PPG-2-BUTETH-1.

Valuable CAS 9038-95-3 / 9065-63-8 / HAIR CONDITIONING, SKIN CONDITIONING

PPG-2-BUTETH-1 is a multifunctional ingredient primarily recognized for its skin and hair conditioning properties. It also functions as a versatile solvent, emulsifier, and surfactant, aiding in product formulation and enhancing sensory feel.

Summary

Skin conditioning Hair conditioning Solvent Emulsifier Surfactant Solubilizer

Science

Mechanism of Action

This ingredient acts as a skin conditioning agent by forming a protective film on the skin's surface, which helps to reduce flaking, restore suppleness, and maintain hydration by lubricating the skin. As a solvent, it dissolves other ingredients in a formulation. Additionally, its surfactant and emulsifying capabilities reduce surface tension, effectively blending oil and water-based components and acting as a solubilizer for various substances.

Stability

PPG-2-BUTETH-1 exhibits chemical stability under standard conditions of use, largely attributed to its robust ether linkages. However, its integrity can be compromised by exposure to elevated temperatures, extreme pH environments (outside a range of approximately 4.0-7.0, based on a related ingredient PPG-26-Buteth-26), or ultraviolet (UV) radiation. Such conditions may induce degradation pathways like chain scission, oxidation, or hydrolysis, leading to the formation of lower molecular weight byproducts.

  • High temperatures
  • UV radiation

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed PPG Butyl Ether ingredients, including PPG-2-BUTETH-1, safe for use in cosmetics when formulated specifically to prevent irritation. While some clinical assessments on related compounds reported no irritation or sensitization, specific toxicity data for PPG-2 Butyl Ether indicated it could cause minor, transient erythema, desquamation, and ocular irritation. Formulators should also address the potential for trace amounts of 1,4-dioxane, a by-product, through purification. The FDA has approved PPG Buteth ingredients as indirect food additives.
