Gabatarwa zuwa Surfactants
Surfacts suna da tsarin samar da kwayoyin halittar kai tsaye: Aya'a daya ya ƙunshi ƙungiyar hydrophilic, yayin da kuma ƙarshen ƙarshen ya ƙunshi ƙungiyar hydrophobic, wanda aka sani da wutsiya na hydrophobic.

The hydrophilic group is often a polar group, which can be a carboxyl group (-COOH), a sulfonic acid group (-SO3H), an amino group (-NH2), amines and their salts, hydroxyl groups (-OH), amide groups, or ether linkages (-O-) as other examples of polar hydrophilic groups.
Kungiyar Hydrophobic yawanci sarkar Hydrocarbon, kamar ƙungiyoyi na alkyriphobic ko ƙungiyoyi masu ƙanshi (AR- don aryl).
