Water in oil (W/O) emulsifying system is widely used in sunscreen products, makeup, high-end creams and high-water-content care products because of its excellent water resistance, makeup retention and moisture.The stability of the emulsifying system, skin feeling performance and formula compatibility directly determine the quality and market competitiveness of the final product.Among the many W/O
Emulsifier combinations, the main and auxiliary combination of OILREE® MY935 (peg-30 dipolyhydroxystearate) and OILREE® MY983 (sorbitan sesquioleate), with complementary characteristics, convenient use and excellent application results, provides formulators with a choice that combines stability and practicality.
As the core combination in the water in oil emulsification system, the reason why MY935 and MY983 can achieve efficient synergy lies in the fact that the characteristics of the two are highly complementary, and they assume the key roles of main emulsification and auxiliary emulsification respectively. They perform their respective duties and bless each other, fundamentally solving the limitations of a single emulsifier in terms of stability, skin feeling, and compatibility.To understand the logic of the combination of the two, it is first necessary to clarify their core characteristics and advantages.
Complementary characteristics
In the W/O emulsifying system, the main emulsifier is the core of the emulsifying structure, which is responsible for uniformly wrapping the aqueous phase in the oil phase to form stable emulsion particles.The co-emulsifier assists the main emulsifier to optimize the interface structure, improve the stability of the system, and at the same time improve the skin feel of the product and the adaptability of the formula.The combination of MY935 and MY983 perfectly fits this core requirement.
OILREE® MY935: Efficient and stable W/O main emulsifier core
As the main emulsifier in the system, MY935 has the INCI name peg-30 dipolyhydroxystearate, and its appearance is brown paste. The packaging specifications are divided into 20kg/barrel and 190kg/barrel, which are suitable for different needs.As the main emulsifier of water in oil, the core advantages of MY935 are concentrated in three aspects: emulsifying ability, temperature stability, and compatibility, which builds a solid foundation for the entire emulsifying system.
First of all, MY935 has a very strong emulsifying ability, has a high internal phase volume, can efficiently carry a high proportion of internal phase moisture, and can easily prepare a W/O emulsion with a high aqueous phase ratio.Its most prominent feature is that the particle size of fine emulsified body fluid droplets is not limited by the polarity of the external phase grease. Whether it is polar grease or non-polar grease, it can achieve good emulsification effect and can be adapted to a variety of oil phase systems, greatly improving the flexibility of the formula.This feature allows formulators to design products without being overly limited to the choice of oils, and can freely match oil ingredients according to the needs of product efficacy. For example, with
Isododecane to enhance the lightness of the product, or with
Butyl stearate to optimize the skin feeling, there is no need to worry about the problem of unstable emulsification.
Secondly, MY935 has excellent high temperature stability, which allows it to adapt to various complex environments in the production, transportation and storage of cosmetics.In the production process, many W/O system products need to go through the filling and heating process. MY935 can still maintain stable emulsifying properties in high temperature environments, and there will be no problems such as emulsification failure and stratification due to temperature increase.During transportation and storage, even in the face of high temperature environments, product stability can be ensured and quality problems such as water precipitation and agglomeration can be avoided.At the same time, MY935 can also be used to prepare liquid low-viscosity emulsions with excellent temperature stability, especially suitable for mobile products such as sunscreen emulsions, which can ensure the consistency of the texture of the products at different temperatures.
In addition, MY935 has good compatibility with various active ingredients, an advantage that is particularly important in the formulation of efficacy-based products.Nowadays, more and more cosmetics add various active ingredients to achieve whitening, anti-aging, repairing and other effects, while many active ingredients have poor stability and can easily react with emulsifiers, resulting in loss of efficacy or system instability.MY935 can coexist amicably with a variety of active ingredients without affecting its efficacy. At the same time, it can avoid the failure of emulsification caused by the interaction of ingredients, which provides convenience for the formulation design of efficacy-based W/O products.
OILREE®MY983: The best choice for precision-assisted W/O emulsifiers
Matching the main emulsifying role of MY935, MY983 is used as a
Water in oil emulsifier. The INCI name is sorbitan sesquioleate. The appearance is amber liquid. The packaging specifications are divided into 25kg/barrel and 190kg/barrel, which are complementary to the packaging specifications of MY935.The core role of MY983 is to assist the main emulsifier MY935 to optimize the stability and skin feel of the emulsifying system, while enhancing the adaptability of the formula. Its advantages are perfectly complementary to MY935 and jointly improve the overall performance of the emulsifying system.
As an emulsifier, the core function of MY983 is to assist the main emulsifier to further stabilize the interface structure.In the W/O emulsifying system, although the interfacial membrane constructed by a single main emulsifier can achieve the basic emulsifying effect, in long-term storage or complex environments, the interfacial membrane may still be fragile, emulsion particles coalesce and other problems, resulting in system stratification and water analysis.MY983 can be embedded in the interfacial membrane formed by the main emulsifier to enhance the flexibility and strength of the interfacial membrane, reduce the risk of system stratification or water analysis, and extend the shelf life of the product.This auxiliary stabilization effect makes the stability of the emulsifying system significantly improved after the combination of MY983 and MY935.
In addition to its stabilizing effect, MY983's regulating effect on the skin feeling of the formula is also particularly prominent.Many W/O system products, especially cream products with a high emulsification ratio, are prone to heavy and sticky skin sensations, which affect the consumer experience.MY983 can improve this heavy feeling, make the product more malleable and easier to push away, not only to ensure moisture, but also not to produce a sticky feeling.This skin-feeling optimization effect enables the combined emulsifying system to be adapted to more product types, whether it is a lightweight emulsion or a heavy cream.For example, when combined with moisturizing ingredients such as
Bis diglyceryl polyacyladipate 2, MY983 can further optimize the moisture and ductility of the product, making the product feel more delicate.
Summary of core advantages
First, the emulsification stability is significantly improved.After the combination of the two, MY935 builds a stable W/O emulsified structure, and MY983 enhances the flexibility and strength of the interfacial membrane, forming a dual stability guarantee, effectively reducing system stratification, water analysis, agglomeration and other problems.
Second, the skin feeling experience is optimized and upgraded.The addition of MY983 has effectively improved the heavy and sticky feeling that a single MY935 emulsifying system may bring, making the product more malleable and easier to push away. After application, a thin and breathable protective film is formed, which takes into account the moisture and freshness, and enhances the consumer experience.Whether it is a lightweight lotion or a heavy cream, the ideal skin feeling performance can be achieved by adjusting the ratio of the two.
Third, the powder dispersion ability is outstanding.After the combination of the two, they can give full play to their respective powder dispersion advantages, effectively solve the dispersion problems of toner, inorganic powder, etc. in the oil phase, avoid powder agglomeration and sedimentation, and ensure uniform product texture, stable color rendering, and uniform sunscreen effect.
Recommended application scenarios
