Silicic acid (H4SiO4), disodium salt, reaction products with chlorotrimethylsilane and 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10- heptadecafluoro-1-decanol

Water-/oil-repellent coatings for textiles, leather, paper/packaging, sealants, and anti-smudge finishes; manufacturing waste [1][2].

Wearing/using treated goods; indoor dust and air; drinking water near production, fire-training sites, or landfills; workplace skin or inhalation [1].

Data for this exact chemical are limited, but many fluorinated treatments can shed or degrade to PFAS. Some PFAS are linked to immune effects, higher cholesterol, liver/thyroid changes, reproductive effects, and certain cancers [1][2].

Fluorochemical workers; people near contaminated sites; pregnant people, infants, children; private-well users [1].

Choose “PFAS-free/fluorine-free” products; skip optional stain-resistant sprays; wet-dust/HEPA vacuum; check water; use certified activated-carbon or reverse-osmosis filters; follow workplace PPE/hygiene [2][3].
