Sodium salts of fatty acids.<\/p>\n<p>Detergents are anionic surfactants, which means they have a negatively charged end and a positively charged end. The negatively charged end of the detergent molecule is attracted to water, while the positively charged end is attracted to oil and grease. This allows detergents to break down and remove dirt and grime from surfaces.<\/p>\n<p>Sodium salts of fatty acids are the most common type of detergent. They are made by reacting sodium hydroxide (lye) with fatty acids, which are found in animal and vegetable <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> oils.
