Lauramidopropyl Betaine
A mild, foam-boosting surfactant for personal care and I&I cleaning products.
What is Lauramidopropyl Betaine?
Lauramidopropyl Betaine (LAPB) is an amphoteric surfactant derived from Lauric Acid, usually sourced from coconut or palm kernel oil, and the amino acid derivative Amidopropyl Dimethylamine. It carries both positive and negative charges depending on its pH, which gives it excellent compatibility across a wide range of formulations. You’ll find it classified as an amphoteric surfactant, sitting alongside Cocamidopropyl Betaine (CAPB) in the betaine family, though with a slightly different fatty acid chain that gives it its own distinct performance profile.
What is Lauramidopropyl Betaine used for?
LAPB earns its place in personal care formulations that need both mildness and foam quality. You’ll find it in shampoos and body washes, where it works alongside anionic surfactants like Sodium Laureth Sulphate (SLS) to boost foam volume and improve the texture of the lather. It’s also well suited to facial cleansers and baby care products, where its low irritation potential is particularly valued.
Beyond personal care, LAPB has a strong track record in institutional and industrial cleaning applications. Its compatibility with both anionic and cationic actives makes it a reliable co-surfactant in hard surface cleaners and disinfectant formulations, where you need consistent performance across various water hardness and pH levels.
Key benefits: LAPB
Broad pH
LAPB performs reliably across a wide pH range, which gives you real flexibility during formulation. You’re not constrained to a narrow window, and you won’t see a significant performance drop-off in products that are either mildly acidic or mildly alkaline.
Foaming
Foaming potential is one of LAPB’s most consistent contributions to a formula. It boosts both the volume and the stability of lather when used in combination with primary anionic surfactants, giving your finished product a richer, more pleasant sensory profile.
Antistatic and conditioning
Beyond its function as a surfactant, LAPB offers mild conditioning and antistatic benefits, which are useful in hair care applications where you want to add a touch of manageability to the formula without introducing a separate conditioning agent.
Compatibility
As an amphoteric, LAPB plays well with anionics, non-ionics and cationics alike. It’s a versatile building block for complex surfactant blends, including conditioning shampoos or 2-in-1 formats where you’re combining cleansing and conditioning actives in a single product.
Gentle on skin
LAPB has a well-established mild profile, making it a go-to choice for products where skin compatibility is a priority. It helps reduce the irritation potential of harsher anionic surfactants without sacrificing cleansing performance, an important balance for sensitive skin products.

Frequently asked questions
Is Lauramidopropyl Betaine safe for use in leave-on and rinse-off products?
Yes. LAPB has a well-established safety profile for rinse-off products such as shampoos, body washes and facial cleansers. For leave-on products, you’ll want to review your specific use level and target demographic, and we’d recommend checking the relevant safety assessment requirements under UK/EU cosmetics regulations.
What’s the typical use level for LAPB in a shampoo or body wash?
You’ll generally see LAPB used at between 2% and 8% active in rinse-off personal care formulations, depending on the desired foam profile and the overall surfactant blend. In I&I cleaning products, use levels can vary more widely based on the application.
How does LAPB compare to Cocamidopropyl Betaine (CAPB)?
The two are closely related and often interchangeable, but LAPB tends to offer improved mildness in certain formulations due to its slightly different fatty acid chain. In practice, the choice often comes down to your specific formulation, product availability and cost-in-use.
What grades and concentrations are available?
LAPB is typically supplied as an aqueous solution, most commonly at 30% active content, though other concentrations are available. Get in touch with our team to discuss what’s available and what makes sense for your process.
Are there any compatibility issues to be aware of?
LAPB is broadly compatible with most surfactants, but as with any amphoteric, you should watch for interactions at extreme pH values. It’s also worth testing its compatibility with high concentrations of electrolytes, which can affect the viscosity of your finished product.
What are the storage and handling requirements?
Store your LAPB in a cool, dry place away from direct sunlight and frost.
It has a shelf life of around 12 months under recommended storage conditions. Standard precautions for liquid surfactant handling apply.
