When choosing skincare products and makeup, we often seek a "smooth application" sensation or hope that the products can provide long-lasting moisturization and protection. Behind this quality experience, there is often a need for a type of highly efficient cosmetic raw material - organic silicon resins, such as IOTA 91003C.
IOTA 91003C is a colorless to slightly yellow transparent liquid, belonging to a highly cross-linked network structure of polyorganosiloxane. In cosmetic formulations, it plays multiple roles. Firstly, it is an excellent skin sensation regulator. Its molecular structure is smooth, which can greatly reduce the friction between the product and the skin, making foundation and lotion apply smoothly like silk, and not leaving a sticky "oil film" sensation after absorption.
Secondly, it is a powerful "water and color lock-up umbrella". IOTA 91003C can form a hydrophobic protective film on the skin surface, which not only reduces the evaporation of internal skin moisture and plays a role in auxiliary moisturization, but also acts like a shield to isolate external pollution. In makeup products, this layer of film can effectively prevent color powder migration and clumping, making the makeup last bright and shiny.
In the field of hair care, it also performs well. It can form a protective layer on the hair surface, fill in damaged hair scales, and reduce friction and breakage during combing, making the hair thicker and easier to style. Generally, the recommended addition amount in makeup formulations is 2-10%, while in hair care products it is 0.5-5%.
It should be noted that this type of organic silicon resin mixture needs to be stored in a sealed container. If exposed to the air for a long time, as the solvents evaporate, solid resin may precipitate out, but this does not affect its safety. Just re-dissolve it. Understanding these ingredients can help us select truly suitable beauty products for ourselves more scientifically.
