01 Introduction to Amino Silicone Oil
Amino silicone oil is a chemically modified organic silicon product that replaces some methyl groups to obtain polymers with different properties. Its properties make it an important ingredient in hair care products. In the hair care market, we often see amino silicone oil ingredients such as amino terminated polydimethylsiloxane and bis aminopropyl polydimethylsiloxane, which play an indispensable role in high-end hair care products and are highly favored by international salon brands.
Chemical properties and effects
The amino group (- NH2) in amino silicone oil molecules has significant polarity and can tightly connect with exposed protein groups (such as hydroxyl and carboxyl groups) in damaged hair through hydrogen bonding and electrostatic interactions, forming stable directional adsorption and high orientation. This strong and durable combination allows amino silicone oil to adhere to the surface of hair for a long time, effectively filling the damage of hair scales, thereby making hair smoother and more delicate, reducing frizz and splitting phenomena.
02 Function of Amino Silicone Oil
▣ Increase hair adhesion
Amino silicone oil is selectively adsorbed onto damaged hair through hydrogen bonding and electrostatic interactions, filling the hair cuticle damage and improving the smoothness and delicacy of hair.
▣ Improve hair smoothness
Due to the flexibility and hydrophobicity of amino silicone oil molecular chains, it can form a uniform thin film on the surface of hair. This film can effectively reduce friction between hair, thereby enhancing the smoothness of dry and wet combing and reducing damage to hair during combing. At the same time, it also gives the hair a softer and smoother touch, making the overall hair texture more delicate and smooth.
Enhance elasticity and gloss
When amino silicone oil penetrates deep into the hair, it can repair damaged hair and enhance hair elasticity. In addition, due to the high refractive index of amino silicone oil, which is about 1.45, it can effectively increase the glossiness of hair, giving it a healthier and brighter appearance.
▣ Protection and stability effects
The thin film formed by amino silicone oil on hair can effectively resist further damage to the hair from the outside world. At the same time, its excellent thermal stability ensures that its protective performance can still be maintained in high temperature environments, so that the use of hot tools such as hair dryers and curling irons will not damage its protective effect, making it very suitable for use in salon hair dyeing and care.
03 Factors affecting performance
Amino content and effect
Increasing the amino content enhances polarity and reactivity, and these amino silicone oils have demonstrated unique advantages in hair care, becoming key ingredients in many high-end hair care products. Generally speaking, the higher the amino content, the higher the ammonia value and softness, thereby providing better hair care effects.
▣ Product application examples
The performance of amino silicone oil is also affected by its amino content and distribution. Amino silicone oil with a certain ammonia value can be made into a transparent microemulsion, which can be combined with an appropriate anionic surfactant to create a transparent shampoo. Different types of amino silicone oil products, such as the Wanstone series, provide improved combing performance, gloss, and smoothness, suitable for various hair care needs.
04 Future Outlook
The possibilities brought by technological development
With the continuous advancement of technology, amino silicone oil has developed into an important chemical category and can effectively combine with hair to enhance its softness and washability. Its unique molecular structure and properties enable this type of product to effectively bind with hair, enhancing its softness and washability. Meanwhile, the diversity of amino silicone oil series products also brings more possibilities for their application in the field of hair care.
