Here are some details on biodegradable materials commonly used in cheap sanitary pads:

Bamboo

Soft, sustainable fibers that are hypoallergenic. Absorbs well but pads may not feel as soft as more expensive brands.

Rayon/Viscose

Plant-based material that can break down but manufacturing releases toxic chemicals. Cheaper option.

Wheat/Corn Starch

Absorbs moisture well and is renewable but can attract insects if not composted properly.

Gel Binders

May be plant-based like potato starch or corn, but quality varies. Lower-end brands could use petroleum-based polymers.

Tissue Liners

Unbleached wood pulp is a sustainable option. Cheaper pads may use bright white bleached paper which is harsher.

Adhesives

Should be water-based and non-irritating. Check for harmful synthetic polymers or latex. Natural rubber is a better option.

Material Strength

Budget pads may feel thinner/weaker. Check they withstand normal activity without leaking or tearing.

Degradable Claims

True biodegradability requires commercial composting within 6 months, not just “oxo-degradable” or vague marketing terms.

Quality varies, so read ingredient labels carefully on affordable eco-friendly pads. Certification by groups like EU Ecolabel ensures biodegradability.
