Ingredients Details
Bis-aminopropyl Diglycol Dimaleate
Common Name(s): Bis-aminopropyl diglycol dimaleate
DESCRIPTION
What It Does: Delivers targeted skin-conditioning or bioactive benefits through a specific mechanism of action suited to the formulation's intended purpose.
Why It's Used: Specialty actives address specific skin concerns through targeted molecular mechanisms, providing efficacy beyond what base formulation ingredients alone can achieve.
How It Works: The bioactive compound interacts with specific molecular targets in skin cells or the extracellular matrix โ enzymes, receptors, structural proteins, or signaling molecules โ triggering beneficial biological responses.
Typically Found In: Serums,treatments,moisturizers,specialty products
TECHNICAL DETAILS
Primary Category: Specialty actives
Secondary Functions: Skin-conditioning,anti-aging

SAFETY & COMPATIBILITY
Safety Profile: Well-characterized cosmetic ingredient with established safety profile. generally non-irritating at typical use concentrations. suitable for leave-on and rinse-off cosmetics.
Works Well With: Niacinamide,hyaluronic acid,vitamin c,peptides
Avoid Combining With: Incompatible with oxidizing agents; check ph stability
SCIENTIFIC NOTE
Specialty actives typically work through enzyme inhibition (e.g., tyrosinase inhibition for brightening, mmp inhibition for anti-aging), receptor activation (e.g., retinoid receptors, ppar-ฮณ for barrier genes), or transcription factor modulation (e.g., nrf2 for antioxidant gene upregulation). structure-activity relationships determine potency and selectivity.

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: Eu cosmetics regulation max 1%. sccs assessed as safe at โค1%. avoid use around eyes in baby products per some country regulations. ewg score: 4.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Phenoxyethanol's widespread adoption as the primary cosmetic preservative followed the phaseout of parabens from many formulations in the 2000s-2010s. despite having a comparable or better safety profile to parabens, it is often cited in 'free-from' formulations โ a consumer perception issue rather than a scientific safety concern.
