Problems solved by technology

[0003] With the improvement of people's living standards, they gradually like to use products with gorgeous appearance added with natural plants, so formulators will add them to personal care products such as shampoos, body washes, skin care products (creams, masks, etc.) and household care products. Natural flower petals, oily ingredients, abrasive grains, walnut grains, microcapsules and other ingredients generally cannot be evenly distributed in the formula, and will sink or float; after adding traditional suspension stabilizers, the viscosity will increase, suspension stabilizers The more you add, the higher the viscosity, the poorer the product experience, and the appearance will be cloudy, affecting the appearance

Abstract

The invention relates to the field of suspension stabilizers, in particular to a high-yield-value and high-transparency suspension stabilizer and a preparation process and application thereof, and relates to the field of suspension stabilizers. The suspension stabilizer comprises the following components in percentage by mass: 5.5%-70.5% of a water-soluble monomer; 10.4%-83.1% of an oil-soluble monomer; 0-18.7% of a multi-active group monomer; 0-5.2% of a functional monomer; 0-15.0% of a graft modified monomer; 0.5-7.0% of an emulsifier; and 0.01-2.0% of an initiator. The graft modified monomer is a hydrophilic monomer and / or a hydrophilic group graft modified monomer. Compared with the prior art at home and abroad, a later grafting modification process is added, the yield value of the product is 1-5 times that of similar products on the market, the suspension capacity is higher, and the dosage of the suspension stabilizer in the same formula can be reduced by 20-50%. Meanwhile, the compound light transmittance reaches 97% or above, the suspension stabilizer is basically completely transparent and is suitable for suspended petals, frosted particles and the like of high-transparencyproducts, and the color and sensory effects of the products are improved.

Description

technical field [0001] The invention belongs to the field of suspension stabilizers, in particular to a suspension stabilizer with high yield value and high transparency, its preparation process and its application. Background technique [0002] Suspension stabilizer is a substance that keeps the large particle size, high density, and oily components in the formula in a stable state of suspension. sinking, thereby maintaining the stability of the overall formulation. [0003] With the improvement of people's living standards, they gradually like to use products with gorgeous appearance added with natural plants, so formulators will add them to personal care products such as shampoos, body washes, skin care products (creams, masks, etc.) and household care products. Natural flower petals, oily ingredients, abrasive grains, walnut grains, microcapsules and other ingredients generally cannot be evenly distributed in the formula, and will sink or float; after adding traditional...
