Study Notes
Soap and Detergent Industry
- The soap and detergent industry primarily manufactures soap, synthetic organic detergents, inorganic alkaline detergents, and crude and refined glycerin from vegetable oils and animal fats.
Brief History of Soap and Detergent Industry
- Soap-like material was first inscribed on cylinders in 2800 BC (Babylonians).
- Egyptians used urine as a source of alkalinity in soap production in 1500 BC.
- Romans used soap-like material for treating skin diseases and washing in 300 BC.
- Soap-making became a commercial industry in Italy, Spain, and France in the 7th century.
- French chemist Nicholas Leblanc patented a process for making soda ash from common salt in 1791.
- Soap was heavily taxed as a luxury item in the 19th century.
- American Cleaning Institute was founded in 1926, and three firms dominated the industry: Colgate-Palmolive, Peet Inc., Lever Brothers, and Procter and Gamble.
Raw Materials
- Soap is manufactured from alkali (lye) and animal fats (tallow), which can be substituted with vegetable oil.
- Tallow is a by-product of slaughtering animals for meat or from whaling.
- Lye is obtained from wood ashes.
- Oil depends on the desired properties of the soap, such as coconut oil for hard soaps and olive oil for gentle and moisturizing soap.
Manufacturing Process for Soap
- Saponification: hydrolysis of triglycerides (fats) using a strong base such as NaOH.
- Neutralization: addition of alkaline solution to create a strong alkaline solution.
- Addition of additives: mixing in ingredients for desired soap properties.
- Molding and shaping: forming soap into desired shapes.
- Curing and drying: allowing soap to harden and dry.
- Packaging and distribution: preparing soap for market.
Manufacturing Process for Detergent
- Sulfonation: treating linear alkyl benzene (LAB) with sulfuric acid to produce linear alkyl benzene sulfonic acid (LABSA).
- Neutralization: adding a base, such as sodium hydroxide, to form the sodium salt of linear alkyl benzene sulfonate (LAS).
- Addition of builders and additives: adding ingredients to enhance cleaning performance and other properties.
- Spray drying or granulation: forming solid particles.
- Cooling and screening: removing oversized or undersized particles for uniform particle size.
- Packaging and distribution: preparing detergent for market.
Types of Detergent
- Anionic detergents: contain negatively charged heads, typically used in laundry detergents and dishwashing liquids.
- Non-ionic detergents: contain partially charged heads, typically used in front-loading washing machines and dishwashers.
Market Players
- Global market players: P&G, Unilever, and Johnson & Johnson.
- Philippine market players: various local companies.
Applications
- Soap: personal hygiene, laundry, cleaning surfaces.
- Detergent: industrial cleaning, laundry, specialized cleaning, dishwashing, institutional and commercial cleaning, vehicle cleaning.
Waste Treatment
- Wastewater treatment: flotation or foam separation to remove fatty acids and colloidal materials.
