Science-based guidance for women for their bodies
The concept of internal menstrual absorption predates modern tampons by millennia. Archaeological evidence suggests that ancient Egyptian women used softened papyrus as internal menstrual products around 1500 BCE, while Roman women utilized wool tampons secured with string. These early innovations demonstrate humanity's long-standing recognition of the need for discrete, effective menstrual management.
The modern tampon emerged in 1929 when Dr. Earle Cleveland Haas, a general practitioner from Colorado, patented the first applicator tampon. His design featured compressed cotton with a cardboard applicator and removal string—innovations that remain fundamental to contemporary tampon design. Haas coined the term "tampon" from the French word "tampon," meaning plug or stopper.
Unable to find investors for his invention, Haas sold his patent to Gertrude Tendrich, a German immigrant who founded Tampax in 1936. The first mass-produced tampons were manufactured in Denver, Colorado, using compressed cotton and a cardboard applicator. By 1940, Tampax had established manufacturing facilities worldwide, making tampons globally accessible for the first time.
The 1970s marked a significant shift in tampon materials with the introduction of rayon (regenerated cellulose) and synthetic materials. These innovations promised higher absorption capacity and longer wear time. However, this period also coincided with the emergence of toxic shock syndrome (TSS) cases, leading to major regulatory and design changes.
Cotton remains the primary absorbent material in most tampons due to its natural absorbency, biocompatibility, and biodegradability. 100% cotton tampons absorb menstrual fluid through capillary action, drawing liquid into the cotton fiber matrix where it's held by surface tension and intermolecular forces.
Rayon, a regenerated cellulose fiber, offers superior absorption capacity compared to cotton alone. Most commercial tampons combine cotton and rayon in specific ratios to optimize absorption speed, capacity, and structural integrity. The smooth surface of rayon fibers allows for faster fluid uptake, while cotton provides bulk and retention.
100% Cotton: Natural, biodegradable, moderate absorption (6-9g capacity)
Cotton/Rayon Blend (50/50): Balanced absorption and retention (9-12g capacity)
Cotton/Rayon Blend (30/70): Maximum absorption, faster uptake (12-15g capacity)
Organic Cotton: Chemical-free, similar performance to conventional cotton
Cardboard applicators, introduced with the original Tampax design, remain popular due to their biodegradability and cost-effectiveness. Modern cardboard applicators feature smooth coatings and ergonomic designs to improve insertion comfort while maintaining environmental benefits.
Plastic applicators, typically made from polyethylene or polypropylene, offer smoother insertion and greater precision. Many feature rounded tips, anti-slip grips, and smooth gliding mechanisms. However, environmental concerns have led to increased development of biodegradable plastic alternatives.
Tampon absorption relies primarily on capillary action—the ability of liquid to flow through small spaces due to adhesive and cohesive forces. The fiber structure creates microscopic channels that draw menstrual fluid into the tampon core through surface tension and intermolecular attractions.
Tampon absorption follows predictable kinetic patterns. Initial uptake occurs rapidly (80% of capacity within first 15 minutes), followed by slower saturation completion. The absorption rate curve varies significantly between materials, with cotton/rayon blends showing optimal balance between speed and capacity.

Regulatory oversight through FDA ensures safety standards but allows higher absorption capacities than some regions.
European tampons often prioritize environmental sustainability with biodegradable applicators or applicator-free designs. Absorption capacities tend to be more conservative, with emphasis on frequent changing rather than extended wear. Organic cotton options are more prevalent, reflecting environmental consciousness.
Asian markets show preference for compact, discrete packaging and smaller applicator designs. Some regions emphasize preservation of hymen integrity, leading to specialized "virgin-friendly" designs with smaller diameters and more flexible materials. Cultural taboos influence marketing and availability.
Tampons are classified as Class II medical devices requiring 510(k) premarket notification. Manufacturers must demonstrate substantial equivalence to predicate devices and provide absorption capacity data. Labeling requirements include TSS warnings and usage instructions.
Under EU MDR 2017/745, tampons require CE marking and conformity assessment. Environmental regulations are stricter, encouraging biodegradable materials. Some countries have additional requirements for chemical testing and biocompatibility assessment.
Many developing countries lack specific tampon regulations, leading to quality variations and safety concerns. International aid organizations work to establish standards and improve access to safe menstrual products in these regions.
TSS results from Staphylococcus aureus toxin production when specific bacterial strains proliferate in high-oxygen environments created by super-absorbent tampons. The syndrome causes rapid onset of fever, hypotension, rash, and multi-organ dysfunction with potential fatal outcomes if untreated.
High-Risk Factors: Super-absorbent tampons, extended wear (>8 hours), continuous use during cycle
Prevention Strategies: Use lowest effective absorbency, change every 4-8 hours, alternate with pads, avoid overnight use exceeding 8 hours
Warning Signs: Sudden fever >102°F, vomiting, diarrhea, sunburn-like rash, dizziness
Approximately 2-5% of tampon users experience vaginal irritation, typically caused by fragrance, bleaching chemicals, or synthetic materials. Symptoms include itching, burning, unusual discharge, or contact dermatitis. Organic cotton tampons reduce but don't eliminate these reactions.
Recent research suggests that tampon use may temporarily alter vaginal microbiome composition, potentially affecting natural protective mechanisms. Studies show changes in Lactobacillus populations during tampon use, though clinical significance remains unclear.
Traditional chlorine bleaching of cotton and rayon can produce trace amounts of dioxin, a known carcinogen. Modern manufacturers use elemental chlorine-free (ECF) or totally chlorine-free (TCF) bleaching processes to eliminate dioxin formation while maintaining product whiteness and sterility.
Conventional cotton cultivation uses substantial pesticides, with potential residue presence in finished tampons. Independent testing has detected glyphosate residues in some conventional cotton tampons, leading to increased demand for organic alternatives certified by GOTS or USDA Organic standards.
Recent testing has identified trace amounts of heavy metals (lead, mercury, cadmium) in some tampon products, likely from environmental contamination of raw materials. Regulatory agencies are developing testing protocols and safety thresholds for these contaminants.
Studies show that tampon production generates 4.8-6.2 kg CO2 equivalent per woman per year, with plastic applicators contributing 40-50% of total emissions. Cotton cultivation accounts for 25-30% of emissions, while manufacturing and packaging represent 20-25%.
Globally, approximately 45 billion menstrual products are disposed of annually, with tampons representing 35-40% of this waste stream. In developed countries, tampons generate an average of 2.5-3.2 kg of waste per woman per year when including applicators and packaging.
