Beck, R. published the artcilePhase behaviour and physical properties of mixtures of calcium salts of α-sulfonated fatty acid methyl ester and a cosurfactant, Application of 3-((2-Ethylhexyl)oxy)propane-1,2-diol, the publication is Physical Chemistry Chemical Physics (2001), 3(24), 5438-5443, database is CAplus.

We have studied the phase behavior of mixtures of calcium salts of α-sulfonated fatty acid Me ester Ca(C_x-α-MES)₂ and a monoglycerin ether as cosurfactant (EHG). The mol. interactions between the surfactant and the cosurfactant and the influence on the phase behavior have been studied systematically. With increasing cosurfactant concentration the micellar L₁-phase shows a transition to an L_α-phase and an L₃ sponge phase. The L₃-phase is observed for the first time in a ternary phase diagram of a Ca-salt of a α-sulfonated fatty acid Me ester, the cosurfactant 2-ethylhexyl-monoglyceride and water. As for other ternary surfactant/cosurfactant systems, the L₃-phase occurs with increasing cosurfactant/surfactant ratios after the L_α-phase. Some properties of the newly observed L₃-phase are the same as for other known L₃-phases. It is a low viscosity, optically isotropic fluid with a low flow birefringence. The time constants τ of the elec. birefringence results scale with τ ∼ Φ^-3. Its conductivity is very much higher than the conductivity of the neighboring L_α-phase. However there are some marked differences from known normal L₃-phases. The novel L₃-phase is thermodynamically stable in spite of ionic charges on the bilayer. There is no two phase region between the L_α and the L₃-phase in the system Ca(C₁₄-αMES)₂/EHG and the L₃-phase is stable over a wide cosurfactant/surfactant ratio between one and two. In SANS measurements it shows a broad correlation peak that occurs at about the same position as the sharper peak in the L_α-phase. The structure of the L₃-phase is demonstrated by FF-TEM micrographs.

Ihndris, Ray W. published the artcileEffect of promising insect repellents on plastics and paints, Related Products of alcohols-buliding-blocks, the publication is United States, Agricultural Research Service, [Report] ARS (1955), 27 pp., database is CAplus.

Action of 380 repellents on Lucite, cellulose acetate, and Vinylite after 48 h. of contact are tabulated (studies in 1946). Sixty-eight of the compounds did not change any of the plastics. Lucite was attacked by 261, cellulose acetate by 126, and Vinylite by 251. Only 99 compounds attacked all 3. Results of studies in 1953 are shown in a tabulation of effects on paint, Plexiglas, Vinylite, rayon, and Plastocel of 136 repellents which had not proved unsatisfactory since 1946 for some other reason. All but 2 compounds affected paint; one of them, octyl crotonate, affected only varnish and vinylite, and the other, 3,6,8-trimethyl-4-nonyne-3-6-diol affected only varnish. Vinylite was damaged by 107, Plexiglas by 58, rayon by 55, and Plasticel by 46. In other tests only 2 chems., 2-benzyloxynaphthalene and 2-iso-pentyloxynaphthalene, affected polyethylene, and they only slightly. Fourteen materials slightly stained nylon. In still other tests, Lucite and Plexiglas were found to differ slightly in their resistance to various agents.

Salama, Paul published the artcileThe use of catalytic amounts of selected cationic surfactants in the design of new synergistic preservative solutions, Recommanded Product: 3-((2-Ethylhexyl)oxy)propane-1,2-diol, the publication is Cosmetics (2021), 8(2), 54, database is CAplus.

Preservation using combinations of antibacterial mols. has several advantages, such as reducing the level of usage and broadening their antimicrobial spectrum. More specifically, the use of quaternary ammonium surfactants (QAS)-which are profusely used in hair care products and some are known as efficient antimicrobial agents-is limited due to some potential cytotoxicity concerns. This study shows that the concentration of some widely used cosmetic preservatives can be decreased when combined with very small quantities of QAS, i.e., Polyquaternium-80 (P-80) and/or Didecyldimethylammonium chloride (DDAC). The antimicrobial activity of their mixtures was first evaluated by determining the min. inhibitory concentration (MIC) before and after the addition of QAS. Following up on this finding and targeting an ultimate consumer friendly antimicrobial blend, yet with optimal safety, we chose to utilize the food-grade preservative Maltol as the main natural origin antimicrobial agent mixed with min. concentrations of QAS to improve its moderate antimicrobial properties. The preservatives were tested for MIC values, challenge tests and synergy using the fractional inhibitory concentration index (FICI). The antimicrobial efficacy of Maltol was found to be synergistically improved by introducing catalytic amounts of P-80 and/or DDAC.

Salama, Paul published the artcileWhy Are Wet Wipes So Difficult to Preserve Understanding the Intrinsic Causes, Category: alcohols-buliding-blocks, the publication is Cosmetics (2021), 8(3), 73, database is CAplus.

Over the last two decades, significant advances have been made in developing disposable baby wet wipes. Wet wipes consist of two main components: nonwoven fabric and liquid Being more than 90% water, wet wipes are more susceptible to microbial growth than typical personal care products; hence, high concentrations of preservative compounds are often used to ensure extended protection against contamination. However, there is an obvious tendency to minimize the concentration of irritating actives. Baby wet wipes should contain particularly mild surfactants, well-tolerated preservatives, and a buffer system maintaining the formulation pH at a suitable level for the infant’s skin. Efforts have been centered on removing ingredients with irritation potential, such as phenoxyethanol. In addition, a move towards more natural fabrics is occurring. However, these modifications provoke new challenges in preserving the final products. The nature and composition of the fiber can influence the interactions between the preservative and the wipe, subsequently affecting the performance of the preservative system. In this study, we analyzed the causes of the challenge in preserving wet wipes. We found that fabrics containing natural fibers are the main source of contamination, promoting the generation of biofilms on their surfaces. Moreover, the hydrophilic-lipophilic balance (HLB) was utilized to rationalize the physicochem. interactions between the fabric and the preservatives.

The goals of this paper are the comparison of different methods for the determination of solubility, the presentation of some examples of solubility data for solid UV absorbers, and the introduction of a concept using this knowledge to create light feel formulations. UV filters are the key ingredients necessary for the efficacy of sunscreens. Most of the organic UV absorbers are oil-soluble or even oil-miscible compounds and consequently are incorporated into the oil-phase of sunscreen emulsions.

Facial allergic contact dermatitis caused by cosmetic products is common. New allergens in cosmetics continuously emerge. To investigate characteristics of patients with facial dermatitis (FD) between 2010 and 2019 including patch test results from cosmetic-related allergens and a new test series with cosmetic-relevant natural ingredients (CRNIs). This is a retrospective study analyzing demographics, clin. characteristics according to MOAHLFA index (male; occupation; atopic dermatitis; hand; leg; face; age ≥ 40 years), and patch test results to 27 cosmetic-relevant allergens in FD patients. A prospective study evaluating a screening test series with CRNIs in consecutive FD patients for 1 yr was also conducted. These patients received a questionnaire for collecting extra characteristics (eg, concerning quality of life). Of 8740 tested patients, 2292 (26.2%) had FD. Of these, 30.6% had cosmetic-induced FD. The most common cosmetic-related allergens were fragrances and preservatives. The most common patch test-pos. CRNIs were hydroperoxides of limonene and linalool, and propolis. Potato and peanut were rare, but the most common prick test-pos. CRNIs, however, without any relation to the use of cosmetic products. FD affected nearly all patients′ quality of life and caused limitations to their daily life. Updated management and quick diagnosis of FD is important to avoid neg. impact on patients′ quality of life.

Perales, Eduardo published the artcileEcotoxicity and QSAR studies of glycerol ethers in Daphnia magna, Name: 3-((2-Ethylhexyl)oxy)propane-1,2-diol, the publication is Chemosphere (2017), 277-285, database is CAplus and MEDLINE.

Glycerol is currently considered a raw, renewable material, which can be used to synthesize new glycerol derivatives that may be used as green solvents. However, these compounds must be environmentally evaluated before their use. The acute ecotoxicity of a series of mono-, di-, and trialkyl ethers synthesized from glycerol for the crustacean Daphnia magna has been studied. The EC₅₀ values of these ethers after 24 h of exposure were determined according to the OECD 202 protocol. Their possible structural-toxicity relationships according to different alkyl substituents have been discussed after applying different QSAR models (with the DARC-PELCO approach and topol. parameters). The results of the immobilization test show that most of the glycerol derivatives studied exhibit relatively low ecotoxicity. There is a correlation between the lipophilicity and the increase of the toxic effect in the crustacean biomodel. Furthermore, the length and the number of the alkyl substituents and ecotoxicity are highly related.

Martins, Marcia S. published the artcileOccurrence of Allergens in Cosmetics for Sensitive Skin, Formula: C11H24O3, the publication is Cosmetics (2022), 9(2), 32, database is CAplus.

Sensitive skin is characterized by symptoms such as stinging and tingling in response to stimuli that usually do not cause unpleasant sensations. Epidemiol. studies show that individuals with sensitive skin are more prone to developing skin allergies, although the link between both conditions is unknown. Aiming to evaluate the presence of allergens in facial-skin products for sensitive skin, a pool of 88 cosmetic products from international brands marketed in pharmacies and parapharmacies was analyzed. A list of allergens identified in product labels was compiled and grouped according to their function. Fragrances were the most common allergens, followed by skin-conditioning agents, surfactants, and preservatives. Fragrances presenting the highest use percentages were linalool, benzyl alc., geraniol, and citronellol. Overall, the majority of cosmetic formulations were absent of fragrance allergens, being present only in 7% of products. Other allergens were found in most products (95%). This finding should be interpreted with caution, since many of these compounds are rare sensitizers and studies demonstrating their risk for individuals with sensitive skin are lacking. With this study, useful information for health professionals is provided to support their advice and to help consumers choosing cosmetic products.

A review. Despite the promising results of preliminary studies and hope for preventing atopic dermatitis (AD) and food allergy (FA) in high-risk infants by emollient application from their first days of life, further analyses failed to confirm the validity of such an approach. Haptens are low-mol.-weight chems. that may cause irritant or allergic contact dermatitis or subclin. skin barrier function changes. In 13 of the 17 emollients, at least 1 hapten was identified. The haptens found in the preparations were as follows: lanolin, iso-Pr myristate, phenoxyethanol, benzyl alc., sorbitan oleate, sorbitan sesquioleate, tocopheryl acetate, tocopherol, sorbic acid, propylene glycol, panthenol, ethylhexyl glycerin, cetearyl alc., cetyl alc., and stearyl alc. Thus, it is possible that chronic use of moisturizers containing haptens may lead to a vicious cycle of inflammation and skin barrier disruption that requires repeated applications of products
