Sensomer™ 10M conditioning polymer provides smooth feel and Glucamate™ LT thickener increases the viscosity of the formula without the addition of salt. Quickpearl™ EGL pearlizing agent contributes an elegant pearlescent appearance. Carbopol® Ultrez 20 polymer decreases processing time, due to its fast dispersion, and contributes to the stability of the formulation. A formulation by Lubrizol.

Crodasinic LS95 is a mild anionic surfactant alternative to sodium laurylsulphate (SLS). Incorporation of SLS into a toothpaste can lead to disintegration of the mucin layer of the mouth by denaturing the proteins of the epithelial cells. The mild properties of Crodasinic LS95 prevent this occurrence. Crodasinic LS95 also offers distinct formulating advantages over SLS in that it is easily dispersible and does not require heating.

This O/W sunscreen emulsion gives an example of an emulsifying system and stabilizers that are compatible with the use of Zinc Oxide. In order to maximize the UV protection, the sunscreen system is comprised of TNP50T7-ATB, a TiO₂ dispersion containing Kobo's patented SPF booster SunBoost ATB and HBQP75FZS, a ZnO dispersion containing Butyloctyl Salicylate, another SPF booster. The sunscreen contains 1,48% of Butyloctyl Salicylate. Lightweight and readily absorbed, this emulsion offers good sensorial properties for a mineral-only system.

Pearl Hair Shampoo is a mild shampoo based on natural concept. It contains:

• Recrystallized Amihope LL concentrate which provides a natural pearlescent effect and improves conditioning property of the shampoo.
• Amisoft CS-22 acts as a natural cleansing surfactant.

In sensory tests, the shampoo with AMIHOPE LL is perceived as better performing in terms of foamability, finger-through during washing, hair smoothness and detangling property during rinse.

Preparation of recrystallized Amihope LL concentrate:
When AMIHOPE LL is precipitated in a surfactant solution the particle size tends to be smaller and the dispersing the LL in a liquid cleansing formulation is easier. This AMIHOPE LL concentrate is stable, suitable as a premix for various preparations.
