The substances in the category are considered to be similar on the basis that they have common structures of a calcium ion varying only by the length of the fatty acid chain and the presence of unsaturated and/or hydroxyl functional groups. As a result it is expected that the substances will have similar, predictable properties. REACH Annex V, Entry 9, groups fatty acids and their potassium, sodium, calcium and magnesium salts, including C6 to C24, predominantly even-numbered, unbranched, saturated or unsaturated aliphatic monocarboxylic acids. Provided that they are obtained from natural sources and are not chemically modified, the substances included in REACH Annex V, Entry 9 are exempt from registration, unless they are classified as dangerous (except for flammability, skin irritation or eye irritation) or they meet the criteria for PBT/vPvB substances. The metal fatty acid substances in the category are therefore not expected to be hazardous. Due to the close structural similarity and the narrow range of carbon chain numbers covered in this category, the toxicity properties are expected to be predictable across the category.
The category members are exclusively produced and used directly in grease form. They have vapour pressures of less than 10 E-10 Pa and melting points above 120°C, so the potential for the generation of inhalable forms is low, also the use of the grease forms will not result in aerosols, particles or droplets of an inhalable size, so exposure to humans via the inhalatory route will be unlikely to occur.
The fatty acid calcium salts would be expected to dissociate into fatty acid anions and calcium cations. Neither the fatty acid anions nor calcium cation are considered to be systemically hazardous as described above and in the category justification document. The key experimental studies on representative salts in the category, together with relevant read across studies, supporting studies and weight of evidence assessments, confirm this lack of hazard. On this basis there is no requirement to calculate systemic DNEL values from the hazard studies. The only exception is for long term local effects on the skin, where a NOAEL for skin irritation is defined by read across from the subacute dermal toxicity study on fatty acids C18 (unsaturated) lithium salts, and for which a DNEL can be derived.
