Ingredients Details
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 โ 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 โ 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%โ5%
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
Comedogenicity Rating: 0/5 โ 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: 1โ2.
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 50-200ร 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.

Ceteth-20
Common Name(s): Ceteth-20,cosmetic active,established formulation ingredient
CAS Number: N/a
DESCRIPTION
What It Does: Ceteth-20 contributes its primary cosmetic function to formulations โ improving skin feel, stability, performance, or delivering a specific active benefit depending on its chemical class and concentration level.
Why It's Used: Formulators choose ceteth-20 for its established efficacy in contributing the required functional property to their formulation โ whether rheological control, active delivery, aesthetic enhancement, or preservation โ supported by the cosmetic chemistry literature and regulatory assessment framework.
How It Works: Ceteth-20 works through the characteristic mechanism of its chemical class โ either through physicochemical interaction with the formulation matrix (surface activity, film formation, viscosity building) or through biological interaction with skin tissues (receptor binding, enzymatic substrate, barrier component integration). the specific mechanism follows from its molecular structure as detailed in peer-reviewed cosmetic chemistry literature.
Typically Found In: Skin care formulations
TECHNICAL DETAILS
Primary Category: Active ingredient โ 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%โ10%
SOURCING & ETHICS
Vegan Status: Conditional
Halal Status: Yes

Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Good safety profile at recommended concentrations. ewg score: 1โ2.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Ceteth-20 has been assessed within the regulatory framework applicable to cosmetic ingredients. at standard cosmetic use concentrations, the ingredient delivers documented functional benefit with an established safety profile based on the available toxicological and clinical evidence reviewed by regulatory bodies including cosing (eu), inci, and cir.

Cholesterol
Common Name(s): 5-cholesten-3-ol,cholesterin
CAS Number: 57-88-5
DESCRIPTION
What It Does: Provides essential barrier sterol function as one of three critical stratum corneum lipid components.
Why It's Used: Essential component of complete barrier repair formulations โ the stratum corneum barrier requires ceramides:cholesterol:fatty acids in approximately 1:1:1 molar ratio for complete barrier restoration.
How It Works: Integrates between ceramide headgroups in lamellar body structures, providing fluidity and flexibility to the otherwise rigid ceramide-dominated lipid matrix. controls lamellar body phase behavior for functional barrier.
Typically Found In: Barrier repair moisturizers,eczema treatments,dry skin formulations
TECHNICAL DETAILS
Primary Category: Active ingredient โ barrier sterol
Secondary Functions: Lamellar body structure,barrier sterol
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.01%โ1%
SOURCING & ETHICS
Vegan Status: Conditional โ animal-derived (lanolin) or plant-derived phytosterol analogs; verify
Halal Status: Conditional โ verify source
Source Notes: Traditionally from lanolin (wool grease). plant-derived cholesterol alternatives include phytosterols, though these show slightly different barrier integration. verify for vegan/halal.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Endogenous molecule; excellent tolerability.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Exceptional safety profile. natural skin component. ewg score: 1.
Works Well With: Other ceramides,cholesterol,free fatty acids,hyaluronic acid,niacinamide
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Elias demonstrated that barrier repair requires all three lipid classes (ceramides, cholesterol, fatty acids) in approximately equimolar ratios. formulations providing only ceramides without cholesterol and fatty acids show significantly inferior barrier restoration vs complete triple-lipid combinations.

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 โ 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 โ nearly universal
TECHNICAL DETAILS
Primary Category: Functional ingredient โ 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%โ30%
SOURCING & ETHICS
Vegan Status: Yes โ synthetic
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
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 โ explaining why even small amounts transform product feel.
