Ingredients Details
Arginine
Common Name(s): L-arginine,2-amino-5-guanidinopentanoic acid
CAS Number: 74-79-3
DESCRIPTION
What It Does: Conditions skin, attracts moisture, supports wound healing, and improves microcirculation via no synthesis.
Why It's Used: Multi-functional amino acid for skin hydration, conditioning, and wound healing in peptide and nmf formulations.
How It Works: Guanidinium group binds water (humectant). substrate for nitric oxide synthase (enos) producing nitric oxide that vasodilates capillaries improving skin nutrition. stimulates fibroblast proliferation for wound healing.
Typically Found In: Anti-aging serums,wound healing products,nmf moisturizers,scalp treatments
TECHNICAL DETAILS
Primary Category: Active ingredient – amino acid
Secondary Functions: Wound healing,microcirculation,nmf component
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.5%–5%
SOURCING & ETHICS
Vegan Status: Yes – plant-derived or synthetic
Halal Status: Yes
Source Notes: Fermentation-derived or synthetic. natural skin component.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – non-comedogenic
Sensitivity Concerns: Non-irritating; endogenous skin molecule.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. natural skin nmf component. ewg score: 1.
Works Well With: Hyaluronic acid,ceramides,peptides,other amino acids
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Arginine is a conditionally essential amino acid in wound healing where local demand exceeds synthesis capacity. topical arginine provides the nos substrate locally for no-mediated vasodilation and immune cell function in healing tissue.

Camelina Sativa Seed Oil
Common Name(s): Camelina sativa seed oil,botanical oil/butter,phytochemical active
CAS Number: N/a
DESCRIPTION
What It Does: Provides emollient conditioning, essential fatty acid supplementation, and barrier lipid support from the natural triglyceride/wax ester composition.
Why It's Used: Natural carrier oils provide sc-compatible lipid composition for genuine barrier integration rather than surface-only occlusion.
How It Works: Fatty acid triglycerides integrate into sc lipid bilayers delivering oleic, linoleic, and linolenic acid for emolliency and barrier repair; essential fatty acids serve as ceramide biosynthesis precursors.
Typically Found In: Botanical skin care,natural products
TECHNICAL DETAILS
Primary Category: Active ingredient – antioxidant
Secondary Functions: Free radical scavenging,anti-aging
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%–30%
SOURCING & ETHICS
Vegan Status: Conditional
Halal Status: Conditional
Source Notes: Plant-derived extract or synthetic.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – non-comedogenic
Sensitivity Concerns: Non-irritating; well-tolerated.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Vitamin c,vitamin e,ferulic acid,spf,other antioxidants
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Plant secondary metabolites evolved for uv photoprotection and pathogen defence — mechanisms directly applicable to cosmetic antioxidant and anti-inflammatory activity in human skin.

Coumarin
Common Name(s): 2h-chromen-2-one,1,2-benzopyrone,tonka bean compound
CAS Number: 91-64-5
DESCRIPTION
What It Does: Provides the characteristic sweet hay-vanilla warmth central to fougère fragrance compositions.
Why It's Used: The fougère fragrance family-defining compound – coumarin is the essential warm-sweet note in lavender-oakmoss-coumarin fougère compositions that define men's cologne classics.
How It Works: Bicyclic lactone provides sweet hay-vanilla scent from its conjugated carbonyl system. good skin absorption for lasting fragrance. low volatility provides fixative properties.
Typically Found In: Fougère fragrances,men's cologne,warm oriental fragrances
TECHNICAL DETAILS
Primary Category: Fragrance component – lactone
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%–1%
SOURCING & ETHICS
Vegan Status: Yes – synthetic; natural from dipteryx odorata
Halal Status: Yes
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – 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. ifra guidelines restrict due to hepatotoxicity at high oral doses (not from topical use).
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Coumarin's natural source (tonka beans, dipteryx odorata) led to its historical use in food flavouring until toxicological studies revealed hepatotoxicity at high oral doses. the restriction of coumarin from food flavouring (eu and fda) drove fragrance reformulation in some cosmetic categories, though topical exposure levels from cosmetics are orders of magnitude below hepatotoxic doses.

Dimethicone
Common Name(s): Pdms,polydimethylsiloxane,silicone fluid
CAS Number: 9006-65-9
DESCRIPTION
What It Does: Provides silicone-characteristic silky feel and skin protection with adjustable viscosity.
Why It's Used: The benchmark cosmetic silicone – sets the gold standard for silky application feel, spreadability, and skin protection in virtually all skin care categories.
How It Works: Polydimethylsiloxane chain flexibility provides extremely low surface tension and high spreadability. inert si-o backbone provides chemical stability and excellent skin tolerance. occlusive film formation reduces tewl. higher viscosity grades provide more intense conditioning.
Typically Found In: Moisturizers,foundations,primers,sunscreens – nearly universal
TECHNICAL DETAILS
Primary Category: Functional ingredient – polydimethylsiloxane
Secondary Functions: Barrier sealing,softening
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%–30%
SOURCING & ETHICS
Vegan Status: Yes – synthetic
Halal Status: Yes
Source Notes: Plant-derived, synthetic or animal-derived. verify source.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 1/5 – 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
Dimethicone's exceptional silky feel arises from its very low intermolecular attractive forces (weak van der waals forces due to non-polar methyl groups) that allow silicone chains to slide freely over skin. the coefficient of kinetic friction for pdms against skin (~0.04) is among the lowest of any cosmetic material – explaining why even small amounts transform product feel.
