DESCRIPTION

What It Does: Prevents microbial contamination that would otherwise render water-containing cosmetics unsafe — inhibiting bacterial, fungal, and yeast growth through membrane disruption, enzyme inhibition, or metabolic interference at permitted regulatory concentrations.

Why It's Used: Preservatives are safety-critical — un-preserved water-containing cosmetics can develop dangerous microbial contamination (pseudomonas aeruginosa eye infections, s. aureus skin infections) within days. preservation is a regulatory requirement, not an optional enhancement.

How It Works: Mechanism varies by class: organic acids (benzoic, dehydroacetic) disrupt intracellular ph in bacteria and fungi by proton flux across membranes; parabens inhibit membrane-associated enzyme function; chlorhexidine disrupts bacterial and fungal membrane integrity through divalent ion chelation of membrane phospholipids.

DESCRIPTION

What It Does: Provides co-solvent and penetration enhancer in cosmetic formulations, improving active ingredient dissolution and product texture while delivering mild skin conditioning.

Why It's Used: Glycol solvents are essential for dissolving actives with limited water or oil solubility — the intermediate polarity of glycol ethers provides access to the wider solubility parameter space between pure water and oil phases.

How It Works: Hydroxyl and ether groups provide h-bonding for water miscibility; the organic chain provides compatibility with lipophilic actives. medium-chain glycols (c3–c6) provide the optimal balance of water compatibility, lipophilic active dissolution, and skin-compatible humectancy.

Typically Found In: Skin care formulations,co-solvent systems

DESCRIPTION

What It Does: Panthenol deeply moisturizes skin and hair, soothes irritation, accelerates wound healing, strengthens the skin barrier, and improves hair elasticity and shine.

Why It's Used: It is used because it is exceptionally versatile, working in both skin and hair formulations. it is gentle enough for sensitive and post-procedure skin, and converts to the active vitamin b5 within the skin.

How It Works: Panthenol penetrates skin and hair, where it is oxidized to pantothenic acid (vitamin b5), a coenzyme a precursor essential to metabolism. in skin, it acts as a humectant and stimulates fibroblast proliferation. in hair, it coats the shaft, improving manageability.

Typically Found In: Moisturizers,serums,toners,after-sun products,wound healing products,shampoos,conditioners,hair masks,beard care

TECHNICAL DETAILS

Primary Category: Active ingredient – provitamin b5

Secondary Functions: Anti-inflammatory,wound healing,hair conditioning

DESCRIPTION

What It Does: Solubilizes fragrance oils and other lipophilic ingredients into water-based formulations.

Why It's Used: Standard fragrance solubilizer for water-based formulations – the industry standard for incorporating oil-soluble fragrances and actives into aqueous systems without separate oil phase.

How It Works: Hlb ~16.7 provides strong solubilization capacity for oils in water. laurate (c12) chain provides milder skin interaction than higher-hlb polysorbates. polyoxyethylene chains (20 eo units) provide high water solubility. effective solubilizer at 3-4:1 polysorbate:fragrance ratio.

Typically Found In: Toners,micellar waters,fragrance-containing aqueous products

SAFETY & COMPATIBILITY

Safety Profile: Same peg 1,4-dioxane concern as all peg compounds. quality-grade ps-20 should be tested for impurities.

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Polysorbate 20's optimal solubilization ratio (3-4 parts ps-20 per part fragrance oil) is lower than expected from pure hlb theory. this efficiency arises from polysorbate's formation of very small, stable oil-in-water microemulsions (droplets <50nm) rather than conventional emulsions, providing optically clear, thermodynamically stable fragrance incorporation that conventional emulsifiers cannot achieve.

Primary Sources: 2026-03-12

DESCRIPTION

What It Does: Salicylic acid exfoliates the skin surface and inside pores, dissolves the 'glue' holding dead skin cells together, reduces sebum production, and combats acne-causing bacteria.

Why It's Used: Its oil solubility makes it uniquely effective at penetrating pores and dissolving sebum plugs – a function that water-soluble ahas cannot perform. it is the preferred exfoliant for oily, acne-prone, and congested skin.

How It Works: Salicylic acid disrupts desmosomal bonds between corneocytes, promoting exfoliation. its oil solubility allows it to penetrate the sebaceous follicle, dissolving sebum and dead cells. it also has anti-inflammatory properties by inhibiting prostaglandin synthesis.
