Among body care products, massage ointment has always been a more special category.It looks closer to ordinary skin care creams, and it also requires an aqueous phase, an oily phase, an emulsifying system, and a thickening structure, but when it is really used, there is a clear difference between the two.Ordinary face creams usually pay more attention to the absorption speed, moisturizing feeling and softness of the skin surface after application, while massage creams need to face a longer pushing and kneading process.
The product cannot dry out quickly as soon as it is wiped off, nor can it maintain a very heavy oily film all the time.During the massage process, there needs to be enough room for sliding, and the cream should not be too sticky because of the high proportion of oil.At the same time, the product also needs to maintain a certain consistency, otherwise it will easily appear too thin when used and massaged.
Mingya launched a massage cream formula. The formula uses water, glycerin and Hanshen gum to establish the basic aqueous phase. At the same time, a higher proportion of 26# white oil is used as the main oil phase, and it is combined with products such as OILREE®MY967, OILREE®MY916, OILREE®MY749-B and THICION®MY905 to complete the adjustment of emulsification, structure and skin feeling.
The meaning of emulsifiers is not just to mix water and oil together
In the formulation discussions of many cream products, emulsifiers are often simply understood as materials that connect water and oil. On the one hand, the product needs to stably disperse a large amount of oil phase in the aqueous phase system; on the other hand, the formed emulsified structure must also be able to withstand the heating, homogenization, and subsequent transportation and storage in the production process.
OILREE®MY967 PEG-100 STEARATE/GLYCERYL STEARATE in this formula is an oil-in-water Emulsifier with slightly yellow particles. It is generally used in the preparation of oil-in-water creams and emulsions. It is a non-polar oil phase emulsifier and stabilizer. It can also be used alone to obtain a good emulsifying effect and has certain stable properties.
45% of the white oil constitutes a relatively large oil phase load, and emulsifiers need to help these oil phase materials form a stable emulsifying system.Whether the final product can maintain a uniform, delicate and suitable paste state is largely related to the emulsification system.After different oils and fats and different structural raw materials enter the system, the overall emulsifying environment will be changed.For such systems, the choice of oil in water emulsion needs to be judged in the entire oil-water structure, not just the raw material itself.
OILREE®MY916 enters the massage cream and assumes more than just a thickening effect
In this formula, the amount of OILREE®MY916 CETYL PALMITATE added is 2%.It is a skin sensation regulator with white particles. It is described in the product information as having good emollient properties and can be used in skin care and other products.In creams, it can help stabilize and thicken the system, and can assist in emulsification.
What OILREE®MY916 provides here is not simply hardness, but participation in the establishment of the entire oil phase structure.It also has the characteristics of emollient skin, which can increase the architecture while adjusting the final skin feeling to a certain extent.Using it in creams can replace some 1618 alcohol, thereby reducing the whiteness of application and improving the texture of the product.
OILREE®MY749-B let the oil phase be more than just the oil phase
If white oil is responsible for providing a more basic sense of lubrication during massage, then OILREE®MY749-B BIS-DIGLYCERYL POLYACYLADIPATE-2 is more inclined to oil phase structure and skin texture adjustment.It can be miscible with a variety of oils and paraffins, and it can also be compatible with viscosity modifiers such as cetyl alcohol, stearic acid, beeswax, mineral lipids, and triglycerides.Because the oil phase of massage ointment is usually not composed of one kind of oil.There will be differences in the viscosity, polarity, melting point and skin feel of different oils and fats.If the compatibility relationship between them is not handled well, the product may have unstable structure, oil phase precipitation, or skin sensation changes.
The viscosity performance of OILREE®MY749-B is close to that of natural lanolin within a certain temperature range, but its viscosity will not change to the same extent due to temperature, light and time, and it has good color stability.
The addition of complex polymers has brought the problem to the skin-feeling level.
In addition to the oil phase raw materials, THICION®MY905 ACRYLAMIDE & Ammonium acrylate copolymer &MINERAL OIL & LAURETH-7 in the C phase is also worth paying attention to.It can be used as a Moisturizer and lubricant to provide a refreshing, silky and delicate skin feeling while reducing the stickiness of the system.
For massage creams, the addition of such materials in the later stage can also be used as a further modification of the final consistency and skin feeling.Because after the emulsification system is established, the product already has an infrastructure, and then fine-tuning the skin feeling at this time is usually easier to control than adding all functional materials together at the beginning.
The high-level sense of massage cream often comes from these details
In the past, it might just be concerned about moisturizing or not, but now it will also be concerned about the speed of pushing away, the degree of greasy, whether it is white, whether there is a sense of pulling, whether it is easy to clean up after massage, and the touch of the skin after use.
But every structural raw material in the formula table may have a relationship with these experiences.For example, OILREE®MY916 can affect the cream structure and emollient feeling; OILREE®MY749-B can improve the softness and adhesion of the oil phase; OILREE®MY967 helps establish a stable emulsified structure; THICION®MY905 further adjusts the skin feeling.Looking at it separately, each raw material seems to be very ordinary, but putting them in the same system will produce different recipe logic.
Conclusion
Judging from a specific massage cream formula, the high oil phase does not mean simply increasing oil, and the emulsifier is not just responsible for mixing water and oil.It is a kind of formula synergy that exists between various products.
White oil provides the main oil phase foundation, structural raw materials help to establish the paste, the emulsifying system is responsible for connecting the two phases of water and oil, and the polymer system added in the later stage further adjusts the consistency and skin feel of the product.At the same time, the basic aqueous phase composed of water, glycerin and Hansoh gum also keeps the product in the form of an emulsified cream rather than a simple ointment.
