Ingredients Details
Bisabolol
Common Name(s): Alpha-bisabolol,levomenol,(-)-alpha-bisabolol
CAS Number: 515-69-5
DESCRIPTION
What It Does: Reduces skin inflammation, soothes irritation, promotes wound healing, and enhances penetration of co-formulated actives.
Why It's Used: Premium natural soothing active with combined anti-inflammatory, wound healing, and penetration-enhancing activity – clinically validated across sensitive, reactive, and irritated skin types.
How It Works: Inhibits nf-kb pathway reducing pro-inflammatory cytokines il-1β, il-6, tnf-α. enhances stratum corneum lipid fluidity increasing penetration of co-delivered actives. antimicrobial against s. aureus and c. albicans. promotes keratinocyte migration for wound healing.
Typically Found In: Sensitive skin products,post-procedure formulations,anti-irritant formulas,wound healing
TECHNICAL DETAILS
Primary Category: Active ingredient – soothing / anti-inflammatory
Secondary Functions: Anti-inflammatory,penetration enhancement,antimicrobial
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%–1%
SOURCING & ETHICS
Vegan Status: Yes – from candeia tree (vanillosmopsis erythropappa) or synthetic
Halal Status: Yes
Source Notes: Natural (-)-alpha-bisabolol from brazilian candeia tree is more sustainable and potent than chamomile-derived bisabolol. synthetic (±)-bisabolol is racemic with slightly lower anti-inflammatory potency.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – non-comedogenic
Sensitivity Concerns: Non-irritating; ideal for reactive and sensitive skin.
Safe for Sensitive Skin: Yes – particularly recommended for sensitive skin
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Ceramides,panthenol,allantoin,hyaluronic acid,centella asiatica
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Bisabolol's dual function as both an anti-inflammatory and a penetration enhancer is synergistic – by reducing the inflammatory response that increases barrier tightness while simultaneously fluidizing stratum corneum lipids, it provides enhanced delivery of co-formulated actives in the very conditions where delivery is most needed.

Isohexadecane
Common Name(s): Permethyl 101a,c16 isoparaffin
DESCRIPTION
What It Does: Provides ultra-lightweight dry-touch emolliency with excellent pigment dispersion for lightweight formulations.
Why It's Used: Premium lightweight emollient for dry-touch formulations — isohexadecane's highly branched structure provides the lightest, driest application feel of common cosmetic hydrocarbons.
How It Works: Highly branched c16 isoparaffin provides very low surface tension for fast spreading. completely non-polar structure provides no water retention (dry feel). excellent pigment wetting for colour cosmetics. very low viscosity (2.5 cst) for fluid application.
Typically Found In: Lightweight foundations,sunscreens,colour cosmetics,dry-touch products
TECHNICAL DETAILS
Primary Category: Functional ingredient – branched hydrocarbon 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%–30%
SOURCING & ETHICS
Vegan Status: Yes – synthetic hydrocarbon
Halal Status: Yes
Source Notes: Plant-derived, synthetic or animal-derived. verify source.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – non-comedogenic
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
Isohexadecane's highly branched structure (methyl-substituted hexadecane) prevents the close molecular packing that creates liquid crystalline phases in linear hydrocarbons, resulting in a permanently disordered liquid state with very low viscosity and surface tension. this structural disorder from branching is the molecular basis for the lighter, faster-spreading application feel vs equivalent linear hydrocarbons.
