Role of Soyamide dea

Active Cosmetic Mechanisms

EMULSION STABILISING

Emulsion Stabilizer

Prevents oil and water mixtures from separating

SCIENTIFIC ANALYSIS

// Evidence: Emulsion stabilizers maintain dispersion of immiscible phases by preventing droplet coalescence through interfacial film formation, electrostatic repulsion, steric stabilization, viscosity enhancement, or network formation. Stabilizers include polymers (carbomers, xanthan gum), proteins, and modified celluloses. The combination of primary emulsifiers with secondary stabilizers creates robust lamellar liquid crystalline structures.

SURFACTANT - CLEANSING

Cleansing Surfactant

Removes dirt and oil through surfactant action

SCIENTIFIC ANALYSIS

// Evidence: Cleansing surfactants specifically formulated for removing sebum, dirt, and impurities. Primarily anionic (sodium laureth sulfate, sodium cocoyl isethionate) and amphoteric surfactants (betaines). Mechanism involves reducing surface tension enabling water to wet oily surfaces, solubilizing lipophilic materials in micelles, and emulsifying oils for rinse-off. Cleansing efficacy balanced with mildness by surfactant selection, concentration, and pH optimization. Must avoid excessive lipid removal that compromises barrier function.

SURFACTANT - EMULSIFYING

Emulsifying Surfactant

Blends oil and water phases into stable mixtures

SCIENTIFIC ANALYSIS

// Evidence: Emulsifying surfactants enable creation of stable oil-in-water or water-in-oil emulsions by positioning at oil-water interface, reducing interfacial tension. HLB (hydrophilic-lipophilic balance) determines emulsion type: HLB 3-6 for W/O, HLB 8-18 for O/W emulsions. Examples include polysorbate 80, ceteareth-20, glyceryl stearate. Mechanism involves forming interfacial film preventing droplet coalescence. Often used in combinations with co-emulsifiers (fatty alcohols) creating lamellar structures for enhanced stability.

SURFACTANT - FOAM BOOSTING

Foam Enhancer

Enhances foam quality and stability

SCIENTIFIC ANALYSIS

// Evidence: Foam-boosting surfactants enhance lather richness, bubble size, and foam stability when combined with primary foaming agents. Typically amphoteric surfactants (cocamidopropyl betaine) or alkanolamides (cocamide DEA, cocamide MEA). Mechanism involves increasing foam viscosity through synergistic interactions with anionic surfactants, stabilizing bubble films through mixed micelle formation, and reducing drainage rate. Result is creamier, longer-lasting foam improving sensory experience.

VISCOSITY CONTROLLING

Thickness Regulator

Adjusts product thickness and flow properties

SCIENTIFIC ANALYSIS

// Evidence: Viscosity controlling ingredients modify product flow characteristics through thickening or thinning. Thickeners include natural gums (xanthan, guar), synthetic polymers (carbomers, acrylates), and inorganic thickeners (silica, clays). Mechanism varies: polymer chain entanglement, hydrogen bonding networks, particle association, or swelling. Rheology modifiers create desired texture, prevent separation, control application properties, and affect sensory perception. Can produce Newtonian (constant viscosity) or non-Newtonian (shear-thinning, thixotropic) flow behavior.
