Vaporizers used for delivery of pharmaceuticals or personal-care products often include propylene glycol among the ingredients. [7] In alcohol-based hand sanitizers, it is used as a humectant to prevent the skin from drying. [19] Propylene glycol is used as a solvent in many pharmaceuticals, including oral, injectable, and topical formulations.

This hydrating property can also be needed to counteract a dehydrating active ingredient (e.g., soaps, corticoids, and some alcohols), which is why humectants are common ingredients in a wide range of cosmetic and personal care products that make moisturization claims (e.g., hair conditioners, body lotions, face or body cleansers, lip balms ...
When hexylene glycol binds to these different locations, water is removed and the protein crystals anneal, which prevents ice formation during cryocrystallography techniques. [16] Incorporation of hexylene glycol into solution has been known to improve the resolution of X-ray diffraction making protein structures easily identifiable. [ 17 ]
INCI names often differ greatly from systematic chemical nomenclature or from more common trivial names and is a mixture of conventional scientific names, Latin and English words. INCI nomenclature conventions "are continually reviewed and modified when necessary to reflect changes in the industry, technology, and new ingredient developments". [2]
IPBC was approved in 1996 for use up to 0.1% concentrations in topical products and cosmetics. However, this preservative is mostly found in cosmetics at about one-eighth that level [Maier et al., 2009]. IPBC Toxicity and Safety Tests show it to be generally safe: When used properly in leave-on skin products, IPBC is extremely safe [Steinberg ...
Dipropylene glycol finds many uses as a plasticizer, an intermediate in industrial chemical reactions, as a polymerization initiator or monomer, and as a solvent.Its low toxicity and solvent properties make it an ideal additive for perfumes and skin and hair care products.
It is easily soluble in water and alcohol, moderately soluble in diethyl ether, soluble in chloroform (1:100), [7] in propylene glycol, and slightly soluble in glycerin. Panthenol's expanded chemical formula is HO–CH 2 –C(CH 3) 2 –CH(OH)–CONH–CH 2 CH 2 CH 2 –OH.
