Cleaning Chemicals and Materials
Perhaps the most overlooked and common cause of foamy urine isn’t something that should cause concern. According to doctors, cleaning chemicals such as soap and other liquids can cause urine to foam due to its composition.
Cleaning products contain many compounds, including surfactants which are agents that decrease the surface tension of water. As a result, water molecules become more slippery, increasing their interaction rate with oil and grease. Surfactants are among the most versatile compounds in the industry because they’re amphiphilic molecules with both amphiphilic and hydrophilic parts.
Surfactants are also categorized into anionic and nonionic. Anionic surfactants are more common in cleaning agents and thus diffuse into the water. Due to their molecular nature, surfactants can trap pockets of gas on the surface of the liquids, which can appear foamy. If this is the cause of bubbly-looking urine, then there’s really no cause for concern.
