MY9120 vs MY1836N: Whose powder dispersion effect is better?
I. Overview of powder dispersion properties of MY9120 and MY1836N
MY9120 and MY1836N are both high-quality cosmetic raw materials developed and produced by themselves. They are usually used to make powder-containing cosmetics such as sunscreen and foundation.Powder dispersion is the key to judging whether such raw materials are useful or not, which directly affects the texture of the finished product, the skin feeling used, and the final makeup effect.Fortunately, MY9120 has a good emulsifying effect and can be well matched with polar oils and fats. MY1836N is specialized in dispersing powders, and it is of plant origin, which has attracted a lot of attention.Let's just talk about dispersing powders. Who is the more powerful of these two raw materials and is more suitable for use in cosmetics containing powders?
II. Analysis of powder dispersion performance of MY9120
The INCI name of MY9120 is Sorbitan Isostearate, which is a synthetic compound with a clear composition and structure. It is a yellow liquid at 25℃.It is not only an easy-to-use water in oil emulsion, it can make a stable emulsifying system, and it can also help moisten and disperse the powder.In powder-containing cosmetics such as sunscreen foundation, MY9120 can reduce the strength of the powder particles sticking together, so that the powder spreads evenly in the oil phase, and there will be no agglomeration or uneven makeup.
Its dispersion effect is inseparable from its own physical and chemical properties.Its acid value does not exceed 8mgKOH/g, its saponification value is between 143-153mgKOH/g, and its hydroxyl value is in the range of 220-250mgKOH/G. These indicators ensure that it can be well combined with powder particles.Moreover, MY9120 can adapt to formulas with many polar oils, even if a lot of polar oils are added to it, it can stably disperse the powder.In addition, it supports the cold distribution process without high temperature heating, which can not only simplify the production steps, but also avoid high temperature affecting the dispersion effect of the powder.
However, it should be noted that MY9120 is mainly used as an
Emulsifier, and dispersing powder is only an accessory ability.If there is a lot of powder in the formula, the core is to disperse the powder well, then its effect may not be as symptomatic as a special dispersant.Also, MY9120 matches well with cationic ingredients. When used in hair care products, it can not only disperse the powder ingredients inside, but also make the cationic ingredients better adsorbed on the hair. Used with
Cationic Softener, the effect of conditioning hair can be better.
III. Analysis of powder dispersion performance of MY1836N
The INCI name of MY1836N is Polyhydroxystearic Acid, which is also a synthetic compound with a clear composition and structure. It is a yellow liquid at room temperature.Unlike MY9120, its core role in cosmetic formulas is to disperse the powder, which is its most important advantage.It can significantly reduce the viscosity of the dispersion system, break the state where the powder particles gather into a ball, and make the powder fine and uniform.
In the actual production scenarios of powder pulp grinding, high concealer foundation, and high multiples of sunscreen, MY1836N performs particularly well.It can quickly seep into the surface of the powder particles, change the surface tension of the particles, and prevent the particles from sticking together again, so that the product will be more delicate and smoother.Its acid value is controlled within 10mgKOH/g, which can be well matched with various powders and other ingredients in the formula, and it can also work synergistically with different emulsifiers and oils to stabilize the dispersion effect.
In addition, MY1836N is of plant origin, which meets the needs of people who like natural and gentle cosmetic raw materials.Its dispersion effect is not much affected by the formula system. Whether it is an oil-based formula or a water-oil mixed formula, it can stably disperse the powder.However, when storing, it should be noted that when the temperature is lower than 18℃, freezing and stratification may occur. This is a normal physical phenomenon. After heating and stirring, the dispersion performance will be restored and will not be affected.When used in the formula, it can be used with emulsifier makeup to make the formula more stable and the dispersion effect is better.
IV. Comparison and selection of powder dispersion properties of MY9120 and MY1836N
Core functional differences
MY1836N is a professional dispersant. The effect of dispersing powder is more symptomatic and the efficiency is higher. It is suitable for formulas with particularly high powder content and strict requirements for dispersing effect, such as high concealer foundations, powder pulp products, and sunscreen products with more powder.MY9120 is an emulsifier, which can disperse powders by the way. It is more suitable for formulas that require both emulsification and stability while taking into account powder dispersion, such as sunscreen and moisturizing foundations that are usually used.
Application scenario
MY9120 has both emulsifying function and dispersing powder. When making powder-containing cosmetics that need to be emulsified, it can simplify the formula and use less raw materials.MY1836N has better compatibility with various powders, and it is more flexible to use in formulas with more powders. It can also work with
Cetrimonium chloride in some special formulas to achieve the effect of dispersing the powder and conditioning at the same time.
Practical application adaptation
The recommended dosage range of MY9120 is relatively wide, between 0.3-3.0%, which is more cost-effective for formulas with low powder content.The recommended dosage of MY1836N is 1.0-10%. Although the dosage may be a little more in some scenarios with high dispersion requirements, it has a good dispersion effect and can reduce the dosage of other auxiliary ingredients. On the contrary, the overall formula cost can be balanced.
In the cosmetic raw material market, in addition to MY9120, there are many commonly used water in oil emulsifiers that are also used to make powder-containing products.Let's compare MY9120 with common similar products from the aspects of powder dispersion, compatibility, and production process adaptation to see where its advantages are.
Comparison of powder dispersion capacity
Compared with ordinary water in oil emulsifier, MY9120 has a better effect of wetting and dispersing powder.Although ordinary water in oil emulsifier can ensure basic emulsification stability, most of the dispersed powders are passively adapted. When encountering a formula with a large number of powders, it is difficult to solve the problem of particle agglomeration, and MY9120 relies on its unique molecular structure to combine more closely with powder particles.
Comparison of compatibility of polar oils and fats
Many water in oil emulsifiers are prone to unstable emulsification and failure of dispersed powders in formulas with more polar oils.However, MY9120 can adapt to environments with many polar oils and fats. In formulas containing polar oils such as jojoba oil and grape seed oil, the powder can still be stably emulsified and dispersed.This advantage makes it more flexible to use in moisturizing sunscreen and foundation products.
Process adaptability comparison
Most ordinary water in oil emulsifiers require a high-temperature heating process. High temperature not only increases energy consumption, but may also affect the dispersion effect of the powder and even destroy the stability of the active ingredients in the formula.MY9120 supports cold matching, which can complete the emulsification and dispersion of the powder at room temperature, simplifying the production process while retaining the effective ingredients of the product to the greatest extent.This is a great advantage for companies that want to improve production efficiency and make gentle formulas.
Comparison of additional functions
Ordinary water in oil emulsifier has a relatively single function, mainly to ensure stable emulsification.In addition to emulsifying, MY9120 can also disperse powders, help adsorb cationic components, and have more complete functions.Used in hair care products, it can disperse the powder at the same time, so that the cationic conditioning ingredients are better adsorbed on the hair, making the hair smoother and the repair effect is better. Used in makeup products, its versatility can also reduce the types of raw materials in the formula, reduce the complexity of the formula and production costs.
VI.Performance comparison of MY1836N and traditional powder dispersants
Traditional powder dispersants are used a lot in cosmetic formulas, but they have shortcomings in dispersion efficiency, compatibility, and gentleness.Let's compare MY1836N with traditional powder dispersants to see its technical advantages.
Dispersion efficiency comparison
Traditional powder dispersants often require long-term grinding and stirring to disperse the powder well, and the dispersed powder particles are easy to get together again.MY1836N can quickly penetrate to the surface of the powder particles, which reduces the strength of sticking together between the particles at once.At the same time, it can also form a stable dispersion system, effectively prevent the powder from agglomeration again, and extend the shelf life of the product.
Formula compatibility comparison
Some traditional powder dispersants are not well matched with oils and emulsifiers, which can easily make the formula layered and muddy, limiting its use scenarios.MY1836N has good fat solubility and can be perfectly matched with various oils, emulsifiers, and active ingredients. Whether it is an oil-based formula or a mixed water-oil formula, it can play a stable role and is suitable for sun protection, makeup, cleaning and other products.
Comparison of sensory quality improvement
Traditional powder dispersants have limited effect in improving the sense of use of the product, and some will make the product sticky and heavy.MY1836N can not only efficiently disperse the powder, but also improve the sense of use of the product, making the texture of the product more delicate and smooth. After applying makeup, it is natural to obey, without a heavy and sticky feeling, which can significantly enhance everyone's experience.
