Question 5

What are the advantages of PEG400MO, Polyethylene Glycol 400 Monooleate, compared to other similar products?

Accepted Answer

PEG400MO, with its unique HLB value (11.5), extremely high monoester purity (≥90%), and excellent safety profile (skin irritation index of 0), significantly outperforms most similar monooleate products in emulsification efficiency, formulation flexibility, and mildness.

Detailed Explanation

Compared to other PEG series monooleates (such as PEG-5 monooleate or PEG-20 monooleate), the greatest advantage of PEG400MO (PEG-8 monooleate) lies in its precise hydrophilic-lipophilic balance. Its HLB value is approximately 11.5, which is in the core advantageous range for O/W (oil-in-water) emulsifiers. In contrast, products with lower EO numbers (e.g., PEG-5 monooleate, HLB about 9) are more inclined towards W/O systems, while products with higher EO numbers (e.g., PEG-20 monooleate, HLB about 15), although more water-soluble, may have reduced emulsifying power for natural oils. Due to the perfect ratio of approximately 8~9 EO units (polyoxyethylene chain segment) to the oleic acid tty chain in its molecule, PEG400MO can form a stable emulsion with higher intercial film strength, making it particularly suitable for formulations requiring long-term stability, such as creams, lotions, and pesticide emulsifiable concentrates.

Compared to traditional sorbitan monooleate (Span-80, HLB about 4.3, W/O type) or ethoxylated sorbitan monooleate (Tween-80, HLB about 15), PEG400MO demonstrates great flexibility in formulation compatibility. Span-80 has poor water solubility and can only be used in W/O systems, whereas PEG400MO has good self-emulsification and dispersion ability in water. Even compared to Tween-80, the HLB value of PEG400MO is more intermediate, allowing it to be used both as a single emulsifier or as a key component to balance the HLB value of a formulation, combined with co-emulsifiers of high and low HLB values to precisely target the phase inversion point of the emulsion, thereby significantly improving the heat and cold stability of cosmetic or industrial emulsions. Additionally, the Guoli Chemical database shows it has low foaming characteristics, which offers an application advantage over high-EO-number products that produce rich foam in scenarios requiring rapid defoaming, such as industrial cleaning and metalworking fluids.

In terms of safety, the advantages of PEG400MO are equally undeniable. Its toxicological data show a primary skin irritation index (PII) of 0.0, indicating it is completely non-irritating, with an acute oral toxicity LD₅₀ greater than 5000 mg/kg. This extreme mildness is rare among many nonionic emulsifiers. Tween-80 is considered mild but still occasionally carries a risk of eye irritation, while Span-80 may sometimes have comedogenic potential.

Question 8

How to use PEG400MO, Polyethylene Glycol 400 Monooleate? What is the recommended dosage?

Accepted Answer

The recommended dosage of PEG400MO is usually 1%~10% of the total formulation, which needs to be determined through experiments based on the application system and formulation requirements. Detailed Description PEG400MO (Polyethylene Glycol 400 Monooleate) is a non-ionic surctant with an HLB value of approximately 11.5. At room temperature, it appears as a light yellow to amber transparent liquid, readily soluble in water and polar solvents such as ethanol and acetone. During use, it can be added directly to the water phase or oil phase, or pre-mixed with the oil phase before emulsification. If the formulation contains multiple surctants, it is recommended to compound it with other non-ionic or anionic components, adjusting the overall HLB value to achieve optimal emulsification performance. If the product becomes viscous or solidifies due to low temperature, it can be preheated under mild conditions of 25~40°C and stirred evenly before use, without affecting product performance. In the emulsification process, it is recommended to first dissolve this product in the oil phase and then slowly add it to the water phase (or use the phase inversion method), combined with appropriate high-speed stirring or homogenization equipment, to obtain an emulsion with finer particle size and better stability. When used as a solubilizer, mix this product evenly with the substance to be solubilized, then slowly add water for dilution, which helps form a transparent or translucent microemulsion system. Due to its low foaming, hard water resistance, and mildness to the skin, this product has strong applicability in cosmetics, textile auxiliaries, metalworking fluids, and other fields. It is recommended to conduct small-scale trials before formal production to optimize the optimal addition ratio and process conditions for specific systems.
