DESCRIPTION

What It Does: Provides rich classic jasmine-type floral fragrance note.

Why It's Used: Classic jasmine fragrance aldehyde for premium perfumery providing the richer, deeper jasmine note used in high-quality fragrance compositions.

SCIENTIFIC NOTE

Amyl cinnamal and hexyl cinnamal differ only in the alpha-substituent chain length (c5 amyl vs c6 hexyl). this single carbon difference shifts the scent character from amyl cinnamal's broader, richer jasmine to hexyl cinnamal's crisper, airier jasmine – demonstrating the extraordinary sensitivity of olfactory receptors to minor molecular changes in linear chain length.

DESCRIPTION

What It Does: Softens and conditions skin by integrating into sc lipid bilayers, delivers essential fatty acids (oleic, linoleic, linolenic) for barrier lipid synthesis, and provides rich, non-stripping moisturisation.

Why It's Used: Natural carrier oils provide the closest compositional match to endogenous sc lipids, delivering emolliency through genuine barrier integration rather than simple surface occlusion.

How It Works: Fatty acid triglycerides partition into sc lipid bilayers — oleic acid (c18:1) provides fluid, emollient integration; linoleic acid (c18:2) acts as essential ceramide precursor; saturated fatty acids provide more occlusive barrier reinforcement.

Typically Found In: Moisturisers,facial oils,natural skin care

DESCRIPTION

What It Does: Provides the defining intense lemon-citrus fragrance note.

Why It's Used: The lemon scent compound – citral defines the fresh lemon scent in lemon essential oil and lemongrass with potent antimicrobial activity.

How It Works: Mixture of e-isomer (geranial) and z-isomer (neral). antimicrobial via michael addition to thiol enzymes. inhibits nf-kb for anti-inflammatory activity. antioxidant via allylic aldehyde.

Typically Found In: Citrus fragrances,antibacterial products,lemon-scented cosmetics

SAFETY & COMPATIBILITY

Safety Profile: Eu cosmetics regulation: declared fragrance allergen. high sensitisation potential from alpha,beta-unsaturated aldehyde structure. ifra strict limits.

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Citral's high sensitisation potential (llna ec3 ~0.11%) is a consequence of its alpha,beta-unsaturated aldehyde structure providing a highly reactive michael acceptor for skin protein covalent binding. the e/z mixture (geranial/neral) in natural citral means both isomers contribute to the sensitisation burden – explaining why lemongrass oil (very high citral content, ~60-80%) is one of the more common essential oil allergens.

SCIENTIFIC NOTE

Citronellol's r-enantiomer (natural) vs s-enantiomer (synthetic) provide meaningfully different scent character – 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.

DESCRIPTION

What It Does: Provides a dry, weightless application vehicle that evaporates cleanly leaving actives and non-volatile silicones deposited on skin — 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 25°c) 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.

DESCRIPTION

What It Does: Provides silicone-characteristic silky feel and skin protection with adjustable viscosity.

Why It's Used: The benchmark cosmetic silicone – 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.

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 – explaining why even small amounts transform product feel.

DESCRIPTION

What It Does: Provides warm clove fragrance note with local anaesthetic and antimicrobial properties.

Why It's Used: Natural local anaesthetic fragrance – eugenol provides clove's dual function as both a fragrance compound and a topical anaesthetic used in dentistry for pain relief.

How It Works: Activates trpv1 for local anaesthetic desensitisation (same mechanism as capsaicin but much weaker). inhibits cox and lox for anti-inflammatory activity. membrane disruption for antimicrobial activity. antioxidant via phenolic radical scavenging.

SCIENTIFIC NOTE

Eugenol's dental anaesthetic use predates modern pharmaceutical dentistry – oil of cloves (primarily eugenol) has been used for toothache relief for centuries. modern dentistry still uses eugenol in zinc oxide-eugenol cement for temporary cavity filling, where eugenol's trpv1 desensitisation provides pain relief while zinc oxide provides structural material – a pharmaceutical application of a fragrance compound still standard in clinical dentistry.
