Factory Supply Sucrose Stearate with CAS number 25168-73-4 is a high - quality chemical product. Sucrose stearate is an ester formed by sucrose and stearic acid. It is a non - ionic surfactant with excellent emulsifying, dispersing, and solubilizing properties.
Physical and chemical properties:
- Appearance: It is usually a white or off - white powder or waxy solid.
- Molecular formula: C₃₄H₆₆O₁₁
- Molecular weight: Approximately 646.88 g/mol
- Melting point: Around 55 - 75 °C
- Solubility: It has limited solubility in water but is soluble in organic solvents such as ethanol and acetone.
- It has good thermal stability, which allows it to maintain its performance in a certain temperature range.
1. Food industry:
- As an emulsifier, it can improve the stability of oil - in - water emulsions in food products. For example, in margarine and salad dressings, it prevents the separation of oil and water phases, ensuring a homogeneous texture.
- It can also act as a dispersant, helping to evenly distribute solid particles in liquid media, such as in chocolate milk to prevent the sedimentation of cocoa particles.
2. Cosmetics industry:
- In creams and lotions, sucrose stearate serves as an excellent emulsifier. It can reduce the surface tension between oil and water phases, creating a stable and smooth - feeling emulsion. This helps in better spreading and absorption of the cosmetic products on the skin.
- It can also improve the stability of formulations, preventing the growth of microorganisms to some extent due to its surfactant properties.
3. Pharmaceutical industry:
- As an excipient in tablets and capsules, it can improve the wetting and dissolution of drugs, enhancing the bioavailability of certain medications.
- In topical pharmaceutical preparations, it can be used as an emulsifier to prepare stable ointments and creams.
1. In food applications:
- First, determine the appropriate dosage according to the specific food product and relevant food safety regulations. Generally, the dosage ranges from 0.1% to 2% of the total weight of the product.
- Dissolve the sucrose stearate in a small amount of warm water or an appropriate solvent before adding it to the main food mixture. Stir thoroughly to ensure uniform dispersion.
2. In cosmetics:
- When formulating creams or lotions, add sucrose stearate to the oil phase during the heating process. Heat the oil phase to a temperature above the melting point of sucrose stearate (usually around 60 - 70 °C) and stir until it is completely dissolved. Then, slowly add the water phase while homogenizing to form a stable emulsion.
- The dosage usually ranges from 1% to 5% depending on the desired properties of the cosmetic product.
3. In pharmaceutical applications:
- For tablet formulations, mix sucrose stearate with other excipients and the active pharmaceutical ingredient thoroughly during the granulation process.
- In topical preparations, follow similar procedures as in cosmetics, with dosage determined by the specific requirements of the drug delivery system.
1. Food case: A food company producing mayonnaise was facing the problem of oil separation during storage. By adding 0.5% sucrose stearate to the formula, they were able to achieve a stable emulsion. The mayonnaise maintained its homogeneous texture even after several months of storage, resulting in increased customer satisfaction and reduced product returns.
2. Cosmetics case: A skincare brand launched a new moisturizing cream. By using 3% sucrose stearate as an emulsifier, they created a cream with a smooth and luxurious texture. The cream spread easily on the skin and was quickly absorbed. The product received positive feedback from consumers, and sales increased significantly within a short period.
3. Pharmaceutical case: A pharmaceutical company was developing a new oral tablet for a poorly water - soluble drug. By incorporating 1% sucrose stearate in the formulation, the dissolution rate of the drug was improved by 30%. This led to better bioavailability of the drug, enhancing its therapeutic
