Ingredients Details
Coconut Oil
Common Name(s): Coconut oil,botanical oil,phytochemical active
CAS Number: N/a
DESCRIPTION
What It Does: Provides antioxidant protection from reactive oxygen species, reduces inflammatory cytokine production in skin, and conditions skin through the plant's phytochemical complex.
Why It's Used: Natural origin narrative, traditional use heritage, and multi-functional phytochemical profile supporting concurrent skin care claims from one ingredient.
How It Works: Polyphenols, terpenoids, and alkaloids scavenge ros via hโข donation, inhibit nf-kb or cox-2 inflammatory pathways, and interact with skin surface proteins for conditioning.
Typically Found In: Botanical skin care,natural products
TECHNICAL DETAILS
Primary Category: Active ingredient โ antioxidant
Secondary Functions: Free radical scavenging,anti-aging
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: Plant-derived extract or synthetic.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating; well-tolerated.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Vitamin c,vitamin e,ferulic acid,spf,other antioxidants
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Plant secondary metabolites evolved as photoprotectants and antimicrobials โ mechanisms directly applicable to cosmetic antioxidant and anti-inflammatory activity in human skin.

Propanediol
Common Name(s): 1,3-propanediol,zemea,bio-propanediol
CAS Number: 504-63-2
DESCRIPTION
What It Does: Provides humectant and solvent functionality from sustainable corn-based fermentation.
Why It's Used: Bio-based propylene glycol alternative from renewable corn โ propanediol provides equivalent functionality to propylene glycol with sustainable renewable feedstock and superior skin feel.
How It Works: Two oh groups provide humectant water binding. excellent solvent for fragrances, actives, and preservatives. mild antimicrobial from diol structure for preservative system boosting. renew corn fermentation origin (dupont zemea process). better skin feel than propylene glycol โ less sticky.
Typically Found In: Virtually all cosmetic categories as pg alternative
TECHNICAL DETAILS
Primary Category: Functional ingredient โ humectant
Secondary Functions: Tewl reduction,skin plumping
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ20%
SOURCING & ETHICS
Vegan Status: Yes โ from corn sugar fermentation
Halal Status: Yes
Source Notes: Synthetic or naturally derived. excellent aqueous solubility.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
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: Ceramides,emollients,occlusives,glycerin,hyaluronic acid
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Propanediol's dupont tate & lyle bio products 'zemea' process ferments corn sugar to 1,3-propanediol using engineered e. coli โ one of the first commercially viable bio-fermentation routes to a cosmetic diol previously made only from petroleum. the renewable route produces chemically identical 1,3-propanediol while reducing carbon footprint by approximately 40% vs petrochemical synthesis.

Squalane
Common Name(s): Perhydrosqualene,2,6,10,15,19,23-hexamethyltetracosane
CAS Number: 0111-01-03
DESCRIPTION
What It Does: Provides endogenous-skin-identical emolliency with exceptional stability and skin compatibility.
Why It's Used: The most skin-compatible emollient โ chemically identical to human sebum squalene component with outstanding tolerability across all skin types.
How It Works: Fully saturated hydrocarbon with zero oxidation sites provides exceptional stability unlike squalene's 6 double bonds. integrates into stratum corneum lipid bilayers with near-perfect biocompatibility. provides antioxidant protection to formulation via radical quenching.
Typically Found In: Facial oils,serums,non-comedogenic moisturizers,luxury body care
TECHNICAL DETAILS
Primary Category: Functional ingredient โ emollient
Secondary Functions: Maximum biocompatibility,antioxidant stabilizer,non-comedogenic
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 โ plant-derived (sugarcane, olive) preferred; shark liver-derived being phased out
Halal Status: Yes โ plant-derived
Source Notes: Sustainable plant-derived squalane from sugarcane fermentation (amyris) or olive oil fractionation is preferred over shark liver-derived. chemically identical regardless of source.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ 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
Squalene constitutes approximately 12-15% of human sebum โ the highest proportion of any skin lipid. topical squalane (stable, hydrogenated form) replenishes this abundant endogenous skin lipid. the complete absence of oxidizable double bonds (unlike squalene's 6 double bonds) eliminates the pro-oxidant concerns of natural squalene oxidation.
