1. Application solution of acid and alkali system
(1) Introduction to the acidity and alkalinity of nugum products:
It can be clearly seen from the above table that nugums have acid, neutral and alkaline products. For the corresponding pH formula, it can be used directly without adjusting the pH, avoiding the introduction of additional acid and alkali regulating reagents, thus increasing the formula process.
(2) Product pH application range
The range of pH normally used by nugums is pH 2 to pH 13. They include AHA (acid) emulsion, antiperspirant, oral analgesics, chlorine bleach cleaner, alkaline ion cleaner, etc. It is particularly effective at some levels at extreme pH.
The company can provide aluminum magnesium silicate products that meet the application requirements of acid-base system according to the needs of customers.
2. Stability Solutions
(1) Stability performance introduction
NuGum can stabilize oil in water (O/W) emulsion in less dosage. The colloidal structure formed after clay dispersion can effectively maintain the state of surrounding and separating the dispersed phases.
A small amount of addition (typical addition of 1-2%) can stabilize emulsion containing anionic or non-ionic surfactants, a variety of oils, fats and waxes.
In addition, nugum's colloidal structure provides superior suspension of fine particles in an aqueous system. Its high yield value makes minerals, salts and organics, which are of high density, also suspend successfully.
Nugum products have many advantages as suspending agents, which can play a role in the formula:
|Prevent the collection of suspended solids from hardening.
|Control the phenomenon of water separation to make the concentrated suspension easy to redistribute.
|Ensure product consistency: pharmaceutical suspension, pesticide concentrate, etc.
|Obtain maximum suspension without loss of tipping.
|It will not form gel like irreversible gel like many organic adhesives.
|At the same viscosity, it can provide better suspension efficiency than organic glue, especially in low viscosity system.
(2) Introduction to compatibility function
Nugums are often used with organic thickeners to give their best performance. Clays help to coordinate viscosity and provide yield values, while organic gels and polymers improve the stability of clays in the presence of electrolytes, surfactants and other water-soluble substances, thereby protecting the colloids. Nugums and organic thickeners, for example, can be mixed with polyacrylic acid, cellulose and natural rubber in the range of 10:1-1:1.
As anionic clays, nugums are compatible with most anionic and nonionic surfactants, but not with most cationic surfactants. Their dispersions can be mixed with water-soluble solvents: up to 20% ethanol, 50% glycerin and 30% propylene glycol and polyethylene glycol.
The company can provide professional stability solutions according to the needs of customers to solve the problem of water separation and stratification of products.
3. Performance optimization scheme
Nugum brings good spreading and elegant cosmetics to relevant products. Because of its water insoluble and thin application characteristics, it is often used to prepare skin feeling non stick products. It can also be used to reduce or eliminate the sticky, colloidal or hanging threads of organic thickeners, making the products more delicate, beautiful and stable, and improving the performance of products, such as improving the skin feeling, wetting and gloss of make-up, so that thick cream can be smeared fluently; cleaner spray is easier, evenly applied and attached to the vertical surface; suspensions. Pump and dump freely without losing stability.
The company can provide professional solutions to improve the performance of the formula according to the needs of customers.
