How surfactants work?
Surfactants are substances that improve the cleaning power of a detergent; these are molecules that have a hydrophilic part, which binds with water, and a part that mixes with fatty substances. In practice and referring for example to personal hygiene, surfactants help to remove particles of sebum, dust, etc. by binding to them and allowing them to be removed by rinsing.
Beware of these acronyms!
• Sodium Laureth Sulfate (SLES) e Sodium Lauryl Sulfate (SLS) are among the most widespread chemical surfactants… and potentially more irritating to skin and hair because they are definitely aggressive.
• Sodium coco sulfate, Sodium cocoyl hydrolyzed wheat protein, Coco glucoside, Disodium cocoyl glutamate etc. are naturally derived surfactants, respect the skin and its pH and have a very low impact on ecosystems.
