Production of Cosmetic
Creams and Lotions

Manufacture of Deodorants
and Antiperspirants
A deodorant stops odor by killing skin bacteria with biocides and masking odor through fragrance. An antiperspirant reduces the amount of available water on the skin with astringents, most commonly aluminum salts. Both types of product are generally water in oil or water in silicone emulsions, containing active ingredients (biocides or aluminium salts), emulsifiers, gelling, suspending or thickening agents, waxes, emollients, preservatives, colorants and fragrance. |

Dilution of High Active Surfacants
Surfactants such as Sodium Laureth Sulphate (SLES) are widely used in shampoo, bubble bath, liquid detergent and other cleansing products, and are traditionally supplied and used at a concentration of 25-28%. "High active" surfactants with a concentration of 65-70% are also available offering economies in transport and storage costs. They are also more resistant to microbiological attack and contain fewer impurities.

Manufacture of Shampoos
Shampoos are a mixture of surfactants, conditioning agents, and many other ingredients in an aqueous base. In addition to basic shampoos which simply clean the hair, there are products designed for specific hair types;“2-in-1” shampoos and conditioners; products which offer properties such as treatment of dandruff; UV protection; some degree of coloring (although most hair colorants are based on conditioners rather than shampoos); and “medicated” products. |

Manufacture of Sun Tan
Creams and Lotions
The formulation of sun tan creams is a complex science. Due to increased demand for higher sun protection factors (SPF), and restrictions on the use of some UV filters in cosmetics, manufacturing technique plays an important part in maximizing the performance of permitted substances. |
