PPG-12 Buteth-16

What is PPG-12 Buteth-16?

PPG-12-Buteth-16 is a nonionic polyalkylene glycol ether produced by reacting butanol with 12 moles of propylene oxide followed by 16 moles of ethylene oxide, yielding a molecule with balanced hydrophilic and lipophilic properties. This ethoxylated-propoxylated alcohol serves as a multifunctional ingredient in rinse-off and leave-on personal care products like shampoos, conditioners, cleansers, and lotions. It operates by reducing interfacial tension between oil and water phases to form stable emulsions, dispersing hydrophobic substances such as fragrances and oils into aqueous bases for uniform delivery, and providing light conditioning through surface modification. The propylene oxide block imparts oil solubility and emolliency, while the ethylene oxide chain enhances water dispersibility, resulting in improved product clarity, spreadability, and mild sensory enhancement without heavy residue.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Fragrance ingredient
Contributes scent character and/or masks base odors, shaping the overall sensory experience of the formula (subject to allergen and IFRA considerations).
Hair conditioning
Improves softness, shine, and manageability by reducing friction and static; commonly achieved with cationic agents, silicones, oils, or conditioning polymers.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Solvent
Dissolves and carries other ingredients, helping control viscosity, evaporation rate, and delivery of actives in both water- and oil-based systems.
Surfactant
Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.

Benefits

Facilitates blending of oils and water for stable, smooth-textured products.

Solubilizes fragrances effectively, enhancing scent profile in formulas.

Provides mild conditioning to soften hair and skin surfaces.
