DESCRIPTION

What It Does: Provides humectant hydration and active ingredient solubilization with excellent skin feel.

Why It's Used: Preferred glycol humectant in premium and k-beauty formulations for superior skin feel vs propylene glycol with equivalent functionality.

How It Works: Two hydroxyl groups at 1,3-positions provide water binding and solvent activity. better tolerated than propylene glycol with minimal sensitization risk. 4-carbon backbone provides slightly greater hydrophobic character enabling dissolution of less polar actives vs pg.

Typically Found In: Toners,essences,serums,k-beauty formulas

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

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

Works Well With: Ceramides,emollients,occlusives,glycerin,hyaluronic acid

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

K-beauty's preference for butylene glycol over propylene glycol is driven by two factors: bg's superior skin feel (less tacky than pg's higher viscosity) and its lower sensitization potential (1,3-bg has better spatial distribution of hydroxyl groups that reduces protein interaction vs pg's 1,2-position oh groups).

DESCRIPTION

What It Does: Loosens corneocyte adhesion in the stratum corneum, accelerating cell turnover, refining skin texture, and improving radiance.

Why It's Used: Organic acids at cosmetic ph values provide controlled keratolytic exfoliation that improves skin texture, pore appearance, and radiance without mechanical irritation.

How It Works: At appropriate ph, the acid's undissociated form penetrates the stratum corneum and dissolves the ionic bonds between corneocyte desmosomes (calcium chelation mechanism), facilitating controlled desquamation and cell renewal.

Typically Found In: Toners,exfoliants,serums,peels,cleansers

TECHNICAL DETAILS

Primary Category: Exfoliants

Secondary Functions: Brightening,keratolytic

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 0.5–20%

SOURCING & ETHICS

Vegan Status: Yes

Halal Status: Yes

Source Notes: Synthetic or plant-derived acid; no animal components.

SKIN COMPATIBILITY

Irritancy Rating: 2

Comedogenicity Rating: 0

Sensitivity Concerns: May cause irritation or stinging in sensitive or barrier-compromised skin at high concentrations; patch test recommended.

Safe for Sensitive Skin: Conditional

SAFETY & COMPATIBILITY

Safety Profile: Safe within recommended ph and concentration ranges. sensitization risk increases above 10% aha. patch test recommended for sensitive skin. mildly irritating to some individuals at typical cosmetic use concentrations.

Works Well With: Niacinamide,hyaluronic acid,ceramides,vitamin c

Avoid Combining With: High concentrations on sensitive/broken skin; avoid with physical exfoliants

SCIENTIFIC NOTE

Cosmetic acids function at the pka boundary: only the undissociated acid (rcooh) penetrates the stratum corneum lipid barrier, while the ionized carboxylate (rcoo⁻) does not. the henderson-hasselbalch equation governs the fraction of active species at formulation ph; typically 0.5–3.0% undissociated acid provides efficacy while minimizing irritation.

DESCRIPTION

What It Does: Glycerin pulls water from the environment and deeper skin layers into the outer skin layer (epidermis), boosting moisture levels and keeping skin soft, smooth, and plump.

Why It's Used: It is used in virtually every moisturizer, serum, and cleanser because it is highly effective at hydrating skin, is well-tolerated by all skin types, and enhances the texture and spreadability of formulations.

How It Works: As a humectant, glycerin forms hydrogen bonds with water molecules, trapping them in the skin. it also reinforces the skin barrier by integrating into lipid structures between skin cells.

Typically Found In: Moisturizers,serums,cleansers,toners,sheet masks,sunscreens,body lotions,shampoos,conditioners

TECHNICAL DETAILS

Primary Category: Humectant

Secondary Functions: Skin barrier support,emollient,solvent

Application Areas:

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 1%–30% (typical: 3–10%)

SOURCING & ETHICS

Vegan Status: Yes – plant-derived (coconut, soy, palm) or synthetic

Halal Status: Yes – when plant-derived or synthetic; verify source with supplier

Source Notes: Derived from plant oils via hydrolysis or saponification; synthetic versions also available. palm-derived glycerin carries sustainability concerns.

SKIN COMPATIBILITY

Comedogenicity Rating: 0/5 – non-comedogenic

Sensitivity Concerns: Extremely rare allergic reactions; generally safe for all skin types including sensitive and baby skin

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Widely recognized as safe. ewg hazard score: 1. no significant concerns for irritation, sensitization, or toxicity at typical concentrations (up to 50%).

Works Well With: Hyaluronic acid,ceramides,niacinamide,panthenol,urea,peptides,retinol,ahas/bhas

Avoid Combining With: No known incompatibilities at standard concentrations

SCIENTIFIC NOTE

Glycerin is an endogenous skin component found naturally in the stratum corneum. aquaporin-3 channels in keratinocytes facilitate glycerin transport, making it integral to natural skin hydration pathways.

DESCRIPTION

What It Does: Provides humectant moisture retention with antimicrobial preservative-boosting activity.

Why It's Used: The balanced multifunctional diol — pentylene glycol provides the ideal balance of humectancy and antimicrobial activity for clean beauty preservation systems with excellent sensory compatibility.

How It Works: C5 diol: longer chain than propylene glycol providing better antimicrobial activity but shorter than 1,2-hexanediol (slightly lower membrane activity). two oh groups provide humectant water binding. solvent for fragrances and some actives. synergistic with phenoxyethanol reducing required phenoxyethanol concentration.

Typically Found In: Clean beauty products,natural preservation systems,moisturisers

TECHNICAL DETAILS

Primary Category: Functional ingredient – multifunctional pentanediol

Secondary Functions: Tewl reduction,skin plumping

Application Areas:

Typical Concentration Range: 0.5%–3%

SOURCING & ETHICS

SAFETY & COMPATIBILITY

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

Works Well With: Ceramides,emollients,occlusives,glycerin,hyaluronic acid

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Pentylene glycol's position in clean beauty preservation is due to a regulatory quirk: 1,2-pentanediol is not classified as a preservative in eu cosmetics regulations (unlike phenoxyethanol which requires preservative listing), so it can provide antimicrobial activity while not requiring the 'contains preservative' designation — enabling cleaner labels in natural-positioned formulations.
