What is the pH of Lauramine oxide?

What is the pH of Lauramine oxide?

At pH 7 and above, both Lauramine Oxide and Steararnine Oxide are essentially nonionic, but below pH 3, they are primarily cationic (Devinsky, 1985; Swern, 1979; Weinstein, 1979). Lauramine Oxide and Stearamine Oxide are typically manufactured by slowly mixing each amine with 35% hydrogen peroxide at 60°C.

What happens when you oxidize an amine?

Oxidation. Although you can oxidize all amines, only tertiary amines give easily isolated products. The oxidation of a tertiary amine leads to the formation of an amine oxide. Arylamines tend to be easily oxidized, with oxidation occurring on the amine group as well as in the ring.

What does C10 16 Alkyldimethylamine oxide do?

Alkyl dimethyl amine oxide (chain lengths C10–C16) is the most commercially used amine oxide. In North America, more than 95% of amine oxides are used in home cleaning products. They serve as stabilizers, thickeners, emollients, emulsifiers, and conditioners with active concentrations in the range of 0.1–10%.

What is Decamine oxide?

A low foaming surfactant compatible with most common surfactant systems with no thickening effect, and proves stable in: acid and alkaline conditions.

Is lauramine oxide ionic?

Non-ionic / cationic surfactant (pH dependant) used as emulsifier and foam booster in liquid hand dishwashing formulations.

What type of surfactant is lauramine oxide?

amine oxide
Lauramine Oxide is a surfactant known as an amine oxide. It is widely used in a widely industrial applications where coupling, detergency and compatibility are important. High foaming surfactant, emulsifier, detergent, foam enhancer, foam stabilizer.

Is amine acidic or basic?

Amine are basic and easily react with the hydrogen of acids which are electron poor as seen below. Amines are one of the only neutral functional groups which are considered basis which is a consequence of the presence of the lone pair electrons on the nitrogen.

Why do amines turn yellow?

Tertiary amines are prone to turning yellow or brown during their storage. This is usually attributable to unknown impurities which form over time.

Is Alkyldimethylamine oxide toxic?

The European Union Ecolabel program reports this substance is anaerobically degradable. The international Organisation for Economoic Co-operation and Development reported that amine oxides are not genotoxic. Organisation for Economic Co-Operation and Development.

How do you make amine oxide?

Amine oxides are prepared by oxidation of tertiary amines or pyridine analogs with hydrogen peroxide (H2O2), Caro’s acid or peracids like mCPBA in N-oxidation.

What is Decylamine oxide?

Decylamine oxide is a cleaning agent, or “surfactant,” that can also be found in shampoos and gel dishwashing detergents. It is particularly good at removing soap scum.

What elements are in amine oxide?

Lesson Summary Amine oxide is an organic compound (carbon-hydrogen based) which has the formula R3 N+-O-. An amine oxide has three ‘R’ groups and an oxygen bonded to a central nitrogen atom.

What is the PK a of H2O in pKa?

pKa Values of Common Bases Values in H 2O as much as possible, so common comparisons (i.e., H 2OpK a = 15.7) can still be used Note; The pK a values associated with bases is normally meant to refer to the true pK a’s of their conjugate acids; i.e., pK a associated with HO-is 15.7, which is the pK a of H 2O. This is often sloppily used by

What are the properties of alkyl amine oxides?

Long-chain alkyl amine oxides are used as amphoteric surfactants and foam stabilizers. Amine oxides are highly polar molecules and have a polarity close to that of quaternary ammonium salts. Small amine oxides are very hydrophilic and have an excellent water solubility and a very poor solubility in most organic solvents.

Are Amine oxides soluble in organic solvents?

Small amine oxides are very hydrophilic and have an excellent water solubility and a very poor solubility in most organic solvents . Amine oxides are weak bases with a pKb of around 4.5 that form R 3 N + −OH, cationic hydroxylamines, upon protonation at a pH below their p Kb .

What is the best oxidising agent for amine oxides?

Almost all amine oxides are prepared by the oxidation of either tertiary aliphatic amines or aromatic N-heterocycles. Hydrogen peroxide is the most common reagent both industrially and in academia, however peracids are also important. More specialised oxidising agents can see niche use, for instance Caro’s acid or m CPBA.
