使い捨てウェットティッシュは生分解性か？

Based on general knowledge and the types of materials commonly used:

Generally, most standard disposable wipes (like baby wipes, cosmetic wipes, or surface cleaning wipes) are not biodegradable.

Here’s why:

1. Material Content: The majority of conventional wipes are made from nonwoven fabrics that blend natural fibers (like cellulose or cotton) with synthetic plastic fibers (such as polyester or polypropylene). These plastic components do not readily biodegrade and can persist in the environment for a very long time. Many disposable products utilise such non-biodegradable materials, including various non woven disposable cleaning wipes and items made clearly from plastics.
2. Persistence: While the natural fiber portion might break down eventually under the right conditions, the plastic fibers remain, fragmenting into microplastics rather than fully biodegrading.
3. Exceptions Exist: There are specific wipes on the market designed to be biodegradable or compostable. These are typically made entirely from plant-based materials like bamboo, cotton, or wood pulp (cellulose) and will be explicitly labelled as such. Meddisposable.json lists a 生分解性使い捨てシャワーキャップ as an example of a product specifically marketed with this property, highlighting that it’s not a default characteristic for all disposables.

Unless a wipe package explicitly states it is “biodegradable” (and preferably certified by a reputable standard), it is safest to assume it is not and should be disposed of in the trash, not composted or flushed.

The provided reference materials discuss writing style and contain no information about the biodegradability of disposable wipes.
