Chitosan Succinamide is a chemically modified chitosan derivative produced through succinylation of chitosan. It is also known as N-succinylchitosan or chitosan, N-(3-carboxy-1-oxopropyl). Chitosan Succinamide belongs to the family of chitosan-based polymeric cosmetic ingredients and is primarily recognized for its film-forming functionality.
Chitosan Succinamide combines the polymeric characteristics of chitosan with succinyl-derived functional groups. This modification can change the water compatibility, surface properties and formulation behavior of the original chitosan polymer.
Chitosan Succinamide is a succinylated derivative of chitosan in which succinyl groups are introduced onto the chitosan polymer. The resulting material has characteristics that differ from unmodified Chitosan.
It is used in cosmetic formulations where a polymeric film-forming ingredient is required. Commercial materials containing Chitosan Succinamide have also been developed for skin-care, hair-care and cleansing applications.
The principal cosmetic function of Chitosan Succinamide is film forming. A film-forming ingredient can create a continuous layer on skin, hair and/or nails.
This property makes Chitosan Succinamide useful in formulations where surface conditioning, moisture retention, substantivity or improved cosmetic feel is desired.
Chitosan Succinamide can be incorporated into selected skin-care formulations. Its polymeric film-forming behavior can contribute to the surface characteristics and sensory properties of creams, lotions, serums and other personal-care products.
Commercial Chitosan Succinamide grades are marketed for skin-care applications and can provide filmogenic and moisturizing properties.
Chitosan Succinamide can also be used in hair-care formulations. Its film-forming behavior can help improve the surface characteristics and feel of hair.
Potential applications include shampoos, conditioners, hair treatments and other hair-care formulations where polymeric deposition and conditioning characteristics are desired.
Chitosan Succinamide has been used in cleansing formulations where it can contribute to foam stabilization and sensory properties. Certain commercial grades are described as supporting foam stability while providing a soft skin feel.
This makes it suitable for evaluation in shampoos, cleansing products and other wash-off formulations.
Succinylated chitosan materials can provide water-retention characteristics. The polymeric structure can interact with water and contribute to the moisturizing profile of suitable formulations.
However, the actual moisture-retention performance depends on molecular weight, degree of substitution, concentration, formulation pH and other formulation components.
Certain commercial grades of Chitosan Succinamide are positioned as ingredients that can improve skin feel by reducing excessive tackiness and providing a smoother, softer sensory profile.
The final sensory effect depends on the specific grade and formulation composition.
Some commercial Chitosan Succinamide products are marketed for a smooth or silicone-like sensory profile. This does not mean that Chitosan Succinamide is chemically a silicone. It refers to the sensory characteristics that a particular grade may provide in a cosmetic formulation.
Chitosan is the parent polyaminosaccharide, while Chitosan Succinamide is a chemically modified derivative containing succinyl groups.
The modification can alter properties such as water compatibility, charge behavior, viscosity and film-forming characteristics.
Chitosan PCA is the pyrrolidonecarboxylic acid salt of chitosan, whereas Chitosan Succinamide is a succinylated chitosan derivative.
Their chemical structures and formulation properties are different. Chitosan PCA is recognized for film forming, humectant and skin-conditioning functions, while Chitosan Succinamide is primarily identified as a film-forming ingredient.
Chitosan Lactate is a lactate salt of chitosan, while Chitosan Succinamide is a succinylated chitosan derivative.
They should therefore be treated as separate cosmetic raw materials with individual specifications.
Chitosan Succinamide is polymeric and therefore does not have one universal molecular-weight value for all commercial grades.
Molecular weight can vary according to the starting chitosan, manufacturing process and degree of modification.
The degree of succinylation or substitution can affect solubility, charge characteristics, viscosity and film formation.
Because this parameter is manufacturing- and grade-dependent, the exact value should be taken from the supplier's technical documentation.
Succinylation can improve the water compatibility of chitosan-based materials compared with unmodified chitosan. However, the actual solubility of Chitosan Succinamide depends on the grade, molecular weight, degree of substitution, pH and concentration.
Commercial Chitosan Succinamide materials may be supplied as aqueous solutions rather than dry powders, depending on the grade.
Important formulation factors include:
The exact specifications should always correspond to the commercial grade being supplied.
Chitosan Succinamide can be evaluated in:
Chitosan Succinamide is a succinylated derivative of chitosan, also known as N-succinylchitosan.
The INCI name is CHITOSAN SUCCINAMIDE.
The commonly documented CAS number for Chitosan Succinamide / N-succinylchitosan is 78809-92-4.
Its recognized cosmetic function is film forming.
Yes. Film forming is its recognized cosmetic function.
Yes. It can be used in selected skin-care formulations, including creams, lotions and other personal-care systems.
Yes. It can be evaluated in shampoos, conditioners, hair treatments and other hair-care products.
Succinylated chitosan materials can provide water-retention characteristics, although performance depends on the grade and formulation.
Water compatibility can be improved through succinylation, but actual solubility depends on the grade, degree of substitution, molecular weight and pH.
No. Chitosan Succinamide is a chemically modified derivative of Chitosan.
No. Chitosan PCA is a pyrrolidonecarboxylic acid salt, while Chitosan Succinamide is a succinylated chitosan derivative.
No. Chitosan Lactate is a lactate salt of chitosan, while Chitosan Succinamide is a succinylated derivative.
There is no single universal molecular-weight value because it is a polymeric material and commercial grades vary.
Important parameters can include appearance, identification, solids content, pH, viscosity, molecular weight, degree of deacetylation, degree of substitution, moisture, ash, solubility and microbiological quality.
