Dow Solvents dipropylene glycol-LO+ – Frequently Asked Questions (FAQ)

Q1: What distinguishes dipropylene glycol-LO+ from standard dipropylene glycol?

A: Dipropylene glycol-LO+ is a low-odor, high-purity grade specifically engineered for applications where sensory profile and volatility control are critical—such as personal care formulations, air care products, and sensitive industrial cleaning systems. It undergoes additional purification to minimize volatile impurities and residual monopropylene glycol, resulting in enhanced odor neutrality and improved formulation stability.


Q2: Is dipropylene glycol-LO+ suitable for use in cosmetics and personal care products?

A: Yes—it is widely used in leave-on and rinse-off cosmetic formulations as a humectant, solvent, and viscosity modifier. Its low volatility, mild skin compatibility, and excellent solubilizing capacity for fragrances and actives make it well-suited for lotions, creams, hair care products, and fine fragrances.


Q3: How does dipropylene glycol-LO+ perform as a co-solvent in water-based cleaning formulations?

A: It effectively solubilizes hydrophobic ingredients—including surfactants, fragrances, and active agents—while remaining fully miscible with water and many common organic solvents. Its moderate evaporation rate supports balanced drying times and film formation, making it valuable in hard-surface cleaners, glass cleaners, and disinfectant wipes.


Q4: Can dipropylene glycol-LO+ be used in food-contact applications?

A: While dipropylene glycol-LO+ is not intended for direct food additive use, it may be considered for indirect food-contact applications—such as cleaning agents for food-processing equipment—subject to regulatory review and compliance with applicable local requirements. Formulators should consult relevant food safety authorities and conduct appropriate risk assessments.
