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 โ 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%โ5%
SOURCING & ETHICS
Vegan Status: Yes โ plant-derived or synthetic
Halal Status: Yes
Source Notes: Fermentation-derived or synthetic. natural skin component.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ 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.

Cetearyl Alcohol
Common Name(s): Cetostearyl alcohol,c16-18 fatty alcohol
CAS Number: 8005-44-5
DESCRIPTION
What It Does: Provides fatty alcohol emulsification and thickening for stable, well-textured emulsions.
Why It's Used: The most widely used fatty alcohol in cosmetics โ provides emulsification, thickening, and emolliency simultaneously from a single ingredient with excellent safety profile.
How It Works: Forms bilayer lamellar structures in water with emulsifiers creating a viscous structured network that thickens and stabilizes emulsions. fatty alcohol emolliency provides direct skin conditioning. bilayer formation reduces inter-droplet coalescence in emulsions.
Typically Found In: Creams,lotions,conditioners โ virtually all emulsion products
TECHNICAL DETAILS
Primary Category: Functional ingredient โ fatty alcohol emulsifier/thickener
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%โ25%
SOURCING & ETHICS
Vegan Status: Yes โ from vegetable or coconut/palm fatty acids
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
Cetearyl alcohol's ability to form lamellar liquid crystal structures ('krafft phases') with water and co-emulsifiers provides not only emulsion stability but also enhanced skin penetration via the lamellar skin barrier pathway. these crystalline structures can act as a reservoir for active ingredients, slowly releasing them as the lamellar structure melts on skin contact.

Cetyl Alcohol
Common Name(s): 1-hexadecanol,palmityl alcohol,n-cetyl alcohol
CAS Number: 36653-82-4
DESCRIPTION
What It Does: Provides c16 fatty alcohol emolliency and thickening for well-textured cosmetic emulsions.
Why It's Used: Lighter-textured fatty alcohol alternative to stearyl alcohol for creams and conditioners requiring less heavy emolliency.
How It Works: C16 chain length provides slightly lower melting point (49ยฐc) than stearyl (60ยฐc) giving softer, lighter emulsion texture. forms lamellar networks for thickening and stability. direct skin and hair conditioning via fatty alcohol film.
Typically Found In: Creams,hair conditioners,lotions
TECHNICAL DETAILS
Primary Category: Functional ingredient โ fatty alcohol
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: Yes โ from vegetable or coconut/palm fatty acids
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
Cetyl alcohol's c16 chain length is at the approximate thermal transition point for fatty alcohol lamellar crystallization at skin temperature (33ยฐc). this transition (from ordered crystalline to disordered liquid phase near skin temperature) provides the characteristic 'melts on application' sensory profile that makes cetyl alcohol-containing products feel cooling and light on initial application.

Cetyl Phosphate
Common Name(s): Cetyl phosphate
DESCRIPTION
What It Does: Smooths and softens skin by filling intercorneocyte spaces, reducing friction, and providing a pleasant aesthetic skin feel in formulations.
Why It's Used: Synthetic esters provide tailored aesthetic properties โ spreadability, skin feel, volatility, refractive index โ that natural oils alone cannot consistently deliver.
How It Works: The ester molecule fills microscopic surface irregularities between corneocytes, reducing coefficient of friction, reflecting light uniformly, and providing a lubrication layer that protects the skin surface.
Typically Found In: Moisturizers,sunscreens,color cosmetics,body lotions,lip products
TECHNICAL DETAILS
Primary Category: Synthetic emollients
Secondary Functions: Emollient
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1โ20%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Synthetically produced ester emollient; no animal components.
SKIN COMPATIBILITY
Irritancy Rating: 1
Comedogenicity Rating: 1
Sensitivity Concerns: Low sensitization potential at recommended use concentrations.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Well-characterized cosmetic ingredient with established safety profile. generally non-irritating at typical use concentrations. suitable for leave-on and rinse-off cosmetics.
Works Well With: Silicones,uv filters,other emollients
Avoid Combining With: Strongly alkaline conditions (risk of saponification of ester-type emollients)
SCIENTIFIC NOTE
The spreading coefficient of an emollient is governed by its surface tension, viscosity, and polarity. esters with branched alkyl chains (e.g., isopropyl, isostearyl) spread rapidly and leave a non-tacky film; linear long-chain esters provide more substantive moisturization. hlb value determines the preferred formulation system (w/o vs o/w emulsions).
