| Product Name | Sodium Methyl Cocoyl Taurate |
| CAS | 61791-42-2 |
| Description | Sodium Methyl Cocoyl Taurate is a surfactant that is commonly used in personal care and cosmetic products for its cleansing and foaming properties. It is derived from coconut oil and is used in a variety of skin and hair care products, such as shampoos, body washes, facial cleansers, and shaving creams. Sodium Methyl Cocoyl Taurate is a mild surfactant, which means it is gentle on the skin and does not cause excessive dryness or irritation. It is also biodegradable, making it an environmentally friendly choice for manufacturers. In addition to its cleansing properties, Sodium Methyl Cocoyl Taurate can also act as a conditioning agent, helping to improve the texture and appearance of hair and skin. It can help to soften the skin, reduce the appearance of dryness and flakiness, and improve the overall moisture content of the hair and scalp. |
| Appearance | white to light yellow powder or granular material |
| Application | 1. Sodium methyl cocoyl taurate is commonly used in the formulation of personal care products, including shampoos, facial cleansers, and body washes. 2. It is an anionic surfactant, which means it has a negative charge and is effective at removing dirt, oil, and other impurities from the skin and hair. 3. It is a mild and gentle surfactant, making it suitable for use in products designed for individuals with sensitive skin or delicate hair. 4. Sodium methyl cocoyl taurate helps create a rich lather in personal care products, enhancing the user's experience and perception of product performance. 5. It is also used as a foam booster and can help stabilize the emulsion in a formulation. |

Sodium Methyl Cocoyl Taurate is a versatile surfactant used extensively in personal care products such as facial cleansers, liquid soaps, and shampoos. This ingredient delivers a rich, creamy foam that maintains high volume, even in formulations with substantial oil content. Renowned for its remarkable foaming properties, it effectively cleanses and degreases skin and hair while offering gentle and soft action. Moreover, Sodium Methyl Cocoyl Taurate enhances the overall sensory experience by boosting foam stability and improving resistance to hard water, making it a preferred choice for creating mild and safe cleansing products.

Understanding the physicochemical mechanisms of adsorption of polycationic-negatively charged surfactant blends onto negatively charged surfaces is useful for the design of cosmetic formulations for hair conditioners. This work investigates the adsorption of supramolecular complexes formed by a highly charged cationic homopolymer (polydiallyldimethylammonium chloride, PDADMAC) and the sulfate-free anionic surfactant sodium methyl cocoyl taurate (SMCT) onto liquid/solid interfaces.
Experimental methods and key results
· The measurement of the ζ-potential and size distribution of complexes in the bulk has been conducted. It was observed that the ζ-potential does not exhibit charge inversion across the range of surfactant concentrations examined, from values exceeding the cmc to the precipitation region.
· Dynamic light scattering analysis revealed a significant increase in aggregate size at the beginning of the phase region, as indicated by the heightened turbidity of the solution/dispersions. The adsorption on a negatively charged solid substrate was found to be closely linked to the charge of the complexes formed in the bulk, with the adsorption process controlled by diffusion kinetics.
· The research has shown that PDADMAC-SMCT mixtures have an affinity for negatively charged substrates, suggesting that they could be an effective option for sulfate-free shampoo and conditioner formulations, with adsorption times comparable to those of traditional shampoos on hair.

· Formulation of Cream Soaps
Cream soaps, such as facial cleansers, are formulated using a combination of potassium salts of various fatty acids to maintain viscosity over a wide temperature range. Differential thermal analysis and differential scanning calorimetry are used to ensure stability at different temperatures. Ingredients such as cetanol, glycerin, PEG, amphoteric, and anionic surfactants are crucial for stability improvement. The preparation involves heating and mixing various components before adjusting the pH and adding water to achieve a pH range of 9.5-10.2.
· Formulation of Cleansing Cosmetics
Cleansing cosmetics remove dirt from the face, hands, and body using anionic surfactants and potentially amphoteric surfactants and potassium salts of fatty acids. Thickening agents like ethylene glycol distearate, cetanol, saturated higher alcohols, and fatty acid alkanolamides are added to create viscous products. Different thickeners like PEG-120 methyl glucose dioleate, hydroxy methyl propyl cellulose, ethylene glycol stearate, and ethylene glycol distearate can also be used in the formulation. The preparation involves dispersing and heating various components, homogenizing, and neutralizing before adding water to achieve a pH range of 6.0-7.5.
