Ingredients Details
Argania Spinosa Kernel Oil
Common Name(s): Argania spinosa kernel 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.

Cyclopentasiloxane
Common Name(s): Cyclopentasiloxane,cyclic volatile silicone,dry-touch carrier solvent
CAS Number: N/a
DESCRIPTION
What It Does: Provides a dry, weightless application vehicle that evaporates cleanly leaving actives and non-volatile silicones deposited on skin โ eliminating the residual heaviness of conventional liquid carrier solvents.
Why It's Used: Cyclosiloxanes are the unique volatile silicone solvents that dissolve non-volatile silicones (dimethicone, cyclomethicone), organic uv filters, and lipophilic actives, providing the sensory-superior dry-touch application experience in premium formulations.
How It Works: Cyclosiloxane vapour pressure (d5 cyclopentasiloxane ~0.3 mmhg at 25ยฐc) provides clean evaporation at body temperature. the cyclic ring structure provides lower boiling point than equivalent linear dimethicone, enabling faster evaporation while the ring conformation maintains the silicone's low surface energy for smooth application.
Typically Found In: Primers,antiperspirants,sunscreens
