Why This Works for Your Specific Profile
Damage Index:
Very healthy or severely damaged hair falls outside optimal treatment parameters
Water Quality:
Fine hair becomes weighed down and greasy from heavy formulation
Hair:
Porous structure over-absorbs product leading to buildup, stiffness, or excessive dryness
Active Lifestyle:
High activity and frequent washing rapidly strip product benefits requiring excessive reapplication

Typically Found In: Hair growth shampoos,nail treatments,multivitamin products
TECHNICAL DETAILS
Primary Category: Active ingredient โ vitamin b7
Secondary Functions: Hair growth support,nail strengthening
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.01%โ0.5%
SOURCING & ETHICS

SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating; excellent tolerability.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Other b vitamins,niacinamide,antioxidant complexes
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Evidence for topical biotin efficacy in hair growth is limited โ most clinical evidence comes from oral supplementation in biotin-deficient individuals.

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)
Dietary/Oral Supplements
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.

Dimethicone
Common Name(s): Pdms,polydimethylsiloxane,silicone fluid
CAS Number: 9006-65-9
DESCRIPTION
What It Does: Provides silicone-characteristic silky feel and skin protection with adjustable viscosity.
Why It's Used: The benchmark cosmetic silicone โ sets the gold standard for silky application feel, spreadability, and skin protection in virtually all skin care categories.
How It Works: Polydimethylsiloxane chain flexibility provides extremely low surface tension and high spreadability. inert si-o backbone provides chemical stability and excellent skin tolerance. occlusive film formation reduces tewl. higher viscosity grades provide more intense conditioning.
Typically Found In: Moisturizers,foundations,primers,sunscreens โ nearly universal
TECHNICAL DETAILS
Primary Category: Functional ingredient โ polydimethylsiloxane
Secondary Functions: Barrier sealing,softening
Application Areas:
Facial Skincare

Typical Concentration Range: 0.1%โ30%

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
Dimethicone's exceptional silky feel arises from its very low intermolecular attractive forces (weak van der waals forces due to non-polar methyl groups) that allow silicone chains to slide freely over skin. the coefficient of kinetic friction for pdms against skin (~0.04) is among the lowest of any cosmetic material โ explaining why even small amounts transform product feel.
