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.

Prohibition or serious classificationThe text prohibits the substance for this use, or ranks it among the most serious hazards (known or presumed carcinogenic, mutagenic or reprotoxic, identified endocrine disruptor).Worth watchingThe text sets a condition or flags a hazard worth knowing: allergen, suspected effect, condition for children, hazard to the aquatic environment.For informationOfficial information with no condition on a finished product: warning to read, irritation of the pure substance.

  • Pregnancy and breastfeeding

    No classification harmonised by the European Union covers reproduction, the unborn child or breastfeeding for this substance. This does not mean it has been judged to have no effect during pregnancy.

  • 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

    Prohibition or serious classificationThe text prohibits the substance for this use, or ranks it among the most serious hazards (known or presumed carcinogenic, mutagenic or reprotoxic, identified endocrine disruptor).

    Worth watchingThe text sets a condition or flags a hazard worth knowing: allergen, suspected effect, condition for children, hazard to the aquatic environment. Classified under the CLPEU regulation that classifies chemicals by their hazards (EC No 1272/2008). Regulation: hazardous to the aquatic environment, short term, category 1 (Aquatic Acute 1); hazardous to the aquatic environment, long term, category 1 (Aquatic Chronic 1).

    Prohibition or serious classificationThe text prohibits the substance for this use, or ranks it among the most serious hazards (known or presumed carcinogenic, mutagenic or reprotoxic, identified endocrine disruptor). ECHA has included it in the Candidate List as an endocrine disruptor for the environment.

  • Read on the label

    The Cosmetics Regulation requires no warning to be printed for this ingredient.

In plain words

What it is used for

Functions declared by manufacturers:

Emulsifying (surfactant): promotes the formation of intimate mixtures of non-miscible liquids by altering the interfacial tension.

What the rules say

No EU rule targets this ingredient specifically. It remains subject to the general rule: every product must undergo a safety assessment before it is sold (Article 10 of Regulation (EC) No 1223/2009), under the manufacturer's responsibility.

Hazard and risk

The European Union has identified it as an endocrine disruptor: a substance that alters the functioning of the hormonal system and causes adverse effects. This alone does not prohibit it in cosmetics: a legal text must add it to the annexes.

The text of the annexes

No specific rule of the EU Cosmetics Regulation names this ingredient: it is on none of its lists (prohibited, restricted, colorants, preservatives, UV filters). It may be used under the responsibility of the manufacturer, who must ensure the product is safe.

Endocrine disruptor

These lists record an evaluation, not a prohibition: in cosmetics, a substance identified as an endocrine disruptor is prohibited only if a legal text adds it to the annexes.

  • Identified as an endocrine disruptor at EU level
