Soaps are an example of biodegradable, but other detergents are not an example of biodegradable. Soaps are long-chain sodium salts of carboxylic acids. Detergents are long-chain benzene sulphonic acid’s sodium salts. Soaps have a modest wiping effect. but detergents have an intense cleaning activity.
Triglycerides are fat or oil molecules composed of glycerin chemically linked to three fatty acids. Soaps are surfactants, which means they dissolve in water and oils and can clean them. Preparation of soap includes reacting fats or oils with a solid hydroxide base to generate soap and glycerin.
Detergents
Detergent, also referred to as surfactants, are substances that can lower water’s surface tension. Detergents are compounds with the charged hydrophilic group at the end of lipophilic hydrocarbon groups. The head refers to the charged hydrophilic group. whereas the tail refers to the lengthy lipophilic hydrocarbon group.
Characteristics of Detergents
- The critical micelle concentration is the concentration at which micelles begin to form.
- The average number of monomers in a micelle is the aggregation number.
- Micelle molecular weight indicates relative micelle size.
- The cloud point is the temperature at which the detergent solution splits into two phases when it is above or around the critical micelle concentration.
Soaps
Soaps are essential for keeping people’s hygiene and health in line. Soap are used to clean, wash, and do other household activities.
- Soaps are the sodium (Na) or potassium (K) salts of a carboxylic acid-containing long aliphatic chain.
- Soaps are surfactant chemicals that help to emulsify oils in water by lowering the surface tension between a liquid and another substance.
- Saponification of fats and oils use to make soaps.
- The soap molecule’s carboxylate tail is hydrophilic. and the hydrocarbon tail is hydrophobic.
What is Saponification?
Soaps are long-chain fatty acid potassium or sodium salts. The method of obtaining soap is known as saponification. The ester interacts with an inorganic base to get alcohol and soap during saponification. In most cases. It happens when triglycerides react with potassium (K) or sodium (Na) hydroxide to form glycerol and salt of fatty acid known as soap.
Animal fats and vegetable oils are the most common sources of triglycerides. When they react with sodium hydroxide. They produce a complex form of soap. Potassium is added, resulting in a softer version of the soap. The resulted equation is written as,
Base + Ester → Soap + Alcohol
Alum Soap
Alum is a type of natural healer that may cure various skin wounds. On painful canker sores and broken heels. Alum soap is quite effective. Alum soap heals the wound and rejuvenates and restores the skin’s natural shine.
- It moisturises dry, cracked heels.
- It heals your skin’s damage.
- Alum soap effectively heals injuries on the skin while preventing infection.
- It also lifts, strengthens, tightens, and acts as a natural cleanser.
What is Micelle?
The soap molecule arrang uniquely in water, which aids to maintain the hydrocarbon part out of the H2O (water).
- When molecules form, the hydrophobic tail emerges from the cluster’s center, and the ionic end comes from the cluster’s surface, creating a micelle.
- When soap is in micelles. It can wipe the sticky dirt that accumulates in the center.
- These micelles continue to exist as colloidal solutions.
- As a result, the dirt on the cloth read remove. Because the soap solution forms a colloidal solution that scatters light, it appears cloudy.
