What is levulinic acid used for?

What is levulinic acid used for?

Levulinic acid and its derivatives, like sodium levulinate, are used in organic and natural cosmetic compositions for perfuming, skin conditioning and pH-regulating purposes. They give inherent fresh odor, prevent wrinkles and stabilize formulations and emulsions.

What is levulinic acid in skin care?

Levulinic acid is a corn extract that prevents microbial build-up in cosmetics and skin care. The ingredient is bio-based, water soluble and quite clear in the tone.

What is levulinic acid derived from?

Levulinic acid, or 4-oxopentanoic acid, is an organic compound with the formula CH3C(O)CH2CH2CO2H. It is classified as a keto acid. This white crystalline solid is soluble in water and polar organic solvents. It is derived from degradation of cellulose and is a potential precursor to biofuels, such as ethyl levulinate.

Is levulinic acid a ketone?

Levulinic acid is a five-carbon molecule with carboxylic acid and ketone functionalities, and the existence of these two functional groups provides this compound with interesting reactivity pathways.

Is levulinic acid safe?

However, for the most part, products containing levulinic acid are perfectly safe for your use. Not only is the product believed to be non-carcinogenic, but it’s also not suspected to be an environmental toxin, can be used in food, and is not believed to accumulate in harmful levels in your body.

What acid is green?

Nitric acid and copper makes a green remarkably similar to cartoon colors.

Is citric acid in skincare?

In skincare formulations, Citric Acid has protective antioxidant, and corrective antiaging effects helping to reverse visible signs of photodamage. Citric Acid works by exfoliating the upper layer of dead skin cells to help clean pores, even skin tone and soften and smooth the skin.

Is levulinic acid natural?

Levulinic acid is a renewable, bio-based acid, usually from corn, which helps to condition and soften skin, as well as act as a preservative of the product itself.

How is levulinic acid produced?

The formation of levulinic acid from carbohydrates consists of a series of consecutive reactions which includes a hexose triple dehydration step to produce 5-hydroxymethylfurfural (HMF) and the rehydration of HMF with two molecules of water to produce levulinic acid and formic acid.

Why is dimethicone bad?

Some people believe that dimethicone is harmful because it’s not natural. Others say that since it forms a barrier, dimethicone seals in oil, sweat, dirt, and other things that can clog pores and lead to acne. However, the amount of dimethicone in face and hair products is generally considered safe.

Is potassium sorbate toxic?

Potassium Sorbate: A preservative used to suppress formation of molds and yeasts in foods, wines and personal care products. In-vitro studies suggest that it is toxic to DNA and has a negative affect on immunity.

What Colour is acid rain?

When you add acid, bromothymol blue turns yellow; when you add a base (like sodium sulfite), it turns blue. Green means neutral (like water).

How is levulinic acid converted to liquid fuel?

Levulinic acid can be upgraded to other platform molecules, including GVL. In fact, in 2010, Dumesic and his group developed a highly efficient two-step catalytic process for converting levulinic acid to GVL, and ultimately, into high-energy liquid transportation fuel.

What kind of solvent does James Dumesic use?

In addition to their work involving the synthesis of new solvents from lignin, Dumesic and his group have recently developed new catalytic processing strategies using GVL as a biomass-derived solvent.

What kind of research does James Dumesic do?

Throughout his career, Dumesic has used spectroscopic, microcalorimetric, and reaction kinetics techniques to study the surface and dynamic properties of heterogeneous catalysts.

What is the field of microkinetic analysis Dumesic?

Dumesic pioneered the field of microkinetic analysis, in which diverse information from experimental and theoretical studies is combined to elucidate the essential surface chemistry that controls catalyst performance.
