Material base de éster sintético biodegradable que se prepara a partir de: 60-99% en peso de por lo menos un material base de éster sintéticobiodegradable que comprende el producto de reacción de: un alcohol lineal o ramificado que tiene lafórm ula general: R(OH)n, donde R es un grupo alifáticoo cicloalifático que tiene desde aproximadamente 2 a 20 átomos de carbono y n es por lo menos 2; y por lo menos un oxo ácido ramificado que tiene un númerode carbono en el rango de entreaproximadam ente C5 a C10 con la condición de que dicho oxo ácido ramificado no incluye ácido 2-etilhexanoico; donde elmaterial base de éster exhibe las siguientes propiedades: por lo menos 60% de biodegradación en 28 días medido por el ensayoModificado de Sturm; un puntode fluidez de menos de -25*C, y una viscosidad de menos de 7500 cps a -25*C; aproximadamente 1 a 20% en peso del paquete aditivo lubricante, yaproximadamente 0 a 20% de un solvente. Se describe además un lubricantesintético que se prepara a partir de dicho material base.
