How to Choose an APG Surfactant for Cleaning Products
You're considering an APG surfactant for a cleaner. Should you choose a short-chain grade, a broader carbon-chain blend, or a material designed mainly to help other ingredients stay dissolved?
Start with the cleaning job and the foam limit. For an alkaline concentrate, prioritize documented solubility and hydrotropic performance. For hand dishwashing, evaluate grease removal and foam endurance. For machine cleaning, look for demonstrated low-foam behavior. Then compare candidates at equivalent active content and at the intended use dilution. [1, 2, 3]
Carbon-chain length helps narrow the search, but it doesn't identify the winning grade by itself. The rest of the formula, the soil, and the way the product is used all belong in the decision.
What an APG surfactant contributes
APG stands for alkyl polyglucoside. These surfactants combine glucose-derived groups with fatty alcohol-derived chains. They're nonionic, meaning their surface-active molecules don't carry an ionic charge. Commercial grades can support wetting, cleaning, foaming, or solubilization, with different grades emphasizing different functions. [1, 4]
Wetting helps a cleaning solution spread over a surface. Emulsification helps disperse oily material in water. Hydrotropy is a different formulation role. A hydrotrope helps increase the solubility of another surfactant in the formula, which can be useful in a concentrated cleaner containing substantial builders or alkali. [2]
That distinction matters when writing a purchasing brief. An ingredient selected to keep a concentrate homogeneous may serve a different purpose from one selected to provide most of its detergency.
Compare the actual grade specifications
The examples below show how commercial materials differ. Use them as reference points when requesting specifications for the exact grade and region you're evaluating.
Manufacturer example | Published chemical description | Approximate active content | Useful selection distinction |
BASF Glucopon 215 UP | C8–C10 alkyl polyglucoside | 64% | A reference for shorter-chain APGs used in wetting and high-foam applications. |
BASF Glucopon 425 N/HH | C8–C16 alkyl polyglucoside | 50% | A broader chain distribution with wetting and high-foam application guidance. |
BASF Glucopon 600 CSUP | C10–C16 alkyl polyglucoside | 52% | A longer-chain distribution used in emulsification and high-foam applications. |
Nouryon AG 6206 Natural | Hexyl glucoside | 75% | A related short-chain glucoside positioned for low-foam hydrotropic use. |
The BASF figures come from its European portfolio guide. Nouryon separates specifications from typical characteristics in its product data sheet. These published figures are screening information, not California Chemical specifications or proof of interchangeability. Obtain current grade documents before setting acceptance limits. [5, 6]
Notice the foam distinction. Nouryon describes AG 6206 grades as low foaming and AG 6210 as medium to high foaming. Both use short-chain alcohols. A rule such as ‘shorter chain means lower foam’ misses differences within the family. [3]
Match the grade to the cleaning job
Hand dishwashing and other products where foam matters
Include cleaning performance and foam persistence under soil loading in your screen. BASF identifies APGs for manual dishwashing and documents an example blend containing APG, an ether sulfate, betaine, and an alcohol ethoxylate. This supports evaluating APG as part of a surfactant system, rather than assuming it must work alone. [1, 7]
For your trials, record the soil, water hardness, temperature, dilution, and cleaning endpoint. Measure soil removal separately from foam. A taller foam column doesn't establish that more grease has been removed.
Alkaline concentrates and degreasers
Look for grade-specific evidence on solubility in the intended alkali and builder system. Nouryon's hydrotrope guide shows that the amount needed depends on the other nonionic surfactant and the type and amount of builders. A grade that helps one concentrate remain homogeneous may need a different level in another. [2]
Define both the concentrate and the diluted cleaner. A concentrate that looks acceptable in the container still needs evaluation after dilution with the water customers will use.
Machine cleaning and foam-sensitive processes
Check foam requirements early for automatic dishwashing, recirculating cleaning, or floor-cleaning equipment. Dow positions TRITON CG-50 for applications requiring high, stable foam, while Nouryon offers low-foam glucosides. The term nonionic therefore doesn't tell you whether a material will suit a low-foam process. [4, 6]
Evaluate the complete blend under representative agitation and soil loading. If foam control is essential, make it an acceptance criterion before optimizing the rest of the formula.
Compare active content before comparing dosage or price
A supplied APG raw material usually includes water. Its percentage in your batch is therefore different from the active surfactant percentage it contributes. Manufacturer examples include Dow's 50% active TRITON CG-50 and Nouryon's 75% active AG 6206 Natural. [4, 6]
Consider a hypothetical calculation for a 100 kg batch targeting 2 kg of active surfactant from the candidate material. A grade confirmed as 50% active requires 4.00 kg. A grade confirmed as 65% active requires about 3.08 kg. If water is the only balance component, adjust the added water to maintain the same batch weight.
This is a concentration calculation, not a recommended use level or an equivalent-performance claim. Confirm the supplier's analytical basis. A dry-solids result may include material other than the surfactant, so don't silently substitute solids for active matter.
For purchasing, divide the price per kilogram of supplied material by its active fraction to compare cost per kilogram of active. Then compare cost at the dosage that actually meets your cleaning requirements. Include any additional hydrotrope, defoamer, or processing requirement in that assessment.
Comparing candidates for a cleaning project? Discuss your application with California Chemical and share the target dilution, foam limit, and proposed grade so the conversation starts with the specifications you need.
Check formulation fit and handling
Review the pH measurement conditions, not just the number. For example, Nouryon specifies the pH of AG 6206 Natural in a 2% water solution. That value doesn't establish the pH of a finished cleaner or its permitted operating range. [6]
Make viscosity comparisons equally specific. Ask for the temperature and test method, then check whether the material can be pumped and incorporated under your production conditions. Follow the supplier's storage and processing instructions rather than choosing a heating temperature from a generic APG guide.
Include builders, chelants, solvents, fragrance, preservatives, and other surfactants in the evaluation. Nonionic character provides useful blending options, but it doesn't establish complete-formula compatibility. Hydrotropic performance depends on the surrounding formulation. [2]
For a clear cleaner, assess appearance after all additions and after dilution. For a product used on glossy surfaces, include drying marks, residue, and rinsing in the performance criteria. Evaluate the intended surface itself, including any coating or finish.
Run a comparison that answers the buying question
Start with a small set of documented candidates and a consistent base formula. Keep an approved product or current formula as the control when one exists. Match active content for the initial comparison, and record addition order, mixing, temperature, and equilibration time.
Then test the complete products at their intended dilutions. Use representative soils and surfaces, and set pass criteria for cleaning, foam, appearance, and residue before judging the results. BASF's published hard-surface example specifies the soil, substrate, active concentration, pH, and temperature. That context is essential when deciding whether performance data apply to your product. [7]
Promising candidates should proceed through stability and packaging checks appropriate to the product's storage and use. If a candidate needs a different dose or blend adjustment, evaluate that optimized formula separately from the initial matched-active comparison.
What to check when the formula behaves differently
Use the timing of the change to choose the next investigation. These are practical diagnostic steps, not a diagnosis of every cloudy or unstable cleaner.
· Cloudiness during manufacture. Verify the material code, active-content calculation, addition order, and temperature. Compare the base before and after fragrance or other difficult-to-incorporate additions.
· Haze or separation after dilution. Check the actual dilution and water quality. Compare against the intended water-hardness range and assess the full surfactant, builder, and solvent balance.
· Excess foam in use. Check whether the replacement grade was selected for high foam, whether the active dose increased, and whether the test reflects the equipment's agitation.
· A change after switching supplier or grade. Compare composition, concentration, pH test conditions, residual alcohol limits, and lot documents. Reassess processing and finished-product performance before approving the substitution.
Change one variable at a time where practical. Adding more APG before identifying the cause can obscure which part of the formula needs attention.
What to gather before requesting a grade
A useful specification discussion starts with a short application brief.
· Product type, target soil, surface, cleaning method, and intended dilution.
· Concentrate and use-solution pH, water hardness, temperature, and foam limits.
· Relevant co-ingredients and requirements for clarity, residue, odor, and color.
· Exact trade name, manufacturer, chemical identity, chain distribution, and active-content basis.
· Current technical data sheet, specification, safety data sheet, and representative certificate of analysis, plus any required sourcing or environmental documentation.
California Chemical lists CALCHEM CCG APG and Lauryl Glucoside. Ask for the current documents for the proposed material and discuss its fit for your cleaning application. A catalog name alone doesn't establish chain distribution, active content, or processing requirements.
Frequently asked questions
Is APG the same as decyl glucoside
APG describes a family. Decyl Glucoside is an ingredient name used within that family, including as the INCI name for BASF Plantacare 2000 UP. INCI is cosmetic ingredient nomenclature. For cleaning-grade selection, obtain the exact commercial identity and specifications as well. [8]
Can an APG replace an alcohol ethoxylate
It may be a candidate for reformulation, but a one-for-one replacement needs evidence. Check the original surfactant's role, then re-evaluate cleaning, foam, solubility, dilution behavior, and cost. APG and alcohol ethoxylate blends also appear in manufacturer formulations, so partial replacement or a blend may be worth screening. [7]
How much APG should a cleaning formula contain
There's no universal percentage. Start with the exact supplier grade's application guidance and define the active concentration delivered at use. A ready-to-use spray and a concentrate diluted before cleaning require different dosage calculations, even when the cleaning target is similar.
Does using APG make a cleaner Safer Choice certified
No. EPA states that using ingredients on its Safer Chemical Ingredients List doesn't authorize Safer Choice claims. The finished product must complete the applicable review and qualification process. Check the exact ingredient documentation and the requirements for your intended claim. [9]
