PEG-65M

Description

PEG-65M, or Polyethylene Glycol 65M, is a high molecular weight polymer derived from ethylene oxide. This versatile compound serves as a crucial ingredient in various skincare and cosmetic formulations. Its primary function is as a thickening agent and viscosity modifier, enabling products to achieve desired textures and flow characteristics.

In skincare applications, PEG-65M acts as an effective humectant, drawing moisture from the environment to the skin's surface and helping to maintain hydration. This property makes it particularly useful in moisturizers and hydrating serums. Additionally, PEG-65M enhances the stability and shelf-life of formulations by preventing separation of ingredients.

The "65M" in its name refers to its approximate molecular weight of 65,000 Daltons. This high molecular weight contributes to its ability to form protective films on the skin, which can help reduce transepidermal water loss. PEG-65M is generally well-tolerated by most skin types and is considered non-irritating and non-sensitizing.

While effective, formulators should consider potential interactions with other ingredients and its impact on product aesthetics when incorporating PEG-65M into skincare formulations.
