Basic Information
- CAS Number: 68155 - 09 - 9
- Chemical Name: Cocamidopropyl dimethylamine oxide
- English Name: Cocamidopropyl Amine Oxide
- Molecular Formula: RCONH(CH?)?N(CH?)?O (where R represents the coco group)
2. Product Properties
- Appearance: Usually presents as a colorless to slightly yellowish transparent liquid.
- Odor: Odorless or with a faint, characteristic smell.
- Solubility: Highly soluble in water, which enables it to be easily incorporated into aqueous - based formulations.
3. Production Method
Cocamidopropylamine oxide is synthesized by reacting dimethylaminopropylamine with fatty acids derived from coconut oil to form an amide. Subsequently, this amide is oxidized using hydrogen peroxide or other suitable oxidizing agents. The reaction can be represented as follows:
- First, the reaction between coconut - derived fatty acids (R - COOH) and dimethylaminopropylamine (H?N(CH?)?N(CH?)?) forms an amide:
- R - COOH + H?N(CH?)?N(CH?)? → RCONH(CH?)?N(CH?)? + H?O
- Then, the amide is oxidized by hydrogen peroxide (H?O?) to produce cocamidopropylamine oxide:
- RCONH(CH?)?N(CH?)? + H?O? → RCONH(CH?)?N(CH?)?O + H?O
4. Key Performance Features
- Gentleness: Exhibits mildness to the skin, making it an ideal ingredient for sensitive - skin - targeted products, such as baby shampoos and facial cleansers. It significantly reduces the risk of skin irritation, providing a comfortable experience for users.
- Foaming Ability: It has excellent foaming properties, capable of generating rich, dense, and stable foam. In products like shampoos and body washes, this property enhances the user experience, and the foam can effectively carry away dirt and impurities from the skin and hair.
- Thickening Property: Functions as an effective thickening agent. When added to formulations, it can adjust the viscosity of products, helping to create the desired texture. For example, in liquid soaps, it can make the product thicker and more viscous, which is more convenient for use.
- Stability: Maintains good stability in both acidic and alkaline media, and is not affected by hard water. This stability ensures that the product performance remains consistent under different environmental conditions, whether in acidic hair - care products or alkaline - based industrial cleaners.
- Compatibility: Can be well - combined with anionic, cationic, amphoteric, and non - ionic surfactants. It also shows good compatibility with various dyes and other cosmetic raw materials. This wide compatibility allows for greater flexibility in formulating complex product systems.
- Cleansing and Conditioning: As a surfactant, it reduces the surface tension of liquids, effectively removing dirt, oils, and stains. In hair - care products, it also provides conditioning effects, making hair smoother, shinier, and more manageable.
5. Application Scope
- Shampoos: It is widely used in shampoos to improve foam quality, provide hair - conditioning effects, and reduce the irritation of other surfactants. It helps to clean the hair thoroughly while leaving it soft and shiny.
- Body Washes and Shower Gels: In body washes and shower gels, cocamidopropylamine oxide contributes to rich and stable foam, and its mild nature makes it suitable for use on the skin. It can also enhance the cleansing power and leave the skin feeling clean and moisturized.
- Facial Cleansers: For facial cleansers, especially those designed for sensitive skin, it provides gentle cleansing without stripping the skin of its natural moisture. It can effectively remove dirt, oil, and makeup residues while maintaining the skin's natural barrier function.
- Baby Care Products: Given its mildness, it is an important ingredient in baby shampoos, body washes, and bubble baths. It ensures the safety and comfort of babies' delicate skin and hair during the cleansing process.
- Shaving Products: In shaving foams and gels, it helps to create a rich and lubricating foam, which reduces friction during shaving, preventing skin damage and providing a smooth shaving experience.?
- As a Calcium Soap Dispersant: It can be used to disperse calcium soaps, which are formed when soap reacts with hard water. This property is useful in improving the performance of soaps in hard - water areas.
- In Fiber/Fabric Treatment: Serves as an antistatic and softening agent for fibers and fabrics. It reduces static electricity in textiles, making them more comfortable to wear and handle, and also imparts a soft feel to the fabric.
- In Rubber Industry: Functions as a gel emulsifier in the rubber industry, helping to stabilize emulsions and improve the processing properties of rubber compounds.
- As a Wool Shrink - proof Agent: Can be used to treat wool to prevent shrinkage during washing and maintain the shape and quality of woolen products.
- In Fire - fighting Foam and Pesticide Synergists: In fire - fighting foams, it helps to generate stable foam that can effectively extinguish fires. In pesticides, it can act as a synergist to enhance the efficacy of pesticides.
6. Recommended Usage Concentration
Typically, the recommended usage concentration ranges from 1% to 5%. However, the exact amount can be adjusted according to the specific foaming and cleansing requirements of the product. For example, in products where strong foaming and high - level cleansing are needed, a relatively higher concentration may be used, while for more gentle - action products, a lower concentration is appropriate.
7. Storage Conditions
- Store in a tightly - sealed container to prevent air and moisture from entering, which could affect the product quality.
- Keep it in a dry, cool place at room temperature. Avoid exposure to direct sunlight and high temperatures, as excessive heat may cause decomposition or changes in the product's properties.
- The shelf life of cocamidopropylamine oxide is usually 12 - 24 months under proper storage conditions.
