1. properties of dodecanol esters

Chemical Properties

Dodecanol ester (Dodecyl alcohol ester), also known as lauryl ester, is an ester compound formed by the reaction of lauryl alcohol and organic acids. Its formula is the C12H25OH C(O)R, where R represents various organic acid groups. The dodecanol ester has a higher molecular weight and a longer carbon chain, giving it a certain hydrophobicity and lower polarity.

Physical Properties

Dodecyl alcohol ester is usually a colorless to pale yellow transparent liquid at room temperature, with a slight ester-specific odor. Its density is lower than water, the boiling point is usually higher, about 250-300 degrees Celsius. Due to the long chain structure, the viscosity of the dodecanol ester is higher, but it still has good fluidity. It has good chemical stability and is not prone to oxidation or decomposition reactions.

2. dodecanol ester use

Cosmetics and Personal Care Products

Dodecyl alcohol esters are widely used in the cosmetics and personal care industries, mainly as emulsifiers, lubricants and conditioners. Due to its good skin compatibility and moisturizing effect, it is widely used in lotions, creams, shampoos and conditioners. It can improve the texture of the product, making it easier to apply and absorb.

Industrial Lubricants

In the industrial field, dodecanol esters are used as high-performance lubricants and lubricating oil additives. Its good lubricity and thermal stability make it suitable for equipment lubrication under high temperature and heavy load conditions. The environmentally friendly properties and biodegradability of dodecanol esters also make them a green alternative to traditional mineral oils.

Food and medicine field

Dodecanol esters are also used in food and pharmaceutical fields, mainly as carriers and additives in food additives and pharmaceutical preparations. In food, it can be used as an anti-caking agent and surfactant to improve the texture and stability of food. In medicine, it acts as a matrix and excipient for pharmaceutical preparations to improve the bioavailability and stability of drugs.

3. dodecanol ester upstream and downstream raw materials

Upstream raw materials

The production of dodecanol esters relies primarily on two key raw materials: lauryl alcohol and organic acids. Lauryl alcohol is a long-chain fatty alcohol, which is mainly derived from the hydrolysis and refining process of natural oils such as coconut oil and palm kernel oil. Commonly used organic acids include acetic acid, stearic acid and various fatty acids, which can be obtained by chemical synthesis or natural extraction.

Downstream Products

The downstream products of dodecanol esters are mainly various fine chemical products and consumer products, such as the above-mentioned cosmetics, lubricants, food additives and pharmaceutical preparations. Due to its excellent physical and chemical properties, dodecanol ester is also used as a modifier for polymer materials and plastic plasticizers to improve the flexibility and durability of materials.

4. dodecanol ester storage method

Storage conditions

Dodecanol esters should be stored in a dry, well-ventilated warehouse, away from direct sunlight and high temperatures. The storage temperature should be controlled within the normal temperature range, generally not exceeding 40 degrees Celsius, to prevent product degradation and performance loss. Storage containers shall be of corrosion resistant material such as stainless steel or high density polyethylene to ensure a good seal against the ingress of moisture and impurities.

Safety measures

In the process of storage and transportation, the chemical safety management regulations should be strictly observed to prevent leakage and pollution. Operators should wear appropriate protective equipment such as gloves, goggles and protective clothing to avoid skin and eye contact. When leakage occurs, measures should be taken quickly to clean up, using adsorption materials such as sand or activated carbon for treatment to prevent diffusion and environmental pollution.

Transportation requirements

Dodecanol ester is a non-dangerous goods, but it is still necessary to pay attention to prevent mechanical damage and leakage during transportation. The means of transport shall have good ventilation and moisture resistance and avoid mixing with chemicals such as strong oxidants, acids and alkalis. For bulk transportation, a professional chemical transportation company should be selected to ensure safe transportation and standardized operation.

5. market prospects and trends
