Study Notes
Soap Making
- Deodorization is a process in soap making that removes impurities and odor from the soap.
- Saponification occurs in the step where fats or oils react with an alkali to produce soap and glycerine.
- The cold process method involves reaching trace before pouring into molds for curing.
Properties of Oils
- Olive oil is known for producing a thick lather and hydrating the skin in soap-making.
- Flaxseed oil enriches soap with omega-3 fatty acids, providing moisturizing properties.
- Palm oil is a fundamental ingredient that imparts hardness and stability to soap bars.
Functions of Ingredients
- Sodium hydroxide or potassium hydroxide are used to catalyze the saponification reaction.
- The function of additives is to enhance the soap's texture, appearance, and performance.
Detergent Making
- The refining step involves removing impurities like free fatty acids and metals.
- The finishing step 5 in the detergent making process involves packaging and labeling.
- Surfactants are hazardous because they can bioaccumulate and harm aquatic life.
- Phosphates impact aquatic life by promoting algal blooms, which deplete oxygen and harm aquatic life.
- The screening process is a physical treatment in wastewater treatment that removes large objects.
- Activated carbon adsorption is a treatment that removes impurities and odors from wastewater.
- Formaldehyde and ammonium sulfate are used as preservatives and anti-caking agents in detergent making.
- Surfactants play a crucial role in cleaning detergents by reducing the surface tension of water.
Enzymes
- The primary function of catalytic enzymes in detergent formulations is to break down protein, lipid, and polysaccharide soils.
- Alkalis are added to detergent production to increase the pH and enhance the enzyme's activity.
- Proteases are commonly used to remove protein soils from dishes.
- The most widely used detergent enzymes are proteases, lipases, and amylases.
History
- The ancient Babylonians were credited with inventing soap first, based on the earliest record of it.
- The process of making soap is called saponification.
- The two main products of saponification are soap and glycerine.
Miscellaneous
- The surfactant that mainly causes algal bloom is sodium lauryl sulfate.
Learn about the final step in the soap making process where the continuous soap ribbon is cut into individual bars or shapes, packaged and prepared for distribution and sale. Understand the significance of raw materials like detergent surfactants and alkalies in the soap making process.
