Tetrapeptide Targets Epidermis Cohesion

Most antiaging products claim to act on the dermis; however, the epidermis, a key element of cutaneous aging, is often forgotten. In the present study, researchers selected an acetylated tetrapeptide for its effect on epidermis cohesion, triggered by activity on syndecan-1 and collagen XVII; these effects are confirmed in vivo.

Grapefruit Extract Cream: Effects on Melanin in Skin

The current work aimed to formulate a stable w/o emulsion containing grapefruit extract by entrapping the extract in the inner aqueous phase. The final formula was found to have skin-whitening, moisturizing, cleansing and antiwrinkle effects, among others.

Profile of Ascorbic Acid

L-Ascorbic acid (AscA), more commonly referred to as vitamin C, is best known for its vital role in human health and nutrition, where it functions as a cofactor in enzymatic reactions, such as collagen synthesis, and as an antioxidant.

Symrise Launches Multifunctional Stabilizer

Symrise has introduced a multifunctional stabilizer for cosmetics that also exhibits antioxidant, soothing and preservative boosting functions.

Worlée Launches Castor Oil Alternative to PE and PP Exfoliants

Worlée has launched natural exfoliant beads as alternatives to plastic microparticles (PE and PP).

Vegetal-derived Emulsifiers for Improved Stability and Formula Efficiency

The quest for PEG-free surfactants and emulsifiers has led to new classes of vegetal-derived, ethylene oxide-free ingredients for environmentally friendly personal care products. Two such ingredients, described here, are based on the combination of olive oil and vegetable proteins with the first derived from oat and the second, with glutamic acid. These materials provide mildness and skin protection benefits.

Improving Tactile Properties of Vegetable Oils with Vegetable Oil-based Esters

Vegetable oil-based esters are shown by the authors to improve the tactile attributes of vegetable oil by lowering its viscosity and improving its spreadability, in addition to providing environmentally friendly options for cosmetic chemists.

Hand Sanitizer Actives: A Review

Hand sanitizing is a proven public health benefit that has grown globally. While alcohol is the most tested and proven active used for hand sanitizing, other actives are employed, including quats, triclosan and natural antimicrobials. Here, the authors review the benefits and limitations of various hand sanitizer actives.

Feasibility Study of Sago Starch for Perfumed and Cooling Body Powders

In the present article, sago starch-containing perfumed and cooling body powders are formulated and their physicochemical properties for potential skin irritation are examined. The results indicate that sago starch could potentially be used as the main component in body powders.

A Micro-wax Dispersion to Condition Hair and Reduce Breakage

Here, a micro-wax dispersion is shown to provide conditioning and anti-hair breakage properties. The authors incorporated the material into test shampoos, compared them with two silicone-based benchmarks, and found the micro-wax shampoos provided comparable conditioning and improved hair breakage prevention performance. Results were confirmed in a hair washing test.

Understanding Fragrance in Personal Care

Fragrances often are used in personal care products to affect the consumer’s perception of product performance. Therefore, product formulators must be cognizant of their target audience, as well as aware of fragrance allergens, approved fragrance materials and interactions between fragrances and other ingredients. The present article provides an overview of these factors.

Cooking Chemistry and the Formulator—Seasonings: Taste and Smell

This article is the last in a four-part series that highlights connections between cooking chemistry and personal care product development, including reactions that occur and why, and how to best utilize these reactions, for the benefit of formulators.
