Formula IngredientAbsorbent, Chelating AgentCyclodextrin
INCI: Cyclodextrin
Cyclodextrin is a ring-shaped carbohydrate (cyclic oligosaccharide) derived from natural starch (typically corn or potato) through enzymatic breakdown. Its distinctive donut-shaped structure has a hydrophilic outer surface and a lipophilic hollow inner cavity, allowing it to encapsulate other molecules — trapping actives, fragrances, or oils without altering their structure. In cosmetics it functions as both an absorbent (reducing excess oil and sweat) and a chelating agent (binding metal ions that can destabilise formulations or trigger irritation).

sebum absorption, mattifying, oil control, formula stabilisation, chelating metal ions, controlled release of encapsulated actives, fragrance retention, improved solubility of poorly soluble compounds
Is Cyclodextrin safe? Key considerations
Can Cyclodextrin cause irritation?
Low RiskGenerally considered non-irritating at typical cosmetic use concentrations (0.1–5%). Rare cases of mild irritation or temporary tightness have been reported in very sensitive skin. Individuals with known corn or potato starch sensitivities should patch test. No EU Annex II or III restrictions apply to cyclodextrin.
Does Cyclodextrin increase sun sensitivity?
No RiskCyclodextrin does not increase photosensitivity. No sun protection precautions are required specifically for this ingredient, though SPF is always recommended as part of a daytime routine.
Is Cyclodextrin safe during pregnancy?
SafeNo known risks identified for topical use. Animal studies on oral administration at doses below 600 mg/kg showed non-toxic profiles. Topical absorption is minimal. Limited specific human pregnancy data exists, so consulting a healthcare provider is recommended as a precaution (source: Motherfigure/toxicity literature).

Individuals with known allergy to corn or potato starch derivatives (rare) should review the considerations above before use.
