Crothix (Surf PTS 150) – PEG-150 Pentaerythrityl Tetrastearate

Crothix, also known as Surf PTS 150, is a high-performance liquid thickening and viscosity-modifying ingredient used primarily in surfactant-based cosmetic and personal care formulations. It helps increase product viscosity while improving texture, consistency, and overall product appearance.

PEG-150 Pentaerythrityl Tetrastearate functions as a thickening and stabilizing agent, making it particularly useful in shampoos, body washes, shower gels, and liquid cleansing products where a smooth and luxurious texture is desired.
