Ingredients Overview
Ingredients List
Aqua (Purified Water), Sodium Hyaluronate (Plant Derived Molecule), Benzyl Alcohol, Dehydroacetic Acid
Key Ingredients
Low-weight-Hyaluronan, Medium-weight-Hyaluronan, High-weight-Hyaluronan
Ingredients Details
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.

Dehydroacetic Acid
Common Name(s): Dha preservative,3-acetyl-6-methyl-2h-pyran-2,4(3h)-dione
CAS Number: 520-45-6
DESCRIPTION
What It Does: Provides broad-spectrum preservation effective at higher ph than benzoate or sorbate.
Why It's Used: Ph-flexible preservative for formulations at ph 5-7 where sodium benzoate and potassium sorbate lose efficacy.
How It Works: Cyclic dicarbonyl pyranone structure provides ph-independent antimicrobial activity (active form is the neutral molecule, not ph-dependent ionisation). effective ph 4-8 (much broader than benzoate/sorbate). good antifungal vs aspergillus and candida. often used as sodium salt (sodium dehydroacetate) for water solubility.
Typically Found In: Higher ph cosmetics,anti-fungal preservation systems
TECHNICAL DETAILS
Primary Category: Functional ingredient โ pyranone preservative
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%โ0.6%
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: Eu max 0.6% as dehydroacetic acid. less commonly used than benzoate/sorbate due to higher cost.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Dehydroacetic acid's ph-independent antimicrobial activity arises from a fundamentally different mechanism vs benzoate/sorbate: rather than requiring the acidic free acid form (ph-dependent ionisation), dha's cyclic diketone structure is itself the active antimicrobial form. this means dha provides equivalent antimicrobial activity at ph 5 and ph 7 โ completely unlike the ph-sensitive preservatives that lose activity above ph 5.
