Ingredients Details
Butylene Glycol
Common Name(s): 1,3-butanediol,bg,1,3-butylene glycol
CAS Number: 107-88-0
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
TECHNICAL DETAILS
Primary Category: Functional ingredient โ glycol humectant
Secondary Functions: Tewl reduction,skin plumping
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ10%
SOURCING & ETHICS
Vegan Status: Yes โ synthetic
Halal Status: Yes
Source Notes: Synthetic or naturally derived. excellent aqueous solubility.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating; suitable for all skin types.
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).

Citric Acid
Common Name(s): Lemon acid,2-hydroxypropane-1,2,3-tricarboxylic acid
CAS Number: 77-92-9
DESCRIPTION
What It Does: Adjusts ph to optimal ranges, chelates destabilizing metal ions, provides mild exfoliation at higher concentrations.
Why It's Used: Universal cosmetic ph adjuster and chelating agent. aha exfoliant activity is secondary.
How It Works: As ph adjuster, donates protons. as chelating agent, three carboxylic groups bind divalent metals (caยฒโบ, mgยฒโบ, feยฒโบ) preventing oxidative degradation.
Typically Found In: Nearly all cosmetic formulations,brightening products,exfoliants
TECHNICAL DETAILS
Primary Category: Active ingredient โ alpha hydroxy acid (aha)
Secondary Functions: Chelating agent,ph adjustment,preservation enhancement
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%โ10%
SOURCING & ETHICS
Vegan Status: Yes โ synthetic or fermentation-derived
Halal Status: Yes
Source Notes: Produced by fermentation of sugars by aspergillus niger. gras (e330). most abundant organic acid in citrus.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low at low concentrations; 2/5 at exfoliant concentrations
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Photosensitizing โ mandatory spf use. start at low frequency.
Safe for Sensitive Skin: Use with caution โ spf required
SAFETY & COMPATIBILITY
Safety Profile: Safe at otc concentrations. eu: โค10% leave-on at ph โฅ3.5. mandatory spf advisory.
Works Well With: Niacinamide,ceramides,hyaluronic acid,spf
Avoid Combining With: Retinol in same step; multiple exfoliants simultaneously
SCIENTIFIC NOTE
Three carboxylic acid groups provide multiple proton donation sites and stronger chelation than monocarboxylic ahas. this makes citric acid the preferred cosmetic chelating agent alongside edta.

Glycerin
Common Name(s): Glycerol,glycerine,1,2,3-propanetriol
CAS Number: 56-81-5
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:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ30% (typical: 3โ10%)
SOURCING & ETHICS
Vegan Status: Yes โ plant-derived (coconut, soy, palm) or synthetic
Halal Status: Yes โ 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
Irritancy Rating: 1/5 โ very low; non-irritating at all standard concentrations
Comedogenicity Rating: 0/5 โ 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.

Peg-40 Hydrogenated Castor Oil
Common Name(s): Peg-based nonionic emulsifier,ethoxylate surfactant,o/w solubiliser
CAS Number: N/a
DESCRIPTION
What It Does: Stabilises o/w emulsions by reducing interfacial tension, solubilises oils and fragrances in aqueous systems, and wets oil-phase components for improved formulation homogeneity.
Why It's Used: Peg emulsifiers are selected for their precise hlb, broad ph stability (unlike soap emulsifiers that lose function at acidic ph), and compatibility with both anionic and cationic co-ingredients in the formulation system.
How It Works: Peg chain length determines hlb: longer peg = higher hlb = more hydrophilic = better o/w emulsification. at the o/w interface, the peg chain extends into the water phase forming a hydrated steric barrier that prevents droplet coalescence. nonionic character provides ph-independent function across the full cosmetic ph range.
Typically Found In: Emulsions,fragrance solubilisation
TECHNICAL DETAILS
Primary Category: Active ingredient โ cosmetic active
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ10%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Well-tolerated by most skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Good safety profile at recommended concentrations. ewg score: 1โ2.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Mixed peg emulsifier systems (e.g., peg-100 stearate + glyceryl stearate) form more cohesive interfacial films than single emulsifiers โ the geometric complementarity of the co-emulsifier pair providing better mechanical emulsion stability than either component alone.
