Kose Cosmeport Softymo Cleansing Foam White 190G

DESCRIPTION

What It Does: Provides antimicrobial c12 fatty acid activity against p. acnes and skin pathogens alongside emollient conditioning.

Why It's Used: Antimicrobial emollient with documented anti-acne activity through p. acnes membrane disruption – the primary antimicrobial fatty acid in human breast milk and coconut oil.

How It Works: C12 chain length is optimal for antimicrobial fatty acid activity: long enough for membrane insertion but short enough for effective disruption. disrupts p. acnes lipid membrane. converts to monolaurin (antimicrobial monoglyceride) via skin esterases. low melting point (44°c) provides liquid-phase emolliency above skin temperature.

Typically Found In: Anti-acne products,antimicrobial skin care,coconut-based products

SCIENTIFIC NOTE

Lauric acid's antimicrobial activity against p. acnes (ic50 ~1μg/ml) exceeds benzoyl peroxide's ic50 (~50μg/ml) by approximately 50-fold in in vitro studies, making it one of the most potent naturally occurring anti-p. acnes compounds. its high comedogenicity rating (4/5) presents the paradox of a powerful anti-acne active in a comedogenic vehicle – limiting its practical anti-acne formulation use.

DESCRIPTION

What It Does: Deposits a smooth, glossy film on skin and hair providing moisture retention from the high serine/glycine hygroscopic amino acid content, reduces surface friction, and provides skin conditioning through the protein film's structural properties.

Why It's Used: Silk protein provides the unique 'silky smooth' texture that synthetic polymers cannot fully replicate — the specific amino acid ratios of natural silk fibroin and sericin creating a film with genuine silk-like gloss and smoothness.

How It Works: Silk fibroin's β-sheet crystalline domains (high glycine-alanine-serine content) provide film tensile strength; amorphous regions provide flexibility. sericin (mw 10–300 kda) adsorbs onto skin and hair surfaces through h-bonding from its high serine oh content. the film's protein structure provides breathability absent from synthetic polymer films.

Typically Found In: Luxury skin care,hair conditioning,silk products

SCIENTIFIC NOTE

Sericin's amino acid composition is 33% serine — the highest serine content of any commercial protein. serine's β-hydroxyl group provides exceptional moisture-binding capacity (3 h-bonds per residue) explaining sericin's superior humectant conditioning versus lower-serine proteins.

DESCRIPTION

What It Does: Provides fatty acid thickening and emolliency with soap-forming emulsification when neutralized.

Why It's Used: Classic cosmetic fatty acid used in virtually all cream and lotion formulations for thickening, emolliency, and opacification.

How It Works: Forms metal soaps (sodium stearate, potassium stearate) on reaction with alkalis for self-emulsification. crystallizes in lamellar networks for thickening. waxy solid provides opacification. low-viscosity melt above 69°c for easy processing.

Typically Found In: Creams,soaps,cleansers,emulsions – foundational ingredient

Typical Concentration Range: 1%–15%

SOURCING & ETHICS

Vegan Status: Yes – from vegetable (palm, shea, soy stearin)

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Excellent safety profile. ewg score: 1.

Works Well With: Humectants,ceramides,actives as carrier

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Stearic acid's dual role as both an emulsifier precursor (when saponified to sodium stearate soap) and an emollient (as unmodified fatty acid) is unique among cosmetic fatty acids. in soap-based cleansers, stearic acid is intentionally partially saponified to create a balanced system: excess stearic acid provides skin-conditioning emolliency while the sodium stearate provides surfactancy – the chemical basis for 'superfatted' soaps.
