| Description | Lauramidopropyl betaine is a synthetic surfactant that is commonly used in personal care and household cleaning products. It is derived from coconut oil and is known for its ability to effectively remove dirt and oil from surfaces. It is commonly used in shampoos, body washes, and facial cleansers due to its gentle yet effective cleaning properties. Lauramidopropyl betaine is also known for its foaming properties, which can improve the lathering and cleansing abilities of products. It is mild and non-irritating, making it suitable for use in products designed for sensitive skin. In addition to its cleaning properties, Lauramidopropyl betaine can also act as a conditioning agent in hair care products. It can help to improve the texture and manageability of hair by reducing static and increasing shine. |

The amphoteric surfactant lauramidopropyl betaine (LAB) is a very good performing, very nonirritating, very compatible and cationic, anionic and nonionic surfactant blender. The starting compound here was LAB and the molar ratio of LAB to formaldehyde were 1:1, 1:2, 1:3 and 1:4 respectively to prepare a new surfactant and a new functional group hydroxymethyl was added to LAB. One of these is R3 (1:3) which holds foam better than the others with a foaming volume of 413mL and foam half-life of 4.73min.
Preparation of lauramidopropyl betaine-derived surfactant
· The Lauramidopropyl betaine was evaporated in a water bath until dry, dissolved in acetone, filtered at reduced pressure, and dried in an oven. 5 g of the purified lauramidopropyl betaine were measured by analytical balance. Formaldehyde quality was evaluated in the mole ratios 1:1, 1:2, 1:3 and 1:4.
· In 250 mL flasks, lauramidopropyl betaine and formaldehyde were combined, followed by the addition of 50 mL of absolute ethanol. The reaction was kept at 80 °C reflux, with a smart magnetic stirring device.
· Formaldehyde was dropped in a three-neck flask at one drop per second. The reaction solution was emptied from the flask after 3 hours, and the product separated by vacuum distillation. The end product was then dispersed in acetone and vacuum filtered out.

Oil-in-water emulsions are widely incorporated in skincare formulations due to their enhanced texture, stability, and efficacy. However, achieving effective delivery systems that can selectively direct active sunscreen ingredients to the skin's surface has seen limited success.
In this study, an organohydrogel was developed by physically cross-linking an oil-in-water nanoemulsion with chitosan at neutral pH. With the addition of a small amount of coconut oil, lauramidopropyl betaine, and glycerol successfully emulsified the active sunscreen components into nanoscale droplets that demonstrated improved ultraviolet light absorption. A straightforward pH-triggered interfacial cross-linking technique was then utilized to convert the nanoemulsion into an organohydrogel sunscreen.
The resulting organohydrogel sunscreen exhibited promising properties such as effective UV-blocking, water resistance, ease of removal, and low skin penetration. This simple methodology offers a viable route for scaling up the production of organohydrogels, making them highly appropriate for the safe application of sunscreens.
