Abstract: A lubricant composition includes a biodegradable polyalkylene glycol, an inherently-biodegradable polyalkylene glycol, and a non-biodegradable polyalkylene glycol. The biodegradable polyalkylene glycol satisfies the biodegradability requirements set forth in OECD 301B. The inherently-biodegradable polyalkylene glycol satisfy the inherently-biodegradability requirements set forth in OECD 301B. The non-biodegradable polyalkylene glycol is defined by OECD 301B and satisfies the non-bioaccumulative requirements set forth in OECD 107. The lubricant composition includes the biodegradable polyalkylene glycol in an amount of at least about 30 parts by weight, the inherently-biodegradable polyalkylene glycol in an amount of from about 0.1 to about 10 parts by weight, and the non-biodegradable polyalkylene glycol in an amount of from about 0.1 to about 5 parts by weight, each based on 100 parts by weight of the lubricant composition.
