Is Polyacrylamide Toxic?
You may be familiar with the term “Carbomer”, which is an ingredient in cosmetics and personal care products. What is it exactly?
Carbomer belongs to a group of high-molecular synthetic polymers. It is usually available as a white powder and is used primarily for stabilization, thickening and rheology. Due to its hydrogel properties, it is used widely in cosmetics and pharmaceutical products as well as industrial fields. Carbomer, or “binder”, is a component of the formula that gives the product a silky feel and smooth texture.
Carbomer is available in two common products: Carbomer and Carbomer. Although they share a similar name, their performance and usage are different. Do you want to know what the differences are between these two products? You won’t be disappointed, as the content below will explain it in detail.

The Core Difference Between Carbomer 940 and 980
While both Carbomer 940 and 980 are very popular types of carbomers, they do have some key differences between them. Below, we take a closer look at the differences in a few areas:
1. Viscosity performance
Carbomer940: This high-viscosity carbomer is ideal for formulas requiring thick textures such as creams and gels.
Carbomer980: It has a thickening effect, but it is also suitable for formulas that are transparent and light, such as skin care products.
2. Transparency
Transparency should be considered when choosing carbomers.
Carbomer940: The gel produced is typically slightly turbid and focuses more on the texture than visual effects.
Carbomer980: Its superior transparency makes it ideal for formulas that require crystal clarity, like clear gels and high-end skin products.
3. Stability and use scenarios
Carbomer: 940 is suitable for products with high textures and stability, like sunscreens or medical gels.
Carbomer: 980 is more flexible and suitable for low-concentration formulations.
4. Emulsification properties and rheological properties
Carbomer: 940 has a good emulsification capability and can combine better with oily raw material.
Carbomer: 980 has excellent rheological characteristics and can offer a more delicate experience when applying the formula.
√:Carbomer 940 and 980 each have their own advantages, and the key lies in your formulation needs. If your goal is high viscosity and high stability, 940 may be more suitable; if you pursue a transparent and refreshing texture, 980 would be a good choice.
Why Choose Carbomer 940?
1. Create the perfect texture to your cosmetics
Carbomer 940 can be a “unsung” hero in many cosmetic formulas. This powerful thickener also helps improve the spreadability of the product.
Carbomer is a great way to create gel products such as aloe gel, soothing gel and other gels. It is perfect for skin care formulas.
Creams, lotions and other products: This product can be used to thicken and stabilize creams and lotions. It ensures that the formula does not stratify and is of a smooth consistency.
Care Products: 940 improves the rheology, and smoothness in facial cleansers and conditioners.
2. Pharmaceutical industry: high-efficiency pharmaceutical excipients
Carbomer, due to its biocompatibility, is widely used in medical products and medications.
Topical Gels, such as anti-inflammatory and analgesic gels, can enhance the effectiveness of a drug and ensure that it is distributed evenly.
Ophthalmic Products :940 can be used to create artificial tears, eye gels and other products. The high stability of the product makes it safe.
3. Industrial Field: A powerful aid in stabilization and thicknessening
Carbomer is also an effective material for industrial applications.
Adhesives and Coatings: 940 can be used to improve the properties of coatings and products.
Improves consistency and adhesion of home care products such as floor cleaners, dishwashing liquids, and other household cleaning products.
How to Use Carbomer Correctly?
1. Dissolution or dispersion
It is important to use the carbomer in the formulation.
Predispersion: Sprinkle carbomer powder gradually into the water phase while stirring continuously to ensure even distribution.
A high-speed mixer will improve the dispersion of powders and prevent agglomeration.
2. Neutralization reaction
Neutralization of the carbomer is necessary to activate its thickening effect.
Neutralizer selection. Neutralizer selection.
Control pH. The carbomer’s thickening effects are best achieved between pH 5.0 and 10.0. A pH that is too high or low will affect the effect.
3. Dosage control
The carbomer content in a product will influence its texture and rheology.
Carbomer940 – the amount to use varies between 0.2% and 1.0%, depending on the consistency of the formula.
Carbomer980- the most common amount is 0.1% to 0.5%. This is best for products with a light texture.
The best way to find the ideal ratio is to adjust the dosage slowly according to the formula.
4. Combination
In order to optimize the performance of products, carbomer can be combined with other components.
Solubilizers are a way to improve the stability of a formulation.
Combining the product with moisturizing agents, such as sodium-hyaluronate or glycerin can improve the moisturizing effect and experience.
5. Avoid incompatible ingredients
Some ingredients are not compatible with carbomer. For example, high concentrations of electrolytes can destroy its thickening property. When formulating the formula, it is important to pay special attention to this issue.
♣Tips: Master the art of balance
The use of carbomer is an “art of balance”. You need to consider its thickening effect, transparency requirements, and the interaction with other ingredients in the formula. Only by mastering these details can you give full play to the advantages of carbomer and bring the best performance to the product.
How to Choose the Right Type of Carbomer?
1. Select according on the required viscosity
Because of its high viscosity, carbomer 940 works well in goods that need to have thick textures, like lotions, creams, and anti-inflammatory gels.
Carbomer 980: This substance has a somewhat lower viscosity but a higher transparency, making it ideal for compositions like gels, serums, and lubricants that call for light textures.
2. Choose according to appearance effects
Transparent products: If a crystal clear appearance is required, such as hyaluronic acid gel or transparent lubricating gel, Carbomer 980 is more advantageous.
Milky or opaque products: For example, moisturizing lotions or creams, Carbomer 940 is more suitable for giving the formula a thick and stable texture.
3. Choose according to the applicable field
Both can be used in the cosmetics industry, but the type that is used depends on the texture of the product and the preferences of the target consumer.
Medical field: Carbomer 980 is effective with transparent drug matrices, while Carbomer 940 is more suited for topical gels and anti-inflammatory ointments due to its stability and viscosity.
In the industrial sector, carbomer 940 is frequently utilized for products that have potent thickening properties, whilst 980 is better suited for coating or cleaning products.
4. Cost and formulation design
Carbomer 940 is a cost-effective and effective option if your formulation prioritizes viscosity and stability over excellent transparency.
The purchase of Carbomer 980 is more beneficial if the formulation calls for a high level of visual appeal (clear gel, for example).
♣How to make decisions quickly?
The key to choosing the type of Carbomer is to clarify the target characteristics of the product.
High viscosity + stability: choose Carbomer 940.
High transparency + light texture: choose Carbomer 980.
