Inertia Launches Eco-Friendly Feminine Pads with Bio-Based Core in the U.S.

Inertia Introduces Feminine Pads with Bio-Based Core in the U.S.

The South Korean femtech brand Inertia officially entered the United States market with the launch of its innovative feminine hygiene pads. These products feature a proprietary, bio-based core designed to replace the synthetic superabsorbent polymers (SAP) traditionally found in conventional sanitary napkins.

Key Product Features

The launch of Prism Pads signifies a shift toward bio-based alternatives, utilizing Inertia's Labocell technology, which employs a cellulose-derived matrix to provide superior, flexible, and breathable absorbency. In developing Prism Pads, Inertia aimed to revolutionize both material transparency and absorbent efficacy. According to Kim, the pads are engineered with organic cotton nonwoven materials across critical components, specifically the cover and wings, ensuring that all surfaces directly contacting the body consist of natural fibers.

According to Towards Chemicals & Materials, the natural polymer market size accounted for USD 42.55 billion in 2025 and is predicted to increase from USD 45.8 billion in 2026 to approximately USD 88.92 billion by 2035, expanding at a CAGR of 7.65% from 2026 to 2035 as emphasis on sustainable and biodegradable products is rapidly increasing globally.

Shift from Petroleum-Based Products Accelerates the Natural Polymer Market
