Foam performance shampoo surfactants

In recent years, protein-based surfactants are finding some applications in personal care products due to their abilities to interact with skin and hair." A-acyl polypeptide condensates (protein derivatives) belong to the mild surfactant category with foaming performance inferior to alkyl sulfates, but they produce creamy lather and leave hair feeling soft and manageable. However, it appears that extra attention and care should be taken to ensure preservation of these protein derivatives due to compatibility with other anionic surfactants when present in shampoo formulations.

Alkyl polyglucoside carboxylate (INCI-name Sodium Lauryl Glucose Carboxylate (and) Lauryl Glucoside, Plantapon LGC SORB) is a new anionic surfactant with excellent performance for personal care cleansing applications. In shampoo and shower bath formulations the anionic surfactant shows a good foaming behavior. In body wash applications it improves sensorial effects. These properties make Plantapon LGC SORB suitable for several cosmetic applications, e.g., mild facial wash gel, mild baby shampoo, mild body wash for sensitive skin, wet wipes, and special sulfate-free shampoo applications. 

Synthetic surfactants are commonly used in shampoos, sometimes for reasons of cost and sometimes for performance. Non-ideal mixing in micelles can result when the repulsions between different surfactant head-groups are not uniform, such as when an anionic sulfonate is mixed with a non-ionic ethoxylate or when an anionic is mixed with a betaine. This causes the cmc of the mixture to be smaller than would be the case for ideal mixing, or for either surfactant alone. Such a reduction in cmc can be used to reduce the surfactant monomer concentration in a shampoo. This is an advantage since reducing the monomer concentration reduces the amount of eye and skin irritation experienced when the shampoo is used [904], Other synthetics offer other benefits. For example, some silicone surfactants can not only function as emulsifiers in hair and skin care products, but also act to improve feel, gloss, sheen, emolliency, conditioning and foam stabilization [905]. 

Also, ALES surfactant with 3-mole EO generates slightly wetter foam than either 1-mole EO or 2-mole EO sulfate. Shampoos and bubble baths formulated with ALES-3EO and Calamide alkanol-amides generate profuse foam, and the product has been characterized to be mild and gentle, and perform well under use conditions. 

Alkyl amido betaines are the most common of the betaine types. They have become the most important type of secondary surfactant, specially cocamidopropyl betaine (CAPB) [18]. It can also be referred to as coco fatty acid amidopropyl betaine [19]. Thus, combining primary surfactants with CAPB reduces skin and mucus membrane irritation [20,21], improves the conditioning properties of hair shampoos [22,23], and produces a pleasant, smooth skin feel. Formulas that include CAPB thicken more easily, develop better foam, and give a better cleansing performance than formulas without CAPB [24]. 

Owing to their excellent dye transfer inhibition properties, amine oxides can be used in a wide variety of laundry product formulations like laundry detergents, softergents, laundry prespotters, tine-fabric washes, etc. Amine oxides act as foam stabilizers and foam enhancers for anionic surfactants and therefore amine oxides are used in manual dishwash and shampoo formulations where foam volume, foam quality, and stability are important performance criteria. Some starting formulations using amine oxides are listed in Tables 66 through 70.

The sodium salts of the ether sulfates have relatively limited water solubility. They seldom perform as well as do many other anionic surfactants as wetting agents, but their foaming properties are considerably better. They have found extensive use in shampoo formulations, and, in combination with other anionic and nonionic surfactants, they are being used more for household dishwashing detergents.
