While Benzophenone-type filters have a good absorbance in the UV-B region, they do not block UV-A radiation efficiently. Therefore, a series of Benzotriazole filters for use in personal care products exhibit strong performance over the whole ultraviolet range.
Organic compounds
C10-30 Cholesterol/Lanosterol Esters is a highly diverse ester complex derived from wool wax, combining branched-chain fatty acids, cholesterol, and related sterols. It is a snow-white, odorless, and amorphous soft solid with a pleasant, non-greasy, emollient feel and melting point of 30-38°C.
Balancing the dimeric surfactant with lactylate in Ceralution™ F leads to an additive that is milder and more efficient than betaines in lowering the irritation potential of standard ether sulfates.
Cetyl Acetate is an active, hydrophobic, clear liquid ester. It has the property of sometimes crystallizing at ambient temperatures. It is a liquid or a soft solid at 25ºC. At reduced temperatures, it will haze or solidify. Warm to 40-50°C to restore clarity and/or liquid state.
Diacetyl Boldine (DAB) is a derivative of Boldine, an alkaloid initially found in the Boldo (Peumus boldus). It is also known under the Sederma's trade name Lumiskin™.
Dihydroabietyl Behenate is a completely vegetable-derived ester formed by the reaction of Dihydroabietyl Alcohol with Behenic Acid. It is semi-solid at ambient temperatures, oil-soluble, and water-insoluble.
Dilinoleamidopropyl Dimethylamine is a reaction product of dilinoleic acid and dimethylaminopropyl-dimethylamine, is molecularly more than half vegetable derived with the remainder synthetic.
Glycereth-7 Benzoate is a colorless to slightly yellow viscous liquid. It is dispersible with water and castor oil and exhibits self-emulsifying properties, enabling dense formulations that tend to deposit on the skin.
Isocetyl Behenate is a low-viscosity, stable, vegetable-derived liquid ester. It is a clear yellow liquid at 25°C without odor and taste. It is miscible with natural and mineral oils and silicones; and insoluble in water, ethanol, and propylene glycol.
Isododecane is a synthetic aliphatic hydrocarbon with a branched structure. It is a safe, non-irritating, and non-comedogenic cosmetic-grade solvent and emollient with low viscosity, good volatility, spreadability, and drying time.
Isoeicosane is a clear, color- and odorless liquid hydrocarbon with low viscosity and good spreadability. It is used as a conditioner in hair care and as a lipophilic, low-viscosity carrier in skin and sun care.
Isohexadecane is a clear, colorless, and odorless liquid with a slight volatility. It is used in skin and sun care products to leave a silky, light-emollient feeling on the skin. It is dermatologically safe, non-comedogenic, and non-greasy.
Isooctane is a colorless liquid with low odor intensity. It is volatile and evaporates rapidly.
Isostearyl Palmitate is a clear, practically odor-free liquid ester derived from all vegetables. It is soluble in mineral and natural oils and insoluble in water, ethanol, and propylene glycol. It has excellent esthetic properties and produces non-greasy, tack-free films.
Kinetin is a cytokinin, a plant growth factor. It is a compound found in nature, including plants, animals, and human DNA.
Octyldodecyl Erucate is an oil-soluble, liquid ester. It is wholly vegetable-derived. A long carbon chain length ester (42 carbon atoms) is surprisingly shallow in viscosity and has excellent shelf-life and clarity at low temperatures.
Oleth-3 is an ethoxylated oleyl alcohol with three moles of ethylene oxide. It is an off-white, hazy liquid with a mild, characteristic odor (virtually odorless).
Oleth-5 is an ethoxylated oleyl alcohol with five moles of ethylene oxide, an off-white, hazy liquid with a mild, characteristic odor (virtually odorless).
Oleyl Lactate is a vegetable-derived, slightly yellow, clear to slightly hazy, somewhat viscous liquid at ambient temperatures with a slightly fatty odor. It is miscible with natural and mineral oils, dispersible with propylene glycol, and insoluble in water and ethanol.
Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate is a structurally modified BHT. This highly efficient phenolic antioxidant does not exhibit the drawbacks associated with BHT (high volatility and photo-oxidative yellowing) and is helpful for product protection and stabilization.
Sodium Coco-Sulfate (CFAS) is a naturally derived anionic surfactant produced by sulfating coconut-derived fatty alcohols. As more people become familiar with its unique properties, it is beginning to be used in personal care applications.
Tetrahydrofurfuryl Methacrylate is a tetrahydrofurfuryl ester of methacrylic acid obtained by transesterification of tetrahydrofurfuryl alcohol and methyl methacrylate.
Triclocarban (TCC) is an antimicrobial agent with wide activity against Gram-positive bacteria. It is particularly suitable for application in deodorant soaps and other products such as sticks, roll-ons, creams, and lotions when antibacterial activity is required.
Chelating agents are often combined with phenolic AOs to complex heavy metal ions, resulting in synergistic antioxidant mixtures that impart stabilizing properties to products.
