Cleanser Formulation

The other major active ingredient in cleanser is usually some form of bleach. Hypochlorite (chlorine bleach to use its colloquial name) is the usual choice, but is put into the formula in

Aloe vera is a well-known active with good skin care properties. Fluid milks have been suggested for skin care products with Aloe vera [59]. They have good sensorics and no tacky or sticky feel. In the area of skin cleansers, the addition of a PIT emulsion to a cleanser formulation was described [60]. The result is a rather mild and non-irritant lotion for make-up removal. A similar approach describes the addition of a PIT emulsion with phospholipid to a body cleanser [61]. This product has two functions it combines cleaning and refattening properties. 

Personal Care Products The extremely low interfacial tension of microemulsions versus oil makes them very good candidates for the development of efficient cleanser formulations. Studies have been made using microemulsions for make-up cleanser applications (73), as skin cleansers to remove dirt and sebum from the skin (74), and the use of alkyl poly glycosides were shown to have excellent environmental and skin compatibihty (75) For topical cleanser applications, the flow properties are important. A formula based on...

The characteristics of interior paints that require testing and analysis include hiding and appearance, package stabiHty, adhesion, spatter resistance, flow and leveling, color and sheen uniformity, touch-up, stain removal, burnish resistance, and block and print resistance. A popular test that assesses the wet abrasion resistance of an interior paint is to measure its scmb resistance. A mechanical device is used to scmb a paint film of a specified thickness with a standard bmsh and abrasive cleanser suspension. The number of scmb cycles (back and forth movements of the weighted bmsh) at various end points (first cut through, or 50% removal of the film) is then recorded. Scmb resistance usually holds steady or decreases slightly as PVC is increased, but drops quickly once the CPVC is exceeded in a paint formulation. 

Cosmetics and Toiletries. Citric acid and bicarbonate are used in effervescent type denture cleansers to provide agitation by reacting to form carbon dioxide gas. Citric acid is added to cosmetic formulations to adjust the pH, act as a buffer, and chelate metal ions preventing formulation discoloration and decomposition (213—218). 

Skin Cleansers. Their mildness, foaming quahties, water solubiUty, and tolerance of slightly acid conditions (pH 5—6) make many of the surfactants Hsted in Table 8 attractive for use in formulating facial and body cleansers. Irritant quahties of preparations based on one or more of these surfactants can be further modified by the addition of Hpids or agents that lower the defatting (drying) tendencies of the finished product. 

The solubihty characteristics of sodium acyl isethionates allow them to be used in synthetic detergent (syndet) bars. Complex blends of an isethionate and various soaps, free fatty acids, and small amounts of other surfactants reportedly are essentially nonirritant skin cleansers (66). As a rule, the more detersive surfactants, for example alkyl sulfates, a-olefin sulfonates, and alkylaryl sulfonates, are used in limited amounts in skin cleansers. Most skin cleansers are compounded to leave an emollient residue on the skin after rinsing with water. Free fatty acids, alkyl betaines, and some compatible cationic or quaternary compounds have been found to be especially useful. A mildly acidic environment on the skin helps control the growth of resident microbial species. Detergent-based skin cleansers can be formulated with abrasives to remove scaly or hard-to-remove materials from the skin. 

Most of the CA produced commercially is chlorinated to produce SDCC, SDCC-H, PDCC, TCCA, and the double salt TCCA4PDCC. These have become standard ingredients in formulations for scouring powders, household bleaches, institutional and industrial cleansers, automatic dishwasher compounds, and general sanitizers, and most importantly, in swimming pool and spa/hot tub disinfection. The choice of chloroisocyanurate for any particular... 

The application of sulfosuccinates in the field of household products is limited. But when extremely-good wetting properties are desired the short C-chain dialkyl sulfosuccinates are used. Examples are special glass cleansers (beer glass cleaner, spectacle glass cleaner, windscreen cleaner), floor cleaner, and wallpaper stripper. The amount added to the formula is between 0.5% and 2.5%, although for wallpaper stripper up to 20% is used. A typical formulation for a glass cleaner is ... 

In the personal care market, fatty acid derivatives of proteins and amino acids (glutamic acid) are mainly used in mild shower and bath products, mild shampoos, surfactant-based face cleansers, cold-wave preparations and fixatives, baby wash formulations, as well as special emulsifiers for leave-on products. 

Personal Care Products. Within the broad definition of synthetic detergents, a variety of cleansing products are made for personal care. These include such products as cleansing bars, shampoos, bubble-bath products, cosmetic cleansers, and tooth pastes. Formulations of these products vary widely, depending upon their intended use. 

Sulfonation and sulfation processes are utilized in the production of wateT-soluble anionic surfactants as principal ingredients in formulated light-duty and heavy-duty detergents, liquid hand cleansers, general household and personal care products, and dental care products. Other commercially significant product applications include emulsifiers, lube additives, sweeteners, pesticides, medicinals. ion-exchange resins, dyes and pigments. 

Amphoteric surfactants have a variety of roles in industry today. They continue to be among the mildest surfactants available for the formulation of personal care products and are incorporated into products that demand the least irritation potential such as facial cleansers, feminine hygiene washes, no rinse cleansers such as baby wipes, geriatric products and so...
