The copolymerization reaction of acrylamide and acrylic acid is an important polymerization reaction, through which polymers with specific properties can be synthesized. During the reaction, these two molecules combine to form copolymers with different chemical structures and properties. And cross-linking reaction, in simple terms, is the process of forming covalent bonds between polymer chains or within molecules, turning them into a network structure. The copolymerization crosslinking reaction of acrylamide and acrylic acid is generally formed by adding crosslinking agents or controlling polymerization under specific conditions to form this network structure.
THICION ® MY905, a highly efficient water-based thickener with acrylamide and
Ammonium acrylate copolymer as its core, is changing the selection criteria for beauty formulas through innovative design, especially in scenarios where both
Thickening suspension stability and skin feel optimization need to be done well. Its performance is outstanding.
Firstly: Efficient thickening
THICION ® MY905（ACRYLAMIDE and AMMONIUM ACRYLATE COPOLYMER and MINERAL OIL and LAURETH-7） It is an efficient water-based thickener in the cosmetics industry, with core ingredients including acrylamide and ammonium acrylate copolymer, 30% cosmetic grade mineral oil, and 7%
Laureth 7. It is a milky white viscous liquid with an active ingredient content of up to 60%. It is packaged in 50 kg drums and recommended to be added in an amount between 0.5% and 2%. As a raw material meeting the Grade 1-2 green standard, it is environmentally friendly and odorless, and the paste produced has a bright appearance. The biggest advantage is that it will not scale and rub mud after being applied dry, and it is also very resistant to biological hydrolysis. Its performance of water resistance, alkali resistance, and scrub resistance is also very good, which fully meets the requirements of today's beauty products for high-quality raw materials. It is also compatible with amino silicone oil lotion and other raw materials.
Secondly: molecular structure
THICION ® The key to MY905 lies in its clever molecular structure design and the coordination between its various components. From a chemical perspective, the copolymer of acrylamide and ammonium acrylate forms viscosity in the aqueous phase through its electrolyte sensitive network structure. The amine salt groups in the copolymer provide a stable aqueous environment and suitable viscoelasticity for the system. As a hydrophobic component, 30% cosmetic grade mineral oil is well matched with laureth 7. On the one hand, it makes the cream feel more smooth, and on the other hand, it effectively reduces scaling (solid deposition) after drying. In addition, the high active ingredient content of 60% ensures that adding a little bit can achieve the desired viscosity, greatly reducing the impact on the efficacy of other active ingredients in the formula and leaving more room for innovation for formulators. Even when used together with
Cationic Softener functional ingredients, the system can maintain stability and balance.
Thirdly: Differentiation advantage
In order to make the formulator's selection clearer, we have included THICION ® MY905 is compared with the three common thickening agents on the market:
(1) Carbomer: a little can achieve high consistency and make clear gel, but it is particularly sensitive to electrolytes and must be neutralized. Moreover, the Carbomer system is usually gel like texture, not smooth skin feeling, and it is easy to feel tight after drying. MY905 will take advantage of skin feeling.
(2) Polyacrylate or polymer thickeners: These thickeners have good transparency and stability, but are generally not as good as MY905 mineral oil composite systems in terms of lubricity and skin smoothness.
(3) Natural polysaccharides: meet everyone's preference for natural ingredients, but have weaker resistance to shear and microbial degradation, requiring additional preservatives. Moreover, in formulas with high oil content, synthetic polymers like MY905 are more stable.
This comparison shows that, THICION ® The uniqueness of MY905 lies in its integrated design.
Fourthly: Application scenarios
With its excellent comprehensive performance, THICION ® MY905 has broad application prospects in the field of beauty, and the following are three typical formula scenarios:
(1) Daily Moisturizing Cream: In this type of product, MY905 can effectively reduce the stickiness of the system, while significantly improving the scrubbing stability, suitable for formula improvement needs that enhance skin texture. This allows the moisturizing cream to provide long-lasting nourishment while keeping the skin fresh and non sticky.
(2) Functional repair cream (containing high levels of lipophilic activity): Its mineral oil phase has strong solubility, which can better carry lipophilic active ingredients, while the copolymer skeleton ensures the stable consistency of the formula. When using, it is recommended to use chelating agents and appropriate anti-corrosion strategies to ensure the safety and shelf life of the product.
(3) Hair styling lotion: In the scene of hair styling and gloss enhancement, the film-forming and smooth characteristics of MY905 can effectively reduce surface friction of hair, making hairstyles more durable and hair smoother.
In addition: Production compliance
In production and supply practice, there are several precautions to pay attention to for MY905: dissolution and dispersion. Although it is a water-soluble system, due to its mineral oil content, it is recommended to slowly add water phase in the premixed oil phase or under low shear conditions. Controlling the shear rate can effectively avoid the generation of bubbles. In terms of microbial protection, the high proportion of organic phase and mineral oil requires formulators to pay attention to the anti-corrosion system and it is recommended to conduct tests. During storage and transportation, it is necessary to store in a sealed environment at room temperature and avoid prolonged exposure to high temperatures to prevent changes in viscosity.
In terms of compliance, as a copolymer containing acrylamide monomer segments, the production batch of MY905 will undergo strict testing to ensure compliance with cosmetic regulations. For brands pursuing natural and clean labels, alternative sample solutions based on vegetable oils can also be provided to help customers make flexible decisions.
In summary
THICION ® MY905, with its unique technological advantages, not only meets the basic needs of product thickening and stability, but also precisely addresses the core demands of consumers. Intention to request THICION ® MY905 sample, please initiate an inquiry. We can provide relevant formula files to help customers verify the improvement effect of the product in a short period of time, and jointly open a new chapter in beauty formula.
