Dekametilciklopentasiloksan je organsko jedinjenje, koje sadrži 10 atoma ugljenika, ima molekulsku masu od 370,770 Da i spada u hemijsku grupu silikona.

Silikoni su sintetički polimeri koji se koriste u kozmetici za poboljšanje stanja kose i kože. Postoje različite vrste silikona, a svi imaju karakteristike koje im omogućuju da se lako rašire po koži ili kosi i stvore paropropusni film. Silikoni su nerastvorljivi u vodi i imaju nizak površinski napon, zbog čega se koriste za poboljšanje negujućih svojstava u proizvodima za negu kože i kose. Dekametilciklopentasiloksan se mora koristiti u kozmetičkim proizvodima samo u malim količinama zbog ekoloških razloga. Evropski stručnjaci su preduzeli mere da ograniče njegovo ispuštanje u vode zbog njegove postojanosti i bioakumulativnosti.
