Ethoxydiglycol
Common Name(s): Ethoxydiglycol,glycol co-solvent,humectant formulation aid
CAS Number: N/a
DESCRIPTION
What It Does: Provides co-solvent and penetration enhancer in cosmetic formulations, improving active ingredient dissolution and product texture while delivering mild skin conditioning.
Why It's Used: Glycol solvents are essential for dissolving actives with limited water or oil solubility โ the intermediate polarity of glycol ethers provides access to the wider solubility parameter space between pure water and oil phases.
How It Works: Hydroxyl and ether groups provide h-bonding for water miscibility; the organic chain provides compatibility with lipophilic actives. medium-chain glycols (c3โc6) provide the optimal balance of water compatibility, lipophilic active dissolution, and skin-compatible humectancy.
Typically Found In: Skin care formulations,co-solvent systems
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%โ30%
SOURCING & ETHICS
Vegan Status: Yes
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
Glycol ether co-solvents enhance sc penetration of co-applied actives by increasing their thermodynamic activity in the sc lipid phase โ high thermodynamic activity (near saturation) drives diffusion by concentration gradient even when absolute concentration is low.

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

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.
