PPG-9 BUTYL ETHER.

Valuable CAS 9003-13-8 / HAIR CONDITIONING, SKIN CONDITIONING

PPG-9 Butyl Ether functions as a versatile skin and hair conditioning agent, designed to enhance the skin's appearance by reducing flaking and restoring suppleness. It forms a protective, moisturizing film, providing a smooth, silky feel while also acting as a solvent and solubilizer within formulations.

Science

Mechanism of Action

This ingredient operates by creating a fine, protective film on the skin's surface, effectively minimizing transepidermal water loss and thereby preserving moisture. This action diminishes flaking and imparts a softer texture, contributing to improved skin hydration and appearance. Additionally, it serves to dissolve other components in a formula, ensuring product stability and aesthetics.

Key findings

  1. 01 Clinical studies involving PPG BE800 (an average molecular weight of 800 PPG Butyl Ether) at concentrations from 0.001% to 0.26% demonstrated non-carcinogenic, non-irritating, and non-sensitizing properties in both rats and 200 human subjects. Similarly, PPG-14 Butyl Ether, typically used between 0.1% to 1%, was found not to cause significant skin irritation. However, it is critical to note that PPG-9 Butyl Ether, being a smaller molecular weight variant, has a greater potential for skin absorption and subsequent irritation, requiring precise formulation to ensure efficacy without adverse effects.

Stability

Due to its smaller molecular weight, PPG-9 Butyl Ether has a higher potential for skin absorption and irritation compared to larger PPG Butyl Ethers. Therefore, it must be meticulously formulated to avoid adverse skin reactions, especially at higher concentrations.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PPG-9 Butyl Ether, along with other PPG Butyl Ethers, is safe for cosmetic use when formulated to prevent irritation. This restriction is paramount for smaller PPG Butyl Ethers like PPG-9, which are noted for their greater skin absorption potential and associated irritation risk, as indicated by toxicity data. While the EU Cosmetic Regulation allows its use under general provisions, no specific SCCS opinion for PPG-9 Butyl Ether has been found.
