Composite verdict

Composite Safety Score: 57/100

One verdict blending 4 independently-sourced dimensions from two separate CPSC systems, each benchmarked against all 838 scored product categories by percentile rather than raw value, so no single huge-volume category can dominate the scale.

C
Dimension Value National percentile Weight applied Source
Injury severity (hospitalization + fatality blend) 22 94th 35% CPSC NEISS 20-year severity index

Methodology: each dimension is ranked against the full population's p10/p25/p50/p75/p90 breakpoints and interpolated to a 0-100 percentile; the composite is the weighted average of available percentiles. See methodology for the full benchmark table.

How this 42/100 score is built

The score is computed from four CPSC-derived factors for lye - no opinion, no editorializing:

  • Injury volume 287 ER visits/yr Low volume
  • Severity (hospitalization rate) 21.8% Very high admission rate
  • Fatality rate 0.00% No recorded fatalities
  • 5-year trend+49%

What the CPSC Data Shows

Across the 20-year NEISS window from 2005 to 2024, injury counts for lye are rising by about 49% over the last five years, with the busiest year on record being 2005 (564 estimated ER visits) and the quietest 2013 (92 estimated visits). The single most common ER diagnosis is poisoning to the all parts body, accounting for approximately 1,386 visits across the 20-year NEISS window, followed by burn, chemical to the face (781 cases). The 0-4 age group absorbs the largest share of injuries, about 1,285 cases over the NEISS window, and males appear slightly more often than the opposite sex in that cohort. Severity outcomes from the NEISS disposition field show that 21.8% of ER visits involving this product end in hospital admission or transfer.

Beyond the hospital-sampled NEISS projections, this page also aggregates 2 consumer incident reports filed directly on SaferProducts.gov, plus 20 anonymized ER narratives - together forming a layered picture of how lye fail in real households. Every figure on this page comes from CPSC-published data: NEISS projects national estimates from a probability sample of about 100 U.S. hospital emergency departments, while SaferProducts.gov collects voluntary reports from consumers, manufacturers, and clinicians. The danger score, trend indicators, and demographic breakdowns update automatically when CPSC releases a new yearly NEISS file, which is why this page is dated 2024-12-31.

Consumer Incident Reports

Reports filed by consumers on SaferProducts.gov.

8/8/2019 · Injury, Hospital Admission · Boyer Corporation · New Hampshire

A toddler got into his mother's soap making lye and burned his mouth, requiring general anesthesia. Luckily he'll be OK, but the container is not child-proofed.

3/21/2020 · Incident, No Injury · Boyer Corporation · Massachusetts

My son had a school project to create something, so he decided to make his own "natural" soap. The recipe we found online called for the use of lye. So we utilized it, following the directions on the package. We made ten different containers of soap, one to turn in as his project and the others to give out to family and friends. When we set the containers on the floor to settle the lye burned a whole through the containers and caused damage to my hardwood floors, eating the polyurethane and discoloring my floor.
