Sodium Lauroyl Sarcosinate

The Basics On Sodium Lauroyl Sarcosinate

What is Sodium Lauroyl Sarcosinate?

Sodium lauroyl sarcosinate is a synthetic or plant-derived surfactant (cleansing agent) that also works as an emulsifier.

What are other names for Sodium Lauroyl Sarcosinate?

GLYCINE, N-METHYL-N-(1-OXODODECYL)-, SODIUM SALT, GLYCINE, NMETHYLN(1OXODODECYL), SODIUM SALT, N-DODECANOYLSARCOSINE SODIUM SALT, N-METHYL-N-(1-OXODODECYL)- SODIUM SALT GLYCINE, N-METHYL-N-(1-OXODODECYL)GLYCINE, SODIUM SALT, SODIUM LAUROYL SARCOSINATE, SODIUM N-LAUROYL SARCOSINATE, SODIUM N-LAUROYLSARCOSINATE, SODIUM SALT GLYCINE, N-METHYL-N-(1-OXODODECYL)-, and SODIUM SALT N-METHYL-N-(1-OXODODECYL)GLYCINE

What is Sodium Lauroyl Sarcosinate used for?

Sodium lauroyl sarcosinate is a synthetic or plant-derived surfactant (cleansing agent) that also works as an emulsifier. It is most often used in face and body cleansers and shampoos but is sometimes also used in leave-on products. This versatile ingredient works well with various glycols, silicones, solvents, and phosphate esters. Safety assessments have confirmed this ingredient is non-irritating and non-sensitizing when applied to human skin in amounts (up to 15% in rinse-off and 5% in leave-on products) that are approved for use in cosmetics.

Sodium Lauroyl Sarcosinate During Pregnancy

What we know about using Sodium Lauroyl Sarcosinate while pregnant or breastfeeding

Limited information available.

A prenatal developmental toxicity study (OECD Guideline 414) was conducted for Sodium Lauroyl Sarcosinate (95% pure) in Sprague-Dawley rats.26 Groups of 24 gravid female rats were dosed once daily by gavage with 0, 30, 100 and 250 mg/kg bw/day of the test article in distilled water on days 5-10 of gestation, and the animals were killed on day 20 of gestation. Sodium Lauroyl Sarcosinate was not embryotoxic or teratogenic. Maternal body weight gains (adjusted) in the mid- and high-dose group were decreased during gestation as compared to the controls. Feed consumption was decreased in the high dose group; the decrease was statistically significantly between days 8-11 and days 14-17 of gestation. Two high-dose dams died during the study; one on day 10 and one on day 18 of gestation. The dam that died on day 18 of gestation had sloughing on the non-glandular region of the stomach, 7 dead fetuses had sloughing in the right uterine horn, and 5 dead fetuses had sloughing in the left uterine horn, and the high-dose females killed at study termination all had sloughing on the nonglandular region of the stomach; this effect was not observed in the low or mid-dose groups. The NOAEL (maternal toxicity), LOAEL (maternal toxicity), and NOEL (developmental toxicity) were 30, 100, and ‚â•250 mg/kg bw/day Sodium Lauroyl Sarcosinate, respectively

General safety info about Sodium Lauroyl Sarcosinate from CIR

The Cosmetic Ingredient Review (CIR) Expert Panel assessed the safety of 14 fatty acyl sarcosines and their salts as used in cosmetics; all of these ingredients are reported to function in cosmetics as hair conditioning agents and most also can function as surfactants – cleansing agents. The ingredients reviewed in this assessment are composed of an amide comprising a fatty acyl residue and sarcosine, and are either free acids or simple salts thereof. The Panel relied on relevant new data, including concentration of use, and considered data from the previous CIR report, such as the reaction of sarcosine with oxidizing materials possibly resulting in nitrosation and the formation of N–nitrososarcosine. The Panel concluded that these ingredients are safe as used in cosmetics when formulated to be non-irritating, but these ingredients should not be used in cosmetic products in which N-nitroso compounds may be formed.
