Where these two actually differ
- We flag Azo dyes and colorfast residues, Formaldehyde resins in fabric finishes, Microplastic shedding during laundering and Allergic contact dermatitis from residual chemicals on the The Period Company and not on the Ruby Love.
- We flag Coating degradation and microparticle shedding and Bacterial or fungal growth if improperly stored on the Ruby Love and not on the The Period Company.
- The The Period Company is cotton blend, absorbent core where the Ruby Love is organic cotton, waterproof backing layer, which is most of the difference in these two grades.
- The gap is 30 points, wide enough that this is not a close call, and the Ruby Love is the one to buy.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
