Description

Dimethyl Lauramide/Myristamide is a chemical compound used in various cosmetic and personal care products. It is derived from lauric and myristic acids, which are fatty acids commonly found in natural oils and fats. This compound is valued for its emollient and conditioning properties, enhancing the texture and performance of cosmetic formulations.

Chemical Composition and Structure

Dimethyl Lauramide/Myristamide consists of:

Dimethyl Lauramide: A derivative of lauric acid with two methyl groups attached, contributing to its emollient properties.
Dimethyl Myristamide: A derivative of myristic acid with two methyl groups attached, enhancing its conditioning effects.
Fatty Acid Derivatives: Both components are based on fatty acids, which help in moisturizing and softening the skin.
The chemical structure features amide bonds between the fatty acids and dimethyl groups, which influence its physical and chemical properties.

Physical Properties

Appearance: Typically a clear to pale yellow liquid or solid, depending on the specific formulation.
Odor: Generally neutral or mild, designed not to interfere with the product’s overall fragrance.
Solubility: Soluble in organic solvents; limited solubility in water.
pH: Typically neutral or slightly acidic.
Stability: Stable under normal storage conditions; should be kept away from direct sunlight and excessive heat.

Production Process

Synthesis: Dimethyl Lauramide/Myristamide is synthesized through a reaction between lauric/myristic acids and dimethylamine.
Purification: The synthesized product is purified to remove any residual reactants or impurities.
Formulation: The purified compound is incorporated into various cosmetic and personal care products.
Quality Control: The product undergoes testing to ensure purity, consistency, and compliance with quality standards.

Applications

Cosmetics: Used as an emollient and conditioning agent in skincare and beauty products to improve texture and moisture retention.
Personal Care: Incorporated into body care and hair care products for its moisturizing and conditioning properties.

Environmental and Safety Considerations

Dimethyl Lauramide/Myristamide is generally considered safe for use in cosmetic and personal care products when used according to recommended guidelines. Individuals with sensitive skin or allergies should use it with caution. The production process should ensure that the compound is free from contaminants and produced in an environmentally responsible manner.

INCI Functions:


Surfactant - Emulsifying agent. Emulsions are thermodynamically unstable and are used to soothe or soften the skin and emulsify, so they need a specific, stabilising ingredient. This ingredient forms a film, lowers the surface tension and makes two immiscible liquids miscible. A very important factor affecting the stability of the emulsion is the amount of the emulsifying agent. Emulsifiers have the property of reducing the oil/water or water/oil interfacial tension, improving the stability of the emulsion and also directly influencing the stability, sensory properties and surface tension of sunscreens by modulating the filmometric performance.

Surfactant - Foam booster. It has the effect of introducing gas bubbles into the water and affects the cleaning process by helping to spread the cleanser. Since sebum has an inhibiting effect on the bubble, more foam is produced in the second shampoo.

Solvent. It is the substance for dissolving or dispersing surfactants, oils, dyes, flavourings, bactericidal preservatives in solution.In fact, it dissolves other components present in a cosmetic formulation. Solvents are generally liquid (aqueous and non-aqueous).

Surfactant - Cleansing agent. Cosmetic products used to cleanse the skin utilise the surface-active action that produces a lowering of the surface tension of the stratum corneum, facilitating the removal of dirt and impurities.
