Formulating Focus—Delivering Actives via Solid Lipid Nanoparticles and Nanostructured Lipid Carriers: Part III, Stability and Efficacy
By: Johann W. Wiechers, PhD, JW Solutions; and Eli…
Part I of this review on Solid Lipid Nanoparticles (SLNs) and Nanostructured Lipid Carriers (NLCs) discussed the differences of these two delivery systems for cosmetic actives, as well as their production methods and selection criteria for constituents. In Part II, the characterization of these nano-sized particles was considered. In Part III, presented here, their stability and efficacy are considered; Part IV will address their application in cosmetics.

Formula Troubleshooting—Stability, Uniformity in Foundations
By: Peter Tsolis and John Castro, The Estée Lauder…
Although any formulation type can pose obstacles for the cosmetic chemist, foundations are notorious for their degree of difficulty and intricacy of detail. As if it were not challenging enough to stabilize emulsions with superior aesthetics, foundations require emulsion stability while ensuring color properly develops and stays uniform throughout the product.

Formula Anatomy Deciphered—Color Foundations and Bases
By: Luigi Rigano, Rigano Industrial Consulting Lab…
The category of color cosmetics referred to as foundations, also known as bases, strives to achieve a complex mix of functional, sensorial and aesthetic effects. These all-over facial cosmetics aim to hide minor skin imperfections like wrinkles and blemishes; to even and modify the skin color of the face; and to alter the light reflection capability and luminosity of the face and neck—all while maintaining a natural-looking and velvety appearance.

Gauging UV Light Exposure to Reduce Vitamin D Deficiency
By: Jack Surrette, SkinHealth Technology LLC
Vitamin D is critical to human health and the best source is from natural UVB light. However, contrary to the benefits gained are the well-documented damaging effects of sun exposure. In response, described here as a complementary approach to sun care is the development of an accurate gauge of UV exposure to produce optimum levels of vitamin D before sunburn results.

Developing Sunscreens for the Preventive Treatment of Photodamage and Premature Aging
By: Linda D. Rhein, PhD Fairleigh Dickinson Unive…
This article reviews the mechanisms of ultraviolet radiation insult to skin and explains the formulation of sunscreens to protect against this damage. Further, since the efficacy of combinations of UV filters will vary with formulation base, the formula vehicle and form are discussed, as well as an overview given of typical sunscreen efficacy tests performed prior to production.

Formulating With Naturals—Antiperspirants and Deodorants
By: Arthur Georgalas, Georgalas Endeavors
Within the realm of natural and organic personal care products, deodorants and antiperspirants loom large simply because the overall category itself is very large in any retail health and beauty aids planogram. These two related products—i.e., antiperspirants and deodorants (AP/Deo)—are fraternal twins joined at the axilla that perform in this same anatomical arena using some of the same tricks.

Hair Color Vibrance Factor to Characterize Shine and Color Intensity*
By: Timothy Gao, PhD; Peter Landa; Regan Tillou; a…
To evaluate the comprehensive effects of shine and color intensity in hair, a hair color vibrance factor has been developed to enable new claims for hair dye formulas and after-dye treatments. Experimental results described here show how varying the ingredients in shine spray and hair dye formulas affect this factor and correlate with subjective panelist assessments.

Repairing Hair with Natural Actives
By: Jean-Christophe Choulot, PhD ALES Group
The present article reviews the structure of hair and various types of hair damage, demonstrating that repair treatments must intervene at several levels within hair. While film-forming agents are often used, they slow or prevent the penetration of actives. A hair serum including natural actives and omitting these film-formers was thus formulated and tested for its repair capabilities.
