What Is Sodium Carboxymethyl Tamarindus Indica Seed Gum?
Sodium Carboxymethyl Tamarindus Indica Seed Gum is a plant-derived polymer made from the seeds of the tamarind tree, a tropical species long valued for its fruit. Chemists modify the natural seed gum by attaching carboxymethyl groups, then neutralize the material with sodium to improve its water solubility. The result is a smooth, easy-to-handle powder that swells in water to create a soft, cushiony texture.
Tamarind seed gum itself has been used for generations in food and textiles as a thickener. As cosmetic formulators searched for botanical alternatives to synthetic polymers in the 1990s they began experimenting with this gum. The carboxymethylated, sodium-salt version offered better consistency, stability and skin feel, earning it a place in modern skin and hair care lines.
The manufacturing process starts with cleaned, dehusked tamarind seeds that are milled into a flour. This flour reacts with monochloroacetic acid under controlled alkaline conditions, which adds the carboxymethyl groups. After thorough washing and drying, the material is neutralized with sodium hydroxide, filtered and milled again to obtain a uniform cosmetic-grade powder.
You will most often spot Sodium Carboxymethyl Tamarindus Indica Seed Gum in moisturizers, serums, sheet masks, soothing gels, leave-in conditioners, styling creams, shampoos and body lotions where it helps create a pleasing glide and subtle film on skin or hair.

If any uncomfortable reaction develops discontinue use and consult a healthcare professional if symptoms persist or worsen.
Comedogenic Rating
Rating: 0 (non-comedogenic)
Sodium Carboxymethyl Tamarindus Indica Seed Gum is a large, water-soluble polysaccharide that sits on the surface of skin then slowly rinses away without clogging pores. It contains no oily or waxy residues that would collect inside follicles and its film-forming action is light and breathable. Laboratory data and user reports show no link between this gum and increased comedone formation.
Because of its rating of 0 it is generally suitable for acne-prone or breakout-prone skin. The only caveat is individual allergy to tamarind which is rare.
Summary
