Phosphate Emulsifier improves stability and skin feeling
Sunscreen formulas do not simply increase the content of sunscreens, but find a balance between the oil phase, the aqueous phase, the emulsifier, and the auxiliary ingredients.A mature high-power sunscreen system needs to ensure that the sunscreen can be evenly dispersed, while avoiding problems such as stratification, oil analysis, and stickiness of the product.In this process, phosphate ester emulsifiers have become an important choice in the research and development of more and more sunscreen products due to their good emulsifying ability, formula adaptability and skin feeling performance.
Stability and skin feeling need to be improved at the same time
In the past, some high-power sunscreen products, in order to achieve higher protection, would increase the proportion of oil phase, sunscreens, and film-forming agents, but this can also easily cause some problems:
- A heavy feeling occurs during use
- Obvious oily film sensation after application
- stuffy skin experience after wearing it for a long time
- The stability of the formula decreases during storage
As an important part of connecting the oil phase and the aqueous phase, the emulsifier not only determines whether the product can form a stable emulsion structure, but also affects the product's spreadability, absorption and final skin feeling performance.For high-power sunscreen systems, an excellent emulsifying system needs to have good emulsifying stability, so that the components of the sunscreen phase can be evenly distributed, so as to help the product maintain consistency.
Help stabilize and upgrade the sunscreen system
Phosphate ester emulsifiers are a class of functional emulsified raw materials with special structural characteristics, and their molecular structure can help the oil phase and the aqueous phase form a more stable interface system.In high-power sunscreen formulas, the proportion of common oil-soluble sunscreens and emollient oils is high. If the emulsification system is insufficient, it will easily affect the stability of the product.
The phosphate emulsion system corresponding to PHSPTER ™922P is mainly composed of stearyl phosphate, c20-22 alkyl phosphate and behenic alcohol. Through the synergy between different structural components, it provides stable support for the emulsion system.Among them, stearyl phosphate and c20-22 alkyl phosphate belong to the phosphate structure, which can help improve the binding effect of the oil-water interface, while behenic alcohol, as a fatty alcohol component, can further optimize the architecture and make the product have a more stable texture while reducing the heavy feeling.
From stabilizing the emulsion structure to improving the consumer experience
Sunscreen products are used more frequently every day, so consumers are very sensitive to skin sensation.Modern sunscreen formulas not only need to solve the stability test in the laboratory, but also need to consider the actual use scenarios of consumers:
- Suitable for superimposed use after skin care in the morning
- Suitable for long-term wear in outdoor environments
- The compatibility between the product and the base makeup product
In this process, the emulsifier not only assumes the role of stabilizing the system, but also participates in the shaping of the skin texture of the final product.In some lightweight sunscreens, emulsifiers are needed to help form a smaller and more uniform droplet structure to make the product smoother.In highly moisturizing sunscreen products, the emulsifying system and Emollients need to work together to improve the comfort of the skin surface.
Phosphate emulsion system promotes the development of sunscreen formulas in the direction of high performance
A major feature of phosphate ester emulsifiers is that they can help form a more stable emulsifying structure, while providing a certain degree of optimization space in terms of skin touch.In the actual formula development process, R&D personnel usually match different types of emollients, thickeners, and auxiliary emulsifying ingredients according to product positioning.Some sunscreen lotions will combine structural adjustment ingredients such as Hydrogenated castor oil to improve system stability and keep the product in good condition during storage and transportation.
High-power sunscreen products usually need to add a certain proportion of oil-phase ingredients to enhance the dissolving ability and application experience of sunscreen.However, the oil ratio is too high and it is easy to cause greasy feeling, so it needs to be balanced by a reasonable emulsification system.As a common emollient, Isopropyl myristate can help improve product ductility, make sunscreen easier to spread on the surface of the skin, and reduce the heavy feeling caused by some oils.
From single protection to comprehensive care
Consumers hope that a product can not only provide UV protection, but also moisturize, improve skin feeling, and assist in base makeup.There are more and more sunscreen products that integrate the concept of skin care on the market, such as moisturizing sunscreen, skin-nourishing sunscreen, and pre-makeup sunscreen.This trend has also driven raw material suppliers to continuously optimize their product portfolios and provide brands with more complete formulation solutions.
In the moisturizing sunscreen system, the combination of Moisturizer and emulsifying system is particularly important.Moisturizing ingredients such as GLYCERETH 26 can help enhance the moisturizing feeling of the formula and reduce dryness after the product is used.For products that need to take into account sunscreen and makeup performance, the formula also needs to consider the compatibility with makeup products.
The combination of phosphate emulsifier and modern sunscreen system
Sunscreen products are developing in a more stable, efficient and comfortable direction.Especially in the field of high-power sunscreen, due to the increasing complexity of the system, the performance requirements for emulsifiers are also getting higher and higher.Traditional emulsifiers pay more attention to the basic emulsifying effect, while modern formulas need to consider some issues:
- Improve the dispersion uniformity of sunscreens
- Long-term storage stability
- Improve the skin feeling after the product is applied
- Improve compatibility with other skin care ingredients
Due to the structural characteristics of phosphate ester emulsifiers, they have shown good application value in these aspects.
Formulation refinement promotes raw material innovation
An excellent high-power sunscreen product needs to achieve a balance in many aspects: the first is the protective effect, which needs to ensure the stable functioning of the sunscreen system; the second is the use experience, which needs to be light, non-sticky, and easy to push away; and finally, the stability of the product, which needs to meet the storage and transportation requirements in different environments.
In addition to emulsifiers, the formula design will also combine different types of auxiliary raw materials.In some oil-in-water systems, R&D personnel will choose the appropriate oil in water emulsion according to product needs to help establish a more refreshing emulsion structure.For more moisturizing or special texture products, you may need to consider the water in oil emulsion system to meet the needs of different consumers for skin feeling and protection durability.
Stability, efficiency and comfort have become the core directions
In the future, with the continuous upgrading of sunscreen technology, more functional emulsifying systems, emollient systems and compound solutions will be used in personal care products.For raw material suppliers, continuous attention to market trends, optimizing product performance, and providing more flexible formulation support will become an important way to participate in the global personal care market competition.In the process of continuous upgrading of high-power sunscreen products, emulsifiers have gradually become an important factor affecting product quality from the basic raw materials behind the scenes.Through the reasonable selection of phosphate emulsion system and the optimization of different functional raw materials, the brand can create a new generation of sunscreen products that are more stable, safe and meet consumer needs.
