Lactic Acid Liquid, Food Additive Material, Improve The Taste,
80%-88% Concentration, Colorless Or Light Yellow
Lactic Acid is an organic acid with chemical formula C3H6O3. It is also known as milk acid. When milk sugar (lactose)
undergoes fermentation, the product obtained is lactic acid. It is
found in cottage cheese, leban, sour milk, yogurt, and Koumiss.
Levo and Dextro are two forms of optical isomers of lactic acid. In
the year 1780, Carl Wilhelm Scheele a Swedish chemist isolated
lactic acid from sour milk for the first time. This compound is
water-soluble and white in its solid state whereas it is colourless
in its liquid state. The soluble salt of lactic acid like calcium
lactate can be used as a source of calcium. The PH of 1 mM of
lactic acid is about 3.51.

1. Electroless nickel plating complexing agent
Lactic acid has a unique complexation constant for nickel. More
than 97% of the nickel ions in the electroless nickel plating
solution of the lactic acid-nickel ion system are in the complex
ion state, and the free nickel ion content is less than 3%.
Therefore, lactic acid is commonly used for electroless nickel
plating. One of the complexing agents. Compared with other
complexing agents, lactic acid has strong stability in the plating
solution, which can effectively control the deposition rate to
ensure uniform and fine plating and stable plating solution. In
addition, it is also very effective for suppressing the
precipitation of nickel phosphite generated during the electroless
nickel plating operation. Lactic acid has excellent synergistic
ability, and can form binary or multi-component complexing agent
with various complexing agents such as sodium citrate, malic acid
and succinic acid, further satisfying the demand for complexing
agent in the electroless nickel plating industry.
2. Paint and coating industry
Lactic acid is used as a pH adjuster and a synthetic agent in
various water-based coating bonding systems. Such as: coating of
electrodeposited materials. Methyl lactate and butyl lactate are
synthetic agents for paints, coatings and resins, and butyl lactate
is widely used as a brightener for painting and baking varnishes
for automotive home appliances.
Lactic acid can maintain the humidity of tobacco, remove impurities
in tobacco, change taste, neutralize nicotine nicotine, reduce
harmful components and improve tobacco quality. Lactic acid can be
used to synthesize L-lactate lactate, used as a flavoring agent for
tobacco flavor. It has the function of shielding bitter and
astringent taste, leaving a fresh sense of smoking in the mouth;
potassium lactate is a commonly used coke-burning improver;
magnesium lactate and calcium lactate can also be used as tobacco
additives to improve gray gray matter.
4. Cleaning agent
Lactic acid ester is an excellent and safe high-boiling solvent
with excellent solubility and unique solubility for grease and
polymer soils, and has the best environmental and toxicological
properties. A formulation that can be used alone or in addition to
a cleaning solvent for degreasing and cleaning of a variety of
precision machinery and cleaning prior to surface coating.
5. Tanning and textile industry
In the tanning industry, lactic acid removes the lime and calcium
from the leather, making the leather soft and fine, resulting in
high-grade leather. In the textile industry, lactic acid is used to
treat fibers, making it easy to color, increasing gloss and making
the touch soft.
6. Alcohol industry
Ethyl lactate is a colorless volatile liquid with special rum,
fruit and creamy aromas. It is widely used as a flavoring agent for
white wine and fruit wine.
