A systematic literature review on the current detection tools for authentication analysis of cosmetic ingredients

Abstract

According to the Guidelines for Control of Cosmetic Products in Malaysia provided by the National Pharmaceutical Regulatory Agency (NPRA), Ministry of Health, Malaysia, cosmetic refers to any substance used on external parts of the human body. 1 The use of the cosmetic products is considered a necessity for personal hygiene, improved attractiveness, to protect skin and hair from ultraviolet light and pollutants, and slowing down of the aging process. 2 Cosmetics have been around for a long time and used daily not just by women but men as well. Hence, the consumption of these products is increasing every year. According to the Malaysian Standard on Halal cosmetics-General requirement (MS 2634:2019), 3 the definition of "personal care" is merged as

The genus Polygonum: An updated comprehensive review of its ethnomedicinal, phytochemical, pharmacological activities, toxicology, and phytopharmaceutical formulation

“…The primary utilization of the fatty acids obtained from plants was in the cosmetics industry. Palmitic, lauric, and myristic acids, detected in several Polygonum species, make up around 99% of the formulation of cosmetics, while stearic acids make up between 92% and 96% [ 102 ]. Fatty acids generally have several advantageous effects when included in cosmetic formulations, including hardening the soap, producing a rich lather, and improving the soap's velvety surface.…”

Moisturizer in Patients with Inflammatory Skin Diseases

“…Fatty acids are esters (R-COOH), the main component of animal oils and fats, and most of them are distilled by hydrolyzing triglycerides [ 30 ]. Long-chain fatty acids, such as palmitic acid and stearic acid, are commonly used.…”

Advances on Hormones in Cosmetics: Illegal Addition Status, Sample Preparation, and Detection Technology

“…In order to concentrate the analytes and minimize matrix effects, the previous sample pretreatment before instrumental analysis is usually required. In recent years, there have been several reviews reporting the commonly used sample preparation technologies for cosmetics, such as microextraction (ME), matrix solid-phase dispersion (MSPD), solid-phase extraction (SPE), and ultrasound-assisted extraction (UAE) [ 7 , 15 , 16 , 17 , 18 , 19 , 20 ]. However, the above analytes involve both essential ingredients and restricted/prohibited substances, and analytical methods are not discussed in detail.…”

“…However, the above analytes involve both essential ingredients and restricted/prohibited substances, and analytical methods are not discussed in detail. In addition, there are some comments on the analytical methods for special types of ingredients in cosmetics, such as oils [ 20 ], fragrances [ 21 ], parabens [ 22 ], dyes [ 23 ], and endocrine-disrupting chemicals [ 24 ]. Even though the pretreatment and analytical methods are summarized in detail, the analytical methods are mainly covering traditional confirmation techniques, such as liquid chromatography (LC) methods and LC with mass spectrometry (LC-MS) or tandem mass spectrometry (LC-MS/MS), rare attention is paid on the emerging analytical technologies represented by rapid detection approaches [ 2 , 19 , 25 ].…”
