By preventing clumping in our Signature Scent and Unscented Laundry Wash, it ensures you get a smooth mix every time you add it to your reusable jug with water, so your laundry detergent works effectively, load after load. while staying safe and family-friendly. 

And with an Environmental Working Group (EWG) rating of 1—the safest score possible—when used in liquids, precipitated silica aligns with our commitment to clean, non-toxic ingredients.

From laundry detergent to toothpaste, silica shows that even the smallest ingredients can make a big difference.
