Ingredients Details
Acetic Acid
Common Name(s): Acetic acid,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 as documented in peer-reviewed cosmetic 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
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
Acetic acid has an established safety profile within the cosmetic regulatory framework at standard use concentrations.
Last Verified: Cosing database,acetic acid technical literature

Almond Oil
Common Name(s): Almond oil,botanical carrier oil,emollient fatty acid delivery
CAS Number: N/a
DESCRIPTION
What It Does: Softens and conditions skin by integrating into sc lipid bilayers, delivers essential fatty acids (oleic, linoleic, linolenic) for barrier lipid synthesis, and provides rich, non-stripping moisturisation.
Why It's Used: Natural carrier oils provide the closest compositional match to endogenous sc lipids, delivering emolliency through genuine barrier integration rather than simple surface occlusion.
How It Works: Fatty acid triglycerides partition into sc lipid bilayers โ oleic acid (c18:1) provides fluid, emollient integration; linoleic acid (c18:2) acts as essential ceramide precursor; saturated fatty acids provide more occlusive barrier reinforcement.
Typically Found In: Moisturisers,facial oils,natural skin care
TECHNICAL DETAILS
Primary Category: Functional ingredient โ emollient
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%โ100%
SOURCING & ETHICS
Vegan Status: Conditional
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
Essential fatty acids โ linoleic (c18:2, n-6) and ฮฑ-linolenic (c18:3, n-3) acids โ cannot be synthesised by the body; topical delivery through carrier oils provides direct substrate for ceramide and eicosanoid biosynthesis in the epidermis.

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.

Ascorbyl Palmitate
Common Name(s): L-ascorbyl-6-palmitate,vitamin c palmitate,fat-soluble vitamin c
CAS Number: 137-66-6
DESCRIPTION
What It Does: Provides lipid-soluble antioxidant protection in skin and oil-based formulations.
Why It's Used: Oil-based formulations as fat-soluble vitamin c active and formulation antioxidant preservative (e304).
How It Works: Skin esterases cleave the bond releasing ascorbic acid and palmitic acid. lipophilic form may integrate into cell membranes for lipid-phase antioxidant protection.
Typically Found In: Oil serums,emulsions,sunscreens,anti-aging creams
TECHNICAL DETAILS
Primary Category: Active ingredient โ vitamin c derivative
Secondary Functions: Lipid-soluble antioxidant,formulation preservative
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%โ1%
SOURCING & ETHICS
Vegan Status: Yes โ synthetic
Halal Status: Yes
Source Notes: Esterification of ascorbic acid with palmitic acid. gras food additive (e304).
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 1/5 โ very low; palmitic acid minor concern
Sensitivity Concerns: Non-irritating; suitable for all skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Tocopherol,ferulic acid,niacinamide,spf
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Debate exists about efficiency of ester hydrolysis in intact skin and prooxidant potential of uv degradation products. formulating with the antioxidant triad (c+e+ferulic) mitigates this concern.
