Beauty is a big business. As an emerging economy, India is becoming increasingly important with the fast moving consumer goods (FMCG) market opening up, retail turning around and the Indian youth – men and women – becoming more experimental and discretionary concerning their approach to skincare.

Significant growth is being maintained in China’s cosmetics sector manufacturing base, and the need of Chinese formulators to acquire information about the latest developments with raw materials and ingredients was underlined by their strong attendance at the recently-held international Personal Care Ingredients Asia (PCIA) event recently held in Guangzhou.

The use of natural ingredients is an important trend shaping the personal care market. Consumers are enticed by multicultural, multi-benefit products that promise perceivable benefits to enhance their physical beauty. For cosmetic and personal care companies, new opportunities proliferate at the boundaries of traditional market segments where the one trillion US $ wellness market continues to expand at a rapid rate.

Modern hair treatments have to fulfill not only technical requirements but also high emotional demands. While data on combing work, tensile strength or fatigue testing are common to support technical claims, the market success of a product is essentially determined by fulfilling those emotional characteristics which are claimed in the advertisement.

Formulations having an acidic pH, (i.e. pH <6.0), containing cationic components, such as cationic surfactants and salts thereof or active acidic components are commonly referred to as “low pH” formulations. These ingredients are commonly chosen for formulations used to treat or condition the hair and skin and can be found in shampoos and cleansing products, creams and lotions, and gels.

The use of tensor active ingredients in anti-age care products is well-known to provide the users with immediate and visible effects. Nevertheless, these tensor active ingredients provide only mechanical effects on the skin surface that are also short-term effects. In order to extend the tightening active ingredient offer, Silab has searched for an innovative and complementary approach of immediate and mechanical tensor ingredient using its expertise in both skin biology and tightening active ingredient fields.

Studies conducted on personal care products in the 1960s and 1970s found up to 24% of unopened products were contaminated, mainly with Pseudomonas, while up to 49% of used samples were also contaminated. These studies highlighted the need for the incorporation of preservatives into water-based formulations along with improvements to manufacturing practices.

Cosmetic formulators throughout the world are increasingly facing diverse demands from their customers, marketing managers, and other interested parties. Formulators are expected to deliver products with increasingly sophisticated performance, while also making use of more and more naturally derived ingredients to satisfy expectations for health, safety, and environmental responsibility. This creates a formidable challenge to raw material suppliers to the personal care industry – to develop new naturally derived ingredients that cost-effectively deliver outstanding performance benefits in complex finished goods.

Mention the word “naturals” and the first thought that comes into many minds would be plants, botanicals and herbal materials. The next thought would probably be essential oils and after a little more deliberation the idea of honey, seaweeds and sea salts would form. However, there are many interesting materials that do not grow in the soil but are a part of the geology. It was felt that a review of the use of minerals, earths, metals, semi-precious stones and gems in personal care products might be useful.

Rheology modifiers are no longer expected to just thicken, suspend and stabilise formulations. They must also function over a broad pH range and be compatible with a variety of ingredients. Ideally, rheology modifiers are also expected to deliver consumer perceivable benefits to personal care formulations, while still delivering superior aesthetic properties including clarity in aqueous solutions.

There is no doubt that all kinds of microorganisms are widely spread around us. Microorganisms exist in used or unused cosmetic and personal care products, and the common forms of microorganisms are bacteria (either gram positive or gram negative), mould, and yeast. Some microbes are harmless, but some, such as Staphylococcus aureus, Pseudomonas aeruginosa, are greatly harmful to human beings. The need for preservatives in cosmetic and personal care products is to protect the consumer from contaminated products, i.e. to protect the product from microbial contamination.
