Description

Coco Betaine is an amphoteric surfactant for cosmetic use, particularly suitable for rinse-off cleansing formulations such as shower gels, shampoos, body cleansers and liquid soaps.

It is commonly used as a co-surfactant to improve the mildness of a formulation, support foam formation and reduce the harsh feel of systems based on anionic or non-ionic surfactants. It can also help adjust viscosity in suitable systems, especially when working with compatible salts and surfactant bases.

According to the technical data sheet, its approximate active matter content is 29% - 33%; it is highly soluble in water and has limited solubility in ethanol. The pH is measured in a 20% solution at 20 C.

How to incorporate

Incorporate into the aqueous phase or surfactant mixture, stirring slowly to avoid excessive foaming.
Adjust the final pH of the formulation according to its intended use and check viscosity, stability and packaging compatibility.
Always test finished cosmetic formulations for stability, preservation and tolerance before use or sale.

Indicative formulations with Coco Betaine

Three starting formulations for assessing its use as an amphoteric co-surfactant in rinse-off cleansing products. They must be tested and validated before use or sale, checking pH, viscosity, stability, preservation, packaging compatibility and tolerance.

1. Mild fragrance-free shower gel - 1 litre

A simple formulation for normal or delicate skin, with mild foam and a recommended final pH of 5,2 - 5,8.

Distilled water: q.s. to 1000 g.
Coco Betaine: 180 g.
Coco Glucoside: 120 g.
Decyl Glucoside: 60 g.
Vegetable liquid glycerine: 30 g.
Clear Xanthan Gum: 3,5 g.
Geogard 221 / Cosgard: 10 g.
Citric acid in a 20% solution: q.s. to adjust pH.

Method: hydrate the xanthan gum in the glycerine, gradually add the water and mix until a gel forms. Incorporate the surfactants slowly, avoiding aeration. Adjust the pH, add preservative, mix until homogeneous and leave to rest for 24 hours before assessing viscosity.

2. Basic mild shampoo - 1 litre

An indicative base for normal hair or a sensitive scalp. Always validate its performance on the hair, foam, rinsing and final pH of 5,0 - 5,5.

Distilled water: q.s. to 1000 g.
Coco Betaine: 180 g.
Decyl Glucoside: 120 g.
Coco Glucoside: 80 g.
Propanediol: 30 g.
Vegetable liquid glycerine: 25 g.
Clear Xanthan Gum: 2,5 g.
Geogard 221 / Cosgard: 10 g.
Citric acid in a 20% solution: q.s. to adjust pH.

Method: premix the humectants and gum, incorporate the water and allow to hydrate. Add the surfactants slowly, adjust the pH at the end and check viscosity after resting. If fragrance or essential oil is added, solubilise it and validate stability.

3. Liquid hand soap with mild foam - 1 litre

A starting formulation for frequent hand washing. Adjust viscosity and sensory properties to suit the dispenser packaging.

Distilled water: q.s. to 1000 g.
Coco Betaine: 200 g.
Coco Glucoside: 150 g.
Decyl Glucoside: 50 g.
Vegetable liquid glycerine: 20 g.
Clear Xanthan Gum: 3 g.
Geogard 221 / Cosgard: 10 g.
Citric acid in a 20% solution: q.s. to adjust pH.

Method: prepare the gelled aqueous phase, incorporate the surfactants with gentle stirring and adjust the pH to 5,2 - 5,8. Allow to deaerate, check viscosity and carry out a preservation test before scaling up.
