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.

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.

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.

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.

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.

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.

Market trends are driving the development of polymer and surfactant ingredients toward natural origins—in particular, plants. In this article, the authors review some of the recent trends in green surfactants and polymers for hair care. One interesting technology transfer trend is the use of hydrogen-bonded supramolecular networks to produce self-healing fixative films.

Delivering Actives via Solid Lipid Nanoparticles and Nanostructured Lipid Carriers: Part II, Nanoparticle Characterization
By: Johann W. Wiechers, PhD, JW Solutions; and Eli…
Part I of this review on Solid Lipid Nanoparticles (SLNs) and Nanostructured Lipid Carriers (NLCs) as delivery systems for cosmetic actives appeared in the October 2010 issue of Cosmetics & Toiletries magazine. Part II, presented here, describes how to characterize SLNs and NLCs; part III, in March 2012, will discuss the stability and occlusion properties of actives and liquids in SLNs and NLCs, and examine their efficacy. Finally, part IV, in May 2012, will discuss the use of SLNs and NLCs in cosmetic products.

Guar hydroxypropyltrimonium chloride (GHPTC) is one of the most widely used cationic polymers in the personal care industry. GHTPC is employed primarily as a conditioning agent in shampoos and body washes. In many of these rinse-off products, it is also a critical deposition aid for the delivery of active ingredients and hydrophobic conditioning agents, e.g., silicones, to the skin and hair.
