Chemical-navi - Nikkol
Odor: characteristic
Use: Dibasic acid ester; good solubility and penetration; light feel; penetrating agent for topical drug forms.
Crodamol™ DA
Odor: bland
Use: Exceptionally low viscosity emollient. Plasticiser for nail varnish, hair spray and other styling aids. Solvent for lipophilic actives, dyestuff and chemical sunscreens. Excellent water/alcohol solubility.
Odor: characteristic
Use: HallStar DIPA is a multifunctional, (solvent for aromatic oils, coupler, emollient, lubricant, plasticizer) synthetically produced diester of Isopropyl Alcohol and Adipic Acid. It is non-occlusive, non-oily, light emollient with excellent spreading properties. Used in bath oils, it delivers a soft feel to skin. In sunscreens, it solubilizes solid organic UV filters and its relatively high polarilty may assist with Avobenzone photostabilization. Recommended use level: 0.1%-25%, depending upon application (lower end as a plasticizer, higher as an emollient. sunscreen solvent or hydro-alcoholic coupler, high end as a bath oil additive).
Inoue Perfumery
Lubrizol Corporation
Schercemol™ DIA Ester
Odor: charateristic
Use: Schercemol DIA ester is often used in hydroalcoholic formulations because of its excellent compatibility in such systems. Typical end uses for Schercemol DIA ester in hydroalcohol products are pre-electric and after shave lotions, where it functions as a non-oily emollient. Dry oil sprays are another popular application, where Schercemol DIA ester is valued for its rapid absorbency and low residual tack. Other usages include sun care, deodorants, lipsticks, hand lotions and men's grooming aids.
