“…Moreover, by testing the formulated blends (3)(4)(5)(6)(7)(8) and (9)(10)(11)(12)(13)(14), it can be concluded that all the formulated blends confirm the other specifications of petrolatum according to the definition of US Pharmacopoeia & National Formulary (Table 6). aromatics free wax is produced with lower congealing point than that of microcrystalline wax.…”

“…Alexandria crude petrolatum was subjected to one stage fractional crystallization (deoiling process) [12][13][14] using butyl acetate (BA) solvent at fixed solvent feed ratio of 8:1 for dilution and 2:1 (S/F, by weight) for washing and at ambient fractionating temperature of 20 o C. In this technique, the high melting components of the wax (hard wax) got precipitated while the low melting ones (soft or slop wax) remained in the solution.…”

Deoiling of crude petrolatum was intensified by addition of 1 wt.% of non-polar modifier concentrates separated from slack wax waste and compared with pure n-alkane mixtures;(C 20 +C 22 ) and (C 24 +C 26 ). Data revealed that, 1 wt.% of the separated (C 20 +C 22 ) n-alkane mixture is selected as the preferable modifier to intensify and improve the deoiling process of crude petrolatum. X-ray diffraction patterns and SEM photographs observed that, the addition of 1 wt.% of non-polar modifier concentrates gave hard waxes having somewhat crystal growing and higher crystal sizes and possess more holes than the hard waxes separated without using a modifier. Different petroleum products were produced by using both the products of petrolatum deoiling process; the microcrystalline wax and the slop wax. Various grades of hardened ceresin were formulated by addition of low density poly ethylene with the separated microcrystalline wax. Fourteen formulated blends of petrolatum were prepared based on the microcrystalline wax and slop wax saturate with heavy and light paraffin oils, respectively. According to the standard specifications of US Pharmacopoeia and National Formulary of petrolatum and Ultra Chemical Inc. of liquid petrolatum, the blend formulations (3-8) are classified as technical petrolatums. Meanwhile, two of them (7 & 8) are classified also as liquid petrolatums. The blend formulations (9-14) are classified as white pharmaceutical petrolatums. Meanwhile, three of them (12-14) are also within the limits of standard specifications of ultrapure liquid petrolatums.

“…Our previous study revealed that some grades of paraffin waxes can be produced by fractional crystallization of light, middle and heavy slack waxes at ambient temperature by using different solvents. Also, the most suitable solvents for separating paraffin waxes are ethyl and butyl acetates, MIBK and the mixture of MEK, B & T (60:20:20 by weight, respectively) [7]. In another research, the differentiation between fractional crystallization and solvent percolation technique was studied for separation of paraffin waxes from light, middle and heavy slack waxes.…”
