Amidated Pectin is a modified plant-derived polysaccharide produced by introducing amide groups into pectin. It is generally associated with amidated low-methoxyl pectin, in which some of the carboxyl groups of pectin are converted to amide groups. This modification changes the polymer's interaction with water, ions and other formulation components.
Pectin itself is a natural polysaccharide with a backbone primarily consisting of α-(1→4)-linked D-galacturonic acid units. Amidation modifies a portion of the carboxyl functionality without changing the basic pectin polysaccharide structure.
Amidated Pectin hydrates and interacts with water, making it useful as a functional hydrocolloid in suitable aqueous formulations. Its rheological behavior depends on molecular weight, degree of esterification, degree of amidation, concentration, pH and ionic conditions.
Amidated Pectin can contribute to viscosity and formulation consistency. The level of viscosity modification is grade-dependent and should be evaluated according to the specific commercial material and formulation conditions.
Amidated low-methoxyl pectins have different ionic interaction characteristics from conventional high-methoxyl pectins. Their gelation behavior can involve ionic interactions with calcium, with the exact behavior depending on degree of esterification, degree of amidation and calcium concentration.
Amidated pectin can provide useful interfacial and rheological functionality in suitable emulsion systems. Research on amidated pectin has reported improved emulsifying properties following amidation compared with the corresponding non-amidated pectic material.
Amidated Pectin can be evaluated in creams, lotions, gels, masks and other cosmetic systems requiring plant-derived polymeric functionality, viscosity modification or formulation stabilization.
Amidated Pectin can be considered for selected hair-care formulations where a polysaccharide-based rheology modifier or formulation stabilizing material is required.
Its polymeric structure and ionic interactions make Amidated Pectin suitable for evaluation in selected gel systems. Formulation performance depends strongly on pH, calcium or other ions, concentration and grade characteristics.
Regular Pectin contains carboxyl groups that may be esterified to different degrees. Amidated Pectin additionally contains amide groups introduced through chemical modification. Amidation can alter gelation, calcium response and rheological behavior.
Amidated low-methoxyl pectin is generally distinguished from conventional low-methoxyl pectin by its degree of amidation.
Amidated Pectin is a heterogeneous polymeric material rather than a single small molecule. Therefore, molecular weight, degree of esterification, degree of amidation, methoxyl content, viscosity and gel strength may vary between commercial grades.
The Indian FSSAI specification for Pectin lists CAS 9000-69-5, minimum galacturonic acid of 65%, maximum loss on drying of 12%, maximum acid-insoluble ash of 1%, maximum total insolubles of 3%, maximum nitrogen of 2.5%, and maximum degree of amidation of 25%. These are pectin specification limits and should not automatically be treated as the release specification for every Amidated Pectin cosmetic grade.
A published study of amidated celery pectin reported a degree of esterification of 31%, degree of amidation of 16%, degree of acetylation of 2%, and anhydrouronic acid content of 68%. These are research-sample values, not universal commercial specifications.
Amidated Pectin can be evaluated in:
Amidated Pectin is a chemically modified pectin in which some of the carboxyl groups of pectin are converted into amide groups.
Amidated Pectin is generally covered under the pectin identity CAS 9000-69-5. The exact CAS assignment should be confirmed against the specific commercial grade and supplier documentation.
The relevant cosmetic ingredient identity is generally associated with Pectin when the material is represented as pectin. The exact INCI designation should be verified against the supplied cosmetic-grade raw material documentation.
The starting material pectin is plant-derived, but amidated pectin is chemically modified. It should therefore be described as a modified plant-derived polysaccharide rather than an unmodified natural pectin.
It can contribute to viscosity and rheology modification in suitable formulations, although the exact performance is grade- and formulation-dependent.
Its functions can include hydrocolloid behavior, viscosity modification, formulation stabilization and interaction with ionic components.
Amidated Pectin contains amide groups introduced onto the pectin polymer, which changes its functional behavior compared with unmodified pectin.
It is a low-methoxyl pectin that has additionally undergone amidation. Amidated low-methoxyl pectins are recognized as a distinct class of pectin derivatives.
No. It is a heterogeneous polymeric material and does not have one fixed molecular formula or molecular weight.
Important parameters include degree of amidation, degree of esterification, galacturonic acid, moisture, ash, viscosity, pH, methoxyl content, gel strength and microbiological quality.
