Cyclomethicone
Common Name(s): Cyclomethicone,cyclic volatile silicone,dry-touch carrier solvent
CAS Number: N/a
DESCRIPTION
What It Does: Provides a dry, weightless application vehicle that evaporates cleanly leaving actives and non-volatile silicones deposited on skin โ eliminating the residual heaviness of conventional liquid carrier solvents.
Why It's Used: Cyclosiloxanes are the unique volatile silicone solvents that dissolve non-volatile silicones (dimethicone, cyclomethicone), organic uv filters, and lipophilic actives, providing the sensory-superior dry-touch application experience in premium formulations.
How It Works: Cyclosiloxane vapour pressure (d5 cyclopentasiloxane ~0.3 mmhg at 25ยฐc) provides clean evaporation at body temperature. the cyclic ring structure provides lower boiling point than equivalent linear dimethicone, enabling faster evaporation while the ring conformation maintains the silicone's low surface energy for smooth application.
Typically Found In: Primers,antiperspirants,sunscreens

Primary Category: Functional ingredient โ emollient
Secondary Functions: Barrier sealing,softening
Application Areas:
Facial Skincare
Body Care
Hair Care

Dietary/Oral Supplements
Typical Concentration Range: 1%โ50%
SOURCING & ETHICS
Vegan Status: Yes

Dipropylene Glycol
Common Name(s): Dipropylene glycol,glycol co-solvent,humectant formulation aid
CAS Number: N/a
DESCRIPTION
What It Does: Provides humectant, co-solvent, and fragrance fixative 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.
