1. A bio-based binder system useful for the formation of rotary fiber insulation (for example fiberglass insulation), the system comprising:
A) an aqueous curable binder composition comprising:
(i) at least one carbohydrate;
(ii) at least one crosslinking agent; and
B) a dedust composition comprising:
(i) a blown, stripped plant-based oil having a viscosity of at least 200 cSt at 40° C., a flash point of at least 293° C., and having an acid value less than 5.0 mg KOH/gram,
wherein dedust composition B) comprises an oil-in-water emulsion, wherein a first emulsifier component is mixed into the blown, stripped plant-based oil of (i) and a second emulsifying component comprising carboxymethyl cellulose is mixed into an aqueous solution before the oil-in-water emulsion is formed by mixing the aqueous solution containing the second emulsifying component and the blown, stripped plant-based oil containing the first emulsifier component, and the first emulsifier component is selected from the group consisting of an alkoxylated fatty acid, a primary amine-based emulsifier, a secondary amine-based emulsifier, a tertiary amine-based emulsifier, and mixtures thereof; and
wherein the bio-based binder system comprises 10 part per million sulfur or less based on the weight of components A) and B), excluding water.
