The complexity of effective skin care formulas continues to increase, and ion and pH fluctuations often cause demulsification and stratification of the emulsifying system.As a classic oil-in-water Emulsifier, OILREE®MY925 CETEARETH- 25 relies on a fat-soluble molecular structure to achieve ion-resistant, acid-base-resistant emulsifying performance, and can produce a delicate-looking emulsion, which is widely used in creams, lotions, and gels. Skin care products.
Fat-soluble molecular structure, build a stable oil-water interface membrane
Fat solubility is a very critical attribute of OILREE®MY925. Under heating conditions, the raw material can be well dissolved into the oil solution.When the oil phase is dispersed into the aqueous phase system through homogeneous shear, the raw material molecules will be quickly arranged at the contact interface of the oil and water phases, forming a dense interfacial protective film, reducing the interfacial tension and inhibiting the collision and agglomeration of tiny oil droplets.
Compared with many ordinary emulsifiers on the market, its most prominent advantage is its anti-interference ability.When there are electrolytes in the formula system, or the pH fluctuates within a reasonable range, the emulsified film is not easy to be destroyed, and the finished product can maintain a complete emulsified state. As a common emollient component, Isopropyl myristate can be added in small quantities to improve the drag feeling when the cream is applied, and it cooperates with OILREE®MY925 to further optimize the skin feeling experience of the end product.
Different skin care dosage forms have different demands on the emulsifying system
- For cream products, it is necessary to carry a higher oil phase, and the cream body is dense and delicate, without graininess.；
- Moisturizing lotion products, pay attention to fluidity, the upper skin is light and easy to push away, to avoid heavy and stuffy skin；
- For gel products, while emulsifying, it is necessary to maintain a transparent appearance as much as possible.
OILREE®MY925 has a good adaptation effect on the above three types of dosage forms.In the formula of high-oil face cream, it can load a lot of oil, the cream is bright and delicate, and the risk of rubbing mud is reduced; when the emulsion is formulated with light oil, a refreshing and flowing texture can be obtained; in the emulsified gel system, with the corresponding thickening system, the problem of turbidity and whitishness of the system can be avoided.
Excellent formula compatibility, enabling stable mass production of products
OILREE®MY925 has good compatibility with most commonly used oils and polyol moisturizing materials in cosmetics.The oil-in-water emulsion constructed using OILREE®MY925, after multiple high and low temperature cycles, the overall emulsion structure can be kept intact, and the properties of the paste will not change significantly.
In the face of the system impact caused by the ionic composition, the advantages of this emulsifier will be more obvious.Many water-soluble active ingredients have their own ionic properties, which can easily penetrate the interfacial membrane formed by ordinary emulsifiers, causing stratification in the late stage of storage.The special molecular structure of OILREE®MY925 can weaken the negative effects of ionic substances and broaden the range of active raw materials available in the formula.At the same time, small fluctuations in the pH of the formula are not easy to directly cause the failure of the emulsifying system, giving greater fault tolerance for formula debugging.
GLYCERETH 26 can be added to the system as a moisturizing component to enhance the overall moisturizing feeling without causing excess sticky burden. Together with OILREE®MY925, it creates a skin care formula that takes into account stability and skin feeling.
High-quality skin feeling and convenient physical properties, taking into account terminal experience and industrial production
The emulsified body obtained by OILREE®MY925 emulsification has a small and uniform particle size of the internal oil droplets, and the texture is soft and delicate to the naked eye.Applied to the surface of the skin, it will not form a heavy and closed oil film, and the oil will spread evenly, taking into account the moisturizing ability and comfortable touch.Many oil-in-water systems are prone to rapid drying out after application. The rational use of OILREE®MY925, combined with a polyol moisturizing system, can slow down the loss of water and prolong the skin's moisturizing time.OILREE®MY925 has been verified by a large number of actual projects, and can be well adapted to the development of effective skin care formulas, providing emulsifying solutions for creams, lotions, and gels.
Diversified and complex application solutions to create a differentiated texture of skin care products
The characteristic of OILREE®MY925 is to achieve a balance between emulsification ability, system tolerance, and dosage form adaptability.In addition to being used as the main emulsifier alone, it can also be used in combination with other emulsified raw materials to further optimize skin feeling and achieve product differentiation.When carrying out complex design, we can learn from each other's strengths and complement each other's strengths. Under the premise of ensuring the stability of emulsification, the rheological properties of the paste can be adjusted to obtain a variety of finished products with different textures.Bis diglyceryl polyacyladipate 2 can be added to the formula as an emollient ester to improve the softness of the cream and relieve dryness. It is used with OILREE®MY925 to formulate moisturizing but non-greasy lotion products.
Lotion is mostly used for daily basic skin care, the formula pursues gentle and stable, and the skin feels fresh.The emulsion is formulated with OILREE®MY925, and the proportion of the oil phase can be flexibly adjusted. The low-oil version is light and suitable for spring and summer. After the oil phase is increased, the moisture content is improved, and it is suitable for the dry season.
The construction of a moisturizing system is also the focus of formula design. Polyols are a very common moisturizing raw material in skin care products, which can absorb moisture and improve dry skin.OILREE®MY925 is well adapted to conventional polyols such as glycerin and propylene glycol. Even if polymer moisturizing raw materials are added, it can still play a stable emulsifying role.OILREE®MY925 is a typical classic emulsified material, which is resistant to ions, acids and alkalis, and has a delicate paste after emulsification. It is compatible with many types of creams, lotions, and gels.
The dispersion state of the oil droplets directly determines the appearance of the paste. The smaller the particle size of the oil droplets, the more delicate the appearance of the paste.Only when the emulsifier is combined with the homogenization process can the oil phase be cut into tiny oil droplets.925 can quickly adsorb and wrap oil droplets at the oil-water interface, inhibiting the fusion of oil droplets.After the homogenization is completed, the fine oil droplets can remain dispersed for a long time, and the finished product is not easy to become rough after long-term storage.
Summary
As a classic oil-in-water emulsifier, OILREE®MY925's core advantages are concentrated in its excellent ion resistance, acid-base resistance and anti-interference ability. It can always build a stable and complete emulsifying structure in the formulation environment of complex active complex ligand systems and small acid-base fluctuations, creating a high-quality emulsion with uniform particle size and delicate texture.It can be used alone as the main emulsifier, or it can be combined with emollient and moisturizing raw materials to optimize the skin feeling of the product and create a differentiated skin care formula.
