Halal Cosmetics: A Review on Ingredients, Production, and Testing Methods

Knowledge, Perceptions and Attitudes among Sharia Practitioners in Palestine Regarding Halal Pharmaceuticals: An Exploratory Study

The purpose of this questionnaire-based cross-sectional study was to investigate the knowledge, perceptions, and attitudes regarding halal pharmaceuticals among sharia practitioners in Palestine. A total of 420 sharia practitioners with different educational levels were included. This was a cross-sectional study conducted between March and July 2021 with the use of a standardized, self-administered questionnaire. Volunteers were selected throughout Palestine using a systematic random selection approach. The data were summarized using descriptive statistics (mean, standard deviation, frequency, percentage, median, and interquartile range). The Chi-square and Fisher's exact tests were used to examine the relationship between demographic factors and the knowledge, attitude, and perception scores, respectively. The results revealed that sharia practitioners have relatively good and positive knowledge toward halal pharmaceuticals. The main knowledge of most halal pharmaceuticals was about 50.2%, yet there is still significant latitude in their knowledge of a few issues. The main attitude and perception score was about 96.4%. The results showed a positive and fair correlation between knowledge and attitude (r = 0.153, P < 0.001) and also between knowledge and perception (r = 0.341, P < 0.001). In addition, there is a good correlation between attitude and perception (r = 0.681, P < 0.001). The study concluded that better knowledge of halal pharmaceuticals is associated with positive perceptions and behaviors. The government, pharmaceutical manufacturers, religious scholars, and health care professionals should collaborate to achieve the goal of using halal medications.

Towards halal pharmaceutical: Exploring alternatives to animal-based ingredients

Halal is a crucial concept for Muslim consumers regarding consumed products, including pharmaceutical ingredients, which are essential in modern medicine. To address the issue of using porcine-sourced ingredients in pharmaceuticals, it is essential to search for halal alternatives derived from poultry, animal by-products from meat processing, marine sources, and plants. However, the complexity of this problem is further compounded by the rapid advances in innovation and technology, which can lead to adulteration of ingredients derived from pigs. Other challenges include the sustainability of alternative materials, management of waste or by-products practice, halal awareness, certification, government policies, religious adherence of consumers, food suppliers, marketers, and purchasing of products. The importance of halal and non-halal problems, specifically in the context of pharmaceutical materials, is still rarely discussed, including alternatives derived from poultry, animal by-products, marine sources, and plants. Due to the increasing global population, there is a growing need to increase awareness and concern among Muslim consumers for halal products, including pharmaceuticals. Therefore, this research aimed to investigate the importance of halal and non-halal issues in pharmaceutical ingredients, the potential impact on the Muslim community, as well as opportunities and challenges in the search for alternative ingredients.

Determinants of consumer adoption of halal cosmetics: A systematic literature review

BACKGROUND

The global halal cosmetics market is projected to grow during the forecast period. However, the factors that influenced consumers in the world to opt for halal cosmetics remain ambiguous.

OBJECTIVES

The objective of this study was to understand the universal concept of halal cosmetics and a framework of critical points that influence consumers in purchasing halal cosmetic products.

METHOD

The method used was Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement by using Web of Science and Scopus databases. This study extends the systematic literature review covering all variables in purchasing halal cosmetics as halal cosmetic is not simply a religious issue, but it is also an opportunity to increase sales and acquire a competitive advantage.

RESULTS

This study found 14 articles that mainly discussed the critical points related to religiosity and product factors, that is, ingredient, halal logo, and halal certification as the highest driver in influencing consumers to purchase halal cosmetics. Other related factors in this study are price, promotion, place, social factors, and characteristics of consumers. These factors should be taken into consideration as they provide a plus point and an extra edge to local or international manufacturers to tap the global markets for halal cosmetic products that cater to both Muslims and non-Muslims communities.

PRACTICAL IMPLICATIONS

Cosmetic manufacturers and marketers must ensure that their products suit the expectation of consumers as todays halalan and tayyiban products are being searched rather than branded products due to their cleanliness, safety, and hygienic.

ORIGINALITY/VALUE

This study is among the earliest study examining the factors of purchase intention in halal cosmetics using a systematic literature review method that integrates marketing stimulus (product, price, promotion, and place) and other stimuli (social, religious, and characteristics).

Potential Cosmetic Active Ingredients Derived from Marine By-Products

The market demand for marine-based cosmetics has shown a tremendous growth rate in the last decade. Marine resources represent a promising source of novel bioactive compounds for new cosmetic ingredient development. However, concern about sustainability also becomes an issue that should be considered in developing cosmetic ingredients. The fisheries industry (e.g., fishing, farming, and processing) generates large amounts of leftovers containing valuable substances, which are potent sources of cosmeceutical ingredients. Several bioactive substances could be extracted from the marine by-product that can be utilized as a potent ingredient to develop cosmetics products. Those bioactive substances (e.g., collagen from fish waste and chitin from crustacean waste) could be utilized as anti-photoaging, anti-wrinkle, skin barrier, and hair care products. From this perspective, this review aims to approach the potential active ingredients derived from marine by-products for cosmetics and discuss the possible activity of those active ingredients in promoting human beauty. In addition, this review also covers the prospect and challenge of using marine by-products toward the emerging concept of sustainable blue cosmetics.

Analysis of Prohibited and Restricted Ingredients in Cosmetics

The general public uses cosmetics daily. Cosmetic products contain substances (ingredients) with various functions, from skincare to enhancing appearance, as well as ingredients that preserve the cosmetic products. Some cosmetic ingredients are prohibited or restricted in certain geographical regions, such as the European Union and the United States of America, due to their potential to cause adverse effects such as cancer, birth defects, and/or developmental and reproductive disorders. However, the ingredients may be used in other regions, and, hence, the monitoring of the cosmetic ingredients actually used is important to ensure the safety of cosmetic products. This review provides an overview of recent analytical methods that have been developed for detecting certain ingredients that are restricted or prohibited by the U.S. Food and Drug Administration (FDA) and/or EU legislation on cosmetic products.

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

BACKGROUND

The use of cosmetic products is considered a necessity for beautification in our daily lives. Cosmetic products composed of natural oils or fats as a main ingredient for various beneficial properties. Fats and oils are composed of various type of fatty acids with different compositions. Hence, fatty acids profile can be an effective chemical fingerprint for authentication analysis of cosmetic products.

OBJECTIVE

This systematic review aims to enlighten the current detection tools developing for fatty acids profile authentication analyses of cosmetic ingredients based on the effectiveness, halal status, safety, advantages and disadvantages of the methods.

METHODOLOGY

The data were extracted from the scientific literatures published between October 2015 and 2020 in the Web of Science, Scopus and Google Scholar databases, and analyzed with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).

FINDINGS

Based on the systemic literature reviews, essential oil, argan oil, mineral oil, vegetable oil, and jojoba oil were among the mostly studied ingredients in cosmetics. Furthermore, a combination of more than one analytical instrument was utilized to profile fatty acids while the determination of the origin of the fatty acids is under scrutiny. The portable mass spectrometer combined with a direct inlet membrane (DIM) probe seems to be the best tool in terms of time consumption, cost, requires no sample preparation with high efficiency. The current review showed that the best cosmetic base is when the oil is composed of high concentration of fatty acids such as linoleic, oleic, stearic acid, and palmitic acids with concentration range from 19.7 - 46.30%, which offers various beneficial properties to cosmetic products.

Intention to Purchase Halal Cosmetics: Do Males and Females Differ? A Multigroup Analysis

As Muslims bound to Islamic teachings, the attitude of young millennials preferring non-halal international cosmetics is trivial. Despite the acceptance of halal food, literature on the acceptance of halal cosmetics remains scarce. The intention to purchase halal cosmetics is crucial for the sustainability of halal cosmetics manufacturers. The authors used the theory of planned behavior to identify factors influencing the purchase intention of halal cosmetics among Muslim millennials. Since cosmetics are not exclusively used by females, as males are starting to use them in their daily lives, gender was incorporated into the framework to assess its moderating effect on the relationship. Furthermore, brand image was included in the theory of planned behavior. Data were collected from three universities in Malaysia. A total of 501 responses were analyzed with smart partial least squares to run a multigroup analysis. The analysis revealed that subjective norms have a stronger effect on females, and perceived behavioral control has a greater effect on males. Although attitude and brand image have a positive effect on the intention to purchase halal cosmetics, gender has no effect. The findings are essential for halal cosmetics manufacturers to craft a marketing strategy aimed at Muslim millennials in Malaysia.

BACKGROUND

Skin-whitening products are in the high trend of demand for skin beautifying and lightening. Sources of ingredients for cosmetics could be natural, semi-synthetic, and synthetic that may affect the halal status of a product. The lack of scientific evidence on the safety and risks of such ingredients is a major concern to many consumers.

OBJECTIVE

This review paper aimed to shed light on the skin-whitening ingredients and their issues related to safety, health risk, and halal status.

METHODOLOGY

Based on the reviews scientific publications published from January 2015 to July 2020 using Web of Science and Scopus engines.

FINDINGS

Based on the review, most of the common ingredients in the skin-whitening products are originated from plants, animals, microbes, and heavy metals. Health risk of the ingredients was evaluated based on the usage, chronic or acute adverse effect, frequency of incidence, and the hazardous chemical contents of a halal cosmetics. The halal status of the ingredients was investigated based on the sources of origin, safety evaluation, and associated health risk of the ingredients.

ORIGINALITY

This review shows that ingredients play a vital role in the halal status decision-making of a cosmetic product. Therefore, the categories of Halal-Safe, Haram-Prohibited, and Critical-Need further evaluation were suggested to integrate the sources of ingredients with safety.

Usefulness of Artificial Membrane, Strat-M®, in the Assessment of Drug Permeation from Complex Vehicles in Finite Dose Conditions

The ban on the use of animals in testing cosmetic products has led to the development of animal-free in vitro methods. Strat-M^® is an artificial membrane engineered to mimic human skin and is recommended as a replacement for skin. However, its usefulness in the assessment of the permeation of cosmetics in in-use conditions remains unverified. No data have been published on its comparative performance with the membrane of choice, porcine skin. The comparative permeability characteristics of Strat-M^® and porcine skin were investigated using Franz diffusion cells. Caffeine (CF) and rhododendrol (RD) in complex vehicles with varying concentrations of polyols were applied as finite and infinite doses. Good rank orders of permeation from finite dose experiments were observed for RD. High correlations were observed in RD permeation between Strat-M^® and porcine skin under finite and infinite dose conditions, whereas only finite dose conditions for CF were associated with good correlations. Permeation from formulations with high polyol content and residual formulations was enhanced due to the disruption of the integrity of the Strat-M^® barrier. The usefulness of Strat-M^® in the assessment of dermal permeation may be limited to finite dose conditions and not applicable to infinite dose conditions or formulations applied in layers.
