The Carbopol family is vast, and the performance differences between different grades often determine the stability and user experience of the final product. Faced with common codes such as Carbopol 940, 980, 676, and ETD2020, formulators need to make choices based on the environment, ingredients, and expected texture of the product. Understanding the characteristics of each brand is the first step in precise selection.
Carbopol 940 and 980: representatives of classic transparent texture
The core advantage of Carbopol 940 is its ability to provide extremely high viscosity, while the resulting gel system is clear and transparent. For those products that regard the appearance transparency as an important selling point, if the frozen moisturizing gel, transparent skin care essence, Carbomer 940 is often the priority. It can fully swell and thicken under neutral to weak alkaline conditions, forming a solid and stable gel structure.
Carbopol 980 is highly similar in performance to 940, both pursuing high transparency and high viscosity performance, but it additionally adds environmental and safety advantages. Carbopol 980 has better biodegradability and can meet increasingly stringent environmental regulations. For developers who wish to continue the Carbopol 940 formula framework while also improving product environmental friendliness, Carbopol 980 is an ideal alternative. The two basically overlap in their scope of application, with the main difference being the latter's upgrade in the dimension of sustainability.
Carbopol 676 and ETD2020: Reliable choices in complex environments
Carbopol 676 is a brand known for its salt resistance, and many formulations contain electrolyte components such as surfactants, inorganic salts, or ionic substances in plant extracts. These components can disrupt the thickening network constructed by ordinary Carbopol, causing a sudden drop in viscosity or even thinning of the system. Carbopol 676, with its ion resistance, can maintain stable suspension ability and viscosity in complex systems with high salt and high surfactant content. This feature makes it particularly suitable for hair care products such as shampoo, conditioner, shower gel, and some sunscreens containing electrolytes.
ETD2020 focuses on the performance advantages of oxidation resistance and high pH resistance. In strongly alkaline environments or formulations containing strong oxidants, conventional carbomers may degrade and viscosity significantly decreases over time. ETD2020 can maintain chemical stability under such harsh conditions, and its thickening and suspension functions are not affected. This characteristic makes it the preferred rheological modifier for home cleaning agents, industrial cleaning agents, and formulations containing oxidizing ingredients. Meanwhile, ETD2020 is also suitable for personal care products that require high viscosity and transparency, but its unique value is more reflected in its reliability in extreme environments.
Selection logic from the perspective of brand differences
The differences among the four grades are mainly reflected in three dimensions: tolerance to electrolytes, stability to oxidation and high pH environments, and environmental compliance. If the product ingredients are simple, pursuing ultimate transparency and high viscosity, Carbopol 940 or 980 is a direct choice, depending on whether emphasis is placed on biodegradability; If the formula inevitably contains salts or ionic surfactants, the salt resistance of Carbopol 676 becomes crucial; If the product is in an alkaline or highly oxidizing system, the weather resistance of ETD2020 is indispensable.
