Cetyl acetate is an ester of cetyl alcohol and acetic acid. It is waxy in look and feels and solid in texture. It is water repellent.
It is a 16-carbon molecule, that is not miscible with water, which makes it suitable for a skin-conditioning agent. It also retains moisture within the skin and doesn’t allow to escape. Thus it also acts as emollient. It is used as a masking agent as well. It is used in a variety of products like baby products, cleansing products, eye makeup, hair and skin care products, bath products and shaving products.
Cetyl acetate also known as hexadecyl acetate has a fruity smell and waxy solid appearance. Cetyl acetate is manufactured through esterification of alcohol and acetic acid. Alcohol used in this process in cetyl alcohol which consists of 16 carbon atoms. Cetyl acetate is used as raw materials in manufacturing of cosmetics and personal care products. The basic functions of cetyl acetate in these end-user industries are emollient, masking and skin conditioning agent. Cetyl acetate finds applications in baby products, cleansing products, hair products, eye makeup, skin products and shaving products among others. Cetyl acetate is also used in perfumes and flavors industry. Cetyl acetate also finds application in mechanical industry in lubrication of pins, nuts and bolts in the machines.
The market for cetyl acetate was mainly driven by cosmetics industry. Huge demand from applications such as skin and cleansing products is driving the acetyl acetate market in past few years. Cetyl acetate is used as a moisturizing, skin conditioning, thickening agent in manufacturing of lotions and skin creams. In personal care industry, cetyl acetate is used as opacifier in shampoos. Cetyl acetate helps to keep the hair hydrated and offer softness. Other application such as baby products and makeup industry also exhibits higher demand for cetyl acetate. Due to its fruity smell, cetyl acetate is also preferred in perfumes and aromatics industry. Biomedical applications coupled with growing aromatic industry are likely to be one of the major opportunities for the cetyl acetate market in upcoming years. However, government regulations for regulatory committees FDA, US EPA and REACH are expected to hider the growth of the market in next few years.
Asia Pacific was the leading region in terms of demand for cetyl acetate market in 2013. Asia Pacific is the fastest growing markets for cetyl acetate due to increasing demand for cosmetic and personal care industry in this region. China had the highest demand for cetyl acetate in past few years. Other countries in Asia Pacific region such as Australia, India, South Korea, Taiwan and South Korea are likely to offer bigger markets for cetyl acetate in next few years to come.
However, India is one of the fastest emerging markets for the cetyl acetate and is anticipated to grow in upcoming years. In terms of demand, North America had the second-largest share in cetyl acetate market. Huge demand from cosmetics and personal care products such as shampoos, creams and makeup products has been driving the cetyl acetate market in North America. U.S. had the highest demand for cetyl acetate owing to huge cosmetics industry in this region, However, other countries such as Canada and Mexico are likely to grow in upcoming years owing to increase in demand for personal care products. Regulations from US FDA and US EPA can act as restraint to the market and hinder the growth of the market. Europe was the third-largest market share in the cetyl acetate market in 2013. Italy and France were the highest consumers of cetyl acetate in this region. Germany, the UK, Sweden and Spain are likely to exhibit stable demand for cetyl acetate in next few years. Rest of the World market is anticipated to show positive outlook for the cetyl acetate market in near future. Emerging countries such as Brazil, South Africa are likely to be potential markets for the cetyl acetate in years to come.
Cetyl alcohol, also known as hexadecan-1-ol and palmityl alcohol, is a fatty alcohol with the formula CH3(CH2)15OH. At room temperature, cetyl alcohol takes the form of a waxy white solid or flakes. The name cetyl derives from the whale oil (Latin: cetus) from which it was first isolated.
Preparation
Cetyl alcohol was discovered in 1817 by the French chemist Michel Chevreul when he heated spermaceti, a waxy substance obtained from sperm whale oil, with caustic potash (potassium hydroxide). Flakes of cetyl alcohol were left behind on cooling. Modern production is based around the reduction of palmitic acid, which is obtained from palm oil.
Uses
Cetyl alcohol is used in the cosmetic industry as an opacifier in shampoos, or as an emollient, emulsifier or thickening agent in the manufacture of skin creams and lotions. It is also employed as a lubricant for nuts and bolts, and is the active ingredient in some "liquid pool covers" (forming a surface layer to reduce evaporation and retain heat).
Uses
This medication is used as a moisturizer to treat or prevent dry, rough, scaly, itchy skin and minor skin irritations (e.g., diaper rash, skin burns from radiation therapy). Emollients are substances that soften and moisturize the skin and decrease itching and flaking. Some products (e.g., zinc oxide, white petrolatum) are used mostly to protect the skin against irritation (e.g., from wetness).
Dry skin is caused by a loss of water in the upper layer of the skin. Emollients/moisturizers work by forming an oily layer on the top of the skin that traps water in the skin. Petrolatum, lanolin, mineral oil and dimethicone are common emollients. Humectants, including glycerin, lecithin, and propylene glycol, draw water into the outer layer of skin. Many products also have ingredients that soften the horny substance (keratin) that holds the top layer of skin cells together (e.g., urea, alpha hydroxy acids such as lactic/citric/glycolic acid, and allantoin). This helps the dead skin cells fall off, helps the skin keep in more water, and leaves the skin feeling smoother and softer.
How to use cetyl alcohol topical
Use this product as directed. Some products require priming before use. Follow all directions on the product package. If you are uncertain about any of the information, consult your doctor or pharmacist.
