Description
Cetyl Esters Wax, also known as Cetyl Palmitate, is a white to off-white, somewhat translucent flake with a crystalline structure and a pearly luster when caked. It has a faint, aromatic odor and a bland, mild taste. It is derived from the esterification of cetyl alcohol and fatty acids, making it a versatile ingredient in various industries.
Uses
Used in Cosmetics and Personal Care Industry:
Cetyl Esters Wax is used as an emollient and emulsifying agent for its ability to provide a smooth, silky texture and improve the skin feel of cosmetic products. It helps in retaining moisture, reducing skin roughness, and enhancing the overall appearance of the skin.
Used in Pharmaceutical Industry:
Cetyl Esters Wax is used as a binder, emulsifier, and consistency agent in the formulation of tablets, capsules, and topical medications. Its emulsifying properties help in stabilizing the mixture of oil and water-based ingredients, ensuring a uniform and consistent product.
Used in Textile Industry:
Cetyl Esters Wax is used as a finishing agent to impart water repellency, softness, and luster to fabrics. It helps in reducing the friction between fibers, enhancing the durability and overall quality of the textile products.
Used in Plastics and Rubber Industry:
Cetyl Esters Wax is used as a lubricant and release agent in the manufacturing of plastics and rubber products. It helps in reducing the friction between the materials and the processing equipment, ensuring a smooth and efficient production process.
Used in Food Industry:
Cetyl Esters Wax is used as a glazing agent, providing a shiny and smooth appearance to confectionery and bakery products. It also acts as a moisture barrier, extending the shelf life of the products by preventing them from becoming stale or hard.
Used in Agriculture:
Cetyl Esters Wax is used as a protective coating for fruits and vegetables, providing a barrier against water loss, microbial contamination, and mechanical damage. It helps in maintaining the freshness and quality of the produce during storage and transportation.
Production Methods
Cetyl esters wax is prepared by the direct esterification of the
appropriate mixtures of fatty alcohols and fatty acids.
Flammability and Explosibility
Nonflammable
Pharmaceutical Applications
Cetyl esters wax is a stiffening agent and emollient used in creams
and ointments as a replacement for naturally occurring spermaceti.
Cetyl esters wax is hydrophobic and has been proposed as a
suitable component of an ophthalmic gelatin-based, controlledrelease
delivery matrix.
The physical properties of cetyl esters wax vary greatly from
manufacturer to manufacturer owing to differences between the
mixtures of fatty acids and fatty alcohol esters that are used.
Differences between products appear most obviously in the melting
point, which can range from 43–47℃ (USP32–NF27 range) to
51–55°C, depending on the mixture. Materials with a high melting
point tend to contain predominantly cetyl and stearyl palmitates.
Safety Profile
An eye irritant. When heated to decomposition it emits acrid smoke and irritating fumes.
Safety
Cetyl esters wax is an innocuous material generally regarded as
essentially nontoxic and nonirritant.
LD50 (rat, oral): >16 g/kg
storage
Store in a well-closed container in a cool, dry place. Avoid exposure
to excessive heat (above 40℃).
Incompatibilities
Incompatible with strong acids or bases.
Regulatory Status
Included in the FDA Inactive Ingredients Database (topical
preparations). Included in nonparenteral medicines licensed in the
UK. Included in the Canadian List of Acceptable Non-medicinal
Ingredients.
Check Digit Verification of cas no
The CAS Registry Mumber 17661-50-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,6 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 17661-50:
(7*1)+(6*7)+(5*6)+(4*6)+(3*1)+(2*5)+(1*0)=116
116 % 10 = 6
So 17661-50-6 is a valid CAS Registry Number.

A convenient approach directly from triglycerides toward the producing of thia-wax esters as bio- and chemical raw materials
Y?ld?r?m, Ayhan,K?raylar, Kaan,?ztürk, Serkan
, p. 215 - 230 (2020)
Abstract: Practical and efficient method has been developed for the preparation of novel sulfur-containing esters from triglycerides as potential important industrial and biomaterials. The fact that these unusual compounds are not found in natural sources encourages both academic and industrial communities for their preparation with suitable chemical or enzymatic processes. In general, enzymatic processes requiring more laborious synthesis and product isolation stages. On the other hand, known chemical methods for the preparation of normal wax esters have several drawbacks cited in the present work. Therefore, the chemical method developed in the present study is environmentally benign and suitable for both small- and large-scale syntheses of normal and unusual wax esters. For this purpose, triglycerides were taken to the transesterification reaction in a solvent-free medium with synthetic thia-long-chain alcohols at a ratio of (1:3). In order to catalyze the reaction, newly synthesized bis-imidazole-based metal-free acidic ionic liquid was used and the thia-mono esters were obtained in a fairly short period of time (6?h) with good to excellent yields. The catalyst reuse and large-scale synthesis studies were also carried out. Graphic abstract: [Figure not available: see fulltext.].
PROCESS FOR PRODUCING CARBOXYLIC ACID ESTER AND ESTERIFICATION CATALYST
-
Page/Page column 12-13, (2008/06/13)
A process for carboxylic acid ester production by which a carboxylic acid ester comprising an alcohol and a carboxylic acid each having 10 or more carbon atoms can be produced in a high yield. The catalyst used can be reused. The process generates a small amount of wastes and is less apt to pose an environmental problem. Also provided is an esterification catalyst usable in the process. In the esterification of a C10 or higher carboxylic acid and a C10 or higher alcohol, use is made, as a catalyst, of a hydrate of a salt of at least one metal selected among aluminum, gallium, indium, iron, cobalt, nickel, zinc, zirconium, hafnium, and niobium.
