About this ingredient

Dipropylene Glycol (DPG) is a synthetic glycol with two propylene glycol units. A clear viscous liquid with a slightly sweet taste and low odor. Produced by dimerization of propylene glycol. Mechanism. Universal solvent. Dissolves fragrances, essential oils, active ingredients, UV filters. A humectant with a mild moisture-retention effect in the stratum corneum. Reduces formula viscosity, improves distribution and absorption. Compared with propylene glycol – less skin irritation and less frequent contact dermatitis. Where applied. Perfumery (as solvent), color cosmetics (mascara, shadows, foundations), serums and creams with active ingredients, antiperspirant deodorants, hair products. In Spain – mass-market decorative lines L'Oréal, Maybelline, Bourjois, Mercadona Sublime perfumery. Evidence base. A functional component with many years of use. Solvent and humectant efficacy confirmed. No active skin pharmacology. Safety. CIR in 2012 confirmed Dipropylene Glycol safety in cosmetic use at concentrations up to 30%. The EU permits it in cosmetics without concentration restrictions. Contact allergies are rare, noticeably less common than with propylene glycol. Pregnancy and lactation – safe at standard cosmetic concentrations. Best suited to: any skin type. A good choice for patients who don't tolerate propylene glycol – DPG is usually better tolerated.
