Laundry detergent pods are convenient, single-dose capsules encased in a water-soluble film, releasing concentrated detergent and cleaning agents during washing. Their concentrated formula works in cold water, saving energy and time. Proper use ensures effective cleaning, while safety measures protect against ingestion and irritation risks. Though environmentally better in use, the pod film's biodegradability remains a challenge. Advances continue to improve performance and sustainability for future laundry needs.
