Published: with international search report (Art. 21(3)) (54) Title: RENEWABLE, BIODEGRADABLE MARKING WAX COMPOSITION (57) : The present disclosure is directed to marking compositions that are derived from environmentally friendly, biodegrad- able, and sustainable resources. Such compositions may be formulated in to writing and/or drawing instruments such as crayons. In various embodiments, the marking compositions include one or more of a structural component, a stiffening and/or laydown component, and a colorant. For instance, the structural component may be an ester wax composed of a diol and diacid, such as where the diols and diacids contain about 2 to about 14 carbon atoms each, such as where the structural component is present in an amount of from about 10% by weight to about 90% by weight, such as about 20% to about 80%, including about 60% of the composition. Additionally, the stiffening and/or lay down component may be a bifunctional fatty acid, such as stearic acid, which may be included in the composition, such as a stiffening agent as well as to enhance smoothness of laydown. A typically useful amount that may be used ranges from about 20% or less to about 80% or more, such as about 40% to 60% or more by weight of the composition. Further, in various embodiments, a naturally occurring, organic colorant may be provided as part of the marking composition.
