The animals were separated into four groups of 60 (30 males and 30 females per group). Polybutene is safe to use, because it is non-toxic. Indopol polybutenes are synthetic hydrocarbon polymers made by polymerization of C4 olefins (primarily isobutene) and are available in a wide range of viscosities. As is well known from cracker-based chemistry, cationic chain polymerization of isobutene yields the homopolymer polyisobutene (PIB), while copolymerization of about 98% isobutene with about 2% isoprene yields butyl rubber.

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: . You may need to do some re-formulating rather than doing a straight one-for-one swap; you might consider adding some lanolin to get a bit of the tacky richness youll be missing from the polybutene. Due to its high molecular weight, polybutene does not tend to crack when subject to stress and therefore gives the elastic raw material a high level of flexibility.
