What are the core product features of OSMFACT® MY1821-95E?
MY1821-95E stands out because of its balanced and excellent product characteristics, which accurately matches terminal needs.：
1.Excellent softness and performance
The long chain of bis-octyl alkyl in the molecular structure can form a uniform lubricating film on the surface of the fabric or hair, which helps to reduce the coefficient of friction between the fibers and brings an ideal soft experience.According to the application law of product characteristics, at a conventional concentration of 0.5%, such double-long-chain cationic surfactants can usually significantly improve the bending stiffness of cotton fabrics and significantly improve the softness. When used in hair care products, it can also effectively optimize the dry and wet combing properties of the hair, reduce the sense of pulling during combing, and at the same time form a certain protection for the mechanical strength of the hair.This softness is not a short-term smooth surface, but is due to the good adsorption and binding of molecules to the fabric and hair matrix. After multiple washes, it can still retain a good softening effect.
2.Powerful antistatic
Cationic groups can effectively neutralize the negative charge on the surface of the matrix and reduce the accumulation of static electricity.When applied to conditioner, it can quickly dissipate static electricity on the surface of the hair, avoid knotting, skin sticking and other problems, and make combing smoother.
3.Good chemical stability
The active ingredients are not easy to decompose in the range of pH value 6-8, and can be adapted to most care product formulation systems. Store at room temperature, avoid light, and airtight conditions to avoid long-term higher than 30℃. Stable performance, no discoloration, agglomeration, activity attenuation and other problems.This stability allows it to be adapted to a variety of end product forms such as liquid, concentrated, and solid, expanding application scenarios.
4.Easy to disperse, easy to operate, stirring in warm water at 40-50℃ can disperse quickly, without additional dispersant or high temperature heating, using ethanol as a solvent can further improve the dissolution rate and form a stable concentrated slurry.This feature not only simplifies the production process of manufacturers, reduces energy consumption and costs, but also provides convenience for small batch deployment or DIY care products.
5. Clear compatibility characteristics
It has good compatibility with cationic surfactants (such as
Cetrimonium chloride), nonionic surfactants and most functional additives, and can be synergistic, but it is incompatible with anionic surfactants and fluorescent agents. After mixing, it will precipitate and agglomeration, resulting in product failure. The relevant ingredients need to be strictly isolated during formula design and production.

OSMFACT® MY1821-95E processing technology
As a high-concentration cationic active substance, the processing technology directly affects the performance and stability of the end product. The following are the key points.：
1. Dissolution and dispersion process
The core is to ensure that the raw materials are evenly dispersed and avoid agglomeration or gelation problems.Conventional warm-water dispersion method can be used, with deionized water at a suitable temperature, and stirred at medium speed for a period of time to allow the raw materials to be fully dissolved. The raw materials can also be mixed with an appropriate amount of ethanol to make a certain concentration of concentrated slurry, and then gradually added to the main aqueous phase.When producing high-viscosity
cationic fabric softener, it is recommended to use a high-shear emulsifying machine for processing to form a stable microemulsion system.During operation, care should be taken to avoid rapid stirring with cold water, and at the same time control the heating temperature, which should not be too high.
2. Compounding and compatibility process
When this raw material is combined with Cetrimonium chloride and cationic ingredients, it helps to improve the softening and conditioning effect of the product; when combined with Amino silicone emulsion, it is recommended to premix it evenly in a separate container before adding it to the main formula system.Special attention should be paid to the fact that direct contact with anionic surfactants is strictly prohibited. If the formula system contains anionic components, it needs to be fully diluted or neutralized before adding the raw material slowly and stirring continuously. Before compatibility with optical brighteners, it is recommended to conduct a small-scale test to determine the appropriate addition ratio and sequence.
3. Dilution and filling process
The dilution process should follow the principle of ”slow addition, slow stirring, gradient dilution", control the speed of diluent addition, avoid excessive concentration changes, and monitor the viscosity and concentration of the system in real time.The finished product can be filtered before filling to remove possible impurities. The filling environment needs to be kept clean and hygienic. For products that are easy to oxidize, nitrogen-filled filling methods can be considered. Control the speed during filling to reduce foam generation and ensure that the net content of the product meets the relevant requirements.
4. Storage and stabilization process
The raw materials are packed in sealed packages. When storing, they need to be stored in a dark, dry and ventilated environment, control the appropriate storage temperature, and stay away from oxidants and acidic substances.In order to improve the storage stability of the end product, an appropriate amount of antioxidant can be added to the formula. When the product is stored for a long time, the storage tank can be stirred slightly regularly to prevent stratification.
5. Quality control and inspection process
The raw materials are checked for COA and sampled for testing, the uniformity, pH value and viscosity of the slurry are tested after pre-dispersion, and the finished product is tested for pH value, active substance content, viscosity, centrifugal stability, high and low temperature stability and other indicators; personal care products also need to be tested for skin irritation and microbial limit to ensure safety standards.
In general
OSMFACT® MY1821-95E has become a high-quality raw material for the textile care and personal care industry with 95% high purity, excellent soft and antistatic properties, wide compatibility and convenient processing characteristics.It accurately matches the needs of end products, has multiple application scenarios, and a mature processing technology system ensures stable product quality and performance.
