Toxicity Summary
IDENTIFICATION AND USE: 1-Decanol is a colorless to water-white liquid with a sweet floral or fruity odor. It is used as a chemical intermediate in the production of esters and fragrances and as an artificial flavor in foods. It also finds use in synthetic detergents, lube additives, pharmaceuticals, cosmetics, rubber, and textiles. It is registered for 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: A maximization test was carried out on 25 volunteers using a 3% concentration in petrolatum. No subject became sensitized. ANIMAL STUDIES: There was little evidence of developmental toxicity when 1-decanol was administered, by inhalation, for 7 hours per day (6 hours/day for 1-decanol) on gestation days 1-19 to approximately 15 pregnant rats. 1-Dodecanol was not mutagenic in the Ames test with or without metabolic activation. However, it was rather cytotoxic, and the maximum concentration that could be tested was 50 ug/plate. In another study it was reported to diminish cell mitotic activity and cause structural changes to chromosomes and the mitotic apparatus in Vicia faba after 14 hours exposure. Mice receiving i.p. injections of 1-dodecanol for eight weeks at total doses of up to 12.0 gm/kg showed no statistically significant increase in lung tumor rate relative to controls. ECOTOXICITY STUDIES: The hatching of mosquito eggs was inhibited at a dosage of 5 to 7 liters/hectare by 1-decanol. First, third and fourth instar larvae were killed at a dosage of 3 to 7 liters/hectare. First instar larvae were more sensitive to the alcohols than the older larvae.

Interactions
... The uptake of cholic acid was unaffected by abdominal irradiation, but for glucose, galactose, and four fatty acids the direction and magnitude of the changes in uptake were influenced by the dose of irradiation and by the interval following exposure. The greater uptake of decanol at 6 weeks but lower uptake of decanol at 33 weeks reflected changes in the resistance of the intestinal unstirred water layer.
N-decyl alc induced nutritional encephalomalacia in 1-day-old chicks could be completely prevented by dietary supplementation of dl-alpha-tocopheryl acetate.

Decyl alcohol appears as a clear colorless liquid with a sweet fat-like odor. Flash point 180 °F. Less dense than water and insoluble in water. Vapors are heavier than air.
Decan-1-ol is a fatty alcohol consisting of a hydroxy function at C-1 of an unbranched saturated chain of ten carbon atoms. It has a role as a metabolite, a protic solvent and a pheromone. It is a primary alcohol and a decanol.
1-Decanol has been reported in Alpinia latilabris, Alpinia hainanensis, and other organisms with data available.
decan-1-ol is a metabolite found in or produced by Saccharomyces cerevisiae.

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

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.
