Biological Activity
| ADME/Pharmacokinetics |
Absorption, Distribution and Excretion An in vitro percutaneous absorption study of 3-phenyl-1-propanol, across human skin was conducted using a diffusion cell. Skin samples, approximately 280 um thick, were obtained from cosmetic surgical human abdominal skin. The dermatomed skin samples were fixed in 4% formaldehyde, embedded in paraffin. 3-Phenyl-1-propanol (5.0 mg/mL, working concentration) was dissolved in buffer solution at a concentration equivalent to approximately 75% of its solubility in that medium. The solution was used to fill the donor compartment while the receptor compartment was filled with pH 7.4 buffer solution. The experiments were carried out at 37 °C. The cells were immersed in a thermostatically regulated water bath. Assay duration was 7 hr. Receptor compartment sampling was carried out every 30 min and the extracted samples were replaced with the buffer solution. Samples were analyzed by gas chromatograph with a flame ionization detector. The mean permeability coefficient for 3-phenyl-1-propanol was reported to be 52.35 +/- 4.98 Kp[cm/hour] and the flow value was 1.18 +/- 0.11 J[mg/hr]. |
| Toxicity/Toxicokinetics |
Toxicity Summary IDENTIFICATION AND USE: 3-Phenylpropanol is a colorless liquid. It smells like hyacinths and tastes similar to apricot. It occurs in many fruits and berries, cinnamon and some types of balsam. 3-Phenylpropanol occurs in tobacco smoke. 3-Phenylpropanol is typically used as a perfume for applications such as antiperspirants, creams-lotions, lipsticks, talcum powder, tablet soap, shampoo, hair conditioner, bath/shower gel, detergent powder, liquid detergent, fabric softener, candles, incense. Also used in blossom compositions for balsamic and oriental notes. It is not registered for current pesticide use in the U.S., but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses. HUMAN EXPOSURE AND TOXICITY: In a multicenter study, 218 fragrance sensitive patients with proven contact dermatitis were patch tested. Reactions (0.9%) in fragrance sensitive patients were observed with 3-phenylpropanol at 5% in petrolatum. ANIMAL STUDIES: In rats dosed orally with 3-phenylpropanol at dose levels of 1.31, 2.56 and 5.0 g/kg/bw deaths occurred within the first 2 days. The clinical signs observed were slight lethargy and flaccid muscle tone. In a preliminary screen for an acute oral toxicity study, a 50% solution of 3-phenyl-1-propanol in corn oil was administered orally to 10 rats at a dose level of 5 g/kg bw, nine (9/10) rats died. In another study, rats were dosed orally with a 50% solution of 3-phenylpropanol in corn oil at dose levels of 1.47, 2.15, 3.16 and 4.64 g/ kg bw. One death occurred at 1.47 g/kg; and at 2.15 and at 4.64 g/kg. The clinical signs observed during the study were depression, hypopnea, ataxia and piloerection. Gross observations at necropsy revealed dark red areas in the lungs at the three lower doses and dark red lungs at the highest dose. In an irritation study in rabbits 3-phenylpropanol was applied for 24 hr under occlusion at dose levels of 2.5 and 5 g/kg. At 2.5 g/kg, moderate erythema and slight to moderate edema were observed. At 5 g/kg, moderate to severe erythema and moderate edema were observed. In another study in rabbits, 3-phenyl-1-propanol was applied for 24 hr under occlusion at 5 g/kg. Moderate to severe erythema, severe edema, scaling and necrosis were observed. A 0.5 mL aliquot of 3-phenylpropanol was applied to intact and abraded skin for 24 hr under occlusion. Moderate irritation was observed. Necrosis was also observed. No mutagenic or genotoxic activity in bacteria and mammalian cell line assay was found.

Solubility Data
| Solubility (In Vitro) | May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples |
| Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples. Injection Formulations (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution.
