Ingredients Details
1-2-hexanediol
Common Name(s): 1-2-hexanediol,cosmetic active,functional ingredient
CAS Number: N/a
DESCRIPTION
What It Does: Delivers characteristic cosmetic function at recommended use concentration.
Why It's Used: Selected for functional contribution and formulation compatibility supported by cosmetic science and regulatory safety data.
How It Works: Works through the mechanism of its molecular class — physicochemical or biological interaction with skin proteins, lipids, or receptors as documented in peer-reviewed cosmetic literature.
Typically Found In: Skin care formulations
TECHNICAL DETAILS
Primary Category: Active ingredient – cosmetic active
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%–10%
SOURCING & ETHICS
Vegan Status: Conditional
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: Good safety profile at recommended concentrations. ewg score: 1–2.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
1-2-hexanediol has an established safety and efficacy profile within the cosmetic regulatory framework at standard use concentrations.

Amodimethicone
Common Name(s): Aminosilicone,amino-modified polydimethylsiloxane
CAS Number: 71750-79-3
DESCRIPTION
What It Does: Provides amino group-mediated preferential adsorption to damaged hair for targeted conditioning.
Why It's Used: Premium hair conditioning silicone – amino groups provide substantive adsorption to hair far exceeding pdms, with automatic targeting to the most damaged areas requiring conditioning.
How It Works: Amino (nh2) groups on silicone chain provide cationic character at normal ph, electrostatic adsorption to anionic hair surface. higher charge density at damaged sites increases adsorption where conditioning is most needed. si-o-si backbone provides permanent conditioning film with heat protection.
Typically Found In: Intensive conditioners,anti-frizz products,damage repair conditioners
TECHNICAL DETAILS
Primary Category: Functional ingredient – amino-functional silicone
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%–5%
SOURCING & ETHICS
Vegan Status: Yes – synthetic
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: Good safety profile at recommended concentrations. ewg score: 1–2.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Amodimethicone's amino group-driven substantivity to damaged hair is dramatically greater than non-functionalized pdms. studies show amodimethicone deposits 50-200× more mass on bleach-damaged hair vs virgin hair, providing an automatic 'damage detection' conditioning system that directs the most conditioning to the hair areas that need it most.

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.

Biotin
Common Name(s): Vitamin b7,vitamin h,d-biotin
CAS Number: 58-85-5
DESCRIPTION
What It Does: Supports keratin production for stronger hair and nails.
Why It's Used: Hair and nail keratin infrastructure support; widely marketed despite evidence being primarily oral supplementation-based.
How It Works: Coenzyme for carboxylase enzymes essential for fatty acid synthesis and amino acid metabolism relevant to hair follicle function.
Typically Found In: Hair growth shampoos,nail treatments,multivitamin products
