Moisturizers are used on all skin types to address a range of skin issues/needs. Main uses include: prevention in normal and dry skin, healing of irritated skin and treatment of diseased skin. It is difficult to clinically study the efficacy of moisturizers in a meaningful way.

Polyquaternium-74 is a synthetic high performance conditioning polymer whose flocculation and deposition characteristics enable it to match or outperform traditional conditioning polymers in detangling, overall hair conditioning, shine enhancement and buildup reduction when combined, as shown here, with a submicron dimethicone emulsion. Benefits are noted for 2-in-1 shampoo formulations.

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.

Glycerin is a unique and versatile chemical with numerous applications; to adequately cover all of the aspects of this compound in a short column would be impossible. Therefore, this column will highlight some key facts about glycerin, but interested readers are encouraged to pursue further, more comprehensive reading on the ingredient.

While humectants and occlusive agents are the most commonly accepted approaches to moisturize skin, earlier work indicates a third approach: orthorhombic phase stabilization. In the present article, the author describes this novel mechanism of hydration and its detection by conventional and nonconventional methods, suggesting this approach could serve as a basis for all skin moisturizing therapies.

In the present article, a renewable ingredient microemulsion is formulated that is free from ethoxylates and sulfate groups. Used as an additive, the material boosts the conditioning performance of shampoos and improves wet-combing performance by affecting phase separation. In addition, base formulas for standard and “green” shampoos are discussed.

Last month’s “Ingredient Profile” column reviewed polyquaternium-6 (PQ-6), the cationic homopolymer of diallyldimethylammonium chloride (DADMAC). In relation, this month’s column examines its cousin, polyquaternium-7 (PQ-7), one of the most widely used and cost-effective conditioning polymers for personal care applications.

Hydrolyzed jojoba esters were incorporated into formulas including a lotion, hand sanitizer and nonwoven wipes. Small, well-controlled clinical studies were then conducted to compare the formulas with or without glycerin. Results show the esters can potentiate the skin moisturizing effect of glycerin under varying formula conditions. A mechanism of action also is discussed.

Moisturization in skin care formulations requires an understanding of clinical needs, relevant biological targets and the aesthetic preferences of consumers. The efficacy of moisturizers must be established in vivo due to consumer interest in both visual and instrumental validation. This review outlines the challenges of formulating moisturizing facial skin care products in line with such principles.

In the present article, a topical emulsifier blend comprising two sucrose esters at low use levels and one solid fatty alcohol is described. This composition was designed to make the use of sucrose esters in formulations more cost-effective. The blend is shown to form multilamellar liquid crystalline networks for various benefits including skin moisturization, which is assessed here.
