PPG-2 Isostearate

PPG-2 Isostearate is a synthetic emollient derived from propylene glycol and isostearic acid. It functions as a skin conditioning agent, helping to soften and smooth the skin surface by forming a light occlusive layer.In formulations, it works alongside other ingredients to improve texture and reduce water loss from the skin. It is valued in skincare for its ability to condition without leaving a greasy feel, making it suitable for a range of product types from serums to moisturisers.

PPG-2 Isostearate works by depositing a thin, occlusive film on the skin. This barrier helps to trap moisture and prevents water from evaporating from the stratum corneum, the skin's outermost layer. This mechanism is similar to other emollients, though PPG-2 Isostearate is designed to be lighter and less occlusive than heavier oils or waxes.

PPG-2 Isostearate is typically used as part of a formulated product rather than as a standalone ingredient. If you have acne-prone or fungal acne-prone skin, patch test new products containing this ingredient and observe your skin over 2–4 weeks before full integration. It can be used daily in appropriate formulations, but discontinue if irritation or breakouts develop.

Generally well-tolerated in cosmetic formulations at typical concentrations. Those with acne-prone or fungal acne-prone skin should be cautious, as some isostearate compounds have shown comedogenic potential in animal models.
