Overview of Mackamine LA
Mackamine LA is a surfactant with a chemical structure based on lauramine oxide, derived from coconut oil or palm kernel oil.
As a liquid at ambient temperature, it is a nonionic surfactant used primarily for its foam-boosting, foam-stabilizing, and emulsifying properties.
Lauramine oxide (C12H25NO) is an amine oxide compound, consisting of a nitrogen atom bonded to an alkyl chain (C12H25) and an oxygen atom.
It serves as a mild and effective ingredient in a variety of cleaning and personal care formulations.
Chemical Composition and Properties
Chemical Formula: Lauramine oxide, the active ingredient in Mackamine LA, has the formula C12H25NO, which means it contains one nitrogen atom, one oxygen atom, and a 12-carbon alkyl chain.
Appearance: Mackamine LA is typically a clear, viscous liquid at room temperature.
It is transparent to slightly hazy and should not become overly cloudy during storage at the recommended temperature.
Molecular Weight: The molecular weight of the lauramine oxide active ingredient is 240, which gives it its surfactant properties.
Its high molecular weight aids in its ability to stabilize foam in cleaning formulations.
pH Range: The pH of a 10% aqueous solution of Mackamine LA typically ranges from 7.0 to 9.0, making it relatively neutral to slightly alkaline.
This pH range ensures that it will not irritate most skin types or damage surfaces when included in formulations.
Solubility: Lauramine oxide is soluble in water, ethanol, and other organic solvents.
Its solubility and behavior in mixtures depend on the formulation, making it suitable for a variety of applications across diverse industries.
Stability: Mackamine LA is stable across a wide range of pH levels and temperatures.
It is resistant to degradation in the presence of bleach or other oxidative agents, making it ideal for use in household and industrial cleaning products.
Safety Profile: The product contains less than 1% free amine (C12H25NH2), which can be reactive under certain conditions, but it is typically not harmful in the concentrations used in products.
It is generally regarded as safe when used as intended.
Applications of Mackamine LA
Bleach Cleaners
Mackamine LA serves as a key ingredient in bleach-based cleaning products, especially those designed for hard surfaces.
In bleach cleaners, it enhances the foaming and wetting properties of the formula, allowing the active chlorine to work more effectively.
The presence of Mackamine® LA also ensures the formulation remains stable over time and does not degrade under harsh conditions.
Typical Concentration: 1-5%
Role in the Formula: Surfactant (foam boosting, emulsifying, and stabilizing).
Alkaline/Acid Cleaners
Mackamine LA is widely used in both alkaline and acid-based cleaners, which include degreasers, bathroom cleaners, and more.
Its mild nature and ability to function in extreme pH ranges (both high and low pH) make it a versatile additive in formulations. Additionally, it helps improve the product’s cleaning efficiency by enhancing foam generation and soil suspension.
Typical Concentration: 1-5%
Role in the Formula: Surfactant, wetting agent, foam stabilizer.
Liquid Dishwashers
Due to its gentle foaming properties and ability to produce long-lasting bubbles, Mackamine LA is a preferred ingredient in dishwashing liquids.
It enhances the viscosity of the product, helps with grease and oil emulsification, and supports longer-lasting foam, making dishwashing easier and more effective.
Typical Concentration: 5-10%
Role in the Formula: Surfactant (foam boosting, emulsification, grease removal).
Shampoos and Personal Care Products
Mackamine LA is also used in personal care products like shampoos, body washes, and facial cleansers.
Its mild surfactant properties make it ideal for use on the skin and scalp, providing gentle cleansing without stripping natural oils.
It also enhances the sensory profile of products by stabilizing foam, contributing to a rich lather experience.
Typical Concentration: 5-10%
Role in the Formula: Surfactant, foaming agent, mild cleansing agent.
3.5 Skin Cleansers
In skin cleansers, Mackamine LA’s ability to provide gentle, non-irritating cleansing and foam stabilization makes it suitable for sensitive skin formulas.
It works by reducing the surface tension of the skin and the product, allowing it to clean more efficiently without excessive dryness or irritation.
Typical Concentration: 5-10%
Role in the Formula: Surfactant, foam stabilizer, mild cleansing.
Storage and Handling
Mackamine LA should be stored in sealed containers to protect it from contamination and to maintain its stability.
The product should be kept in a dry, cool place away from direct sunlight, ideally in temperatures below 30°C.
If the product appears cloudy after exposure to cold temperatures, it can be gently warmed to around 35°C to restore its clarity, followed by thorough mixing.
Ideal Storage Temperature: Below 30°C
Handling Temperature: 25°C to 45°C
Freezing Point: Mackamine® LA should not freeze, as this may affect its effectiveness.
