Sodium lauroyl sarcosinate (INCI), also known as sarkosyl, is an anionic surfactant derived from sarcosine used as a foaming and cleansing agent in shampoo, shaving foam, toothpaste, and foam wash products.
This surfactant is amphiphilic due to the hydrophobic 12-carbon chain (lauroyl) and the hydrophilic carboxylate.
Since the nitrogen atom is in an amide linkage, the nitrogen is not pH active and is neutrally charged in all aqueous solutions regardless of pH.
The carboxylate has a pKa of about 3.6 and is therefore negatively charged in solutions of pH greater than about 5.5.
pH-sensitive vesicles can be prepared using this surfactant with another cationic or water-insoluble amphiphiles such as 1-decanol.
Addition of an mixture of equal parts of sodium lauroyl sarcosinate and the non-ionic surfactant sorbitan monolaurate (S20) to water led to the formation of micelle-like aggregates, even though neither surfactant formed micelles when present alone.
Such aggregates can help carry other small molecules, such as drugs, through the skin.
Oramix L 30 is used as a surfactant and emulsifier in all shampoos, toothpastes, body washes, liquid hand soaps, laundry detergents, make-up products and many other cosmetic products.
Oramix L 30 is a natural chemical originating from coconut.
The real problem in Oramix L 30 production management is that it is contaminated with 1,4 dioxane, which is a carcinogen.
Oramix L 30 is classified in the EWG cosmetics database as a neutralizer, surfactant, cleanser, emulsifier and foamer.
Oramix L 30 has the same features as SLES and SLS.
Oramix L 30 is an anionic surfactant derived from the amino acid sarcosine and a natural fatty acid.
The similarity of the structure of Oramix L 30 with soap provides a good flash foam with better solubility and crystallinity and better resistance to hard water.
Oramix L 30, an accepted contraction of Oramix L 30, is an anionic detergent and surfactant used in many personal care products.
Oramix L 30 is an inexpensive and very effective foamer.
The chemical formula of Oramix L 30 is CH3(CH2) 11 (OCH2CH2)nOSO3Na.
Sometimes the number represented by n is specified in its name.
Oramix L 30 , also known as N -methylglycine or N –methylaminoacetic acid, is derived from the decomposition of creatine or caffeine.
Oramix L 30 is also a naturally occurring amino acid found in marine animals.
The ingredients in this report are each an amide comprising a fatty acyl residue and sarcosine, with connectivity occurring via the nitrogen atom of sarcosine and the carbonyl of the fatty acyl residue.
These ingredients are either free acids (the carboxylic functional group of the sarcosine residue), or are simple salts thereof.
The salts in this report recite the term “sarcosinate” in the name, and were referred to in the previous report as “sarcosinates” or “sarcosinates amides.”
Since these previously utilized terms could erroneously be interpreted to mean esters or amides with connectivity through the carbonyl of sarcosine, these salts are hereto referred to simply as fatty acyl sarcosine salts.
Oramix L 30 is the salt of lauryl sarcosine.
Oramix L 30 a powder or liquid and is derived from coconut.
Coconuts grow on the cocos nucifera, or coconut palm tree.
Coconut palms grow around the world in lowland tropical and subtropical areas where annual precipitation is low.
Widely cultivated, healthy coconut palms produce 50 nuts per year, and the tree can be used to produce everything from food and drink to fibers, building materials, and natural ingredients.
Oramix L 30 is a surfactant that allows water and oil to mix, allowing things to become clean.
Oramix L 30 also acts as a conditioning agent.
Oramix L 30 can be found in hundreds of personal care products such as shampoo, shaving cream, facial cleanser, soap, makeup, and other products.
Oramix L 30 is made with coconut acid and sarcosine, which is a breakdown product of creatine or caffeine.
Creatine is a natural amino acid found in muscle and body tissue.
Commercially, the ingredient is made in the presence of sodium hydroxide; it is then purified by recrystallizing it from alcohol or by acidifying it with mineral acid, separating the free acid, and neutralizing the free acid.
Oramix L 30 , like sodium lauryl sulfate, is a cleansing and foaming agent, but that is where the similarities end.
Derived from sarcosine, an amino acid that occurs naturally in the body, Oramix L 30 is frequently heralded for being a thorough cleanser but also for being gentle.
Oramix L 30 works by attracting excess oil and dirt, then carefully removing the grime from the hair by emulsifying it so it rinses easily away with water.
In addition to cleaning the hair, regular use of a shampoo with sodium lauroyl sarcosinate has also been shown to improve the appearance of the hair (especially locks that are damaged) by boosting shine and body.
Amino acid-based surfactants are used in academics and industry.
Oramix L 30 (SDDS) is such an amino acid-based surfactant having applications in pharmaceutical, food, and cosmetic formulations.
Although the surface properties of this surfactant have been studied in the presence of univalent cationic and anionic salts, there is no report on such solution in the presence of higher valencies.
In this experiment, critical micelle concentration (CMC) of Oramix L 30 from tensiometry, conductometry, and fluorimetry has been determined. In each case, CMC decreases with increasing salt concentration.
Counterion binding of micelles (β), diffusion coefficient (D0), and surface properties, e.g., Gibbs free energy for micellization (ΔGm0), Gibbs surface excess (Γmax), area of exclusion per surfactant monomer (Amin), surface pressure at CMC (πcmc), etc., have been evaluated using methods such as tensiometry, conductometry, and fluorimetry.
The hydrodynamic radius of Oramix L 30 in the presence of different salts was measured by the light scattering method. Aggregation number and shape of micelle have been determined by small-angle neutron scattering experiment.
The nature of amphiphilic packing and the aggregation numbers of the assemblies have also been explored.
The results from different experiments have been rationalized and represented systematically.
