Science
Mechanism of Action
This ingredient operates through its amphiphilic structure, possessing both water-loving (polyethylene glycol) and oil-loving (Shorea Butter glycerides) components. This allows it to act as an effective emulsifier, preventing the separation of oil and water phases within a product. As a lightweight humectant, it draws and binds moisture to the skin, boosting hydration. It also forms a thin, protective emollient layer, which minimizes transepidermal water loss and leaves dry or rough skin feeling soft and smooth. Additionally, the Shorea butter constituents contribute to mitigating potential irritation often associated with other cleansing agents, ensuring a gentle interaction with the skin.

The Formula
Formulation
Stability
Derived from Shorea Butter, known for its high oxidative stability and uniform triglyceride composition, this ingredient contributes to robust formulation stability. It can be directly dispersed in water to yield a cloudy liquid without precipitation, offering flexibility in formulations and potentially reducing the need for additional emulsifiers.
Synergies
- Works synergistically with other surfactants to enhance gentle cleansing properties.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed PEGylated alkyl glycerides, including PEG-75 Shorea Butter Glycerides, safe for use in cosmetics when formulated to be non-irritating, with typical usage concentrations ranging between 0.01% and 5%. However, a critical caution exists for PEG-based ingredients: they should not be applied to compromised or damaged skin (e.g., burn patients) due to documented evidence of sensitization and potential nephrotoxicity in such specific clinical contexts.
