CYCLOMETHICONE

Absent de la liste de l’annexe III de l’UE

Cyclomethicone is a generic name for a mixture of cyclic dimethyl polysiloxane compounds that conform to the formula, where n has a value between 4 and 6.

CYCLOMETHICONE est inscrit dans l’inventaire CosIng de la Commission européenne sous les catégories fonctionnelles Skin Conditioning - Emollient, Hair Conditioning, Solvent, avec le numéro CAS 69430-24-6 / 556-67-2 / 541-02-6 / 540-97-6 et le numéro CE 209-136-7 / 208-764-9 / 208-762-8. CosIng mentionne une restriction à son sujet (Entry 1388 of Annex II corresponds to D4 (Cyclotetrasiloxane). If Cyclomethicone contains D4 then entry II/1388 applies. Restricted under COMMISSION REGULATION (EU) 2024/1328. 1. Shall not be placed on the market (a) as a substance on its own; (b) as a constituent of other substances; or (c) in mixtures; in a concentration equal to or greater than 0,1 % by weight of the respective substance after 6 June 2026. [...] 3. By way of derogation: (a) for D4 and D5 in wash-off cosmetic products, paragraph 1, point (c), shall apply after 31 January 2020. For the purposes of this point, “wash-off cosmetic products” means cosmetic products as defined in Article 2(1), point (a), of Regulation (EC) No 1223/2009 of the European Parliament and of the Council (*1) that, under normal conditions of use, are washed off with water after application; (b) for all cosmetic products other than the ones mentioned in paragraph 3(a), paragraph 1 shall apply after 6 June 2027.) ; vérifiez donc l’entrée correspondante de l’annexe avant de formuler. Dans l’échantillon gratuit INCIDB, il figure sur les étiquettes de 2 produits et arrive en tête de la liste des ingrédients sur powder touch. Fulton (1989) lui attribue la note 0 sur l’échelle de comédogénicité 0–5 ; cette note est retranscrite telle quelle et constitue la seule source de notation utilisée.
