If you’re a manufacturer, formulator or procurement manager working with personal care, homecare or cleaning products, you’ll know that your ingredient choices are under more scrutiny than ever. Your retail customers are asking questions. Your end consumers are reading labels. And regulators across multiple markets are taking a closer look at the synthetic chemistry that’s been standard practice for decades.
For many manufacturers, the shift towards natural surfactants is becoming a sound technical and commercial decision. Two ingredients sitting at the centre of that shift are Cocamidopropyl Betaine (CAPB) and Alkyl Polyglucosides (APGs). If you’re not already working with them, it’s worth understanding what they offer and why so many manufacturers are making them a core part of their formulations.
What are natural surfactants?
Surfactants, short for surface-active agents, are the workhorses of most cleansing, foaming and emulsifying formulations. They reduce the surface tension between substances, allowing oil and water to mix, dirt to be lifted away, and foam to form. Without them, your shampoo wouldn’t lather, your hand soap wouldn’t cleanse, and your cleaning fluid wouldn’t cut through grease.
Conventional surfactants have traditionally been derived from petrochemicals. Natural surfactants, by contrast, are produced from plant-derived raw materials like coconut oil, corn sugars and fatty alcohols from vegetable sources. They’re generally biodegradable, and many are compatible with recognised natural and organic certification schemes.
It’s worth being clear that natural doesn’t mean unprocessed. Both CAPB and APGs go through manufacturing processes to get from raw material to functional ingredient. What sets them apart is their origin and environmental profile, not that they are less complex than their synthetic counterparts.
What is Cocamidopropyl Betaine?
CAPB is derived from coconut oil and belongs to the amphoteric surfactant class. This means its charge behaviour changes depending on the pH of your formulation. It can act as either anionic or cationic, which gives it a versatility that’s useful in many formulations.
Its mildness is probably its most commercially significant attribute. CAPB has a well-established skin compatibility profile, which is why you’ll find it across some of the most sensitive product categories, such as facial cleansers, baby shampoos, hand soaps and toothpaste, as well as mainstream shampoos and body washes. It produces stable, creamy foam and works well as a secondary surfactant alongside the primary anionic surfactants like Sodium Lauryl Sulphate or, increasingly, in sulphate-free products where mildness is a priority.
CAPB is also a good viscosity modifier, which can reduce your reliance on additional thickeners.
However, the quality of CAPB can vary depending on the manufacturing process. Poorly processed material can contain elevated levels of DMAPA, which can aggravate sensitive skin. So, choosing the right supplier that can provide CAPB to a consistent specification is essential. It’s not an ingredient you can cut corners on when sourcing it.
What are APGs?
APGs are non-ionic surfactants produced by combining glucose (typically derived from corn starch)Â with fatty alcohols sourced from coconut oil or palm oil. The result is a surfactant with an excellent environmental profile and a mildness that makes it well-suited to some of the most demanding formulations.
APGs perform well in hard water. Many surfactants don’t foam as efficiently in water with higher mineral concentrations. APGs maintain good lather across a wider range of conditions, which matters if your products are being used across different geographies. They’re also compatible with a broad range of other surfactants, including other mild or natural options, so they integrate well into complex formulations.
APGs are well-suited to many shampoos and body washes, facial cleansers and baby products. They’re increasingly the surfactant of choice in the growing market for eco-friendly household and industrial/institutional cleaning products. They’re biodegradable, derived from renewable feedstocks and are recognised by most major natural certification bodies, which makes them an excellent fit for products that are positioned with environmental or natural credentials.
From an on-pack perspective, APGs are one of those ingredients that consumers and buyers tend to view positively when they see them listed. That’s not always true of many surfactants, so it’s worth noting.
Why more manufacturers are making the switch
The reasons for moving towards natural surfactants like CAPB and APGs are rarely down to a single factor. More often, it’s a combination of commercial, regulatory and formulation pressures converging at the same time.
Retail buyers are increasingly asking their suppliers to justify their ingredient choices, particularly in categories like personal care and household cleaning. Having natural surfactants in your formulation, with the traceability and certification to back it up, gives you a much stronger position in those conversations.
On the regulatory side, some conventional surfactants attract greater scrutiny in the EU and other markets. Manufacturers that wait for legislation to force a reformulation tend to find themselves under time pressure and with fewer options. Getting ahead of that by working with biodegradable, plant-derived alternatives is a more comfortable position to be in.
From a formulation standpoint, CAPB and APGs are both well-suited to mild, sulphate-free applications where most new product development energy is focused right now. They’re proven, well-characterised ingredients with solid toxicological and regulatory dossiers, which makes your internal sign-off process more straightforward.
Biodegradability is another key factor that’s moving up the agenda, particularly for rinse-off products. As wastewater regulations continue to tighten, the environmental profile of the surfactants you use matters in ways that didn’t a decade ago.
Finally, if achieving certifications like COSMOS is relevant to your market positioning, natural surfactants make that path more accessible. These certifications are becoming a meaningful commercial differentiator in several product categories, so building your formulation around compliant ingredients from the outset is far easier than trying to reformulate later.
What to look for when sourcing natural surfactants
Sourcing natural surfactants requires a bit more due diligence than finding a supplier with the right product code. Feedstock traceability is a consideration, particularly for palm-derived ingredients, where supply chain transparency is expected by retailers and certification bodies alike.
You’ll also want to know where your raw materials are coming from and whether your supplier can demonstrate responsible sourcing.
Consistent purity matters, too. As the CAPB example we mentioned earlier illustrates, process-related impurities can create real problems downstream. So, it’s worth working with a supplier who can provide robust quality documentation and maintain specification consistency across batches.
Regulatory support is another area where the right supply partner can add real value.
Natural ingredients don’t exist outside the regulatory framework. They still need to be properly documented for REACH, safety data sheets need to be accurate and up to date, and any market-specific requirements need to be understood.
At MegaChem UK, we supply both CAPB and APGs and work closely with customers to understand their formulation requirements, quality standards and compliance needs.
So, if you’re evaluating your surfactant strategy or looking to make a switch, we’re happy to have that conversation. We can help you find the right ingredient, at the right specification, backed by the supply chain assurance your business needs. Get in touch to learn more.
