Structurally similar to stearic acid, 12-Hydroxy Stearic Acid is entirely vegetable-based and derived from naturally-occurring fats and oils, most commonly castor oil. 
12-Hydroxy Stearic Acid is synthesized by oxidizing 2-hexylcyclododecanone with a mixture of permaleic and peracetic acids in methylene chloride. 
This forms the lactone of 12-Hydroxy Stearic Acid, and alkaline hydrolysis of the lactone produces 12-Hydroxy Stearic Acid.

Sold in solid flakes, 12-Hydroxy Stearic Acid has a typical shelf life of up to two years past date of manufacture — the exact shelf life will vary based on storage conditions. 
To get the longest life out of 12-Hydroxy Stearic Acid, store the chemical according to material safety data sheet (MSDS) recommendations.

12-Hydroxy Stearic Acid: An Oleochemical Solution
While many traditional chemicals are classified as petrochemicals, 12-Hydroxy Stearic Acid is categorized as an oleochemical.

12-Hydroxy Stearic Acids are produced from petroleum oil-based products, and they are not known for their environmentally-friendly effects — many critics condemn petrochemicals for damaging the air, soil and water. 
12-Hydroxy Stearic Acid also tend to absorb easily into the skin, potentially creating issues in human health.

Alternately, oleochemicals are chemicals derived from natural sources, most commonly plant and animal fats. 
Because they are typically pollution-free, biodegradable and have very low toxicity, oleochemicals are an attractive alternative to traditional petrochemical compounds. 
Consumers are increasingly concerned about the ingredients of their cosmetic products — if something comes into contact with their skin, they want 12-Hydroxy Stearic Acid to be natural and healthy.

Nonflammable, non-reactive and not an explosive hazard, 12-Hydroxy Stearic Acid isn’t irritating to skin and doesn’t lead to respiratory distress. 
This makes 12-Hydroxy Stearic Acid an especially attractive alternative to petroleum-based thickeners, emollients and surfactants on the market.

The most popular use for 12-Hydroxy Stearic Acid is in the cosmetics and personal care industry. 
Because 12-hydroxy stearic acid is effective in a range of functions, 12-Hydroxy Stearic Acid is a versatile and popular ingredient for many different products.

Some of the most popular applications for 12-Hydroxy Stearic Acid include the following products:
Lotions
Creams
Gels
Make-up and decorative cosmetics
Hair care, such as shampoos, conditioners and styling products

Skin care, such as facial care and cleansing, body care and baby care products
SPF enhancement
Sun care, such as sun protection, self-tanning and after-tanning products
Underarm deodorants
In any given cosmetics product, 12-Hydroxy Stearic Acid is used in three primary functions — as a surfactant, emollient and thickener.

12-Hydroxy Stearic Acid, also known as 12-hydroxy-octadecanoate or DL-12-hydroxy stearate, belongs to the class of organic compounds known as long-chain fatty acids.

Salts made from 12-HSA can function as oil/water emulsifiers. 
12-Hydroxy Stearic Acid can be used as an emollient in underarm deodorant sticks, gel lipsticks, hair styling products, creams and lotions.

12-Hydroxy Stearic Acid is a castor oil derivative used in a variety of cosmetic applications. 
It is often used by formulators as an emollient in skin care products and is also a common surfactant in soaps. 
12-Hydroxy Stearic Acid is used predominately in antiperspirants and deodorants, lip gels, hair styling waxes, and skin creams and lotions

2-Hydroxy stearic acid is a saturated hydroxy fatty acid.
12-Hydroxy Stearic Acid is a waxy, odourless, tasteless and cream coloured compound in flakes / powder.
12-Hydroxy Stearic Acid is used as a surfactant-cleansing agent in cosmetic products.

12-Hydroxy Stearic Acid has been used as a textile lubricant and as a saponifiable base for greases. 
12-Hydroxy Stearic Acid-polyethylene glycol block polymers have been approved by FDA for use as surfactants, for dispersions of polyacrylamide retention and draining aids, employed prior to the sheet forming operation in the manufacture of paper and paperboard that come in contact with aqueous and fatty foods.
Lithium greases; chemical intermediates

Methods of Manufacturing of 12-Hydroxy Stearic Acid
12-Hydroxy Stearic Acid may be synthesized as follows: 2-hexylcyclododecanone is oxidized with a mixture of peracetic and permaleic acids in methylene chloride to form the lactone of 12-Hydroxy Stearic Acid. 
Alkaline hydrolysis of the lactone leads to the production of 12-Hydroxy Stearic Acid. 
Acylcyclododecanones, such as 2-hexylcyclododecanone, can be obtained by the addition of cyclododecanone at the double bond of the respective 1-alkene. 
This reaction occurs through a radical-chain mechanism; organic peroxides are used as initiators. 
The catalytic hydrogenation of castor oil to 12-Hydroxy Stearic Acid has also been reported.

The synthesis of four sugar-based surfactants derived from glucose and (R)-12-Hydroxy Stearic Acid is described. 
The surfactants have a hydroxy group in the hydrophobic part, which is either free or acylated using acetyl chloride, hexanoyl chloride, or myristoyl chloride. 
Three of the synthesized surfactants are water-soluble and are evaluated with respect to their critical micelle concentrations and hemolytic activities.

The fourth surfactant has limited water solubility and is not further included in the study. 
The investigated surfactants are all hemolytic close to their respective critical micelle concentration indicating that their use in parenteral formulations may be limited. 
Nevertheless, surfactants having the proposed structure appear as promising alternatives to existing solubilizing agents for pharmaceutical applications.
