HYDROXYLATED LECITHIN

CAS Number: 8029-76-3 
EC Number: 232-440-6
Molecular Formula: C44H88NO10P


APPLICATIONS


Hydroxylated lecithin has both water-soluble as well as fat-soluble groups in its structure. 
So, hydroxylated lecithin can be used as surfactant. 
Lecithin alone has only lipid solubility but when it is modified as hydroxylated lecithin, it becomes more soluble in water. 
Hydroxylated lecithin can be used as an emulsifier in case of oil in water emulsion. 

When hydroxylated lecithin is applied on skin, hydroxylated lecithin forms a layer on the skin surface which does not let moisture to evaporate. 
Hydroxylated lecithin can condition the skin and make skin moist and soft. 
Hydroxylated lecithin improves the skin’s recovery from different kinds of stressors. 
Hydroxylated lecithin is used in creams and lotions, skincare products.

The food additive hydroxylated lecithin may be safely used as an emulsifier in foods in accordance with the following conditions:
(a) Hydroxylated lecithin is obtained by the treatment of lecithin in one of the following ways, under controlled conditions whereby the separated fatty acid fraction of the resultant product has an acetyl value of 30 to 38:
(1) With hydrogen peroxide, benzoyl peroxide, lactic acid, and sodium hydroxide.
(2) With hydrogen peroxide, acetic acid, and sodium hydroxide.
(b) Hydroxylated lecithin is used or intended for use, in accordance with good manufacturing practice, as an emulsifier in foods, except for those standardized foods that do not provide for such use.
(c) To assure safe use of the additive, the label of the food additive container shall bear, in addition to the other information required by the Act:
(1) The name of the additive, ‘‘hydroxylated lecithin’’.
(2) Adequate directions for its use.

Hydroxylated Lecithin is an emulsifier and clouding agent that is a modified crude lecithin of improved water dispersibility. 
Moreover, hydroxylated Lecithin is manufactured by treating soybean lecithin with peroxide to increase the hydrophilic properties of lecithin. 
Hydroxylated Lecithin is partially soluble in water but hydrates readily to form emulsions. 
Also, hydroxylated Lecithin is used in bakery products because it has an apparent synergy with monoand diglycerides. 
Hydroxylated Lecithin is also used in dry-mixed beverages and margarine. 

It is also termed hydroxylated soybean lecithin.
Hydroxylated Lecithin is Emulsifying agent, which promotes the formation of intimate mixtures between immiscible liquids by modifying the interfacial tension (water and oil).
Hydroxylated Lecithin is Skin care agent, which keeps the skin in good condition.
Hydroxylated Lecithin is Surfactant, which reduces the surface tension of cosmetics and contributes to the uniform distribution of the product during its use.

Lecithin is a natural emulsifying agent and one of the most important components of cells. 
It is a naturally occuring mixture of the diglycerides of stearic, palmitic and oleic acids, linked to the choline ester of phosphoric acid and plays an important role in a cell's metabolism, especially regarding membrane penetration and has been used as a surfactant in cosmetics. 
Lecithin's use in cosmetics was previously limited because of its oxidation and instability against heat, however, Hydroxylated Lecithin (Lecithin with the addition of a hydroxyl -OH group) has all the good qualities of natural lecithin, yet its stability is greatly improved. 
Lecithin improves the homeostatasis of the skin.

Uses and applications of hydroxylated lecithin include: 
-Wetting agent, emulsifier, suspending agent for personal care products and pharmaceuticals; 
-wetting agent and dispersant for air-drying and stoving paints; 
-raw material for textile and leather compds.; 
-emulsifier, clouding agent, defoamer in foods; 
-hairskin conditioner; 
-release agent; 
-in paperpaperboard in contact with aqueousfatty foods; 
-defoamer in food-contact coatings.

Lecithin is a naturally occuring mixture of the diglycerides of stearic, palmitic and oleic acids, while hydrogenated lecithin is produced by adding hydrogen to lecithin. 
Hydroxylated Lecithin is Used in a number of skin products to the appearance of dry or damaged skin.

DEFINITION


Hydroxylated lecithin is chemically modified lecithin. 
Hydroxylated lecithin is made by treating lecithin with hydrogen peroxide and an organic acid such as acetic or lactic acid. 
In the process of producing hydroxylated lecithin, some of the organic acid becomes peroxy acid. 
The peroxy acid reacts with olefins in the fatty acid side chains creating intermediate epoxides. 

The epoxides react further with water, organic acid, or peroxy acid, to ultimately form vicinal diols. 
Because the natural fatty acid olefins have (Z)-configurations, the resulting vicinal diols have anti stereochemical configurations.
Fatty acids with hydroxyl groups on their hydrophobic tails are rare in nature. 
Compare hydroxylated lecithin to castor oil, which has 3 hydroxylated fatty acid chains in it. 
Hydroxyl groups give these oils unique polar properties that make them useful in a variety of applications, including cosmetics, pharmaceuticals, and foods.

Hydroxylated lecithin is lecithin reacted with organic acids such as lactic acid and hydrogen peroxide. 
Hydroxylated lecithin is a natural emulsifier found in cells in our body. 
Hydroxylated lecithin can be considered a natural mixture of stearic, palmitic and oleic acid connected with choline ester of phosphoric acid. 
Hydroxylation makes the lecithin emulsifier that works in water as well. 
Also, hydroxylated lecithin provides stability against oxidation and heat.

Hydroxylated lecithin is derived from a complex mixture of acetone-insoluble phosphatides from soybean and other plant lecithins, consisting chiefly of phosphatidyl choline, phosphatidyl ethanolamine, and phosphatidyl inositol, as well as other minor phospholidpids and glycolipids mixed with varying amount of triglycerides, fatty acids, sterols, and carbohydrates. 
The mixture is treated with hydrogen peroxide, benzoyl peroxide, lactic acid, and sodium hydroxide, or with hydrogen peroxide, acetic acid, and sodium hydroxide, to produce a hydroxylated product having an iodine value approximately 10% lower than that of the starting material. 
Hydroxylated lecithin may vary in consistency from fluid to plastic, depending upon the content of free fatty acid and oil and whether it contains diluents. 

Hydroxylated lecithin is light yellow in color and has a characteristic "bleached" odor. 
Hydroxylated lecithin is partially soluble in water, but hydrates readily to form emulsions; hydroxylated lecithin is more dispersible and hydrates more readily than crude lecithin.
Hydroxylated lecithin appears to increase gluten extensibility and water dispersibility. 
No detailed metabolic studies on this substance are available, which itself is not a normal constituent of the body, although lecithin itself is an essential constituent of all cells of the human body.

Hydroxylated lecithin is a substance used in cosmetic formulations. 
The substance acts as emulsifier (changes the interfacial tension of liquids like water and oil so that they can be mixed together), skin care product and surfactant (washing-active substance).
Lecithin is a group of substances belonging to the phosphatides (phospholipids) in which phosphoric acid, fatty acids, an alcohol and a nitrogen-containing component (choline or colamine = 2-aminoethanol) are linked together. 

The linkages (esterifications) result in a multitude of possible substances.
Hydroxylated lecithin is chemically modified lecithin. 
Hydroxylated lecithin is solvable in water. 
Hydroxylated lecithin is Mainly used in Food, Agro chemical industries.
