Ingredients Details
Alanine
Common Name(s): L-alanine,2-aminopropanoic acid
CAS Number: 56-41-7
DESCRIPTION
What It Does: Provides nmf-type humectant moisture retention and skin conditioning.
Why It's Used: Simple, well-tolerated nmf amino acid humectant for skin conditioning formulations.
How It Works: Small methyl side chain contributes to protein hydrophobic core but as free amino acid provides direct humectant activity via amino and carboxyl groups. converted to pyruvate for cellular atp production via gluconeogenesis.
Typically Found In: Nmf moisturizers,skin conditioning products
TECHNICAL DETAILS
Primary Category: Active ingredient โ amino acid
Secondary Functions: Nmf component,cellular energy
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
Free alanine is among the most abundant amino acids in the stratum corneum nmf, where it contributes to the aqueous phase hydration that keeps the stratum corneum flexible and functional.

Amino Acids
Common Name(s): Amino acids,cosmetic active,functional ingredient
CAS Number: N/a
DESCRIPTION
What It Does: Delivers characteristic cosmetic function โ skin conditioning, protection, preservation, or active biological benefit โ at recommended use concentration.
Why It's Used: Selected for its functional contribution and formulation compatibility โ supported by cosmetic science literature and regulatory safety assessment.
How It Works: Works through the mechanism of its molecular class โ physicochemical interaction with the formulation or biological interaction with skin proteins, lipids, or receptors as documented in peer-reviewed literature.
Typically Found In: Skin care formulations
TECHNICAL DETAILS
Primary Category: Active ingredient โ cosmetic active
Secondary Functions: Skin conditioning
Application Areas:

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

Chitosan
Common Name(s): Chitosan,deacetylated chitin biopolymer,cationic film-former
CAS Number: N/a
DESCRIPTION
What It Does: Forms a substantive cationic film on skin and hair through electrostatic attraction to negative surfaces, provides antimicrobial activity against gram-positive bacteria and fungi, and promotes wound healing via keratinocyte and fibroblast stimulation.
Why It's Used: The only natural cationic biopolymer from shellfish providing simultaneous substantive deposition and antimicrobial activity โ preferred over synthetic quats for clean-label hair and skin conditioning.
How It Works: Protonated amine groups (pka ~6.5) in chitosan electrostatically bind hair cuticle and skin corneocytes (net negative charge at ph >5.5), depositing a film that reduces friction and provides conditioning. cationic character disrupts bacterial membranes providing antimicrobial activity.
Typically Found In: Hair conditioning,wound care,film-forming
