Ingredients Details
Citronellol
Common Name(s): (r)-3,7-dimethyl-6-octen-1-ol,rhodinol
CAS Number: 106-22-9
DESCRIPTION
What It Does: Provides soft, lasting rose-floral fragrance note.
Why It's Used: Essential rose fragrance monoterpene for lasting smooth floral notes in high-quality perfumery and cosmetic fragrances.
How It Works: Allylic alcohol monoterpene provides fixative property in fragrance blends. good skin substantivity for lasting scent. softer, rounder rose note vs geraniol's fresher character. natural in rose otto at 18-34%.
Typically Found In: Rose perfumes,floral fragrances,luxury skincare
TECHNICAL DETAILS
Primary Category: Fragrance component โ monoterpene alcohol
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.001%โ1%
SOURCING & ETHICS
Vegan Status: Yes โ from rose, geranium, citronella oils
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: Eu cosmetics regulation: declared fragrance allergen. ifra guidelines apply.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Citronellol's r-enantiomer (natural) vs s-enantiomer (synthetic) provide meaningfully different scent character โ a remarkable demonstration of chiral scent discrimination by olfactory receptors. the (r) form provides the characteristic rose note while the (s) form has a distinctly different, less pleasant character. this enantiomeric scent difference means that the biological handedness of naturally-sourced vs racemic synthetic citronellol produces perceptibly different fragrance quality.

Cyclohexasiloxane
Common Name(s): D6,cyclomethicone d6,hexamethylcyclotrisiloxane
CAS Number: 540-97-6
DESCRIPTION
What It Does: Provides volatile silicone delivery with longer contact time than d5 for extended active delivery.
Why It's Used: Longer-evaporation volatile silicone for formulations requiring extended delivery contact time vs d5's rapid evaporation.
How It Works: Larger ring (6 silicone units) provides lower vapor pressure than d5 (5 units). slower evaporation rate (2-3ร longer than d5) provides extended delivery window. same dry-touch after complete evaporation.
Typically Found In: Longer-duration volatile vehicles,serum formulations
TECHNICAL DETAILS
Primary Category: Functional ingredient โ volatile cyclic silicone
Secondary Functions: Skin conditioning
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 โ synthetic
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: Eu restrictions on d5 do not apply to d6 โ d6 may be used in rinse-off products without restriction.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
The different evaporation rates of d4 (methylcyclosiloxane), d5, and d6 provide formulators with a toolkit of volatile silicone delivery windows: d4 evaporates in ~1 minute, d5 in ~5 minutes, d6 in ~15 minutes. blending these provides precisely tunable evaporation kinetics for specific delivery timing requirements.

Cyclopentasiloxane
Common Name(s): Cyclopentasiloxane,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
TECHNICAL DETAILS
Primary Category: Functional ingredient โ emollient
Secondary Functions: Barrier sealing,softening
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)

Typical Concentration Range: 1%โ50%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Plant-derived, synthetic or animal-derived. verify source.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 1/5 โ low; formulation-dependent
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
Cyclopentasiloxane (d5) and cyclohexasiloxane (d6) are under eu regulatory review for potential environmental persistence (pbt assessment) โ formulators should monitor eu regulation 2018/35 implementation for restrictions in wash-off products.
