Distribution of finishing product groups by amount and value. 

Food processing firms producing heat-preserved, frozen, dehydrated, or chemically preserved foods may be classified by their finished products. Companies may be further grouped based on whether they process raw materials into ingredients, such as in poultry and meat processing plants, or whether they take these ingredients and convert them to ready-to-eat consumer products. 

Pew data are available on the amounts of finish remover production except for methylene chloride removers. Methylene chloride consumption by finish removal groups is estimated in Table 1. 

Cosmetics are products created by the cosmetic industry and marketed directiy to consumers. The cosmetic industry is dominated by manufacturers of finished products but also includes manufacturers who seU products to distributors as weU as suppHers of raw and packaging materials. Cosmetics represent a large group of consumer products designed to improve the health, cleanliness, and physical appearance of the human exterior and to protect a body part against damage from the environment. Cosmetics are promoted to the pubHc and are available without prescription. 

Plastic materials are predominantly synthetic materials. Since their inception over a century ago they have enjoyed a growth that has been unequaled by any other group of materials. Tliis demand continues to increase, and the facilities for meeting the new requirements are being expanded continuously. There have been good reasons for the phenomenal application of plastics in order to justify the large investments needed to produce the raw materials and to convert them into finished products.

Most synthetic and natural polymers degrade when exposed to solar ultraviolet (UV) radiation (1-5). In synthetic polymers degradation is generally caused by the presence of photosensitive impurities and/or abnormal structural moieties which are introduced during polymerization or in the fashioning of the finished products. The presence of groups such as ketones, aldehydes, peroxides and hydroperoxides are implicated in polymer degradation (1-5). 

For some of the effects the concentration in the products is most important, for example, the local tolerance on the skin and eye. For some of the other effects it is necessary to estimate the presumed use by a normal or perhaps an eager user and the total amounts are more adequate. Guidance to relevant exposure estimation can be found in part 6 of SCCNFP. Safety evaluation of finished products in the notes of guidance.3 The European cosmetics industry has, for example, estimated the exposure levels to be 0.8 g/day of face cream, 1-2 g/day of general cream and 8-16 g/day of body lotion for a female user.10 It is also important to predict the use of the special product and the expectations from the single user. Groups of users with especially sensitive skin are important to take into account. 

The weight ratio of the water and etherified product sent into the tower should be 1 10. During the hydrolytic condensation the mixture is sampled to determine the content of chlorine, butoxyl and hydroxyl groups and the flush water is tested for acidity. The finished product should have not more than 2% of chlorine, 15% of butoxyl groups and 3% of hydroxyl groups. If the chlorine content is above the norm, the product is subjected to repeated hydrolytic condensation. 

The finished product is polynonylsiloxane with not more than 1% of hydroxyl groups and at least 2.5% of butoxyl groups there should be no chlorine. In case it contains chlorine or more than 1% of hydroxyl groups, polycondensation should be continued for 1.5-2 hours at 250-260 °C. The total amount of the distilled solvent and volatile substances during the distillation and polycondensation is 60-70%. 

Acetic anhydride or vinyl acetate Not more than 2.5% of acetyl groups introduced into finished product...
