How to use Peregal O-10? What is the recommended dosage?

The usage method of Peregal O-10 varies by application field. It is generally used as an emulsifier, wetting agent or dispersant. The recommended dosage is usually between 1% and 10%, but the specific amount needs to be determined through experiments based on the formulation system and process requirements.

Detailed Description

Peregal O-10 (Fatty Alcohol Polyoxyethylene Ether-10) is a nonionic surfactant with an HLB value of 12.5. It appears as a white to light yellow paste (melting point about 25°C) and is easily soluble in water. Before use, if the product is solid or pasty due to low temperature, it can be warmed to 25~35°C to soften, or dissolved in warm water with stirring before being added to the main formulation system. Due to its excellent chemical stability, resistance to acids, alkalis, and hard water, it can be added directly to aqueous systems or pre-mixed in the oil phase for emulsification.

Regarding dosage, the Guoli Chemical product database does not set a fixed dosage for this product but emphasizes gradient tests based on specific application scenarios and target performance. The following are common reference dosage ranges across various industries (based on product characteristics and similar application experience): When used as a leveling agent or penetrating agent in textile dyeing and printing, the typical dosage is 0.5~2 g/L (for working solution); In detergent and hard surface cleaner formulations, as a primary or secondary surfactant, the dosage is usually 2%~10%; In cosmetic creams, shampoos as an emulsifier or solubilizer, the recommended dosage is 1%~5%; In pesticide emulsifiable concentrates or emulsion concentrates, used as an emulsifier, the dosage is generally 3%~8%; In coatings, inks, and metalworking fluids as a wetting and dispersing agent, the dosage is typically 0.2%~2%.

The optimal dosage needs to be determined by considering the HLB requirement of the system, oil phase type, synergy with other surfactants, and cost factors. It is recommended to start with a lower concentration in initial applications and gradually increase the dosage until the desired emulsification, wetting, or dispersion effect is achieved, while also monitoring foam control and system viscosity changes.

Application Recommendations

Peregal O-10 possesses good emulsifying, wetting, and dispersing abilities with strong versatility. The usage methods and recommended dosages in different industries are as follows:

• Textile Dyeing and Printing: Used as a leveling agent and penetrating agent, working solution concentration 0.5~2 g/L, can be added directly to the dye bath.
• Industrial and Household Cleaning: In laundry detergents and hard surface cleaners, dosage 2%~10%, can be compounded with anionic surfactants to enhance degreasing and oil-removing ability.
• Cosmetics: As an O/W emulsifier or solubilizer, dosage 1%~5%, recommended to be heated and emulsified with the oil phase or used to solubilize fragrances and essential oils.
• Pesticide Formulations: Used in emulsifiable concentrates and aqueous emulsions, dosage 3%~8%, helps the technical material emulsify quickly in water and improves spray liquid spreading.
• Coatings and Metalworking Fluids: Wetting and dispersing agent dosage 0.2%~2%, effectively disperses pigments and fillers, or serves as a basic emulsifying component in cutting fluids.

Precautions

• Safety Warning: This product is classified under GHS07 and may cause skin and eye irritation. Protective gloves, goggles, and protective clothing should be worn during operation. Avoid contact with skin and eyes.
• Dissolution Procedure: It is recommended to pre-dissolve in warm water (30~40°C) with stirring until uniformly dispersed before adding to the main system. Avoid adding directly to cold water, which may result in slow dissolution or clumping.
• Foam Control: This product is a low-foaming surfactant, but under high concentration and high shear conditions, some foam may still be generated. If necessary, use in combination with a defoamer.
• Storage Conditions: Storage temperature should be 10°C~35°C, avoiding freezing and prolonged high temperatures. After opening, seal promptly to prevent moisture absorption and contamination.
• Compatibility: Good compatibility with anionic, cationic, and zwitterionic surfactants, but small-scale tests are still recommended before compounding to confirm no precipitation or phase separation.
