DOWSIL™ 2-8566 Amino Fluid, formerly known as DOW CORNING 2-8566, is an innovative, high-performance silicone-based ingredient supplied by Dow Inc., specifically designed to revolutionize hair care formulations .
It is an aminofunctional polydimethylsiloxane, with the INCI name Amodimethicone. This chemical structure, featuring primary amine groups, gives it an "organic-like" nature that has a strong affinity for hair, allowing it to deposit onto the hair shaft and provide long-lasting benefits .
The primary function of DOWSIL™ 2-8566 is as a superior conditioning agent for hair. It is designed to impart a range of benefits that enhance both the look and feel of hair. It provides exceptional smoothness and significantly improves combing in both wet and dry states, making hair easier to manage and less prone to breakage during styling. It also enhances hair's natural shine, reduces unsightly flyaways, and helps maintain hair color vibrancy. Additionally, it offers heat protection, safeguarding hair from damage caused by styling tools like hair dryers and straighteners .
This amino fluid is incredibly versatile and is recommended for use in a wide variety of hair care products. It enables the formulation of clear conditioning shampoos, rinse-off and leave-on conditioners, styling aids, and treatments for chemically processed hair, such as colorants, perms, and relaxers .
It is particularly valued for its broad compatibility with other cosmetic ingredients, allowing formulators to create clear, stable products. It is also effective in cold process manufacturing, which can be more energy-efficient . DOWSIL™ 2-8566 is formulated to be vegan-friendly and non-GMO, aligning with consumer demands for ethical and sustainable products. It is a liquid with a characteristic fish-like odor, a boiling point of 150°C, and is not intended for medical, pharmaceutical, or food use
Specific Applications and Benefits:
Clear Conditioning Shampoos: Its unique chemistry allows it to be formulated into completely transparent shampoos without the need for emulsifiers. It provides a conditioning benefit "from the inside out," depositing onto the hair as the cleansers wash away.
Leave-in Treatments and Serums: It is ideal for leave-on products designed for frizz control and heat protection. The film it forms on the hair is hydrophobic, helping to block humidity (a major cause of frizz) while also providing a barrier against the high heat of styling tools. It significantly improves wet and dry combing without weighing hair down.
Color Protection: The cationic film helps to seal the hair cuticle, which can lock in color molecules and prevent them from being washed out. This helps maintain color vibrancy and longevity between salon visits.
Styling Aids: In mousses, gels, and creams, it provides flexible hold and adds shine. Unlike some polymers that can leave hair stiff or flaky, DOWSIL™ 2-8566 leaves hair feeling soft, naturally moving, and full of luster.
Chemically Processed Hair Treatments: It is particularly beneficial in products for permed, relaxed, or highlighted hair. It helps to repair the cuticle damage caused by these harsh processes, restoring smoothness and manageability.
