“…Surfactants could effectively reduce the surface tension of the liquid and the surface energy of the pores, allowing for the half-life of the aqueous foam to be extended. Al-Qararah et al (2015) and Hou and Wang (2017) obtained similar results and noted that pore size and distribution were also affected by surfactants. Guan and Hanna (2004) reported that the formaldehyde could increase the degree of acetal to increase the number of hexagonal/ pentagonal-shaped ring which could strengthen the structure of modified PVFM and reduced the escape of pores during the acetal process.…”

Fresh fruits are very susceptible to mechanical damage during harvesting, packaging, and transportation, which can substantially reduce their quality and lead to a loss in profits (Li & Thomas, 2014).The requirements of fruit packaging materials have greatly increased with the development of e-commerce and the logistical operations involved in their handling, packaging, storage, and transportation.Vibration-damping materials could reduce fruit mechanical damage and protect fruit appearance and quality (Singh & Reddy, 2006).Mechanical damage to fruits can cause biochemical changes such as membrane lipid damage and can lead to increased ethylene production and respiration. These changes can increase browning, rot and, quality deterioration of fruits (Ahmadi et al., 2010;Li & Thomas, 2014). Dhital et al. (2017 believed that mechanical damage during transportation and harvesting was one of the major causes of fruit rot. Therefore, the

“…Polyvinyl alcohol as a foaming agent represents a polymeric surface-active chemical, and the desired foaming ability of the PVOH with a similar degree of hydrolysis (DH) in the presence of CNF has been previously demonstrated by Hou and Wang (2017) [ 35 ]. PVOH is not only efficiently generating CNF containing foams but can also improve bonding strength of individual fibrils [ 36 ].…”

Enhancing the Stability of Aqueous Dispersions and Foams Comprising Cellulose Nanofibrils (CNF) with CaCO3 Particles

In this work, stability of dispersions and foams containing CaCO3-based pigments and cellulose nanofibrils (CNF) was evaluated with the aim to reveal the mechanisms contributing to the overall stability of the selected systems. The utmost interest lies in the recently developed hydrocolloid hybrid CaCO3 pigments and their potential to form bionanocomposite structures when incorporated with CNF. These pigments possess a polyelectrolyte layer deposited on the surface of the particle which is expected to enhance the compatibility between inorganic and organic components. Stability assessment of both dispersions and foams was conducted using turbidity profile scanning. In dispersions, CNF provides stability due to its ability to form a firm percolation network. If surface-modified pigments are introduced, the favourable surface interactions between the pigments and CNF positively influence the stability behaviour and even large macro-size pigments do not interfere with the stability of either dispersions or foams. In foams, the stability can be enhanced due to the synergistic actions brought by CNF and particles with suitable size, shape and wetting characteristics resulting in a condition where the stability mechanism is defined by the formation of a continuous plateau border incorporating a CNF network which is able to trap the inorganic particles uniformly.

“…Methyl paraben is effective over a wide pH range and has a broad spectrum of antimicrobial activity [14]. In the manufacture of peel-off gel mask preparations at the stirring stage with a homogenizer, PVA undergoes foaming because DOI 10.18502/kme.v2i3.11886 ICMEDH PVA itself can be foam forming which can increase the mass of the peel-off gel mask [15]. Because of this, an additive is needed as an anti-foaming, namely dimethicone.…”

The main cause of premature aging of the skin is the presence of free radicals which are created by UV rays. The use of antioxidants is a promising option for overcoming these problems. Duwet (Syzygium cumini) is a natural source of antioxidants. A peel-off mask is a cosmetic product which forms an easy to peel-off layer on the skin’s surface. This study aimed to determine the physicochemical characteristics, antioxidant activity, irritation effect, and stability of duwet leaf extract peel-off mask preparations. Duwet leaf extract was macerated by a methanol solvent and formulated into the peel-off masks with a concentration of 1%, 3%, and 5%. The results showed that the preparation produced good characteristics with a drying time of fewer than 30 minutes and showed significant antioxidant activity with the highest inhibition in the preparation with 3% duwet leaf extract. This preparation also had no irritating effect on CAM and was stable during storage using freeze-thaw and real-time methods. It can be concluded that duwet leaf extract can be used as an active agent for anti-aging peel-off masks.
