Seventh Generation Regular Tampons
Lower concern, though brand opacity limits full confidence.
Seventh Generation Regular Tampons use bleached rayon and cotton that don't require PFAS-based water repellents. The brand does not disclose PFAS-avoidance efforts or provide independent lab testing.

What Seventh Generation Regular Tampons is made of, ingredients and materials
These tampons use viscose (regenerated cellulose) as the core absorbent material, which is bleached during manufacturing. The applicator is cardboard-wrapped cotton. Viscose is derived from wood pulp treated with sodium hydroxide and carbon disulfide; the bleaching step historically used chlorine, though modern processes have shifted toward oxygen-based alternatives. Rayon/viscose itself is not inherently toxic once the garment or product reaches the consumer, but the manufacturing process carries occupational and environmental concerns that don't directly affect the end user's safety.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Dioxins from bleaching (historical concern)
Chlorine bleaching of rayon can theoretically produce trace dioxins; Seventh Generation markets 'chlorine-free' bleached products, suggesting oxygen-based bleaching. No dioxin testing results are publicly available for this product. Modern bleaching practices in developed manufacturing have substantially reduced dioxin risk compared to 1980s-1990s production.
Bacterial or fungal contamination during storage or manufacturing
Tampons are sterile-packaged single-use products; contamination risk is low if packaging is intact and storage conditions are dry. No recalls for microbial contamination of Seventh Generation tampons are on record. Risk increases only if packaging is damaged or tampons are stored in humid environments before use.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Residual sodium hydroxide or carbon disulfide (viscose processing)
These chemicals are used to dissolve wood pulp during viscose fiber creation but are largely removed and recovered in closed-loop manufacturing. No residual exposure to the consumer is documented or expected from finished tampons. Occupational exposure during manufacturing is the primary concern, not product use.
Rayon fiber shedding or microfiber retention
Viscose rayon fibers can shed or fragment during use; no evidence of clinically significant microfiber lodgment or inflammation in vaginal tissue from tampon use is documented. This remains a theoretical concern without established harm in published literature.
Allergic sensitization to fragrance or additives (if scented variants)
Seventh Generation Regular Tampons are unscented; fragranced tampons in general carry low documented sensitization risk but are not recommended by gynecologists. This product avoids that hazard category entirely.
How is this PFAS grade calculated?
The brand's record and disclosure
Seventh Generation publishes ingredient lists for tampons more transparently than many competitors and markets itself as chlorine-free bleached. The brand does not independently certify its tampons as organic (unlike some premium alternatives) and maintains limited third-party testing data in the public domain. No recalls or safety incidents involving this product line are on record. The brand's silence on PFAS testing is consistent with the industry baseline; most tampon manufacturers do not disclose PFAS testing, though the fibrous nature of tampons makes intentional PFAS treatment unnecessary.
How it compares in its category
Standard rayon-based tampons dominate the market and carry the same chemistry profile as Seventh Generation's offering. Organic cotton alternatives (100% cotton or cotton-rayon blends) command premium pricing with marginal safety difference for typical users. Fully synthetic polymer tampons (rare) would pose different trade-offs. Seventh Generation's positioning, chlorine-free bleached viscose at mainstream price, represents a middle ground between conventional bleached rayon and certified organic cotton options.
If you buy it
Use as directed; tampons are single-use internal menstrual products and require no special maintenance. Replace every 4-8 hours to reduce toxic shock syndrome risk, regardless of brand. Store in cool, dry conditions; moisture exposure can promote mold or bacterial growth before use. No heating, microwaving, or reuse. Discontinue and consult a healthcare provider if you experience irritation, unusual odor, or symptoms of infection.
