Other
Cyclodextrin

Ring-shaped oligosaccharides (α, β, or γ forms) that form inclusion complexes with actives and fragrances to improve their stability, solubility, and skin delivery; distinct from the chemically modified Hydroxypropyl Cyclodextrin.

Encapsulates fragrance and active ingredients to improve stability and controlled releaseImproves solubility of poorly water-soluble activesReduces irritation potential of encapsulated actives
Other
Cymbopogon Citratus Extract

An extract from Cymbopogon citratus (West Indian lemongrass), distinct from the Cymbopogon schoenanthus (camel grass) entries in the KB; contains citral and flavonoids and is used for its refreshing scent and antioxidant properties, though its citral content carries sensitization risk.

Fragrance ingredientSoothing agentAntimicrobial agent
Refreshing citrus-herbal scent from natural citral contentAntioxidant flavonoids and phenolic acidsMild antimicrobial activity
Contains citral, a regulated EU fragrance allergen (Annex III); may cause sensitization or phototoxic reactions at high concentrationsPatch test recommended for sensitive skin
Other
Cystine

The oxidized dimer of cysteine formed by a disulfide bond between two cysteine molecules; used in cosmetics as a conditioning amino acid with roles in keratin integrity and as a precursor to antioxidant glutathione — distinct from cysteine (the monomer free thiol form).

Other
Dehydroxanthan Gum

A modified form of xanthan gum where the side-chain carboxyl groups have been partially dehydrated, altering its electrolyte tolerance and rheological behavior. While standard xanthan gum can thin out in high-ionic-strength formulations (with electrolytes like salts, acids, or certain actives), dehydroxanthan gum maintains viscosity across a broader range of ionic conditions. Provides a cleaner, more elegant texture than conventional gums in lightweight K-beauty formulas.

Modified xanthan gum that performs well in high-salt/electrolyte formulations where standard xanthan gum loses viscosityCreates a lightweight, non-sticky gel texture preferred in serums and essence formulasImproves formula elegance — less stringy and more water-like feel than standard xanthan gum at equivalent viscosity
