Benzyl Alcohol
Common Name(s): Phenylcarbinol,benzenemethanol,alpha-hydroxytoluene
CAS Number: 100-51-6
DESCRIPTION
What It Does: Provides dual fragrance and preservative activity as an aromatic alcohol.
Why It's Used: Multi-function ingredient serving as both fragrance component and preservative โ reduces formulation complexity by providing both functions in one ingredient.
How It Works: Phenylcarbinol provides antimicrobial activity via membrane disruption (effective vs gram-positive bacteria and moulds). solvent for fragrances and difficult-to-dissolve actives. mild oxidative conversion to benzaldehyde provides sweet almond-like fragrance.
Typically Found In: Fragrances,preserved cosmetics,solvent systems
TECHNICAL DETAILS
Primary Category: Fragrance component / preservative
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.001%โ1% (fragrance); up to 1% as preservative
SOURCING & ETHICS
Vegan Status: Yes โ from toluene, or jasmine absolute
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: Eu cosmetics regulation: declared fragrance allergen. also listed as approved preservative (annex v, max 1%). dual regulatory status (fragrance + preservative) depending on function and concentration.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Benzyl alcohol's dual regulatory status (fragrance allergen and approved preservative) creates a formulation paradox: it must be listed as a fragrance allergen if present >0.001% (leave-on) regardless of whether it was added for fragrance or preservation. this regulatory dual identity means a preservative added for antimicrobial function triggers the same allergen declaration requirement as a fragrance added for scent.

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.

Disodium Edta
Common Name(s): Edathamil disodium,edta disodium,versene 100
CAS Number: 139-33-3
DESCRIPTION
What It Does: Provides metal ion chelation to prevent product degradation and boost preservative and antioxidant efficacy.
Why It's Used: The most essential stability ingredient in cosmetics โ disodium edta's metal chelation prevents rancidity, discoloration, and preservative failure caused by trace metal contamination in virtually all aqueous cosmetic formulations.
How It Works: Ethylenediaminetetraacetic acid provides six potential coordination sites for metal ions (aminodiacetate groups). chelates caยฒโบ, mgยฒโบ (stability), feยณโบ (fenton radical prevention), cuยฒโบ (oxidase inhibition). disrupts gram-negative bacterial outer membrane by chelating membrane calcium, enhancing preservative penetration.
Typically Found In: Virtually all aqueous cosmetics โ creams, lotions, shampoos, toners
TECHNICAL DETAILS
Primary Category: Functional ingredient โ chelating agent
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.005%โ0.1%
SOURCING & ETHICS
Vegan Status: Yes โ synthetic
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
Disodium edta's preservative potentiation against gram-negative bacteria is mechanistically elegant: gram-negative outer membranes contain lipopolysaccharide stabilised by calcium and magnesium bridges. edta chelates these metal ions, destabilising the lps layer and creating pores that allow hydrophobic preservatives (phenoxyethanol, parabens) to penetrate โ converting gram-negative-resistant preservatives into broad-spectrum ones.
