Due to its properties, this derivative of the rapeseed oil and glycerol, with the INCI name PEG-17 Rapeseedamide, is used as an additive for laundry detergents, an emulsifier in lubricating compositions and also an auxiliary substance for household chemicals. It is an ingredient of hair shampoos, hair conditioners and body lotions.
A mixture of ethoxylated acid amides of rapeseed oil and ethoxylated glycerol is a substance with the INCI name PEG-17 Rapeseedamide. The CAS number of the compound is 221045-17-6. As an ingredient of products, it acts as an emulsifier and foaming agent.
PEG-17 Rapeseedamide is in the form of a liquid or, less frequently, an easily spreadable paste that is light brown to brown. The molar mass of the substance is approx. 1100 g/mol. It displays unlimited water solubility and is also soluble in organic solvents such as acetone, ethanol or benzene. pH of 1% aqueous solution ranges from 7.5 to 10.5 (neutral to slightly alkaline). PEG-17 Rapeseedamide boils at a temperature above 220ᵒC (the substance also decomposes above this temperature). Its solidification point is in the range of 15 to 25ᵒC.
PEG-17 Rapeseedamide has emulsifying properties. It also acts as a co-emulsifier. It enhances and boosts the effect of other emulsifiers that are included in an emulsion. In particular, PEG-17 Rapeseedamide enhances the effect of such emulsifiers that are responsible for generating emulsions in O/W (oil-in-water) systems with waxes and mineral oils.
In mixtures with anionic surfactants, it is a substance that stabilises andimproves the quality of foam. As a stabiliser, it prevents emulsion breaking, thus preventing the deterioration of its performance. PEG-17 Rapeseedamide facilitates the generation of large quantities of stable foams. Foam generated by surfactants such as PEG-17 Rapeseedamide plays a crucial role in the mechanism of removing impurities from a surface. The compound is an ingredient of dedicated products for washing the scalp and hair that have re-lubricating properties. Thus formulations containing PEG-17 Rapeseedamide have the ability to restore the natural lipid barrier of the skin.
The advantages of PEG-17 Rapeseedamide undoubtedly include the emulsifying and stabilising effects (improving the foam quality). As an ingredient of numerous body and hair care products, it improves their effectiveness and performance.
Moreover, logistic processes and operations aimed at processing PEG-17 Rapeseedamide are relatively low demanding. The liquid form of the surfactant is definitely advantageous as it eliminates the need to heat up the whole formulation (many active substances are sensitive to elevated temperatures).
Another advantage is that PEG-17 Rapeseedamide is a derivative of rapeseed oil with an increased shelf life than derivatives based on coconut oil or palm kernel oils.
