1,2-Octanediol Uses

1. Synthetic fragrance industry
In the field of synthetic fragrances, 1,2-octanediol serves as a precursor or intermediate for synthetic fragrances and participates in the synthesis of various fragrance compounds. The unique dihydroxyl group in its molecular structure allows it to participate in various chemical reactions such as aldol condensation and esterification to generate compounds with specific aromas. These compounds are widely used in products such as perfumes, toiletries, and air fresheners.

2. Lubricant additives
In the field of lubricating oil additives, 1,2-octanediol can be used as an additive to improve the low-temperature fluidity of lubricating oil and improve its anti-wear performance and oxidation resistance due to its excellent lubricity and stability. This helps extend the service life of mechanical components and reduces wear, which is especially important in precision machinery and extreme working conditions.

3. Plasticizer
As a plasticizer, 1,2-octanediol can increase the flexibility, ductility and processing properties of plastics. It has good compatibility with polymers such as polyvinyl chloride (PVC) and can effectively reduce the glass transition temperature of plastic products and improve their performance at low temperatures. It is suitable for the production of plastic products such as wires and cables, films, and hoses.

4. Adhesive
In adhesive formulations, 1,2-octanediol can adjust the curing speed and increase the initial bonding force and final strength of the adhesive. As a modifier, it can improve the water resistance and weather resistance of the adhesive. It is suitable for bonding wood, paper, metal and other materials. It is especially widely used in the construction, furniture manufacturing and packaging industries.

5. Surfactants and emulsifiers
Because its molecular structure contains both hydrophobic and hydrophilic groups, 1,2-octanediol can be used as a raw material for special surfactants to improve the detergency and emulsion stability of detergents and cleaners. In cosmetics and personal care products, it helps disperse oily ingredients to give products a finer, more even texture.

6. Medicine and Biotechnology
In the pharmaceutical field, 1,2-octanediol can be used as an intermediate or excipient in drug synthesis, as well as as a solvent or stabilizer in drug delivery systems due to its low toxicity and good biocompatibility. It may also play an important role in the formulation of biological products such as vaccines and antibiotics to enhance the stability and biological activity of the drugs.

7. Other industrial applications
1,2-Octanediol may also be used in textile auxiliaries, leather treatment agents, agricultural chemicals and other fields as a wetting agent, softener or preservative to improve product performance or extend product life.

Prominent Applications of 1,2-Octanediol in Cosmetics

1. Moisturizer
1,2-Octanediol has excellent moisturizing properties and can help the skin maintain moisture balance. As a humectant, it attracts and locks moisture to the surface of the skin, reducing transepidermal water loss (TEWL), thereby improving the skin’s moisture and softness, and giving the skin a sustained moisturizing effect.

2. Viscosity regulator
In cosmetic formulations, 1,2-octanediol can be used as an effective viscosity modifier. It thickens and stabilizes products, making products such as lotions, gels and creams easier to apply and more comfortable without leaving a greasy feeling on the skin.

3. Preservatives
With mild antibacterial and antiseptic properties, 1,2-octanediol can help inhibit the growth of microorganisms in cosmetics and extend the shelf life of the product. It is often used in combination with other preservatives to form a more efficient and mild preservative system, which is especially suitable for products with sensitive skin.

4. Skin conditioners
Due to its mild nature, 1,2-octanediol can help condition and improve skin texture. It can promote the health of the stratum corneum and make the skin look smoother and more delicate. It can also help other active ingredients penetrate the skin better and enhance the overall effectiveness of the product.

5. Security and Compatibility
According to the cosmetic ingredient assessment (as stated in the CIR report), the use of 1,2-octanediol in cosmetics is considered safe, and there are no obvious safety issues even at higher concentrations (such as 5%). Its good skin compatibility means it is suitable for use in cosmetic formulations for a wide range of skin types.

6. Environmental protection and sustainability
As a relatively mild and biodegradable chemical raw material, 1,2-octanediol is in line with the modern cosmetics industry’s pursuit of environmental friendliness and sustainability, and helps brands create a green, low-irritation product image.
