리놀레인산 MSDS


cis-9,cis-12-Octadecadienoic acid

리놀레인산 C화학적 특성, 용도, 생산

물성

옅은 노란색 레드 유성 액체.

화학적 성질

Liquid at room temperature, colorless

화학적 성질

Linoleic acid occurs as a colorless to light-yellow-colored oil.

용도

linoleic acid (vitamin F) is also known as omega-6. An emulsifier, it is also cleansing, emollient, and skin conditioning. Some formulations incorporate it as a surfactant. Linoleic acid prevents dryness and roughness. A deficiency of linoleic acid in the skin is associated with symptoms similar to those characterizing eczema, psoriasis, and a generally poor skin condition. In numerous laboratory studies where a linoleic acid deficiency was induced, a topical application of linoleic acid in its free or esterified form quickly reversed this condition. In addition, there is some evidence in laboratory tests that linoleic acid may inhibit melanin production by decreasing tyrosinase activity and suppressing melanin polymer formation within melanosomes. Linoleic acid is an essential fatty acid found in a variety of plant oils, including soybean and sunflower.

정의

ChEBI: An octadecadienoic acid in which the two double bonds are at positions 9 and 12 and have Z (cis) stereochemistry.

생산 방법

Linoleic acid is obtained by extraction from various vegetable oils such as safflower oil.

정의

An unsaturated carboxylic acid that occurs in LINSEED OIL and other plant oils. It is used in making paints and varnishes.

정의

linoleic acid: A liquid polyunsaturatedfatty acid with two doublebonds, CH3(CH2)4CH:CHCH2-CH:CH(CH2)7COOH.Linoleic acid isabundant in plant fats and oils,e.g.linseed oil, groundnut oil,and soyabeanoil.It is an essential fatty acid.

일반 설명

Colorless to straw colored liquid. A polyunsaturated fatty acid essential to human diet.

공기와 물의 반응

Sensitive to air and light. . Oxidizes across carbon double bonds

반응 프로필

Linoleic acid reacts to neutralize bases. May react vigorously with oxidizing agents. May react exothermically with reducing agents to release hydrogen gas.

화재위험

Flash point data for Linoleic acid are not available. Linoleic acid is probably combustible.

Pharmaceutical Applications

Linoleic acid is used in topical transdermal formulations, in oral formulations as an absorption enhancer, and in topical cosmetic formulations as an emulsifying agent, and in aqueous microemulsions.It is also used in parenteral emulsions for total parenteral nutrition and in nonprescription oral dietary supplements.

Safety

Linoleic acid is widely used in cosmetics and topical pharmaceutical formulations, and is generally regarded as a nontoxic material. On exposure to the eyes, skin, and mucous membranes, linoleic acid can cause mild irritation.

저장

Linoleic acid is sensitive to air, light, moisture, and heat. It should be stored in a tightly sealed container under an inert atmosphere and refrigerated.

비 호환성

Linoleic acid is incompatible with bases, strong oxidizing agents, and reducing agents.

Regulatory Status

GRAS listed. Approved for use in foods in Europe and the USA.
