Why Is SMOICON ® MY651 a Reliable Choice for Cosmetic Formulations?
As a high-performance organic silicon material in the field of beauty and personal care, SMOICON ® The application of MY651 (
Cyclopentasiloxane&DIMETHICONE CROSSPOLYMER) in skincare, cosmetics, antiperspirant fragrances and other products is constantly increasing. It is gradually replacing traditional greasy moisturizers or single function silicone raw materials, becoming the preferred choice for formulators who pursue high-quality skin feel. Behind this trend is its comprehensive advantages in sensory experience, formula compatibility, and functional diversity.
Firstly, MY651 can provide a unique and outstanding skin sensation experience. It is a cross-linked organic silicon polymer dissolved in cyclopentasiloxane, with a velvet like texture, a powdery texture, and a dry and non greasy appearance. Adding it to cosmetics can effectively reduce the stickiness of the formula. In the practical application of moisturizing cream, liquid foundation and other products, a thin thin film will be formed on the skin surface after application to avoid the thick or greasy residue of mineral oil and other ingredients. If used in combination with nutmeg acid and nutmeg ester, it can further balance the skin feel, enhance moisturizing durability while maintaining a dry texture.
Secondly, MY651 has excellent formula thickening and stability capabilities. It can thicken anhydrous formulas and act on water in oil emulsifiers to help adjust product viscosity to the optimal range. Taking lipstick formula as an example, adding 10% -15% MY651 can prevent the product from easily breaking due to being too thin, while maintaining a smooth application texture. Its cross-linked polymer structure can enhance formula stability and reduce the risk of delamination or precipitation during long-term storage. Under normal use, there will be no dangerous reaction, and there will be no dangerous decomposition products when stored and operated according to regulations. This is especially important for products with long shelf life such as sunscreen and liquid foundation.
Furthermore, it has good compatibility and processing flexibility. MY651 is compatible with various cosmetic ingredients, does not react with other ingredients to cause discoloration or performance degradation, and supports cold and hot mixing processes. The formulator can add directly at room temperature without additional heating, simplifying the production process and reducing energy consumption. This flexibility is suitable for small-scale trial production and can also meet the needs of large-scale production. If the formula needs to improve the emulsification effect and is used in combination with
Emulsifying wax, the stability of the system can be further optimized.
In terms of safety, MY651 meets the regulatory requirements for cosmetics. The safety technical manual data shows that there is no acute oral toxicity (LD50>5000mg/kg), no irritation to the skin and eyes, and no need for danger labels. Its safety also makes it suitable for use in sensitive muscle formulations.
With its advantages in skin feel, formula stability, compatibility, and safety, MY651's position in cosmetic formulas is constantly consolidating.
Which Cosmetic Formulations Benefit Most from SMOICON ® MY651？
SMOICON ® MY651, with its unique sensory characteristics and formula adaptability, has become a multifunctional ingredient in the field of beauty and personal care.
Skincare products are one of its core application areas. It can effectively reduce the sticky feeling of the formula, so it can replace some oil-based emollients in moisturizing cream and lotion, reducing the greasy feeling while maintaining a smooth feeling. For example, adding MY651 to moisturizing creams for oily skin can make the product light and non greasy. If used in conjunction with
GLYCERETH 26, it can increase long-lasting moisturizing power on the basis of velvet skin sensation. In the essence liquid, it can be used as a texture modifier to enhance the ductility; In exfoliating products, the powdery texture can reduce particle friction and decrease irritation.
Makeup is another important application category. In liquid foundation and concealer, it can enhance the ability of sticking to the skin and maintaining makeup. The velvet texture helps to blur pores and fine lines. In lip gloss or lipstick, it can reduce stickiness and enhance smoothness; In eye shadow, as an adhesive, it can improve pigment dispersion and reduce flying powder.
The antiperspirant fragrance products also benefit from the dry and non greasy properties of MY651. Adding to solid or rolling antiperspirants can improve the application feel, prevent white residue, and ensure even distribution of active ingredients.
Overall, SMOICON ® MY651 is suitable for heavy, lightweight, non sticky, and long-lasting cosmetic products. If combined with thickeners such as
Peg 150 pentaerythrityl tetrastearate, the texture can be further optimized.
What Quality-Related Precautions Should Be Taken When Using SMOICON ® MY651？
Improper handling during formula design and storage may lead to issues such as decreased skin feel, formula layering, or shortened shelf life. Understanding key precautions is crucial.
Firstly, it is important to pay attention to the amount of addition and mixing method. Exceeding the reasonable range may result in the product being too heavy. Regardless of cold or hot mixing, it is necessary to stir at a moderate speed to avoid introducing bubbles or uneven dispersion due to high speed. During cold mixing, the oil phase can be directly added. During hot mixing, the heating temperature should not exceed 45 ℃ to prevent volatilization or structural damage.
Secondly, attention should be paid to the pH value and ionic strength of the formula. MY651 is stable within the pH range of 6.5-8.0. If the pH is too low, it may affect the stability of cross-linked polymers and weaken the thickening effect. High concentration electrolytes may cause them to aggregate and stratify, and the system may need to be adjusted if necessary.
Storage conditions are equally critical. The product should be kept away from high temperatures (>40 ℃), high humidity, or direct sunlight. It should be stored at room temperature, away from light, and sealed. The temperature should be ≤ 30 ℃. High temperature will accelerate the volatilization of cyclopentasiloxane, causing the product to thicken. It is recommended to store in a cool and dry warehouse with a relative humidity not exceeding 75%.
Compatibility testing should be conducted when compounding with other raw materials. Although MY651 is compatible with most raw materials, it may react when compounded with certain strong oxidizing ingredients or acidic preservatives. You can observe changes in appearance, viscosity, and skin feel through small-scale testing to ensure stability before scaling up production.
As long as these precautions are followed and the formula and storage conditions are reasonably controlled, SMOICON ® The probability of stability issues with MY651 is low, and it can stably exert its performance advantages in cosmetic formulations.
