EK USA (also marketed as EK Ekcessories and EK World Wide) is the manufacturer behind the long-running Cat Crap line of anti-fog and lens-cleaning products. The brand's catalog spans outdoor accessories, but the Cat Crap formulas — sold in both paste and pump-spray formats — are the most recognized SKUs, with a community footprint across ski, snowboard, dive, shooting, and automotive use cases.
The Cat Crap line uses a simple food-grade-style formulation (coconut tallow soap, glycerin, water as the disclosed ingredient panel) and has been on the market in essentially the same form for over a decade. EK does not publicly host GHS Safety Data Sheets on the consumer-facing brand site, which is gated to non-residential traffic; downstream safety-eyewear distributors (Phillips Safety, Magid, Emergent Safety) carry product information sheets but no standalone GHS SDS as of 2026-05-19. CarCareTruth treats EK USA's Cat Crap products as no-SDS-on-file under the standard 3.0/10 Health Score policy until a documented GHS SDS is sourced.
