stearyl alcohol

CAS No. 112-92-5

Formula: C18H38O
Basic Info

Stearyl alcohol (also known as octadecyl alcohol or 1-octadecanol) is an organic compound with the formula CH3(CH2)16CH2OH. It is classified as a fatty alcohol. It takes the form of white granules or flakes, which are insoluble in water. It has a wide range of uses as an ingredient in lubricants, resins, perfumes and cosmetics. It is used as an emollient, emulsifier, and thickener in ointments of various sorts, and is widely used as a hair coating in shampoos and hair conditioners. It has also found application as an evaporation suppressing monolayer when applied to the surface of water.
Stearyl alcohol is prepared from stearic acid or some fats by the process of catalytic hydrogenation. It has low toxicity.

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: no data available
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Using the Warburg test which employs activated sludge, 1-octadecanol gave a theoretical oxygen demand of 0.3, 0.5, and 0.3 percent in 6, 12, and 24 hours(1). However, using an acclimated mixed shake flask culture with incremental substrate addition of 1-octadecanol, biomass yield reached 54.5 percent after seven days(2). Given sufficient time in contact with adapted microbial species under conditions otherwise non-limiting, the complete disappearance of 1-octadecanol as identifiable molecular species will occur(2).

12.3 Bioaccumulative potential

An estimated BCF value of 2.8X10+4 was calculated for 1-octadecanol(SRC), using an experimental water solubility of 1.1X10-3 mg/L at 25°C(1) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is very high(SRC), provided the compound is not metabolized by the organism(SRC).

12.4 Mobility in soil

The Koc of 1-octadecanol is estimated as 1.8X10+5(SRC), using a water solubility of 1.1X10-3 mg/L at 25°C(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1-octadecanol is immobile in soil(SRC).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
