Thickness is a system property
A thickening agent in surfactant chemical development is usually a viscosity modifier for a wash or cream, not a rheology polymer for paint. Personal-care and detergent viscosity is built from the interaction of an anionic (often an ether sulphate), an amide or betaine, salt and water. Changing one piece without naming the others is why a “thickener sample” does nothing in the customer’s bottle.
Dyna Glycols manufactures Amides as the main foam boosters and viscosity builders in shampoos and bath products, PEG esters that thicken oil-in-water creams, glyceryl esters that structure creams, and glycol distearate types that pearl. Each is a different job. A pearlising wax will not salt-thicken a sulphate blend. An amide will not replace glyceryl stearate in a lotion.
Amides and betaines in wash products
Coco monoethanolamide, coco diethanolamide, lauric and oleic alkanolamides are the catalogue amide points. Super-amide versus 1:1 diethanolamide changes residual free amine and the way the grade builds viscosity — put that process difference on the TDS. Ethoxylated coco monoethanolamide (3 or 5 EO) handles more easily as a liquid. Cocamidopropyl betaine and coco betaine types are amphoteric partners: they improve mildness, stabilize foam in hard water and help salt thickening next to anionics.
State the primary anionic, its active matter, the salt you already add, and the target viscosity at the filling temperature. Cold-process liquid amides are not interchangeable with flake CMEA without a process check: the flake must be melted into the sulphate paste at the right point or it seeds and haze. Personal Care Chemicals briefs should also flag any residual diethanolamine or nitrosamine policy so the amide type is chosen against that limit.
Esters that thicken or pearl, not detergents that foam
Polyethylene Glycol (PEG) Esters such as PEG-100 stearate types thicken oil-in-water creams, often next to Glyceryl Esters such as glyceryl stearate. Monoester content drives emulsifying power; a distilled high-mono glyceryl stearate is not interchangeable with a mixed mono/di of the same melting point. Self-emulsifying grades include a hydrophilic partner — say whether that partner may be a soap or an ethoxylate.
Glycol Esters of ethylene glycol distearate types pearl in wash products. Pearl quality depends on the rest of the surfactant base, so trial in the actual shampoo, not in water. They are opacifying waxes, not foam boosters. Overheating the pearl slurry darkens the ester and raises acid value. Melt uniformly and cool with the mixing programme the mill already uses.
How to specify
Send the surfactant skeleton (anionic type and active, current amide or betaine, salt), target viscosity, appearance (clear, pearly, cream) and any DEA or PEG-free constraint. Name INCI where the formula already uses it. Dyna Glycols will sample an amide, betaine, PEG ester or glycol ester against that system rather than a generic “thickener” from another family.
Specification checklist
Put the application, the substrate, temperature, pH and any APEO or formaldehyde limit on the first enquiry. INCI or chemical names, cloud point, hydroxyl value, saponification value and colour are the numbers Dyna Glycols can lock on a TDS for this Thickening agents topic. A warehouse nickname is not a specification.
Samples and documents
Request a laboratory sample of the related Thickening agents grade together with the current SDS and TDS. The certificate of analysis is issued for the shipping lot after manufacture at Kandla SEZ. Once the trial is approved, freeze the identity tests so later drums of this chemistry match the article you evaluated.
