C18-29 ALKANE
Official label name (INCI name, EU glossary of cosmetic ingredient names), No 4642
- Prohibited above an impurity threshold (Annex II)
C18-29 ALKANE: Prohibited above an impurity threshold (Annex II, entry 779), under Regulation (EC) No 1223/2009. Annexes of the Regulation consulted on 21 October 2026.
Who it concerns
What official classifications and rules say for each group. A classification describes the hazard of the pure substance, not the risk of a product that contains it, which depends on the dose and the exposure.
Pregnancy and breastfeeding
No official classification covers reproduction, the unborn child's development or breastfeeding for this substance.
Babies and children
The Cosmetics Regulation sets no age-related condition for this ingredient.
Skin, eyes and allergies
No official classification for sensitisation, irritation or eye damage, and no obligation to label it as an allergen.
Environment
No official classification as hazardous to the aquatic environment and no assessment as an endocrine disruptor for the environment.
In plain words
What it is used for
Functions declared by manufacturers:
Emollient (skin conditioning): softens and smooths the skin.
Skin conditioning: maintains the skin in good condition.
What the rules say
Prohibited only if the substance contains more than 3% (w/w) DMSO extract. This content does not appear on an ingredient list.
Hazard and risk
The CLP Regulation classifies this substance as carcinogenic, category 1B (presumed effect, established mainly from animal studies).
This classification describes what the substance can cause (a hazard), not what happens when using a product (a risk): the risk depends on the dose, the form and the route of exposure (skin, inhalation, ingestion).
The CMR classification does not apply if the substance meets an impurity limit (CLP note L, for example less than 0.1% butadiene for butane): this cannot be checked on an ingredient list.

Classified hazard (CLP Regulation)
The harmonised classification is the one set by the European Union for the whole Union. H codes refer to the hazard statements of Annex III of Regulation (EC) No 1272/2008.
Distillates (petroleum), hydrotreated light paraffinic; Baseoil — unspecified; [A complex combination of hydrocarbons obtained by treating a petroleum fraction with hydrogen in the presence of a catalyst. It consists of hydrocarbons having carbon numbers predominantly in the range of C15 through C30 and produces a finished oil with a viscosity of less than 100 SUS at 100 oF (19cSt at 40 oC). It contains a relatively large proportion of saturated hydrocarbons.]
