What algae is in air freshener?

Some air fresheners contain extracts from algae, particularly those derived from the red algae species, like carrageenan. Carrageenan is often used as a thickening or stabilizing agent in various products, including air fresheners. It helps to create a gel-like consistency and can enhance the release of fragrance. However, not all air fresheners contain algae; it varies by brand and formulation.
