Ingredients Details
Acrylates/c10-30 Alkyl Acrylate Crosspolymer
Common Name(s): Acrylates/c10-30 alkyl acrylate crosspolymer
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
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.01โ5%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Specialty active ingredient; check individual sourcing for vegan status.
SKIN COMPATIBILITY
Irritancy Rating: 1
Comedogenicity Rating: 0
Sensitivity Concerns: Low sensitization potential at recommended use concentrations.
Safe for Sensitive Skin: Yes
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.

Biosaccharide Gum-2
Common Name(s): Biosaccharide gum-2,biosaccharide gum-2,microbial exopolysaccharide,biotechnology polysaccharide active
CAS Number: N/a
DESCRIPTION
What It Does: Provides moisture retention from the polysaccharide's multiple hydroxyl groups, film-forming conditioning from the polymer chain architecture, and in some grades prebiotic selective fermentation by beneficial skin microbiome organisms.
Why It's Used: Microbial biosaccharides provide pharmaceutical-grade consistency unavailable from plant polysaccharides โ controlled fermentation delivers the same polysaccharide structure and mw distribution every batch for reproducible clinical performance.
How It Works: Microbial eps fermentation in defined bioreactor medium โ specific polysaccharide backbone structure determined by organism's transferase enzymes โ consistent mw distribution (mw/mn < 1.5) โ reproducible rheological and biological properties. the specific polysaccharide structure determines: moisture retention (h-bonding density), film quality (chain flexibility), and prebiotic selectivity (monosaccharide composition).
Typically Found In: Skin care,microbiome formulas
TECHNICAL DETAILS
Primary Category: Active ingredient โ skin microbiome support
Secondary Functions: Microbiome balance,prebiotic effect
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%โ5%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Fermentation-derived or plant-extracted.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating; beneficial for sensitive skin.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Ceramides,niacinamide,soothing actives
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Biosaccharide gum grades are organism-specific โ each biosaccharide gum number designates a specific organism and structure with distinct functional properties. formulators should characterise the specific grade's viscosity, water retention, and prebiotic activity for target application.

Caprylic/capric Triglyceride
Common Name(s): Mct oil,fractionated coconut oil,c8/c10 triglyceride
CAS Number: 73398-61-5
DESCRIPTION
What It Does: Lightweight, stable emollient that solubilizes oil-soluble actives for excellent delivery without greasy feel.
Why It's Used: Universal lightweight emollient base and solubilizer for oil-soluble actives in serums and low-viscosity formulations where mineral oil or petrolatum would be too heavy.
How It Works: Medium-chain length provides ideal balance of spreading coefficient, penetration rate, and barrier-sealing properties. excellent solubilizer for vitamin e, retinoids, and other lipophilic actives.
Typically Found In: Serums,facial oils,sunscreens,anti-aging products,hair products
TECHNICAL DETAILS
Primary Category: Active ingredient โ medium-chain triglyceride emollient
Secondary Functions: Active solubilizer,spreading agent
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ50%
SOURCING & ETHICS
Vegan Status: Yes โ from coconut/palm kernel oil
Halal Status: Yes
Source Notes: Fractionated by hydrolysis and re-esterification of coconut oil. only c8 and c10 fatty acids retained.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 1/5 โ very low; medium-chain length generally 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
Mct oil's medium-chain length (c8/c10) provides superior oxidative stability vs longer polyunsaturated chains and better skin aesthetics (lighter, less greasy) vs longer chain emollients (c16/c18). excellent solubilizer for retinoic acid, tocopheryl esters, and other lipophilic actives.
