Stem Extract

Piper methysticum leaf/root/stem extract is the cosmetic ingredient name for a material derived from the leaves, roots, and stems of the Piper methysticum G. Forster plant, commonly known as kava kava. This and other kava-derived ingredients are used as skin-conditioning agents at concentrations from 0.0001% to 0.1%. The Food and Drug Administration issued a consumer advisory in 2002 expressing concern about liver damage in individuals who have ingested kava products. The available oral toxicity data support the concern about liver damage on ingestion but do not resolve the question, for example, whether these ingredients would be substantially absorbed through the skin. Other data needs are described, including toxicology data for yangonin, methysticin, and kavain, which may be present in kava-derived ingredients. Accordingly, the available data are insufficient to support the safety of these ingredients in cosmetics.

Patch Tests

Glyceryl Ricinoleate is the monoester of glycerol and ricinoleic acid. Castor oil contains 87–90% Glycerol Ricinoleate. Ricinoleic acid is metabolized by both β-oxidation and α-oxidation. Acute oral toxicity tests in mice indicated that Glyceryl Ricinoleate has an LD50 greater than 25.0 ml/kg and is, at most, mildly irritating to unrinsed rabbit eyes. This ingredient was not a primary skin irritant. Castor oil was nonmutagenic by the Ames test. Ricinoleic acid was not a carcinogen when tested in mice. In human single-insult occlusive patch tests, no indication of skin irritation potential was observed in the two products containing 5.6% Glyceryl Ricinoleate. The available data on Glyceryl Ricinoleate were insufficient to determine whether this ingredient, under each relevant condition of use, was either safe or not safe. The types of data required before a decision can be made include: (1) 28 day chronic dermal toxicity in guinea pigs, and (2) clinical sensitization and photosensitization studies (or an appropriate ultraviolet spectrum instead of the photosensitization data).

Reproductive Study

Polyacrylamide is a polymer of controllable molecular weight formed from the polymerization of acrylamide monomers. Average concentrations of the monomer were reported as less than 0.01% by several manufacturers. Polyacrylamide is used as a foam builder and stabilizer in shampoo products and as a vehicle in sunscreen preparations. An acute oral toxicity study of Polyacrylamide in rats reported that a single maximum oral dose of 4.0 g/kg body weight was tolerated. In a subchronic oral toxicity study in both rats and dogs, animals were given a maximum dose of 464 mg/kg body weight, with no signs of toxicity in any animals. Two separate studies in rats reported no absorption when the compound was administered by gavage. In a 2-year chronic oral toxicity study, rats fed between 500 and 10,000 ppm in their diet had no significant adverse effects. Similar results were obtained in dogs. A 2-year feeding study in rats fed up to 5.0% Polyacrylamide reported no significant adverse effects. Cutaneous tolerance tests performed to evaluate the irritation of Polyacrylamide indicated that the compound was relatively well tolerated. Undiluted Polyacrylamide applied to the conjunctival sac of the rabbit caused a very slight response. No compound-related lesions were noted in a three-generation reproductive study in which rats were fed either 500 or 2000 ppm Polyacrylamide. On the basis of data presented in this report, it is concluded that Polyacrylamide, with less than 0.01% acrylamide monomer content, is safe as a cosmetic ingredient as currently used.

Aminomethyl propanol and aminomethyl propanediol are substituted aliphatic alcohols that function as pH adjusters in cosmetic products at concentrations less than 10%; additionally, aminomethyl propanediol is a fragrance. Extensive oral toxicity data are reviewed, with fewer inhalation toxicity data. Dermal toxicity data are presented that demonstrate, for example, that a mascara with 1.92% aminomethyl propanediol does not cause dermal irritation or allergic contact sensitization, suggesting that the maximum reported use concentration of 2% in mascara would be safe. Although these ingredients are primary amines that are not substrates for N-nitrosation, they may contain secondary amines as impurities in finished products that may undergo N-nitrosation. These ingredients should not be included in cosmetic formulations containing N-nitrosating agents. The Cosmetic Ingredient Review Expert Panel concludes that aminomethyl propanol and aminomethyl propanediol are safe as cosmetic ingredients in the practices of use and concentrations as described in this safety assessment.

The 7 Stearates described in this report are either oily liquids or waxy solids that are primarily used in cosmetics as skin emollients at concentrations up to 25 percent. The toxicology of the Stearates has been assessed in a number of animal studies. They have low acute oral toxicity and are essentially nonirritating to the rabbit eye when tested at and above use concentration. At cosmetic use concentrations the Stearates are, at most, minimally irritating to rabbit skin. In clinical studies the Stearates and cosmetic products containing them were at most minimally to mildly irritating to the human skin, essentially nonsensitizing, nonphototoxic and nonphotosensitizing. Comedogenicity is a potential health effect that should be considered when the Stearate ingredients are used in cosmetic formulations. On the basis of the information in this report, it is concluded that Butyl, Cetyl, Isobutyl, Isocetyl, Isopropyl, Myristyl, and Octyl Stearate are safe as cosmetic ingredients in the present practices of use.

Available Information

Polybutenes are the isotactic polymers of isobutene and n-butene. Polybutenes provide viscosity or emulsifiability to more than 80 cosmetic products in concentrations up to 50%. The results of acute oral and percutaneous toxicity tests of Polybutenes show these materials to be relatively harmless. Acute skin irritation tests on rabbits showed no or mild irritation. Other test results indicate that Polybutenes are not toxic: (a) there were no observable effects in rats after inhalation at concentrations up to 18.5 mg/l of air; (b) there was only mild, transient eye irritation in rabbits; (c) intravaginal application of concentrated Polybutene daily for 30 days produced no observable effect in rabbits. Chronic oral toxicity in rats fed up to 20,000 ppm for three successive generations showed no impairment in reproduction. The available human clinical data indicated only very mild effects. Skin tests for sensitization, irritancy, phototoxicity, and photosensitization were limited to cosmetic formulations. On the basis of the available information, it was concluded that Polybutenes are safe as presently used in cosmetics.

Hydroxybenzomorpholine (HBM) is a heterocyclic compound that is used in cosmetics as a coupler in coal tar hair dyes. No deaths were reported in a subchronic oral toxicity study in rats. Some degenerative changes in the cortical tubules of the kidneys were observed in the mid and high-dose groups. HBM was considered to be practically nonirritating to the rabbit eye and produced only slight skin irritation. HBM was neither a sensitizer nor a photoallergen. HBM was not mutagenic in either the Ames assay or in the mouse micronucleus test. On the basis of the data included in the report, Hydroxybenzomorpholine is considered to be safe as a hair dye ingredient at the current concentrations of use.

The steareth group is a series of compounds prepared by reacting stearyl alcohol with ethylene oxide to form polyoxyethylene stearyl ethers. Steareths are waxy solids used primarily as emulsifiers in cosmetics at concentrations of up to 25%. Steareth-2 and-10 were nontoxic to rats in acute oral toxicity studies. In subchronic testing, steareth-20 was nontoxic to rabbits when administered dermally at concentrations of 4%. Steareth-2 and-10, at concentrations of up to 60% in water, were at most mildly irritating to rabbit eyes and only mild irritants when tested in cosmetic formulations at concentrations of up to 60%. Structurally similar polyoxyethylene alkyl ethers were neither mutagenic nor tumor promoters. Steareth-2,-10, and-20 in water were neither primary irritants nor sensitizers to human skin. Steareth-20 was not phototoxic. On the basis of the available data it is concluded that steareths-2,-4,-6,-7,-10,-11,-13,-15, and-20 are safe as cosmetic ingredients in the present practices of use and concentration.

Glyceryl Stearate and Glyceryl Stearate/SE are the esterification products of glycerine and stearic acid, and are used in cosmetic formulations as emollients, emulsifiers, and stabilizers. In acute oral toxicity studies in rats, both ingredients were slightly toxic. Glyceryl Stearate in the diet of rats for three consecutive generations had no adverse effects. Five percent Glyceryl Stearate did not promote the carcinogenicity of DMBA in mouse skin. In subchronic and chronic dermal toxicity tests, Glyceryl Stearate was nontoxic to rabbits but did cause moderate irritation. Primary eye irritation studies, at concentrations up to 100%, were mildly irritating or nonirritating to rabbits. Single and Repeated Insult Patch Tests showed both ingredients to be nonsensitizing and nonirritating. Products containing 2% Glyceryl Stearate were nonphototoxic and nonphotoallergenic. On the basis of the available data, it is concluded that Glyceryl Stearate and Glyceryl Stearate/SE are safe for topical application to humans in the present practices of use and concentration.

The Individual

Tallow, Tallow Glyceride, Tallow Glycerides, Hydrogenated Tallow Glyceride, and Hydrogenated Tallow Glycerides are used in eye and face makeup preparations and in skin care preparations. Concentrations of use range from ≤0.1 % to > 50%. The fatty acid constituents of Tallow, and some of the corresponding fatty acid alcohols have been evaluated for safety by the Federation of American Societies of Experimental Biology, the Food and Drug Administration, and by an Expert Panel of the Cosmetic Ingredient Review. In all cases, the ingredients were found safe in present practices of use. None of these constituents of Tallow were toxic through oral and dermal exposure, they were not ocular or dermal irritants, and they were neither dermal sensitizers nor photosensitizers. The same was true for other oils which contain varying concentrations of the constituents of Tallow. Based on the CIR safety evaluations of the individual constituents of Tallow and of cosmetic ingredients containing the constituents of Tallow, and on the approval of Tallow for use in foods and other consumer products, it is concluded that Tallow, Tallow Glyceride, Tallow Glycerides, Hydrogenated Tallow Glyceride, and Hydrogenated Tallow Glycerides are safe as cosmetic ingredients in the present practices of use.
