PEG-60 almond oil is a polyethylene glycol derivative of almond oil, where "PEG-60" indicates that the polyethylene glycol chain has an average of 60 repeating ethylene glycol units [2]. This modification enhances the water solubility of almond oil, making it suitable for various cosmetic formulations.
The production process of PEG-60 almond oil involves reacting almond oil with polyethylene glycol. First, almond oil, typically obtained from the kernels of sweet almonds (Prunus amygdalus dulcis), is refined. This refined oil then undergoes ethoxylation [3], where ethylene oxide is added to the oil in the presence of a catalyst, resulting in the polyethylene glycol modification. The number "60" in PEG-60 signifies the average number of ethylene oxide units added to the almond oil molecule [4].
PEG-60 almond oil functions as an emulsifier by helping to mix oil and water-based ingredients, creating stable and homogenous formulations [5]. It also acts as an emollient, providing a smoothing and softening effect on the skin [6]. As a surfactant, it helps to reduce the surface tension of liquids, aiding in cleansing and foaming properties [7].
PEG-60 almond oil is used as a solubilizer in products, such as facial cleansers, body washes, shampoos, and lotions, where the incorporation of oil-based ingredients is necessary [8]. Its emulsifying properties make it useful in creams and lotions to ensure a uniform texture and prevent separation [9]. Additionally, it can be found in hair care products to provide conditioning benefits [10].
PEG-60 almond oil is typically packaged in airtight containers to prevent moisture absorption and maintain its quality. Transportation should adhere to standard practices for liquid chemicals, avoiding extreme temperatures and direct sunlight [11]. Proper labeling, including safety and handling precautions, is required during shipping.
