... Silicones are widely used nowadays in every cosmetic formulation. Research is also being carried out to improve the use of silicones like a research work conducted in 2018 developed a hair care formulation containing silicones and vegetable oil, and the results showed that silicones helped in the treatment of hair fibres and made hair softer [31]. ...
Cosmetics, a captivating category of over-the-counter products that enhance appearance and promote skin health, have become ubiquitous in modern society. Initially associated with altering one’s appearance, cosmetics have evolved beyond their traditional beauty role to encompass skincare and the treatment of various skin conditions. While numerous chemicals can be utilised in cosmetic formulations, key ingredients include water, emollients, humectants, surfactants, preservatives, antioxidants and ultraviolet (UV) filters. With the rise in consumer preferences for clean beauty, silicone- and paraben-free cosmetics and cruelty-free testing, safe and effective herbal and plant-based products have gained significance. Researchers are actively exploring the development of natural cosmetics, leveraging the synergistic properties of these substances. Nanoformulations such as liposomes, nanoparticles and emulsions have been investigated and proven safer and more efficient than conventional cosmetics. This chapter provides a comprehensive overview of the utilisation of these ingredients in cosmetics, their specific effects on product development and properties, emerging alternatives in the personal care market, the widespread adoption of nanotechnology in various scientific fields, and its impact on the advancement of personal care products.

... Many examples of liquid, semi-solid and solid topical drugs are described throughout the scientific literature. Silicone excipients have been incorporated in some liquid preparations such as emulsions , solutions (Kalari et al., 2019) and dispersions used as lotions (Burgess et al., 2017), shampoos (Leite and Maia, 2018) or sprays (Moortgat et al., 2019). They are also present in semi-solid preparations such as gels (Li et al., 2018;Stewart et al., 2016;Wiseman et al., 2017), creams (Kalasho et al., 2019;Zoumalan et al., 2019) and ointments. ...
Silicones, more specifically those of the polydimethylsiloxane type, have been widely used in the pharmaceutical industry for decades, particularly in topical applications. In the dermatological field, in addition to provide undeniable textural and sensory benefits, they can play important functions in the physicochemical properties, stability and biopharmaceutical behavior of these formulations. However, despite the notable advances that can be attributed to the family of silicones, the reputation of these compounds is quite bad. Indeed, silicones, even if they derive from sand, are synthetic compounds. Moreover, they are not biodegradable. They flow into our wastewater and oceans, accumulating in the fauna and flora. This obviously raises many concerns in the common imagination. Do silicones represent a danger for our environment? Should the human species worry about long term toxic effects? Are the claimed benefits really that important? After exploring the various applications of silicone excipients in topical dermatological formulations with a special focus on recent advances which open breathtaking prospects for dermatological applications, this paper shed light on the specific challenges involved in preparation of silicone-based drug as well as, the in vivo behavior of these polymers, the toxicological and environmental risks associated with their application.

The mitigation of damaged hair conditions involves the application and penetration of substances to stabilize broken bond sites, restore lipids and proteins, reinstate hydrophobicity, and recover hair mechanical properties. Vegetable oils, in general, exhibit a list of advantageous characteristics much desired by consumers, given the associated benefits for hair fibers. While coconut oil is highly popular in the hair care market and extensively studied for its ability to diffuse through the hair cortex, the effects of avocado and argan oil on the internal structure of hair and their potential benefits remain underexplored. Tensile and fatigue tests, as well as Raman spectroscopy, were carried out to investigate the interaction of these three oils with virgin and bleached Caucasian hair. The oils were applied in sufficient amounts directly to hair tresses and maintained for 24 h at 25 °C. Our results show that the three oils successfully diffused and interacted with the cortical region of the hairs. Their impact on hair mechanical properties depends on the level of damage and humidity conditions. In virgin hair, coconut and avocado oil reinforce the hydrophobic barrier of the cellular membrane complex, preventing water from causing intense perturbation of the mechanical properties, leading to increased stiffness and break stress. Meanwhile, due to the high degree of unsaturation of its fatty acid chains, argan oil increases water absorption, resulting in losses in hair resistance. When bleached, the hydrophilicity of the hair fiber increases, determining more affinity for argan oil. Consequently, the affinity with water is also elevated, causing increased fragility to mechanical stress. The analyzed vegetable oils are not always beneficial for hair care. Their specific chemical characteristics and hair conditions will influence the final results and should be taken into consideration in hair care product development.
Objective
With the constant upgrading of healthcare concepts, silicone‐free hair products have attracted more attention among consumers. In the present study, transparent silicone‐free shampoo containing proteins was successfully fabricated by mixing of mild non‐sulfate surfactants, compound cationic conditioners, natural silicone oil substitutes, protein conditioners, thickeners and other auxiliary ingredients. Effects of the type of surfactants, hair conditioners and thickeners, the type and content of proteins, and mass ratio of compound proteins on the hair foaming performance, hair grooming performance and penetration performance were investigated.
Methods
The basic formulation framework of transparent silicone‐free shampoo was established at first. Then, various hydrolyzed proteins were further added to the basic formulation in the form of single use or compound use to prepare transparent silicone‐free shampoo containing different proteins. The morphology of hair samples and penetration of protein in hair was evaluated with a scanning electron microscope and a laser confocal fluorescence microscopy, respectively. And the hair grooming performance was also determined by a dynamic combing tester.
Results
The compound proteins of Croquat WKP PE‐LQ‐WD and Gluadin® Kera‐PLM with the mass ratio of 1:9 and 1:1 at 2 wt% total content of proteins added into the silicone‐free shampoo brought higher contact angle and lower frictional coefficient than commercial silicone‐free shampoo without proteins. In addition, the compound proteins also have the dual effect of adsorbing the hair surface and penetrating deep into the interior of the hair.
Conclusion
The combination of cationic modified hydrolyzed protein (e.g., Croquat WKP PE‐LQ‐WD) and hydrolyzed protein with low molecular weight (e.g., Gluadin® Kera‐P LM) at appropriate mass ratio exhibited a strong synergistic effect of hair conditioning properties. It could provide a significant reference for developing silicone‐free hair products with more benefits.
