Potassium Laurate 10124-65-9

Potassium Laurate (CAS Number: 10124-65-9) is the potassium salt of lauric acid, a fatty acid commonly derived from coconut oil or palm kernel oil. It has the chemical formula C₁₂H₂₃KO₂.

Key Information:

• Molecular Structure: Potassium Laurate consists of a long-chain alkyl group (laurate) attached to a potassium ion. The laurate group is derived from lauric acid, which is a 12-carbon saturated fatty acid.

• Appearance: Typically appears as a white or off-white powder or crystalline solid.

• Properties:

  • Solubility: It is soluble in water, forming an aqueous solution with emulsifying properties.
  • pH: Potassium Laurate is alkaline in nature, with a pH typically around 9–10 when dissolved in water.
  • Surfactant: It functions as an effective surfactant and emulsifier, meaning it can lower surface tension and help mix oil and water.

Applications:

• Surfactant: Used in personal care products (such as soaps and shampoos) for its cleansing and emulsifying properties.
• Cleaning Products: Employed in various detergents and cleaners.
• Cosmetic Industry: Acts as a stabilizer and emulsifier in creams, lotions, and other formulations.
• Lubricants and Greases: It can be used in lubricants due to its ability to interact with metal surfaces and reduce friction.
• Biodegradable: Being derived from natural fats and oils, it is biodegradable and environmentally friendly compared to synthetic surfactants.

Safety Considerations:

Potassium Laurate is generally considered safe in the concentrations typically used in products like soaps and shampoos. However, it can cause skin irritation in some individuals, especially in high concentrations, so it’s always important to follow recommended usage guidelines.

Chemical Reaction:

As a potassium salt, it may react with acids to form insoluble salts or with other surfactants to form complex formulations. In acidic environments, it may be converted to lauric acid, which is known for its antimicrobial properties.
