Active Cosmetic Mechanisms
FRAGRANCE
Scent ProviderAdds pleasant scent to cosmetic products
SCIENTIFIC ANALYSIS
// Evidence: Fragrance ingredients provide aromatic appeal through essential oils, aroma chemicals, and natural extracts. These volatile compounds interact with olfactory receptors creating scent perception. Fragrance design considers top notes (high volatility), middle notes (moderate volatility), and base notes (low volatility) for scent development over time. Must consider stability, allergen content, and regulatory compliance.
OPACIFYING
Cloudiness CreatorReduces transparency and adds cloudiness to products
SCIENTIFIC ANALYSIS
// Evidence: Opacifying ingredients make formulations less clear through light scattering. These include titanium dioxide, zinc oxide, fatty alcohols, glycol stearates, and styrene/acrylates copolymer. The mechanism involves particles or crystalline structures that scatter light, reducing transmission and creating pearl-like or milky appearance. Particle size and refractive index determine degree of opacity. Used for aesthetic appeal and to mask colored ingredients.
PERFUMING
Fragrance ProviderProvides fragrance to enhance product appeal
SCIENTIFIC ANALYSIS
// Evidence: Perfuming ingredients add pleasant scents through complex mixtures of natural essential oils, aroma chemicals, and synthetic compounds. These volatile molecules evaporate and interact with olfactory receptors. Perfume construction uses top notes (citrus, herbs - high volatility), middle notes (floral, spice - moderate volatility), and base notes (woods, musks - low volatility) creating evolving scent profile. Must consider stability, allergen declaration, and IFRA compliance.
SURFACTANT - CLEANSING
Cleansing SurfactantRemoves 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.

What is Myristic Acid in skincare?
Myristic acid is a naturally occurring fatty acid found in foods like nutmeg, palm oil, coconut oil, and butter fat. It exists as a hard, white or faintly yellow crystalline solid or powder. It's also used in cosmetics and personal care products as various salts (such as Aluminum Dimyristate, Sodium Myristate) and esters (such as Butyl Myristate, Cetyl Myristate), which are created through reactions with bases and combining with alcohols.
What does Myristic Acid do? / Functions of Myristic Acid?
Common functions: FRAGRANCE, OPACIFYING, PERFUMING, SURFACTANT - CLEANSING.
What is the comedogenic rating of Myristic Acid? / Is Myristic Acid comedogenic?
Myristic Acid has a comedogenic rating of 4 out of 5. This ingredient appears to be comedogenic. A rating of 4 means it has high pore-clogging potential.
Does it clog pores?
This ingredient appears to be comedogenic (rating 4/5).
Is Myristic Acid safe for skin?
Myristic Acid has a safety rating of 2 out of 5. A rating of 2 means it is generally considered safe for most skin types.
Is Myristic Acid good for sensitive skin?
Myristic Acid has an irritancy rating of 3 out of 5. A rating of 3 means it may cause mild irritation for some.
What are the side effects of Myristic Acid in skincare?
Potential side effects include skin irritation (irritancy rating 3/5) and potential pore-clogging (comedogenic rating 4/5).
