Sodium Phosphate is a general chemical name used for a group of sodium salts of phosphoric acid, including monobasic, dibasic and tribasic sodium phosphate. Because these forms have different chemical compositions, CAS numbers, molecular formulas, molecular weights and formulation properties, the exact grade should be identified before publishing technical specifications.
For cosmetic ingredient applications, the term Sodium Phosphate can refer to a phosphate-based ingredient used for formulation pH adjustment, buffering and other formulation-support functions. Cosmetic Ingredient Review has evaluated Sodium Phosphate and related sodium phosphate ingredients for cosmetic use under specified conditions.
The three commonly encountered forms are:
These forms should not be treated as interchangeable because their chemical identities and properties differ.
For example, Trisodium Phosphate anhydrous has CAS Number 7601-54-9, molecular formula Na₃PO₄ and molecular weight 163.94 g/mol.
Sodium Phosphate refers to sodium salts derived from phosphoric acid. Depending on the degree of neutralization, sodium phosphate can exist in monobasic, dibasic or tribasic forms.
In cosmetic formulation development, phosphate salts may be used in appropriate systems for:
The actual function depends on the specific sodium phosphate form and its concentration within the formulation.
Important technical information includes:
Sodium phosphate ingredients can be evaluated in cosmetic formulations where buffering or pH adjustment is required.
Potential applications include:
The appropriate sodium phosphate form should be selected according to the desired pH range, buffering system, formulation composition and finished-product requirements.
Sodium phosphate may be incorporated into suitable skincare formulations as part of a buffering system.
Potential applications include:
Formulators should evaluate pH, ionic strength, compatibility with active ingredients, preservatives and other formulation components.
Suitable sodium phosphate forms can be evaluated in hair-care formulations where pH control or buffering is required.
Potential applications include:
Compatibility with surfactants, conditioning agents, polymers and preservatives should be evaluated during formulation development.
Important formulation considerations include:
Hydration state is particularly important because the molecular weight and percentage composition of the material change with the amount of bound water.
Sodium Phosphate Cosmetic Raw Material Manufacturer in India is a relevant B2B search phrase for cosmetic manufacturers and personal-care formulators.
Before procurement, buyers should confirm:
Sodium Phosphate Supplier in India is a relevant commercial keyword for businesses sourcing phosphate-based cosmetic raw materials.
Supplier documentation should clearly identify whether the material is:
This distinction is important because these materials have different technical identities.
Sodium Phosphate Manufacturer and Supplier in India is a relevant B2B search phrase for businesses sourcing sodium phosphate for cosmetic and personal-care formulation development.
Potential formulation categories include:
Sodium Phosphate Bulk Supplier India is relevant for businesses requiring larger quantities for cosmetic manufacturing.
