Copper Gluconate
Common Name(s): Cupric gluconate,copper(ii) d-gluconate
CAS Number: 0527-09-03
DESCRIPTION
What It Does: Provides bioavailable copper for skin enzyme cofactor functions including antioxidant, collagen crosslinking, and wound healing.
Why It's Used: Bioavailable organic copper for enzyme cofactor delivery to support antioxidant defense (sod), collagen maturation (lysyl oxidase), and wound healing.
How It Works: Cuยฒโบ is the cofactor for sod1 (antioxidant), tyrosinase (melanin), lysyl oxidase (collagen crosslinking), and cytochrome c oxidase (cellular energy). organic gluconate complexation improves bioavailability vs inorganic copper salts.
Typically Found In: Anti-aging serums,wound healing products,antioxidant formulations
TECHNICAL DETAILS
Primary Category: Active ingredient โ copper salt skin active
Secondary Functions: Sod cofactor,collagen crosslinking support,wound healing
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.01%โ0.5%
SOURCING & ETHICS
Vegan Status: Yes โ mineral/inorganic
Halal Status: Yes
Source Notes: Mineral/inorganic compound. cosmetic or pharmaceutical grade.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating at recommended concentrations.
Safe for Sensitive Skin: Yes at recommended concentrations
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile at cosmetic concentrations. ewg score: 1โ2.
Works Well With: Niacinamide,salicylic acid,other actives
Avoid Combining With: No significant incompatibilities at standard concentrations
SCIENTIFIC NOTE
Copper deficiency in skin manifests as impaired collagen crosslinking (reduced mechanical strength), reduced sod1 activity (increased oxidative stress), and hypopigmentation. topical copper supplementation addresses all three manifestations simultaneously through enzyme cofactor restoration.

Glyceryl Stearate Citrate
Common Name(s): Nonionic emulsifier,o/w surfactant,emulsion stabiliser
CAS Number: N/a
DESCRIPTION
What It Does: Stabilises o/w emulsions by forming a molecular monolayer at the oil-water interface, provides co-emulsification synergy with other emulsifiers, and contributes to emulsion texture through interfacial film properties.
Why It's Used: Nonionic emulsifiers are preferred for sensitive skin and ph-extreme formulations โ no ionic charge means no electrostatic interaction with skin proteins, no ph-dependent function loss, and compatibility with both anionic and cationic co-ingredients.
How It Works: Hlb determines emulsion type: hlb 8โ12 for o/w emulsification; hlb 3โ6 for w/o. the peg or glycoside head group provides hydrophilicity while the c16โc18 fatty chain provides lipophilicity. at the o/w interface, nonionic emulsifiers form a mixed monolayer reducing interfacial tension from ~35 mn/m (clean oil-water) to 5โ10 mn/m, providing thermodynamic stabilisation.
Typically Found In: Creams,lotions,o/w emulsions
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: 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
Mixed emulsifier systems (e.g., glyceryl stearate + peg-100 stearate, or cetearyl glucoside + cetearyl alcohol) provide better emulsion stability than single emulsifiers โ synergistic packing of different molecular geometries creates a more cohesive, mechanically robust interfacial film.

Madecassoside
Common Name(s): 6-o-beta-d-glucopyranosyl madecassic acid glycoside,centella triterpenoid glycoside
CAS Number: 34540-22-2
DESCRIPTION
What It Does: Stimulates collagen synthesis and wound healing while reducing inflammation โ the primary active in centella asiatica's skin repair activity.
Why It's Used: Standardized centella active for precise wound healing, collagen stimulation, and anti-inflammatory dosing with superior consistency vs whole centella extract.
How It Works: Activates tgf-beta1 receptor signaling to upregulate collagen i, iii, and iv synthesis in fibroblasts. inhibits nf-kb for anti-inflammatory activity. promotes keratinocyte migration and proliferation for re-epithelialization. also strengthens lamellar body structures.
Typically Found In: Post-procedure recovery,wound healing serums,anti-aging products,sensitive skin formulas

Secondary Functions: Collagen stimulation,wound healing,anti-inflammatory
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.01%โ2%
SOURCING & ETHICS
Vegan Status: Yes โ from centella asiatica
Halal Status: Yes
Source Notes: Extracted from centella asiatica aerial parts. standardized to madecassoside content for consistent bioactivity.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
