瑞安勃对环境负责的生物基润滑油是配方自可再生的农业资源，他们的低毒性，生物降解性是必然的。瑞安勃的可降解润滑油配方根据ASTM D–5864嗜氧生物降解润滑油标准已经经过了评估和广泛的生物降解测试（已进行了超过40种生物研究），其最终可降解PW1（ASTM可降解测试的最高等级）和达到并超过了美国鱼类和野生动物管理署和美国环保局EPA的毒性测试（LC- 50）标准。
Renewable Lubricants’ Biobased Products are environmentally responsible lubricants that are formulated from renewable agricultural resources. They should be especially used where low toxicity and biodegradability properties are required. Renewable Lubricants’ bio-formulas have been evaluated and extensively tested as Biodegradable according to ASTM D-5864 Aerobic Aquatic Biodegradation of Lubricants (over 40 bio-studies have been performed), and when noted, are Ultimate Biodegradable Pw1, (ASTM’s highest rating) and meet/exceed the acute toxicity (LC-50) criteria adopted by the U.S. Fish and Wildlife Service and the U.S. EPA. The bacterial microorganisms used in biodegradation tests are some of the simplest forms of life, and like all living organisms, are adversely affected by the presence of chemical toxins. The low toxicity of these biobased products is demonstrated by the microorganism’s ability to multiply and biodegrade Renewable Lubricants’ Biobased Products in ASTM D-5864 biodegradation studies.
