Product Introduction

Polyethylene Glycol-75, commonly known as PEG-75, is a water-soluble polymer of ethylene oxide, frequently used in cosmetic and personal care products, functioning primarily as a humectant and solvent [1]. PEG-75's chemical structure consists of repeating ethylene glycol units, which contribute to its water solubility and ability to attract moisture [2]. This compound helps to keep skin hydrated and assists in dissolving other ingredients within a formulation [3].

Production Process

The production of PEG-75 involves the polymerization of ethylene oxide, a process typically initiated by an alcohol or water [4]. The reaction is carefully controlled to achieve the desired molecular weight, indicated by the '75' designation, which is an average molecular weight [5]. Following polymerization, the product undergoes purification to remove residual reactants and by-products, ensuring a high level of purity suitable for cosmetic applications [6]. This purified PEG-75 is then processed into its final form, usually a solid, ready for incorporation into various formulations [7].

Efficacy and Function

PEG-75 functions primarily as a humectant, attracting and retaining moisture to hydrate the skin [8]. Its solvent properties assist in dissolving various cosmetic ingredients, ensuring uniform distribution within formulations [9]. The compound also acts as a viscosity modifier, influencing the texture and feel of the product [10]. Due to its versatile properties, PEG-75 contributes to the overall performance and stability of cosmetic products [11].

Application Scenarios

PEG-75 is widely used in skincare products, including lotions, creams, and serums, where its humectant properties help maintain skin hydration [12]. It is also found in hair care products, such as shampoos and conditioners, aiding in moisture retention and product consistency [13]. Additionally, PEG-75 is utilized in makeup formulations, contributing to the even distribution of pigments and other ingredients [14]. Its versatility makes it a common ingredient in a broad range of cosmetic and personal care applications [15].

Packaging and Transportation

PEG-75 is generally packaged in sealed containers, such as bags or drums, to prevent moisture absorption and contamination [16]. During transportation, these containers are kept in a cool, dry environment to maintain product stability [17]. Standard safety measures are observed to prevent spills or exposure during handling [18]. Proper labeling ensures clear identification and adherence to safety guidelines throughout the shipping process [19].
