ABSTRACT: An earlier safety assessment of several cellulose polymers has been expanded to include cellulose itself and other cellulose polymers used in cosmetics. In general, these ingredients are modified cellulose polymers formed by reaction with the free hydroxyl groups in cellulose. The number of hydroxyl groups reacting, as well as the nature of the substitute group, largely determine the physical properties, particularly solubility, of the product. These ingredients are used in a wide variety of cosmetics as thickeners, suspending agents, film formers, stabilizers, emulsifiers, emollients, binders, or water-retention agents. These ingredients do not appreciably penetrate the skin barrier. Cellulose and its polymers pass essentially unchanged through the gastrointestinal tract following oral administration and are practically non-toxic. Ocular and dermal irritation studies indicate, at most, minimal irritants and not sensitizers. These ingredients are considered safe as cosmetic ingredients in the practices of use and concentration given in this safety assessment.ionlgjicn
CONCLUSION: On the basis of the data presented in this report, the CIR Expert Panel concludes that Cellulose, Calcium Carboxymethylcellulose, Carboxymethyl Cellulose Acetate Butyrate, Carboxymethyl Hydroxyethylcellulose, Cellulose Acetate, Cellulose Acetate Butyrate, Cellulose Acetate Propionate Carboxylate, Cellulose Gum, Cellulose Acetate Propionate, Cellulose Succinate, Cetyl Hydroxyethylcellulose, Ethylcellulose, Hydrolyzed Cellulose Gum, Hydroxybutyl Methylcellulose, Hydroxyethylcellulose, Hydroxyethyl Ethylcellulose, Hydroxypropylcellulose, Hydroxypropyl Methylcellulose, Hydroxypropyl Methylcellulose Acetate/Succinate, Methylcellulose, Methyl Ethylcellulose,Methyl Hydroxyethylcellulose, Microcrystalline Cellulose, Potassium Cellulose Succinate, and Sodium Cellulose Sulfate are safe as cosmetic ingredients in the practices of use and concentration given in this safety assessment.
