Ingredients Details
Benzophenone-3
Common Name(s): Oxybenzone,2-hydroxy-4-methoxybenzophenone,uva+uvb filter
CAS Number: 131-57-7
DESCRIPTION
What It Does: Provides combined uva and uvb filtration in a single chemical uv filter molecule.
Why It's Used: Combined uva+uvb filter historically used for broad-spectrum coverage in a single ingredient, now increasingly restricted.
How It Works: Benzophenone chromophore absorbs uvb (305nm) and uva-ii (326nm) via two separate nโฯ* transitions. water-soluble allows aqueous phase formulation. single filter providing partial broad-spectrum coverage.
Typically Found In: Sunscreens (being phased out in many markets)
TECHNICAL DETAILS
Primary Category: Active ingredient โ chemical uva/uvb filter
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: Up to 6% (eu), 6% (us fda)
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

SAFETY & COMPATIBILITY
Safety Profile: Eu max 6%. coral reef/aquatic toxicity โ banned hawaii, palau, some us states. potential endocrine activity at high systemic exposure. ewg score: 7. use declining due to regulatory pressure.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Benzophenone-3's declining use reflects evolving understanding of environmental and endocrine impacts: discovered in coral bleaching studies, its restriction in hawaii (2018) sparked a global trend in marine-safe sunscreen formulations that is reshaping the industry away from bp-3 toward mineral filters and marine-safer organic alternatives.

Phenoxyethanol
Common Name(s): 2-phenoxyethanol,rose ether,ethylene glycol monophenyl ether
CAS Number: 122-99-6
DESCRIPTION
What It Does: Prevents microbial contamination and spoilage in cosmetic formulations.
Why It's Used: The benchmark cosmetic preservative โ eu-permitted up to 1%, effective against virtually all cosmetically relevant microorganisms, and excellent tolerability.
How It Works: Phenol ring provides broad antimicrobial activity via disruption of bacterial and fungal cell membranes and inhibition of enzymatic activity. effective against gram-positive and gram-negative bacteria, yeasts (candida), and molds (aspergillus). activity ph range: 3-9.
Typically Found In: All cosmetic formulations as primary preservative

Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Phenoxyethanol's widespread adoption as the primary cosmetic preservative followed the phaseout of parabens from many formulations in the 2000s-2010s. despite having a comparable or better safety profile to parabens, it is often cited in 'free-from' formulations โ a consumer perception issue rather than a scientific safety concern.

Phospholipids
Common Name(s): Lecithin/phospholipid,cell membrane lipid,emulsifier barrier repair
CAS Number: N/a
DESCRIPTION
What It Does: Stabilises o/w and w/o emulsions through biomimetic phospholipid bilayer formation, supplements sc barrier lipids for barrier repair, and forms liposomes and lamellar delivery vehicles for encapsulated active delivery.
Why It's Used: Phospholipids are uniquely bifunctional: they provide conventional emulsification and form genuine liposomal bilayer vesicles for encapsulated active delivery โ a dual function unavailable from synthetic emulsifiers.
How It Works: The phosphocholine head group provides strong h-bonding hydrophilicity while the dual fatty acid tails provide lipophilic anchoring โ this wedge-shaped geometry spontaneously forms closed bilayer vesicles (liposomes) that encapsulate actives for sustained release and enhanced sc penetration.
Typically Found In: Emulsions,liposomal delivery,barrier repair
TECHNICAL DETAILS
Primary Category: Functional ingredient โ emollient
Secondary Functions: Barrier sealing,softening
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ15%
SOURCING & ETHICS
Vegan Status: Conditional
Halal Status: Yes
Source Notes: Plant-derived, synthetic or animal-derived. verify source.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 1/5 โ low; formulation-dependent
Sensitivity Concerns: Non-irritating.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Humectants,ceramides,actives as carrier
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Phospholipid's wedge-shaped geometry (large head relative to two acyl tails) preferentially forms spherical bilayer vesicles (liposomes) rather than flat lamellar phases โ this curvature preference enables self-assembly of drug delivery liposomes simply by hydration of the phospholipid film.
