NSOAF™TMPI18 (INCI name Trimethylolpropane Triisostearate), as a synthetic ester raw material with balanced performance, has become a highly favored category in cosmetic raw materials due to its stable chemical structure and diversified application characteristics. It is widely integrated into skin care, makeup, lip care and other scenarios, bringing consumers a delicate and comfortable experience.
From the point of view of chemical nature, Trimethylolpropane Triisostearate is a typical polymer branched-chain ester, which is formed by the esterification reaction of trihydroxymethyl propane and isostearic acid to form a complete triester structure.This structure gives it unique molecular properties. The rich branched chain structure in the molecule gives it good fluidity. At the same time, the higher molecular weight ensures the moisturizing degree when used, and it will not be too light and thin, causing the skin to feel hollow.As an important member of
Cosmetic Emollients, its chemical properties are very stable, it is not easy to be oxidized, and it will not easily rancid or deteriorate. It can maintain a stable state for a long time in the formula. This is also the key reason why it can be adapted to a variety of complex formula systems.
Unlike the single effect of ordinary oils, the core functions of TMPI18 revolve around moisturizing and conditioning.Its most basic and core function is to nourish the skin as a softener. When applied to the surface of the skin, it can quickly form a thin and breathable protective film. This film will not close pores, but can effectively lock in the moisture on the surface of the skin, reduce the evaporation and loss of moisture, and quickly restore dry skin to a soft state.Many skin care products in autumn and winter will add such raw materials to relieve dry, rough, and peeling skin, and keep the skin delicate and smooth.
In the formulation system, it can also play a role in assisting emulsification and improving the stability of emulsions and creams.Cosmetics are mostly mixed systems of water and oil. It is difficult for water and oil to blend, and they are prone to stratification and demulsification. TMPI18 can be adapted to the oil phase system to help balance the interfacial tension of the formula and make the water and oil components blend more evenly. Even if stored for a long time, it can maintain a uniform texture and is not prone to oil-water separation, agglomeration and other phenomena.This stabilizing effect makes it an indispensable auxiliary raw material in many basic skin care formulas. When used with
Oil in water emulsifier, it can further optimize the emulsifying effect and make the product texture more delicate and smooth.
From the point of view of application scenarios, TMPI18 is highly adaptable, covering multiple categories such as skin care, makeup, and lip care, and it shows the advantages of differentiation in different products.In basic skin care products, it is a commonly used raw material for face creams, body creams, and hand creams. It is recommended to control the addition amount to 1%-5%, which can not only exert a moisturizing effect, but also will not make the product too heavy and sticky.When applying this kind of skin care products with this raw material added, the skin feels smooth and does not have the sticky feeling of ordinary oils. After absorption, the surface of the skin shows a natural soft state and is not oily. It is suitable for all skin types, even oily skin, it will not be burdensome.
Lip products are an important scene for TMPI18 to take advantage of its advantages. It can be seen in lip balm, lip glaze, lipstick and other products.The skin of the lips does not have sebaceous glands, and it is very easy to dry and peel. It needs gentle and long-lasting moisturizing raw materials. This raw material has a mild texture and is non-irritating. It can deeply nourish the lip skin, relieve dryness and cracking, and improve the gloss and ductility of the product.With the addition of its lip products, it is smooth and not stuck when applied, and can evenly cover the lip lines, giving the lips a full and shiny state. It can also reduce the heavy feeling caused by waxy raw materials and create a light and comfortable upper lip experience. This is also the reason why it has become the core raw material for lip care and makeup.
In makeup products, TMPI18 has more diverse functions. Liquid foundation, concealer, makeup primer and other products rely on it to enhance the use experience.Makeup contains a large amount of powder and toner, which is prone to agglomeration and uneven spreading. The raw material has good wetting and dispersing ability, can wrap the powder particles, and the toner is evenly dispersed in the formula to avoid powder stuck and mottled, so that the base makeup is more obedient and natural.At the same time, it can improve the ductility of the product, make liquid foundation and concealer easily push away, and reduce the drag when applying. With silicone oil raw materials, it can further optimize the freshness and create a light and obedient long-lasting makeup look.
In addition to a wide range of application scenarios, the advantages and characteristics of TMPI18 are very prominent, which is also the key to its standing out among many ester raw materials.The first is that the skin feeling experience is superior. It takes into account the moisturizing and refreshing feeling. It is different from the heavy and stuffy skin of mineral oils, and it is also different from the thin and non-feeling of lightweight esters. After application, it presents a silky and soft high-grade skin feeling, fast absorption, non-stick clothing, non-stuffy pores, whether it is skin care products or makeup, it can enhance the overall experience of use.
The second is the dual advantages of stability and compatibility. It has a stable chemical structure, oxidation resistance and low temperature resistance. It can maintain stable properties at different temperatures and environments, and will not affect product quality due to environmental changes.At the same time, it can be compatible with a variety of cosmetic raw materials, whether it is silicone oils, oils, emulsifiers, moisturizers, etc., it can be well adapted, there will be no contraindications to compatibility, and it can be flexibly matched to create products with different effects and textures.
Moreover, it is gentle and safe, suitable for a variety of skin types. As a raw material for synthetic esters, it does not contain sensitizing impurities, is mild in nature, and does not irritate the skin. After strict quality testing, the acid value, iodine value and other indicators are in line with the standards of cosmetic raw materials. Under normal use, it will not cause skin sensitivity, redness and other problems.Whether it is healthy skin, fragile sensitive skin, or lip skin, it can be used with peace of mind, which has further expanded its scope of application and become an optional raw material for maternal and child care and sensitive skin products.
In addition, its ease of use is also worth mentioning. It can be stored at room temperature, away from light and airtight, without special storage conditions. The packaging specifications of 20KG/barrel are suitable for bulk use by cosmetic manufacturers.
In the actual formulation application, the value of TMPI18 is also reflected in the optimization of details.In moisturizing products, it can work synergistically with
Moisturizing Agent to strengthen the water-locking effect, extend the moisturizing time, and keep the skin hydrated for a long time.In makeup products, it can enhance the adhesion of the powder, make the makeup longer lasting, while increasing the luster of the product, and create a natural and translucent makeup effect.In the emulsifying system, it can assist in stabilizing the formula, reduce the amount of emulsifiers, make the product composition more streamlined, and reduce the burden on the skin.
Taken together, TMPI18 is a highly practical cosmetic raw material. Based on a stable triester structure, it has multiple effects such as softening, emulsifying, dispersing, and locking water. It covers skin care, makeup, lip care and other diverse scenarios. With superior skin feeling, good stability, gentleness and safety, it has become a high-quality choice among
Emollients.It has no complex usage restrictions and can be flexibly adapted to various formulation systems. It can not only improve the product experience, but also ensure stable product quality and meet the dual needs of cosmetic manufacturers and consumers.
In the selection of cosmetic raw materials, high-quality basic raw materials often determine the core quality of the product. NSOAF™TMPI18 (Trimethylolpropane Trisostearate) has no fancy concept, but with solid performance and stable performance, it has become an indispensable part of the beauty and skin care formula.It uses a simple and direct way to provide soft care for the skin, give stable quality to the product, and interpret the core values of basic cosmetic raw materials.
