A Sunscreen Formulation for Acne-prone Skin

This article describes the study of a topical sunscreen formulation that contains titanium dioxide and ethylhexyl methoxycinnamate for UV protection, and phosphatidylcholine and hydrosoluble azelaic acid for acne control.

Hyperbranched Polyalphaolefins Enhance Anhydrous Stick Formulations

Hyperbranched polyalphaolefins offer distinctive functional and aesthetic properties due to their branch-on-branch configuration. In anhydrous stick formulations containing polyethylene or other crystalline waxes, the addition of hyperbranched polyalphaolefins is shown in this article to lower pour points by as much as 10C, increase gloss, modify structure and improve formula stability.

Research Pathways to Photostable Sunscreens

This article provides a visual depiction of pathways that UV filters undergo when exposed to solar radiation; such pathways often lead to photo-instability. A fluorescence technique is described that has led the author to identify compounds that preserve photostability in a novel manner­— by quenching the UV filter’s singlet excited state.

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.
