PEGs are polyethylene glycol derivatives resulting from a polycondensation reaction and, depending on the structure of the derivative molecule, have specific applications in cosmetic products. PEG-11 Castor Oil is a castor oil derivative. It is used as an ingredient of anti-wear agent, lubricants and cutting fluids. It is readily chosen by formulators in industrial branches due to its physical form and a number of advantages.
PEG-11 Castor Oil is a non-ionic surfactant that is an ethoxylated derivative of castor oil. PEG-11 Castor Oil is the name of the compound according to the international INCI system. The CAS number of the compound is 61791-12-6.
The pure substance comes as a bright and clear liquid (at the room temperature) with a characteristic odour. Its molar mass is approx. 714 g/mol. PH of a 1% aqueous solution of PEG-11 Castor Oil ranges from 5.0 to 7.0 (slightly acidic to neutral reaction). The surfactant dissolves very well in water and also in low aliphatic alcohols (methanol, ethanol). The density of PEG-11 Castor Oil at 20ᵒC is approximately 1.08 g/ml. Its solidification point does not exceed 15ᵒC. The compound is easily biodegradable in the natural environment. It is moderately resistant to acidic media.
PEG-11 Castor Oil is a surfactant readily chosen by formulators in industrial branches. The reason is a number of properties and advantages that characterise the substance, including its physical form and ease of biodegradation in the natural environment.
PEG-11 Castor Oil features the power to emulsify conventional base oils and oils of natural origin. The molecular structure directly determines its capacity to combine phases that are mutually immiscible. Moreover, the compound exhibits a very good solubility of most mineral and vegetable oils. On that account, it is used as an agent that improves lubricating properties and also as an anti-wear additive. Such preparations that contain PEG-11 Castor Oil are popular in weaving processes. They boost the efficiency of processes and prevent excessive degradation of machine parts. PEG-11 Castor Oil is also an ingredient of cutting fluids used in the processing of metal elements. The fluids are based on soluble oils, semi-synthetic coolants and neat oils. Their main task is to carry away the heat produced while metal elements rub against each other. The mining industry also readily uses solutions that employ PEG-11 Castor Oil. The surfactant is present in fire resistant hydraulic fluids of the HFA type. Another use of PEG-11 Castor Oil is pesticide formulations, such as mainly EC, SC, EW and ME.
