With over 200 international exhibitors, scientific conference papers, in-depth technical workshops and free presentations PCIA deals with all the major issues and developments in the personal care market. In 10 years, the event has grown to become the largest, most important personal care event in the Asia Pacific region.

Assessing a factory to see whether it is suitable for manufacture of cosmetics and toiletries is a vital and important part of any client’s responsibilities, especially if intending to export to a foreign market like Europe.

UV radiation can be harmful to the skin. UVB radiation has an immediate effect of causing erythema, while UVA radiation is suspected of causing long-term damage (loss of elasticity of the skin) and possibly melanoma. In addition to sunscreen products, many other personal care products have been incorporating UV actives to mitigate this damage.

Anew generation of cationic conditioning polymers (Polyquaternium-67) has been engineered. Polyquaternium-67 (PQ-67) is a family of high viscosity quaternised hydroxyethyl cellulose (HEC) polymers with cationic substitution of trimethyl ammonium and dimethyldodecyl ammonium. These novel polymers were found to provide enhanced aesthetic feel and good compatibility with surfactant systems without the complication of associative thickening.

Personal Care Ingredients Asia (PCIA) is well established as a “must visit” event and consistently attracts large attendances. From the inaugural show in Malaysia in 1997, PCIA has had an ever-growing reputation for bringing together formulators, specialists in personal care product manufacturing, and suppliers of raw materials and ingredients.

Be it Asia, Europe or United States, the search for alternatives to conventional preservatives is a big concern. Personal care companies are searching for alternatives to parabens and paraben blends, formaldehyde donors and isothiazolinones, just to mention a few. They are looking for broad spectrum, cost effectiveness, safer, naturally derived, label friendly, more global acceptance alternatives while at the same time being able to say preservative free.

During the last decade there has been an increase in consumer awareness with regard to chemicals used in everyday life. To this effect the pressure from consumers, pressure groups, media institutions and governments around the world has increased significantly on the safety of certain groups of raw materials used in personal care and cosmetic formulations. Fragrances, dyes, preservatives, surfactants and even naturally derived materials such as those of the tea tree have come under scrutiny or so-called attack. The evolving technology and techniques now employed in evaluating the toxicology of existing materials means that the safety of many raw materials is being scrutinised, reassessed and in some cases banned from use by regulatory and safety authorities.

It is now clear that Personal Care & Household Ingredients China (PCHi) will provide unrivalled opportunities for information gathering and networking. The new exhibition and conference has been designed to meet the requirements of the rapidly-growing market in China for personal care and household products. The first PCHi is being held at Intex, Shanghai, on 18, 19 and 20 October 2005.

Natural preservation is one of the most popular topics in the industry and attracts the attention of even the most traditional of formulating chemists. This article looks at the theoretical development of a natural preservative system. The traditional methods of preservation, many taken from the food industry are summarised and the latest raw materials on offer within the industry are evaluated.

Regulations for preservatives incorporated into cosmetic and other personal care products vary between the USA, Europe and Japan – listed here are regulations for Japan. Japanese colour regulations were featured in the May 2005 edition of Personal Care, and details of sunscreen regulations applying in Japan, the USA and the European Union were provided in the July 2005 edition of the magazine.

Marine brown algae could play an important role in the cellular metabolism thanks to specific sugars and polyols naturally produced or induced after stress.

Unlike past conferences, ASCS 2007, the 8th Conference of the Asian Societies of Cosmetic Scientists, offers delegates a unique opportunity.

In recent years, there has been a growing demand for a means to suppress sebum secretion and keep skin clean in young people, and exert anti-ageing effects in adults, as well as to suppress body odour in people of all ages.
