“…Because of its high viscosity, it is used as a lubricant in two-stroke engines, neat or blended, reducing smoke emissions by up to 50-70% [113,114]. It is a polyol that can readily form polymers making polyurethanes that find applications in adhesives and coatings, electrical insulators, and semirigid foams used in thermal insulation [115]; it was also suggested as a possible candidate biomaterial for wound dressings [116] and as a graft for bone defect treatments [117]. The so-called Turkey red oil, produced by CB oil sulfation, is widely used in textile industries in dyeing and in finishing cotton and linen [118].…”

“…Obtained by a different method, the polyurethane produced by Poliquil® is marketed under the name of Ricinus Bone Compound (COR). Leonel et al [ 17 ] describe that the synthesis took place from a diisocyanate (Diphenylmethane diisocyanate/MDI) reaction with a polyol derived from castor oil for the synthesis of the prepolymer. The polymerization occurred by the reaction between the prepolymer and polyol in a ratio of 1:0.65 of prepolymer and polyol, with the addition of calcium carbonate, considered a biocomponent reaction.…”

“…Similar results of a polyurethane FTIR were found by Zhang et al [ 18 ] when investigating the effects of the molar ratio of castor oil polyols on polyurethane structure and properties, noting that hydrogen bonds affect them [ 13 18 , 20 , 22 ]. The polyurethane of the company Poliquil® has excellent structural properties, which gives it compatibility with living tissues, does not release vapors and toxic radicals when implanted [ 17 ]. Similar data is given to polyurethane produced at UFPI, based on this research results, a pioneering study with this product, since it is biocompatible, osteoconductive, and osteointegrable.…”

“…Аутогенна кістка вважається золотим стандартом кісткової пластики альвеолярного відростка верхньої щелепи у дітей з вродженим незрощенням губи і піднебіння (ВНГП) через її остеоіндуктивні, остеокондуктивні і остеогенні властивості. ЇЇ класифікують за походженням: інтрамембранального типу -мезенхімального походження (всі кістки черепа); ендохондрального типу -ендомезенхімального похо-дження (великогомілкова кістка і гребінь клубової кістки) [1,4,[11][12][13][14]. Багато вітчизняних та закордонних дослідників використовували експериментальні моделі дослідження регенерації кісткової тканини альвеолярного відростка і було доказано, що кісткові блоки мезенхімального походження (кістки черепа) на відміну від ендомезенхімального походження (великогомілкова кістка і гребінь клубової кістки), менш зазнають резорбції, швидше реваскуляризуються і регенерують в реципієнтній ділянці [2,3,[5][6][7][8][15][16][17][18].…”
